SOLID WASTE ASSESSMENT TEST PROPOSAL WATERMAN SANITARY LANDFILL PROJECT NO. 240475 1.0 INTRODUCTION 1.1 PURPOSE OF PROPOSAL The California Water Code Section 13273 as amended by Assembly Bill 3525 (Calderon, 1984) , requires that the City of San Bernardino determine whether the Waterman Landfill , which was operated by the City on privately owned property, is leaking hazardous substances that may enter the ground-water system and degrade the quality of ground water. The California Water Resources Control Board (Board) has outlined a Solid Waste Assessment Test (SWAT) which, when performed, will enable the City of San Bernardino to make the required determination and, thereby, comply with the requirements of the Water Code and Title 23, Chapter 3, Subchapter 15 of the California Administrative Code. In order to assist disposal site owners and operators in planning their SWAT tests, the Board has developed a guidance document, entitled "Solid Waste Assessment Test Guidance" (Guidance) . This document states that each disposal site owner and/or operator shall submit to the appropriate Regional Water Quality Control Board a report of the SWAT procedures and results when the test is completed (SWAT Report) . The Guidance document also states that, in order to avoid possibly having to repeat the SWAT, a preliminary test proposal (SWAT Proposal) should be submitted to the Regional Board in order to obtain that Board's concurrence that the proposed test will , in fact, determine if the disposal site is leaking hazardous substances. This document is the SWAT Proposal for a water quality monitoring program and test for the landfill . It has been prepared in strict accordance with the Guidance document. 1 p 1.2 MANAGEMENT OF PROPOSAL EFFORT This proposal was prepared for the City of San Bernardino by IT Corporation under County of San Bernardino Contract No. 87-122. Its preparation was under the general supervision of Manuel P. Moreno, Jr. , Director of Public Services, City of San Bernardino and 0. Max Buchanan, Solid Waste Operations Manager, Environmental Public Works Agency, County of San Bernardino, California. i 1.3 APPROACH In order to develop sound rationale for the design and emplacement of the proposed monitoring network, it was necessary first to acquire and analyze geoscientific and technical data within one mile of the landfill (Site) . The following approach was used: a) a plan was developed which, when implemented and completed, would result in the acquisition, compilation and analysis of all available data pertinent to the development of an understanding of the hydrogeologic regime at the Site; b) a team of scientists and technicians was appointed by IT Corporation to gather the identified data; c) the data were compiled and analyzed, and; d) the proposed monitoring work program was devised. 1.4 SOURCES OF DATA The following sources of information and data were used: • San Bernardino County Environmental Public Works Agency • California Department of Health Services • California Regional Water Quality Control Board • California Department of Water Resources • California Division of Mines and Geology • U.S. Geological Survey 2 • City of San Bernardino Public Works Department • City of San Bernardino Municipal Water Department • City of San Bernardino Planning Department • San Bernardino County Flood Control District • San Bernardino County Environmental Health Services 2.0 INTRODUCTORY DATA The Waterman landfill is located within the City of San Bernardino along the south bank of the Santa Ana River (figure 1). It extends from approximately 800 feet east of Waterman Avenue northeast to the Atchison, Topeka, and Santa Fe Railroad Bridge. Aerial photographs of the site from before (1938) , during (1953), and after (1987) landfill operations have been included as figures 2, 3, and 4. The landfill was operated by the City of San Bernardino from 1950 to 1960 on land leased from the Tri-City Airport, which was owned by Joseph and Evelyn Brier. In addition to its refuse disposal purpose, the landfill was also a means of flood control and a way to reclaim land previously eroded by the flood waters of the Santa Ana River. There was also a private landfill along the south bank of the Santa Ana River adjacent to the City-operated landfill . It was located directly west of the Waterman landfill and extended from the Waterman landfill to Waterman Avenue. It was owned and operated by Joseph Seto and was in operation during at least the late 1940's and 1950' s. The aerial photo from 1938 suggests that there may have been some activities on the site during the 1930' s. The operations and disposal practices of the private landfill are beyond the scope of this report on the Waterman landfill . i 3 2.1 NAME OF SITE The Site is currently known as the Waterman or Tri-City Landfill . 2.2 NAME AND ADDRESS OF OWNER AND OPERATOR The landfill was operated by the City of San Bernardino on a 10-year lease (2/1/1950 to 2/1/1960) from Tri-City Airport. The property on which the landfill is located is currently owned by Rancon Realty Fund IV, which is developing an office complex, Tri-City Corporate Center, adjacent to the site.

