Records Search 1. Obtain Title History - The complete title history of the site is being compiled by The Chicago Title Insurance Company located in Tustin. A sketchy history based on the data avail- able at this time is as follows: a. R. E. Boucher. b. Mr. Ralph Gray. C. Mr. Stevenson (operated vacuum truck service for transfer rotary drilling mud - no records of operation remain) . r d. Mr. Bob Wainer and Mr. Howard Ricky, et al (operated as only Class III facility - no known records of operation) . e. Mr. Tober (non-operator - sold site to F. Mola) . ' 2. Interview Prior Owners/Operators of the Site - An attempt is being made to locate the previous owners and operators and r obtain information concerning the nature of the materials deposited. Mr. . Stevenson and Mr. Wainer, the most recent, known owners of the subject site, were interviewed on January 30, 1980, and January 28, 1980, respectively. Mr. Wainer (et al) was the r last owner/operator of the facility. He indicated that the site was operated in accordance with the rules and regulations covering Class III facilities, although Orange County EMA files (Water Resources) indicate that the operators were cited numerous times for allowing organic matter deposits (land- scaping wastes) . The only records he was aware of were the r CRWQCB files, which were apparently destroyed in a fire ap- proximately five to six years ago. Mr. Stevenson indicated that he allowed only rotary drilling mud to be deposited on-site during his ownership of the site. During that time he also operated a vacuum truck service for r transfer of materials. Mr Steve____n_G.an indicated that and files concernin the e were removed, and resumably destroyed, roughly three or four years after he sold t e site. e a so said that he had no records of the vacuum truck operations during this time period. r According to Mr. Stevenson, most of the chemicals on the site (e acid �nd� ma s wer erLon-site during the 1940's prior to his ownership Mr. Ralph Gray was thought to have owned the site during this time, although all attempts to reach him have proved fruitless. If he is still alive he should be well into his 80's according to Mr. Stevenson. r . 3. Review Governmental Data Files Concerning the Site - The most salient data from government files is provided in Appendix A. -1- a. City of Huntington Beach Public Works Department (Mr. Bob Allen) - City .files indicate that it took nearly seven years for t11s:_publ o__e notified of the un- ealthful condition of local well water after the County had recommended the wells be aban one—l. b. Orange County Environmental Management Agency, Water Resources Division (Mr. Jim Roberts) - Orange County EMA Water Resources Division files contained several analyses of ponded materials on-site, as well as samples taken directly from trucks visiting the site during the early . 1950's. This .information is also attached for your review. In 1954 the County investigated several rumors that oil and sulfur had been dumped on 'the site illegally and found them to be false. c. California Regional Water Quality Control Board (Mr. John Zasazinski) - The files wer Gt ov approximately eight years ago. B. Topographic and Soil Profile Investigation to determine the area and volume of suspect materials. 1 . USGS maps (1935 and 1965) - no appreciable difference in topography was noted. 2. Interpretation of Available Aerial Photographs (1927 - 1969) - The aerial photographs in Appendix B are summarized below: a. Figure B1 1927) : Natural terrain; no dumping or develop- ment had taken place. b. Figure B2 (1934) : The northeast area of the site had been graded to some depth below the natural topography, as evidenced by the dark shadow of a bank trending north- south in the central-northern portion of the site. C. Figure B3 (1947) : Deposition of dark sludge materials had occurred. At least three separate pools can be distinguished. d. Figure B4 (1953) : The sludge pools are still discern- able. They do not appear to have grown appreciably in size and they seem lighter in color, possible having soaked in somewhat or been covered with dirt fill. e. Figure B5 (1960) : The sludge pools were covered with nonpetroliferous fill materials. The darkness of the landfill surface in places was most likely caused by the new fill material soaking up the deeper sludge deposits. -2- f. Figure B6 (1964) : Most of the eastern and central areas of the landfill had been overgrown with vegetation, although there were several bare patches and the outlines of the original pits can be vaguely detected. The most recent dumo�np s to have occurred in the western portion of the landfill. g. Photo not reproducible (1969) - A brownline reproduction of a 1969 aerial photograph of the site vicinity was also analyzed. Although the quality of the photograph was M poor, the condition of the site appears to have been largely unchanged since 1964. Some new dark areas showed up in the northwest area of the site, possibly shadowing or new tree growth. 3. Historic Maps and Personal Photos of the Site (see Appendix C) a. Figure Cl (1963) : This figure was developed by Valley Engineering based on a survey of oil sludge deposits on the site. It shows the geographical limits of the oil sump area and the locations of pools of greater than average depth in the northeast corner of the site. b. Figure C2 (1955) : This oblique view of the site was obtained from the files of the Water Resources Division of the Orange County Environmental Management Agency. It provides a close-up of the sludge deposits still on the ground surface, and the banks of the landfill. 1 C. Figure C3 (1963) : This oblique aerial photograph, from the same source as Figure C2 above, shows that vegetation had grown over much of the landfill site. Near the east site boundary the ground surface is still stained and devoid of vegetation. It appears that some dumping of ' dark liquid wastes could have occurred at some time in the center of the deep pit in the northwest corner of the site. This would account for the finding of sludge materials by Boring No. B-10 (see Figure D4) in the northwest portion of the site. 1 4. Review of Available Soil Reports for Projects on or Adjacent to the Site a. On-Site Soil Conditions - The following reports provided in Appendix D, were reviewed concerning existing soil conditions on the site: / Preliminary Soils, Foundation, Engineering Geologic and. Seismicity Investigation, Action Engineering Consultants, October 31, 1978. Hazards Report, Jack K. Bryant and Associates, Inc. , 1 November 5, 1979. -3- 1 Based on extrapolations from the well log data in these reports, four generalized soil cross sections were pre- pared (see Figures D1 - D3) . Figure D4 shows the ap- proximate locations of the cross sections on the site. The cross sections show the depth of the landfill and the areas of potential 'contamination. The latter are those areas which were found to contain "petroliferous" sludge materials. The cross sections largely reflect the locations of sludge pools when the site was being used as an oil sump (see Figure D5) . The two major inconsistencies in the cross sections are the discovery of sludge material by Boring B-10 (Figure D1) and the presence of such material on the ground surface at Boring B-17 (Figure D2) . b. Soil Conditions Adjacent to the Site - Cross Section E (see Figure D6) was prepared using trench data from the following report, which is provided in Appendix D: Earth Research Associates, Seismicity and Fault Investi- gation, Tentative Tract No. 9235, July 28, 1976. Tentative Tract 9235 has since been developed with -,E�oirdr-- dma-a uM. The cross section (see Figure D4 for location relative to the site) offers further evidence of sludge materials on the ground surface. In addition, some "petroliferous" material was identified in the natural ground near the northeast end of the trench. Due to the shallowness of the trench, it is difficult to determine the exact origin of the sludge intrusion. However, it is possible that subsurface movement occurred in an easterly direction from the project site and welled up in some areas. PHASE II -- ESTABLISH METHODOLOGIES FOR SAMPLING AND ANALYSIS OF SITE SOILS AND SUBSURFACE GASES A. Sampling Methodology - A sample size of 20 core holes was selected based on cost constraints and accepted geological testing prac- tices. The 20 core holes can be divided into two categories: those which will sample both gases and soils, and those which will be used to obtain soil samples only. 1 . Gas/Soil Sampling Core Holes - Nine core holes will be spaced as shown in Figure E1 in order to maximize the efficiency of gas sampling. Since the proposed gas testing procedure samples from a circular area within a 100-foot radius of the core hole, this arrangement will allow 100 percent sampling of gases in the former landfill area. In addition, the gas samples near the east site boundary will provide gas