It is located on the south bank of the Santa Ana River, approximately 800 feet east of Waterman Avenue in the City of San Bernardino. 2.3.2 Township, Range, and Section The Site is located in Section 23, US, R4W, San Bernardino Baseline and Meridian (S.B.B.M.) . 4 d I 2.3.3 County Assessor's Parcel Number The San Bernardino County Tax Assessor' s parcel numbers of the Site are 281- 341-4,9,10 and 281-021-31. 2.4 USAGE AND CAPACITY 2.4.1 Classification, Types of Waste, and Usage The landfill was operated primarily as a cut and fill operation with refuse being dumped in trenches about 20 feet deep, 75 feet wide and 850 feet long. Once filled, the trenches were covered with dirt and a new trench dug. At least nine of these trenches were filled. In addition, trees and tree trimmings were burned along the bank of the river and the remains buried. By 1959, burning at the site was discontinued, and combustible materials were no longer accepted at the landfill . A record of the material dumped at the landfill was kept by the City for one week in November, 1953. Approximately 900 loads (7,000 yards) were accepted that week with 400 from the City Refuse, Park and Street Departments, 60 from the City of Colton Refuse Department, 56 from the County Road, Hospital , and Housing Departments, 177 from private individuals, 123 from businesses, and 77 from professional tree trimmers. The material was estimated to be 40 percent refuse, 25 percent trees and trimmings, 21 percent rubbish, and 6 percent street sweepings and dirt. Borings drilled on the property have found the landfill material to consist primarily of paper and wood byproducts with lesser amounts of metal , bottles, and rubber products. 2.4.2 Capacity and Quantities of Waste There are approximately 600,000 to 700,000 cubic yards of trash and soil within the landfill . 5 I 2.5 EXISTING PERMITS, ENFORCEMENT ORDERS AND ADMINISTRATIVE LIABILITY COMPLAINTS 2.5.1 Permits The landfill was operated under a permit issued by the Board of Supervisors of San Bernardino County on February 27, 1950. 2.5.2 Existing Enforcement Orders There are no existing enforcement orders for the landfill . 2.5.3 Administrative Civil Liability Complaints There are no administrative civil liability complaints filed against the landfill. I 2.6 CLOSURE DATA The landfill was closed February 1, 1960. Upon closure, the landfill was covered with dirt and leveled. There is no information regarding engineering details of the closure, but see 3.6. 2.7 CLOSURE PLAN There is no closure plan for the landfill. 2.8 PROPOSAL PREPARATION AND CERTIFICATION 2.8.1 Name and Address of Preparer This proposal was prepared by IT Corporation, whose address and telephone number area 6 I 17461 Derian Avenue Irvine, California 92714 (714) 261-6441 2.8.2.