data for the adjacent condominium development. Soil samples will also be collected from these core holes. -4- 2. Soil Sampling Core Holes - The remaining eleven core hole locations will be distributed over the site according to one of four alternative strategies (see Appendix E) from which the State will choose the most desirable plan for implementation. a. Equidistant Sampling (Figure E2) - The samples are dis- tributed at approximately equal distances between the nine fixed core hole locations. b. Random Sampling (Figure E3) - The former landfill area was divided into a 50-square-foot grid. Numbers were assigned to all squares not containing one of the nine fixed core holes and eleven of the numbers were selected randomly by computer. C. Weighted Random Sampling (Figure E4) - Sampling was . confined to the northeast corner of the site where aerial photographs indicate that sludge deposition took place. The area was divided into a 40-square-foot grid. The grids containing portions of the deeper sludge pool areas indicated in Figure E4 were assigned one set of numbers and the remainder of the site received a separate nu- merical assignment. Six of the core hole locations were randomly selected by computer out of the first set of grid squares and five were selected out of the second set. Grid squares containing one of the nine fixed core hole locations were not included. d. Inductive Sampling. (Figure E5) - The core hole locations were selected to aximize the likelihood of finding sludge deposits, based on information obtained from studying aerial photographs and existing geological data for the site. . B. Analyses Anticipated by the State Based On Current Data - 1. Solid/Sludge Samples a. Sampling Plan - Samples will be taken from preselected locations with the use of a bucket/auger type drill rig. Split samples will be provided. A State field investi- gator will be present to monitor operations. b. Lab Analysis Plan - A State approved lab will conduct the following analyses of soils: i. Aliphatic hydrocarbons ii. Aromatic hydrocarbons (especially benzene) iii. Chlorinated organics iv. Heavy metals (per State list) v. PCB's -5- 2. Well Vapor Samples a. Sampling Plan - Calculations indicate that 9 wells will be required for site coverage. The gas test well and tip assembly are to be constructed as shown on Figures F1 and F2 in Appendix F. 0 b. Lab Analysis Plan - A State approved lab will provide the following analyses of vapors during a four-week period (9 wells x 2 tip assemblies x 4 testing periods = 72 samples) . i. Aliphatic hydrocarbons ii. Aromatic hydrocarbons (especially benzene) iii. Chlorinated organics ° iv. Organic Pb, Hg, Se v. Organic sulfur vi. . H2S C. Statistical Analysis of Sample Significance - A qualified profes- sional statistician will perform a computer analysis of the chemical data which is obtained through core sampling of site soils in order to determine confidence intervals for the mean and variance of the sample data. Population distributions of chemical data for the entire site and the yrobabilities of a hazardous substances exceeding safe levels anywhere on the site will be estimated as acc�ratelyasrpossible,s The actual statistical test which is used will depend on the characteristics of the core sample data. Pos- sible tests include the following: 1. Test of mean (t test) 2. Test of variance (x2) 3. Test of normality (x2) 4. Tchebycheff`s inequality test D. State Approval - State approval of Phase II is required. PHASE III -- IMPLEMENT SAMPLING AND TESTING PROGRAM A. Measure and Mark Locations of Sample Borings - This may be done up to three days before the scheduled drilling is to take place. A noncontaminating material will be used for identification of drill sites on the landfill surface. B. Drilling and Sampling Operations - The anticipated schedule re- quires approximately 3 days of drilling for soil samples and vapor well placement. A State field investigator will be present during the drilling phase for split sample selection and observation of drilling procedures and well placement. 1. Soil Samples - 20 composite soil samples will be taken ac- cording to the boring schedule (per Phase I B) and locations (.per Phase II A 2) . The samples will be placed in glass containers for immediate delivery to the laboratory for analysis. -6- 2. Gas Samples - 72 gas samples will be taken from 9 wells. Each well will have 2 tip assemblies: one at a depth of 5 feet and one from 10 to 15 feet depending on the level of perched groundwater. The samples can be drawn seven days after well placement. Thereafter, each gas well assembly will be tested once every seven days for four weeks. PHASE IV -- IMPACT ANALYSES A. Statistical Analysis - The analysis of sample significance will be performed (per Phase II C) and the findings reported. B. Discussion of Lab Results, Acceptable Standards, and Potential Impacts - 1. Minimum - Qualitative analysis (i.e% , air, water, soils) . 2. Maximum - Quantitative anlaysis (i.e. , modeling of potential emissions and/or leachates) . C. Meet With State to Discuss Findings PHASE V -- MITIGATION MEASURES BASED ON THE RESULTS OF PHASE IV B 1. Minimum - Qualitative discussion of recommended general measures to be applied. 2. Maximum - Environmental engineering. -7- CHRONOLOGY OF EVENTS 1927 Oldest available aerial photo shows the site existing in a natural condition (i.e. , relatively flat site except for a depression trending in a northeasterly direction toward the upper reaches of Bolsa Bay. 1934 Aerial photo shows evidence of gravel operations in north- eastern portion of the site. 1935 Oldest available U. S. Geological Survey topographic map depicts a depression in the northeast portion of the site with a depth below the elevation of 20 feet. 1940's The gravel pit was enlarged during this period, while at the same time a variety of. refinery type wastes were deposited (i.e. , acid sludge) . 1945 Groundwater falls below sea level and salt water intrusion begins. 1947 Aerial photo shows evidence of ponded material. 1950 Stevenson Bros. requested permit to deposit rotary drilling muds on-site. 1950 Mr. Loren E. Blakelev. C.E. , took 200 samples of soil and water in and around the site in order to estimate the extent of pollution and permit conditions for supervisors. This, report indicated that the groundwater was unfit for either domestic o irrigation— es. Indicates that the southerly pit as seen in the 1947 photo) contained acid sludges while the easterly pit contained alkali sludge materials. Groundwater was described as highly acid mineralize with strong gasoline W , (range hydrocarbon odor. 1953 Stevenson Bros. granted permit to deposit drilling muds. xcavation maps required as part of the use variance; also agreed to use only south and east pits for filling. 1955 Mr. .E. L. Russell, M.D. (Orange County Water Pollution) indi- cated that contamination is a result of chemicals deposited prior to 1946. 1955 Photograph of the site from the northern project boundary shows materials ponded behind a dike constructed along the site's northeastern boundary. Two (2) old barrels, of unknown origin, are seen in the center of the picture (just above the words "sludge materials") . 1955 Surface samples of southern pond material indicated a pro- nounced sodium sulfate character and strong petroleum odors as well as the following levels of constituents (OCWR) : -s- CA 6.Oppm CO3 0.0 ppm Phenols 0. 1 Ng 93.7 ppm HCO3 232 ppm Total Solids/ppm 4099 Na 1200 ppm SO4 1814 ppm pH 7.3 K 33.5 ppm CL 645 ppm Total Cations 6169 NO3 10.5 ppm Total Anions 60. 11 1955 Samples from 2 trucks on-site showed the following: CA 97/102 CO3 0/0 Mg 5/7 3 53 NA 325/330 SO4 48/48 K 14/14 CL 457/447 Total Cations 19.7/17.2 Total Anions 16.5/16. 1 . 1955 Area residents begin to complain about groundwater with a garlic or petroleum taste and gassy odor (OCWR) . 1960 Santa Ana Regional Water Pollution Control Board discusses project site - no action taken. 1960 Aerial photo shows fill material covering northeasterly por- tion of site. Slopes indicate it still exists as a depressed area. 1961 The odor constituents of well 28D4, slightly to the north of the site, were identified as 0.6 mg/l Mercaptan Sulfur and 3.0 ppm tentatively as acetylene (Terminal - DWR) . 1963 The project site was designated a Class III landfill. 1963 Oblique aerial photo shows depressed nature of the site. The old dike along the site's northeastern boundary is clearly visible. 1963 Valley Engineering investigates project site, estimates volume of sludge as 2,000 cubic yards, covering 22% of the site to an average depth of less than one foot (i.e. , 0.2 to 0.3) . Three deeper areas were noted with depths of 1 to 5 feet (T. S. . Carlsen) . 1964 Groundwater now- above sea level and salt water intrusion and flow of subsurface pollutants to the northeast is reversed. However, water quality analyses still�S_hQw cnntam;nat n_ Montgomery).. 1965 U. S.

Thereafter County Lab (PJB)_' detects PCB levels to be less than 200 parts per billion. 1979, Orange County Public Health investigates 6 + water wells adjacent the site and find PCB levels to be less than .005 per billion (R. Hall) . 1979 Surface soil samples taken by the State show PCB levels as nondetectable (J. Stalher). -10- APPENDIX A ' GOVERNMENT FILE DATA 1 t Consulting Civil Engineer q 1112 Filson Prive Santa Ana, California 1 Pecember 4, 1950 Honorable Board of Supervisors County of Orange Re: Progress "eport . Santa Ana, California Bolsa-Chita Dump Gentlemen: Att.ach,ed Hereto is a summary sheet, Hiving results of chemical analyses made to date under an agreement reached with Steverson Brothers, Orange County, the Regional Water Pollution Control Board, the St.at.e Pivision of Water Resources, and the industrial Waste Committee of the Western Oil and Gas Association. This survey of existing conditions was undertaken to determine what terms and conditions should be imposed by the County of Orange under Ordinance No. 536 in granting a permit to dispose of drilling mud and formation material in this old dump area, under terms of a use variance granted by the Planning Commission and the Board of Supervisors tI S•teversIn Rrothers. It was nec,essary to drill snrnt' nine t��_t holes inortic to ►'clumine under� ronnr► CgntltlOn� in the ,►rca ro osed f . waste di s osal, ° orr than 200 same tit samples of soi 1 and t p � p rr' t ntpn ill order to determine the type and extent. of golluti.on in the various strata of, clay, silt and sand which were enco►►nterel _ As pointed out in my first report on around water conditions in th? vicinity of this dump, there is a general northeasterly movement of polluted ground water in thisarea. Samples from holes 2, 3, 4 and 5 can be taken as typical o the north and east. sides of the present tank bottom-crude oil visible dump. Ground water from these test holes- is f r either domestic or irrigation use an�c isa_ Ae 7nte—Tf�reai? to the surrounding lands which_ are entirely dependent on underground stored-water-for their supply,._, As indicated by its alkali coefficient of 100.2 inches (the amount which could be evaporated from a four-foot colume of soil without leaving enough chemicals to injure sensitive plant, roots) , the only entirely unpolluted water in the vicinity is found in hole Q This hole was located in the bottom of the one-acre tree covered old gravel pit. near.est _to Bolsa-Chita Avenue, (tole 2, located on Mr. Anderson' s land at the east end of the dump area, has an alkali coefficient of only 3,0 inches due to the type and amount of dissolved chemicals found in Around water at that point. i Hoard of Supervisors Pecember 4, 1950 Page 2 Mien work on this problem was first started it was I.hourlht that acid sludge had been put in pits on the south sine of the dump, and alkali sludge in one pit at the east end of the damp. No one ex— pected the appearance of highly acid mineralized ground water with strong gasoline-range hydrocarbon odor at the 1\111 corner of the present damp. This indicates either long travel underground, or additional deposits of acid sludge on the property at. unknown locations. All Mied with disposal of industrial waste and pro— _CLLwater esources wt t r w tom rave c t scussed the gat a are of the o .inion that it, is unwise merely to cover up the present stir .ace of t1�eoa n1. with mu our cut.ttngs Wlt lent some attempt to 1 i m i t ?uture pollutis rLround wa eises an a s to Llre lrresent ly known polluted soil formations . Several rneans of correcting the existing �! Eo ncl`i`f on and drawing up specifications for operation of a satisfactory dump have been discussed with Mr. Steverson, Mr. Anderson and others. No cost estimates have been prepared. It is now a proven fact that these various soluble chemical wastes uo as deep as fo fee from tJte surface, and pass on throujr alternate layers of what is normally called clay, dry silt, silt., soil , sand, and gravel before reaching an underground water—bearing stratum. This fact makes it imperative that ways and means be found to minimize future pollution from this known source, and to prevent, further pollution • of Orange County°s dimini.shing supply of usable ground water. Appropriations heretofore made by the Board have been expended in obtaining working agreements with the various parties interested in solving the problem, obtaining samples and basic data, and making necessary field surveys so that the information oiitained can properly be analyzed and reported. The samples are stored. Work on this problem has now stopped because alloted funds have been expended. Since there are several applications for drilling fluid dumps now pending it is advisable that an adequate appropriation be made to determine existing conditions at such dumps, and to draw up specifications for construction and operation of future ones. Under such a program a part. of Steverson Brothers land can be put to beneficial use while further work is done on the more difficult problem found in the east part of the property.

BOLSA CHICA MESA WATER QUALITY STUDY i i A. INTRODUCTION On November 6, 1973, the Orange County Water District requested that James M. Montgomery prepare a brief water quality study of ground water problems in the Bolsa Chica Mesa area of Huntington Beach, OCWD Task Order No. 6- 1140-47-74 (JMM Job No. 116. 11). These studies were undertaken in part because, of the marked changes in mineralization at well 5S/11W-20K3 (Mrs. J. Campbell, 16632 South Delores, Huntington Beach, California). Work on the task was to include the collection of available background j material including lithologic logs, water level and water quality data 3J in the Bolsa Chica Mesa area. Specific task activities are outlined as follows: Review existing reports. Review historic water levels and water quality variations in the principal cr pertinent aquifer zones. Evaluate source or sources of water quality impairment. Present findings in a brief letter report to include the definition of water quality problems, findings and conclusions relative to the source of impairment, an outline of possible solutions or remedies, and recommendations for further investigations, testing and/or monitoring. H.' 1t`j'q• 'V . V CONDUCT OF THE STUDY In order to develop an understanding of past and present ground water quality features in Bolsa Chica area, basic hydrologic data was collected from the District's files and from the California Department of Water Resources and Orange County Flood Control District. Geologic sections or profiles were drawn of the multi-layered aquifer system and hydrographs of water surface elevations in several of the prigcipal aquifer zones. Ground water analyses for five aquifers were reviewed and selected wells were resampled and waters analyzed. The history of waste disposal at the Bolsa Chica (Boucher) dump was reviewed and records of taste and odor problems in adjacent water wells were studied. Results of these studies are described in this report, and are depicted on the attached Figure 1 and on Plates 1 and 2. As denoted later in this report, subsurface hydrologic and water quality conditions in the Bolsa Chica Mesa area are complicated by the geologic structure, and by the existence of numerous separate and individual A aquifer zones. These include from the surface downward the Serniperched, Alpha, Beta, Lambda, Meadowlark, Main and "Lower Zone" aquifers (Plate 2). For convenience in evaluating present and future ground water quality problems, wells of major interest in the area have .been classified relative to producing zone. These wells are listed in Table 1. HISTORY OF WATER QUALITY DETERIORATION . The period from about 1937 to 1945 was a time of above-normal precipitation on the Orange County coastal plain. Water levels in the Bolsa Chica area were generally above sea level due to increased recharge in the coastal plain forebay area. After 1945, piezometric levels began to decline as a result of an extended period of predominantly subnormal rainfall. Ground water levels were lowered to elevations below sea level and remained generally below sea level from the early 1950's until 1964. In early 1949, sea water intrusion wets noted beneath Bolsa Chica Mesa in the Alpha and Beta aquifers (Well 5S/ 11W-29C4. Saline waters had moved inland across the Newport-Inglewood fault zone under the reversed t_ hydraulic gradient (see Plate 1). By 1955, saline intrusion had moved �J inland about 2, 400 feet (5/ 11-20Q3) in the Alpha aquifer, and pressure levels in the Alpha had declined • locally to 35 feet below sea level. As a result, intrusion increased rapidly across the Newport-Inglewood fault in the Alpha and Beta aquifers. However, the Bols�a-Fairview fault limited , the saline advance once the intrusion front had reached that fault. Fortunately, the underlying Main aquifer was not found anywhere to be intruded and maintained chloride ion concentration of less than 25 mg/l, even at its seaward-most extent near the Newport-Inglewood fault. After about 1964, rising ground water levels associated with increased forebay recharge resulted in the seaward retreat of the intrusion front and local wells in the Alpha aquifer experienced a decline in chloride ion concentration. However, as shown on Figure 1, ground water levels in the Alpha aquifer on Bolsa Chica Mesa again began a general decline in late 1969 and 1970. 1 Taste and odor problems associated with the disposal of liquid wastes on Bolsa Chica Mesa have been observed to cause significant local ground water quality problems. Based upon files contained ui the Orange County Water Pollution Deuartment and the California Department of WatRes ources, waste liquids were discharged at a number of sites on Bolsa Chica Mesa during the development of coastal oil fields along the Newport-Inglewood structural zone. .� Perhaps the most conspicuous and well-documented disposal site is the so-called Bolsa Chica Dump, located in a canyon about 1, 000 feet southeast of Warner Avenue and Bolsa Chica Road. The area is now designated as the "Boucher Dump" on Plate 1. The dump was originally -3- a northeasterly trending canyon in the mesa which had formed from erosion ,1 and ancient spring-flow. Prior to 1950 the old canyon was enlar lei d a, J gravel pit, while simultaneously being used as a s"t� e for the discharge of refinery waste, acid sludge and other oil and chemical wastes. The presence of these substances in subsurface sediments around the dump was verified by' Blakeley in 1950. < Nine test holes were drilled at that time and more than 200 samples of soil and water were collected and analyzed. From those samples, local sediments and ground waters were found to be significantly degraded in terms of total dissolved solids, sulfates, color and odor. Odors y from samples were described as "earthy", "gasoline range hydrocarbon" and "foul chemical". These odors within the sediments extended to about 40 feet below ground surface. In 1953, Steverson Bros. Inc. was granted a permit to discharge fresh, 7 clay-base rotary drilling mud in the same disposal site. However, in 1955, samples of waste liquid in the disposal pond exhibited total dissolved solids of 4, 099 mg/l, a pronounced sodium sulfate character and strong petro- leum odors. The same year, a water well west of the old dump beganto produce ground waters with a gaseous ("gassy") odor and petroleum or garlic taste (5/11-28D4). Increasing numbers of shallow domestic water wells to the north and west also pumped_gy_o�nd w_a.t.ers with gaseous, petroleum or garlic odors between 1955 an 1 g6; Discharged waste liquids had apparently reached the zone of saturation and had moved northward under a landward hydraulic gradient. In 1961, odor constituents in Well 28D4were identified in laboratory analyses (Terminal - DWR) as 0. 6 mg/1 Mercaptan Sulfur, and acetylene. -Ultimately,— waters from more than 12 shallow wells near the dump were to exhibit similar - *L. E. Blakeley, "Progress Report on Bolsa Chica Dump", December 4, 1950 (Orange County Water Pollution files). -4- taste and odor problems. These wells are listed on Table 2; their location and the extent of the odor problem is shown on Plate 1. r In 1963 the Bolsa Chica Dump was reclassified to receive only inert solid waste materials (Class III), such as earth, rock, glass, concrete ------------------ etc. The last report on the occurrence of gaseous, garlic odors in ground water was made in 1965. In shallow wells such as 28D4, quality improvements seem to have resulted from the re-establishment of a seaward hydraulic gradient in the late 1960's (Figure 1). In many other wells, data is not available because periodic sampling and well monitoring were almost completely discontinued in the late 1960's, r The results of past disposal of brine to the ground surface has also been Iobserved near Warner Avenue and the Newport-Inglewood fault (south branch), and near the intersection of Warner Avenue and Algonquin Road. Discharged dliquids were of high salinity (+30, 000 mg/l, TDS) and locally exhibited a petroleum-like odor. It is considered likely that numerous other oil brine f discharges were made periodically to the Bolsa Chica Mesa surface during the development of the Sunset Beach Oil Field. i - It should be noted that natural sulfur tastes and odors, and amber color have long been associated with deeper waters from the lower Pleistocene sediments (Main and Silverado aquifer zones). These conditions have -1 occurred in deep wells along the Newport Inglewood uplift from Costa Mesa J to Long Beach and are considered to be native to those aquifer zones. As shown on Plate 1, numerous wells on the mesa have been abandoned or destroyed, in part because of quality problems including taste, odor and salinity. It is estimated that within Sections 20 and 29 alone, more than -5- l 1 TABLE 2 WELLS EXHIBITING PETROLEUM-TYPE ODORS Depth Total Dissolved Well No. (ft) Year Solids (mg/1) Odor i 5S/11W-201<2 65 1962 1932 Petroleum j 1963 2284 (none) 1964 1614 (none) 20Q5 120 1965 3720 S1. petroleum 1 20QII 100 1965 398 S1. petroleum J 21M7 175 1965 462 S1. odor 21N2 1961 +425 Mercaptain-like odor J 1962 +420 Gassy odor 1963 +420 Gassy odor 1964 358 Garlic odor 1969 397 (none) 21N3 1956 +330 Gassy odor 21N4 135 1958 576 Gasoline-ammonia odor 1963 496 Petroleum odor 1965 240 Petroleum odor 21N5 145 1961 418 Mercaptain-sulfur odor 21N8 120, 1964 502 Garlic odor 1968 496 Garlic odor 28D4 125 1955 838 Petroleum I 1955 842 Gassy odor 1956 677 Garlic odor 1957 500 Petroleum odor 1958 1309 Gassy odor 1959 885 Gassy odor j 1960 1444 Gassy odor 1961 944 Gassy odor 1961 1472 Garlic odor 1963 1391 Gassy odor 1964 458 (none) 125 1965 542 Petroleum odor 1967 485 (none) 1969 573 (no ne) 28D5 125 1965 400 Strong odor 28D6 95 1964 694 Mercaptain odor J 50 shallow water wells were abandoned between 1950 and 1973. The availability of imported supplies and the current rapid change in land use from agricultural and suburban to urban multi-unit type developments will probably result in the ultimate destruction of most of the remaining shallow domestic wells (unless some of these wells are preserved for monitor- ing purposes). CURRENT CONDITIONS In the Bolsa Chica area, ground waters within the shallow Semiperched aquifer are locally in hydraulic continuity with saline bay and harbor waters, and have exhibited a general increase in chloride ion concentration landward of. the Newport-Inglewood fault zone since 1965. This trend is most pronounced at 20E4 (HH-2C) where concentrations have increased from 400 mg/l in 1965 to 11, 663 mg/l in 1973. Smaller increases have also occurred in Well 20M5 (BSO-6D), 20N3 (HH-4C), 29G7 (HH-5C) . and 29C8 (HH-5D). Slight improvements in quality occurred at 20M8 and 20N4. These changes in the Semiperched zones have little effect upon the underlying Alpha aquifer because these two aquifers do not appear to be hydraulically connected locally. In the Alpha aquifer between the Newport-Inglewood and Bolsa-Fairview faults, - quality trends have been mixed, showing both increase and decline of chloride ion concentrations between 1965 and 1973. However, just seaward of the Bolsa- Fairview fault, waters from several wells have risen markedly in salinity since 1965. Well 20Q5 and 20Q11 have increased from 3, 872 to 7, 196, and 65 to '- 298 mg/l, respectively. An adjacent well, 20Q3 which produces from the same aquifer just inland of the fault, remained about constant from 1965 L to 1973 (241 to 267 mg/l chlorine ion). To the northwest, also just inland of the fault, water from Well 20Q6 has increased from 65 to 290 mg/l in chloride ion concentration. Test wells within the Alpha aquifer adjacent to 6 1 In 1954 a small domestic well tappin;, the Semiperched zone (65 feet in depth) was drilled at a location about 200 feet west of the Campbell well. The shallow well was sampled five times between 1961 and 1964. During that period, analyses show the Semiperched zone waters to be significantly more mineralized than the underlying Alpha aquifer with total dissolved solids ranging from 1, 400 to 2, 284 mg/l, chlorine ion content from 455 to 714 mg/1 and nitrate concentrations from 7. 4 to 30 mg/1. J l An increase in nitrate concentration is generally not associated with marked increased in chloride ion concentration in ground waters degraded by sea 'intrusion.intrusion. For example, wells 20M2, 20M6, 20N1, 29C5 and 29C6 --------------- 1 have all yielded ground waters from the Alpha aquifer with chloride concentrations exceeding 10, 000 mg/l, but all exhibit nitrates of less than 0. 22 mg/l. Similarly, analyses of the saline waters from the ocean and from the tidal sloughs in the Bolsa-Sunset area (Table 3) exhibit essentially no dissolved nitrate. Nitrate concentrations exceeding 10 mg/1 appear to be associated solely with surface and shallow Semiperched waters, such as the former Huntington Harbour spring designated 20ES-2, and wells 1O1311, 20K2, 20M8, 20N4 and 29C8. CONCLUSIONS Based upon the evaluation of basic water quality data described in this letter report, the following general conclusions have been made: 1. With the decreasing values of the ground water "recharge to extraction" ratio in the coastal plain since 1970, a landward hydraulic gradient has been locally reestablished in the Alpha aquifer. As a result, the potential for sea water intrusion again exists in the Bolsa Chica area. - ,i -8- lTA 1.3LE 3 MINERAL ANALYSES OF GROUND WATERS AT BOLSA CHICA MESA per Lit Well TernP Chemical Con at,lue nta in hltll+R ra ma er Numhcr when and Date Sampler F:C W '1'll a• Akin ler Sampled of pll 25-C Ca AfR Na K CU) III:., 504 CI NOJ F 117Ds Cal:O Sampled 55/IIW 19B7 8/1.161 70 B.1 900 68 IS 104 1 0 201 67 I55 0.0 0.4 0.10 540 211 Alpha 19B4 . 8/14167 70 7.9 720 64 11 71 3 0 192 75 96 0.0 0.4 0.10 ISO Z05 Alpha I9 B7 8/15/63 10.9 8,101 497 36 1,325 33 15 0 255 2,766 0.0 0.1 0.17 6,100 1,1tl9 Sem1 Perched 19B8 9/8A4 •- 8.0 650 32 24 69 4 0 212 49 74 0.0 0.4 0.11 370 199 Alpha 19 n9 9/8/64 8.0 850• 49 25 95 4 0 221 62 141 1 0.0 e 0.4 0.04 552 226 Alpha 55/IIW 19B10 \ 8/3/64 -- 7.9 1,300 58 84 73 4 0 202 68 305 0.0 0.2 0.04 732 490 Alpha . 19B I I 813/64 -- 8.0 6.000 697 131 385 11 0 169 136 2.046 0.0 0.1 0.35 4,282 2,279 senu Perched 20E2 8/3/64 7.1 I,191 117 57 113 2 0 111 191 141 16.0 0.8 0.15 1,616 727 semi Perched 20E4 7/29/64 1,300 41h I,682 semi Pe r,1„�d 3/]165 2,1tl1 4J0 I,640 s,;mi Perched 4/20/72 29,200 to,031 - Sc,nt Pc rc h,-d I o/13/71 35,000 11.661 24,60E Scmi Pe,,hed 20E5 7/27/64 671 4-1776 Alpha 3/1/65 6Z5 40 390 Alpha 4120/7, Z,130 204 - Al 10/11/71 -- 1.590 202 944 Alpha 2007 117/64 7.9 440 49 10 3) J 0 Z14 36 14 0.0 0.2 0.08 244 164 Alpha SS/IIW 20J9 IZ/IOl7J 665 19Z 43 c0.21 I.-hda 20110 2/26/65 69 tl.7 450 )J tl 50 3 IC 174 42 42 0 0.6 0.07 260 116 ltr la 20K2 2/1/61 •. 7.6 Z,100 7.51 60 96 2 0 111 211 '411 10.1 1.1 0.1E - se„1,I'.rrh•d 12/19/6Z 7.7 1,050 271 97 111 6 0 4" Z10 661 14.1 0.1 0.14 I,712 se,,., P•r,.h e.1 6/21161 7.6 2,900 178 39 '245 6 0 403 1S9 714 7.4 1.1 0.1 '2.284 S•n,1 F'•rche•1 I/tl/64 8*1 2,175 I36 117 197 6 0 395 111 511 11.0 0.2 0.14 I,688 se nn P,rrh•••1 7/20/64 tl.0 2,J00 218 92 157 5 0 116 LI1 52J 14 0.1 0.24 1,611 Se-1'e rchcd 20K3 Z/1/61 7.7 405 52 5 27 1 0 197 )2 li, 0.0 0.5 0.11 288 Alpha J/I1/64 8.2 )95 15 IS 14 1.1 0 19n 40 I1 0.0 1.4 0.OS 153 Alll,a 7/20/64 7.8 44f1 4tl 9 1 6 1 0 207 41 15 0.0 0.2 0.10 248 Alpha . _ 6/20/71 7,3 2,119 22b 13tl Ent '40 Ih9 I1.5 n00 Alhr+a 7/3171 7.2 1,500 11l,,7 87.h 20').2 0 I21.� 417.5 ;1U.1 J2.tl 2,119.7 1,2(11 A ha 8/29"1 7.2 1,100 340.7 77,1 Itl 1.6 e.6 12 n,i L78,6 7I".6 l8.1 1,I IS I,170.9 ,\Ipha 11/98/71 7.3 3,570 184 99.7 217.5 11.4 0 147.7 1.10 b41 Il 7 0.48 2,1J6 1,370 Alpha 12/10/73 3.640 929.1 27 Alpha 20K4 7/Z/7) 7.6 465 52.1 6.1 36.8 - 0 20'.n 47.4 '2.7 0.0 367.8 IS8.1 20K7 7/2/73 7.7 440 48.1 9.2 3 3.3 206.2 52.8 14.0 0 1.6 0.0 364.5 158.1 semi Perched SS/IIW 20K8 2/22/6I 7.7 405 4n 35 1 0 11, 17 1,0 0.5 0.21 262 Alpha�r P<la . 6/!0/61 b.2 411 J4 b 11 1 0 20f 27 14 0.0 1.1 1,07 246 - Alpha�.r B•ta 7/2173 7.67 I50 4i,,5 9.7 14.1 207.4 J7,1 IS.0 0.0 160.9 Alpha ar P.ta 12/20/73 446 12 <01 22 Alpha nr Uela 20K9 2/1161 7.6 415 J4 7 17 .. 0 I"7 t4 I„ U.11 0.6 0.117 .n, Alpha I/tl/bl tl.2 190 IB 11 In U.Un 213 AIph�1 b/2d/64 7.7 410 LR 17 17 2 0 1n2 10 1: 0.0 0.2 0.07 Z40 - .1 vha I/Lh/66 7.1 410 JI tl 15 L 0 1't4 IZ I7 0.0 0.1.

Salt water intrusion is occurring in the Semiperched aquifer as l measured at five test piezometers along the eastern margin of r Huntington Harbour. This situation was anticipated at the time of the marine excavation and was considered to pose no real threat to the underlying fresh waters in the Alpha aquifer. r� 3. Current (1973) mineral quality data from the Alpha aquifer indicate Dthat inland of the Newport-Inglewood fault zone, sea water intrusion is occurring in the aquifer. This intrusion a�'pears to be moving r horizontally inland and not originating from downward percola- tion of overlying saline waters. aquifer wells 20E5,r 4. Chloride ion concentration increases at Alpha a q 20EC and 20Q6 suggest that ground waters exceeding 500 mg/1 chloride ion have moved inland across the Bolsa Fairview fault as depicted on Plate 1. 5. Nitrate concentrations in excess of 1 mg/l, and general odor problems 1 are not associated with the invasion of saline ocean or bay waters. Nitrate concentrations exceeding 10 mg/l in the Semiperched zone have probably originated from the downward percolation of surface waters. 11 6. Considering the present maintenance of excellent mineral quality in rsl ground water at well 201<$, progressive degradation at' the Campbell llll well (20K3) is concluded to be the result of downward peircolation of u waters from the overlying Semiperched aquifer. This migration of r ground water high in chloride and nitrate has probably occurred either at an improperly abandoned oil or water well, or along the casing—of the Campbell well itself. Absolute assurance of this interpretation is precluded, however, because of an absence of monitoring wells seaward of the problem area. --- -------------- -9- 7. Taste and odor problems noted at the Campbell well do not appear 61 to be associated with past liquid waste disposal practices at the Bolsa Chica or Boucher Dump, based upon review of current ground water analyses. • 8. While the Campbell well impairment appears to be a local problem, other nearby wells in the Alpha aquifer could be affected; these specific problems would be identified and differentiated from direct sea water r intrusion by marked increased in nitrate concentration. 9. If future ground water basin operations in the Orange County Coastal Plain are such that water levels at elevations below sea level are sustained in the Alpha and Beta aquifers, remaining shallow wells just inland from the Bolsa-Fairview fault will ultimately exhibit local increases in total mineral concentration from sea water intrusion r� and/or local taste and odor problems. RECOMMENDATIONS Based upon the material described in this letter report, the following recommendations are made: i I. If local water supply conditions on Bolsa Chica Mesa require it, shallow well supplies would be replaced by a few wells constructed in the Main aquifer (500 feet deep), an underlying zone which is not now subject to sea water intrusion. r 2. in consideration of the probability of increased ground water quality problems in the Bolsa Chica area in the future, a periodic well monitoring program should be initiated immediately_. The wells shown in Appendix A should be sampled at least once each six months. Z - 10- 3. Because of the absence of sampling points along portions of the potential intrusion front, additional piezometer nets should be constructed to tap the Semiperched, Alpha and Beta aquifers. A test site for the initial piezometer net should be located just inland from the Bolsa-Fairview fault about midway between wells 20K3 (Campbell) �1 and 20IN12 (BSO-6). J 4. With the present rapid changes in land use',and resultant destruction of shallow wells, it would be desirable to save and maintain if possible, a number of wells with long periods of record for continued monitoring of ground water quality. Selected wells for this purpose are shown in Appendix A. 5. Improper abandonment and destruction of shallow water wells in the Bolsa Chica area can pose hazards to fresh water bearing zones by allowing degraded overlying Semiperched waters to move directly downward to lower fresh water zones. To minimize this potential for impairment, local agenci_ s should be encouraged to specify and enforce complete inter-zonal sealing of shallow wells before they are improperly abandoned or otherwise destroyed. it D U �� -11- I,•hi�� .o�"-`"yL,�,eq, i, n O L,..'• ([f f�J Z•--"..

GITV OF 9-€1J.PaTINZvTON PIE& CH INTER-DEPAH FMENT COMMUNICATION HUNTINGION BEACH To F. A. Elevatorski From Bob R. Allen i I Subject Bolsa Chica Mesa Water Wells Date May 19 , 1977 This is in reference to your request- of May .17 , 1977 for in- vestigation of two water wells owned by Mr. Goodell and located on 1. the Bolsa Chica Mesa immediately southwest of the intersection at Bolsa Chica and Los Patos Avenue. l A field investigation was conducted-, May 18 , 1977 and an exten- sive background follow-up was made. I i According to the documented information we have on hand , it is felt that the subject water wells would have no value to the City ffI Water Department. Following is a list of reasons for the rejection: 1. A study of the area in 1974 by the James M. Montgomery Co. Ye- vealed saline waters had moved inland across the Newport-Inglewood fault zone under the reversed hydraulic gradient. By 1955 saline intrusion had moved inland about 2 , 400 feet, notably Alpha and Beta aquifers. As recorded in the past, we have had this problem with 1 the two City owned wells at Los Patos and Marina View. 2 . Base )on files- c�n4--- -the in he Orange County Water Pollution Department and the California Department of Water_ Resources, waste 7-17uids were discharged at a number of sites on Bolsa Chica Mesa j during the development of coastal oil fields along the Newport- 71 lewood s-truc ura zone ! Perhaps the most conspicuous and well documented disposal site } is the so-called Bolsa Chica Dump or "Boucher_ Dump" , located 1 , 000 feet southeast of Warner Avenue and Bolsa Chica Road. This clump was used to discharge refinery waste , acid sludge and other oil and � . chemical wastes. The presence of these substances in subsurface sediments around the area was verified in 1950 . The odors within the sediments extended north of Warner to degrade the Bolsa Chica a . Community Water Company well . Conclusion 1. The potential for sea water intrusion exists in the Bolsa Chica area. 2 . Salt water intrusion is occurring in the semi-perched aquifer. 3. Nitrate concentration in excess 1 mg/l, and general odor problems . 4 . Wells in the area will ultimately exhibit local increases in total mineral concentration from sea water intrusion and/or local taste and ordor problems. E. A. Elevatorski - memo May 19 , 1977 Page 2 5. Ultimately water from 12 water wells near the dump were to exhibit taste and odor problems. 6. Numerous wells on the Mesa have been abandoned or destroyed in part because of quality problems including taste , odor and salinity . Reconunendation It may be desirable to save the two water wells and maintain them, if possible , as ground water quality monitoring wells . The owner or owners may contact Mr.. James B.

South of Dunbar St . - Huntington Beach , CA Dear Sirs : At your request , • a site investigation was performed on ! the above referenced project . The site is a relative level site with .an slight downward inclination towards the southeast corner , The surface has been ! covered with mounds of dr.eedged material , dumped fill & debris . Just prior to our exploration these surface materials were leveled to facilitate access for the drilling equiptment . The . overall site is rectangular with a 330 foot frontage on Bolsa Chica street and a depth of• 930 feet rectangular section at the southwest corner with a frontage of + 165 and a depth of + 260 feet is not a part of this development . There is a large waste oil sump in the most southerly southeast corner of the property . Some history of--the site indicates that it was used as a borrow pit in the early nineteen forties and the resulting exca - f I . 1 i r W . O . 148901 vations was utilized as a class three dump site for approximately 30 years . The average depth' of the. excavation appears to have been about 30 to 35 feet. PURPOSE AND SCOPE r This investigation has been conducted to evaluate the soil aspects pertinent to the suitability -of this site for the design and construction of multi story residential structures on pile foundations . Grading ;specifications , foundation design criteria , are included in this report as well as an evaluation of the engineering properties of the surficial soils . The engineering geologic & seismic investigation by .Baseline Consultants & The Methane Gas Study by Jack K. Bryant & Associates , Inc . are attached herewith and considered a part of this report . PROPOSED DEVELOPMENT Final plans have not been developed at this time , however , preliminary planning is to place the structures on piles , above grade around the periphery of the site with vehicular access through the center. Utilities would be placed near the property lines . FIELD EXPLORATION The field investigation consisted of a site inspection by our Soils Engineer and the drilling and logging of seventeen ( 17 ) test borings at locations shown on the attached plan of fifty-six ( 56 ) feet below the existing ground levels . Test borings were made with truck mounted rotary and bucket augers . As the holes were advanced , undisturbed samples were obtained and the soils were vi - i� i Page 2 1 14 . 0 . 148901 sually .classified by our Field Engineer. The samples were then sealed and taken to . the laboratory for tes.ting . , FILL CONDITIONS Depths of fill are -tabulated on Table II . NATURAL GROUND Natural ground as encountered in the borings , classifies as SAND , silty , underlain by SAND , fine to medium , in turn under- lain by' CLAY & SAND layers to the depth of, our excavations . The upper portions of the surficial soils are mixed with concrete brick and biodegradable debris . This material provides a cover . for the more volatile hydro carbon waste material below . Ground water was encountered in some of the borings at approximately 50 feet. One boring was left open to 45 feet overnight and water and caving were noted to 20 feet. A summary of ground water and caving is shown on Table III . EXPANSIVE CHARACTERISTICS Expansion tests were performed in accordance with U . B . C . Standard 29-2 . The results as presented in Table V , indicate the surficial soils have a very low to medium potential expansion . CONSOLIDATION Load-consolidation curves for typical soils are shown on Plates A & B. These curves indicate settlement of the pile founda- tions under the anticipated loads should be less than 112 inch , with differential settlement less than 1 /4 inch . SHEAR DATA Direct 'shear tests were performed on typical samples of Page 3 W . O . 148901 soils . Results are presented on Table IV . These shear strength parameters used in the analysis , are based upon tests performed in a saturated state with the rate of deformation of 0 . 05 inches per minute. Each. sample i.s sheared at various confining loads . RECOMMENDATIONS The following recommendations are based on .observations made in the . field , on the results of laboratory tests on samples of the materials - encoun' te.red , on the past experience of this office with similar soil conditions in this general area and on an over- all evaluation of the site conditions . The existing surficial soils should be over excavated and cleansed of debris and replaced as compacted fill in accordance with the accompany "Specifications for Grading " . This over-ex- cavation should be extensive enough to provide a mat 'with a minimum thickness of four (4 ) feet below the buildings and green areas and six (6 ) feet below street and parking areas . It is proposed to cover the existing oil sump with a structual slab supported by piles placed around the periphery . This slab will be utilized as ! a tennis court. The structures should be supported on friction piles uti - lizing the pile capacity values set forth on Plate C . Allowable i lateral bearing support for piles is 300 lbs/sq . ft . per foot of depth . The point of fixity may be assumed at the surface of the fnative material below the trash fill . Page . 4 W . O . 148901 Expansion tests indicate that the surficial soils on the site have a low to medium expansion potential therefore any concrete flat work on grade should be protected by reinforcing with 6x6/6-6 welded wire mesh or equal . No shallow ground water was encountered in the borings and R should not be a factor in the development of the site utilities . Surf.icial caving did not occur 'in the borings and therefore should not effect the installation 'of utility lines . All regulations of the State of California Industrial Safety Commission and the 1970 OSHA requirements , should be observed during all underground work . ! The recommendations of this report are based upon the assump- tion that the soil conditions do not deviate from those disclosed in the borings . If any, variations are encountered during construe- tion or if the proposed construction will differ from that planned at the present time , ACTION ENGINEERING CONSULTANTS should be noti - fied so that supplemental recommendations can be given . This report is issued with the understanding that it is, the responsibility. of the owner, or of his representative , to ensure that the information and recommendations contained herein are called to the attention of the Architects and Engineers for the project and that the necessary steps are taken to see that the Contractors I I and Subcontractors carry out such recommendations in the field . ! The recommendations set forth in the report " Evaluation of Landfill- Gases at the Mola Project Site" by Jack K . . aryant R Associates , Inc . dated October 1978 , are attached hereto should ! be incorporated into design considerations .

The resulting gas pressures were in a range from zero to two-tenths inches of mercury and highly variable. Combustibility was found in only a. few tests and with no apparent consistency. D. Gas samples taken after the second set of tests were analyzed and identified as having a high percentage of carbon dioxide with some methane The proportion of methane to carbon dioxide was considerably lower than that. predicted by the equation describing the theoretical production of methane and carbon dioxide from "the decomposition of organic matter. An nrinr Which was apparent on the site_ryas investig_ated and material thou ht ts) -be the source analyzed. This substance was iden- sed as a resiAu.e_f_rom et'ro eum refining and was found to be high in s u 1 f uu r_ d i o.xi_de RECOMMENDATIONS Recommendations based on this study are: 1 . The present findings indicate that no methane gas control system is warranted. 2. Provisions for. adequate ventilation of the site through open- space below structures and/or open landscaped areas will eff- ectively mitigate any residual gas traces. j � f 3. Appropriate soil treatment to neutralize certain odoriferous materials present on the site is encouraged prior and during construction. INTRODUCTION This report has been prepared at the request of Action Engineering for the purpose of determining the type and nature of gases located at a former landfill site in the 17000 block of Bolsa Chica Boulevard (Figure 1) . This site is proposed for development of an apartment complex similar to those on contiguous properties. Because of the potential for the generation. of methane gas within a landfill , this study was authorized to determine if a potential hazard exists. In order to evaluate the potential risk, tests to determine the pressure and combustibility of on-site soil gases were conducted. Additionally, gas samples were obtained for subsequent laboratory analysis. Due to concerns expressed about odors at,`the site, certain suspect (odoriferous) materials were . also analyzed.

It was .determined that the study would be based on three testing periods , approximately five days apart. Gas samples were taken during the second testing period. Because of the variable effect of atmospheric pressure on low soil pressure readings the atmospheric pressure prior to, during , and following the tests was obtained from the weather service. Equipment The following instruments and equipment will be used in conducting the tests and drawing samples. Bacharach Combustible Gas Indicator (Model G) Gilmont Differential Pressure Manometer (Accurate to .001 inches) . - Tygon Tubing Probes (Figure 2) 1 .5 Liter Stainless Steel Evacuated Cylinders 1 i Probe Implacement i The tests and samples will be taken at ten sample wells located on i the site (Figure 2) . These sample wells are to be drilled by Action Engineering. After the test probes were implaced the well was backfilled and covered by a concrete valve vault with cast iron cover to prevent vandalism. Each well will contain two probes cut from lengths of 4 inch inside diameter tygon tubing. One probe will be placed at a depth of 15 feet and the other at a depth of 25 feet. Each probe is to be made of a ` single length of tubing and taped to identify it as a 15 or 25 foot probe. Each probe will be drilled with four holes every inch and i wrapped with a close woven nylon mesh, securely taped to the ends approximately {{ one foot from the below ground end of the probe. This will prevent the Ii holes clogging with dirt but still allow gas to enter the probe. After the probes are set, and the well backfilled, the probe will be plugged to allow the pressure in the probe to come to equilibrium. Sample and Testing Procedure After the probes are implaced, seven days will be allowed for them to come to equilibrium with the landfill gases. Soil pressure will be tested by a u-tube manometer. The pressure end of the manometer is conn- ected to the probe with plastic tubing and a plastic connector while the other arm of the manometer is open to the atmosphere. The probe is pinched JACK K.

The soil gas pressure will deflect an indicator fluid (specific gravity of 1 .0) from a set point. The set point will Ue re-established and a deflection reading taken. This reading is equivalent to the soil gas pressure in inches of water. A conversion to inches of mercury will be made to equate these readings with the atmospheric pressure. Gas combustibility will be tested by use of a combustibility indi- V cator. This test is conducted after the pressure test to prevent losing gas before the pressure is read. The combustion indicator will be att- ached to the probe in the same manor as the pressure test. The gas will be drawn into the indicator by- use of an aspir'Ator bulb. The reading, as a percent of the lower explosive limit, will be taken directly from the meter. A reading of 1 .0 will indicate a combustible mixture. j Whenever a combustible reading is obtained, a dilution cock on the instrument will be opened for a 10 to 1 air to sample ratio. The test will then be repeated. This allows more accurate measurements of values greater than one. Gas samples , for laboratory analysis will be f drawn immediately after the second test period. Evacuated cylinders will be connected directly to the probe and the shut-off valve opened slightly. The sample is to be drawn over a five minute period. These samples will be taken after the other tests to prevent distortion of results. A piece of "purpleish" material , suspected to be odoriferous , exposed during previous soil work on the site and samples from a tar- like sump, also thought to be an odor source, are to be analysed. An expert in the field of odor control will be consulted, as appropriate, based on the results of the suspect odor causing materials. RESULTS Gas r Due to unseasonal rains between the first and second and the second and third test periods, the original sampling interval became lengthened (Table 1) . Since water in the soil can entrain gases and distort test results, testing had to be delayed until soils at the site had dried. Problems on the site during the testing which may have affected the results were the collapse of sample well number two after probe placement. Consequently, this sample point had to be abandonded. Well number five suffered a partial collaspe prior to implacement of the probes. The backfill in well number four settled approximately eighteen inches. Due to ground water intrusion after the wells were drilled, the 25 foot probes in wells 4 & 5 had to be placed at 17 and 20 feet respectively. The 15' foot probes in these wells were adjusted to extend approximately half the . distance from the surface to the end of the longer probes. JACK K.

Since the manometer used for soil pressure sensing is of the differential pressure type and quite sensitive, air blowing across the open end caused variations in fluid levels. The results of the three test periods are summarized in Table 1 . As noted in Table 1 , water appeared in some probes and in others , operation at the. aspirator bulb was difficult, possibly indicating water or dirt in the probes. �. The subsurface soil pressures were measured with respect to atmos- pheric pressure. Consequently, high atmospheric pressure will make readings appear low while low atmospheric pressure produces the opposite affect. The value above or below which define4 high or -low pressure is 29.92 inches of mercury, considered normal atmospheric pressure at sea level . The following pressures were recorded at the time of the tests. TABLE 2 k Atmospheric.

Because of this, the detection of methane concentrations in landfills is a specific concern. The proportions of this gas found at the site were generally low; the figures are shown in Table 3 below.

The major components are sul- fonated petroelum oil and carbonaceous matter. The odiferous substance was determined to be sulfur dioxide with a tr�. ace of mercaptan. Due to the mixed nature of the material , it was not feasible to determine exact proportions of constituent compounds. The complete laboratory j report is attached herein as Appendix B. DISCUSSIOPi Gas j The most characteristic features of the test results were their ! variability and low level . Gas pressures and methane percentages were lower than would be expected for a Class 1 or Class 2 landfill , indicating a paucity of organic matter at the site, which has been described as a I rubble type landfill . Confirmation of this is in the form of concrete and metal debris encountered during drilling. Typically in gas generated by organic decomposition, mostly an anaerobic process ,, the proportions of methane to carbon dioxide are about equal . The high percentage of carbon dioxide to methane in the samples taken here seem to indicate a greater than normal presence of oxygen. This could indicate the fill is not tightly compacted, possibly explaining the collapse and settlement which effected some of the wells. A combustible gas' indicator was used to detect methane gas. Gas which burns on contact with a hot filiament increases the resistance of the filiament and produces a deflection on a calibrated meter. The meter scale is calibrated in per of the lower explosive limit. The lower explosive limit (L.E.L. ) , recorded in Table 1 , is an index of combustibility. A reading of 1 .0 indicates a combustible mixture. Although readings are proportional in terns of combustibility, they can JACK K. BRYANT & ASSOCIATES, INC. 444 w,!510(:,- HiviI, Sit,II! Too Lund OvarIi cn <.I(M!12 0 (213! 117 not be translated into volumes. In air, methane must be in a proportional range of from 4% to i5% for combustion to occur. If the gas were to migrate to the surface, dilution would occur and the concentration of gas would be expected to be lower than that found at depths as listed in Table 3. The combustibile gas indicator does not differentiate between types of gas. It is possible that combustible gases other than methane are being sensed. The lack of correlation between pressure, combustibility and methane would also tend to support the existence of both uncompacted fill and the presence of other gas, possibly hydrocarbon emissions from the petroleum sludge. No pressure gradient is discernible from the test results. The lack of significant subsurface gas pressure end the variability of the little pressure detected appear to make lateral gas migration unlikely. The- results seem to point more toward the presence of gas pockets, t possibly contained in internal cavities. Odor Because of odiferous material found on the 'site Aeroscopic Engineering was contacted to determine possible mitigation measures . A discussion ! with Mr. Joe Spiszman concluded the feasibility of soil treatment to neutralize odor. One method which was discussed provided for dilution of a suitable chemical neutralizing agent in a water truck and soaking the site prior to and during construction. This would be most effective if a layer of soil was stipped off and application made prior to final grading. Mr. Spiszman felt this treatment would work provided the soil ! was treated below the depth of the lowest foundation member. Properly driven pilings penetrating the treatment zone would not impair the effectiveness of the treatment. i ,ll I ! i i ! JACK K.

The analysis indicates that the materials found on-site are generally within accepted standards. However, the water sample indicated that the selenium content exceeds the current EPA maximum contaminant level (MCL) by nearly 1.29 mg/l (1.3 mg/l vs. 0.01 mg/1) . j I For your use I have attached a list of those persons contacted in the preparation of this preliminary report. I r The California Department of Water Resources conducted water quality analyses from 9/62 through 5/70 on the well subsequently closed in the vicinity of the site. This material is attached for responsible agency review. ' I appreciate the opportunity to review those materials sent to your office by the County of Orange, Division of Environmental Health (letter dated November 3, 1976) and California Regional Water Quality Control Board, Santa Ana Region (letter dates; October 10,. 1979) . I thought it appropriate to comment on these letters in order to provide clarifica- tion and/or direction for subsequent review. A rough draft of the alternative mitigation measures being studied is included. Responsible agency comments and/or input in. this area is V required prior to the preparation of the final report. On October 2, 1979, I discussed the proposed project with Mr. Jim Stahler of the State Department of Health Services. He indicated that the State took soil samples during mid-November and are currently test- ` ing these materials at their Berkeley laboratory. I briefed him on our findings so that they may provide additional analysis in certain areas (i.e. , selenium and PCB's) . Based on my conversation with Mr. Stahler we expect additional subsurface chemical characteristics data from the P State very shortly. JACK K.

CA 90802 2131 437-41-18 ACTION ENGINEERING -- MOLA PROPERTY Hazards Report 1.0 Introduction and Summary 1 . 1 Introduction ThJ.c report was prepared at the request of the City of U..unt- ington Beach to determine if potential health hazards exist on-site as a result of subsurface materials. Within the project boundaries is a former Class III landfill site located in the 17,000 block of Bolsa Chica Bouelvard (Figure 1) . The applicant, Mola Development, proposes the development of 224 condominium units on 12:5 acres. Roughlx 5.0 acres in the northern portion of the site was utilized for . landfill purposes. Approximately 30 units would be located over the old landfill area. Several multiple- family residential developments already exist directly adjacent 'to the project boundaries and/or old landfill site. A previously prepared methane gas study identified ].ow con- centrations of methane gas and acid sludge residues from petroleum refining existing on-site. A subsequent analysis of the acid sludge . material. identified the odor-causing agent as sulfur dioxide. The application of a. neutral base substance (i.e. , lime) was recommended as a general mitigation measure. Additional information on how this measure is to be implemented and its resultant environmental impact was . requested by City staff. Therefore, measures to mitigate the existing odor impact will be discussed in conjunction with measures recommended to mitigate potential health hazards should toxic chemicals be identi- fied on-site. 1 .2 Summary (to be completed) 2.0 Test Methodology Phase I of the sampling program involved a review of available reports assessing subsurface conditions (i.e. , Methane Gas Report, Soils Report, etc.) . The preliminary soils investigation dated October 3, 1978, contained a map showing the location, of 17 on-site borings, as well as a .complete boring log with information on the type of materials found and at which depth they were observed. The Methane Gas Study included pressure and combustibility information on subsurface gases from ten sample well locations. The methane gas data provided- informa- tion as to Elie primary locations of subsurface decomposition. To define . the general boundaries of the landfill, the salient data from the aforementioned reports was plotted on a field survey map. Thereafter, a final field investigation was completed to determine the location of six additional borings (see Figure 2 - Sample Locations) . On the morning of October 9, 1979, a drilling rig (auger/bucket type) was utilized for the purpose of providing subsurface soil and water samples for analysis. i f � -� Lti•a o..•r a I - VICINITY MAP FIGURE 1. i ® 6 ® '4 ® 5 Q U_ S ' U Q ' O CD SAMPLE LOCATIONS CIVIL AND ENVIRONMENTAL ENGINEERING JACK K.

The samples were placed in individual containers and sealed for delivery to Associated Laboratories, Inc, for an .assessment of their chemical composition. From October 10. to November 2, 1979, Associated Laboratories analyzed the contents of the samples taken from the site. Composite samples were made from those taken from the site. On this basis, Asso- ciated Laboratories . tested three composite samples for organic (i.e. , chlorinated hydrocarbons, phenols) and inorganic (i.e. , arsenic, sel- enium, ash, as well as general spectrographic identification) materials. The water sample was specifically tested for arsenic, selenium, and phenols. In addition, a general spectrographic anlaysis was conducted on the water sample after an unfiltered sample was dried and ashed. The results of this analysis are attached. 1 .