Tahse, Geologist License No. 001552 3.0 SITE INFORMATION 3.1 GENERAL DESCRIPTION The Waterman landfill is made up of two adjoining parts - a square parcel approximately 1,000 feet on a side and, to the northeast, a rectangular portion along the river approximately 1,200 feet by 400 feet (figure 1) . The southern part of the square parcel was the area occupied by the cut and fill trenches (the thickness of the landfill material ranges between 5 and 25 feet), while the northern portion was one large open area with fill material in excess of 20 feet. The northeast parcel also appears to have been one open area with an average thickness of 10 to 15 feet of landfill material . Both parcels have been treated by dynamic compaction (in order to reduce future settling) in preparation of future development as part of the Tri-City Coporate Center. Portions of the old landfill were excavated and removed during the construction of Vanderbilt and Carnegie Drives, so all of the landfill material is now north of these two roads. 8 3.2 ANCILLARY FACILITIES 3.2.1 Buildings The site is an open, graded field. The only things built on the former landfill are a helicopter pad and an adjoining parking lot, both of which are located on the southeastern edge of the landfill . The location of these facilities will be shown in the SWAT report. 3.2.2 Waste Handling Areas Information about waste-handling areas is not available. Old photographs show that the trees and tree trimmings were burned along the bank of the river. 3.2.3 Equipment Handling Areas Information about equipment handling areas is not available. 3.2.4 Roads Access tc the site was an unpaved road from Waterman Avenue that ran along the southern boundary of the landfill . 3.3 CONTAINMENT STRUCTURES The San Bernardino County Flood Control District has constructed a dike, or levee, on the northern edge of the landfill adjacent to the Santa Ana River to prevent flooding and erosion of the river bank and, thus, the landfill . 3.4 PRECIPITATION AND DRAINAGE CONTROL FACILITIES There are no drainage control facilities. Adjoining pieces of property should drain into the newly constructed roads rather than across the landfill site. 9 3.2 ANCILLARY FACILITIES 3.2.1 Buildings The site is an open, graded field.

More recently, additional soil and river sand were placed on the landfill prior to dynamic compaction by Tri-City Corporation. 3.7 LEACHATE COLLECTION AND REMOVAL SYSTEM There is no leachate collection and removal system at the landfill . 3.8 LEAK DETECTION SYSTEM There is no leak detection system at the landfill . 3.9 SEPTAGE RECEIVING AREAS Septic tank liquid waste was not accepted at this landfill . 4.0 SOLID WASTE ASSESSMENT MONITORING PROPOSAL The following paragraphs describe the monitoring system work program that IT Corporation proposes to conduct in order to test whether the landfill is leaking hazardous substances to the groundwater system. The proposal was prepared in accordance with the provisions and requirements of Section III, paragraphs A through G of the Guidance document. 10 I 4.1 HYDROGEOLOGY In order to determine the paths most likely to be taken by landfill leachate and to decide the most effective sample collection locations, it is essential to have an understanding of the geology and hydrogeology of the Site. The following data and discussions have been included in order to provide that understanding. The Waterman landfill is located in the San Bernardino Valley topographic and structural depression, which is bounded on the north by the San Gabriel Mountains, on the east by the San Bernardino Mountains and on the south by a group of irregular hills. The depression is filled with alluvial deposits that range in age from late Tertiary to Recent. According to Dutcher and Garrett (Dutcher and Garrett, 1963) , "large alluvial fans underlie most of the area, but its landforms also include alluvial benches and terraces near the mountains, stream channels, and elongate hills, ridges, and scarps along the trace of the San Jacinto fault, which strikes northwestward across the valley about in the center of the area. This fault and others divide the area into ground-water basins, which include the Bunker Hill , Rialto-Colton, upper and lower Lytle, and Chino basins." The Waterman landfill itself is located in the Bunker Hill basin. The Bunker Hill basin is crossed by the Santa Ana River, which flows generally westward (figures 1 and 6) . 4.1.1 Geomorphology Landforms The site is located in the floodplains of the Santa Ana River and San Timoteo Creek. The topography of the surrounding area is relatively flat. The San Timoteo Badlands are the prominent landform. The Badlands are located slightly more than a mile south of the site. 11 Drainage System The main drainage in the area is provided by the Santa Ana River, with secondary drainage provided by the San Timoteo Wash to the southwest of the landfill and the Mission Drain to the northeast (figure 5) . The natural drainage at the site is to the west with some drainage to the southwest towards Vanderbilt Drive due to recent grading. 4.1.2 Stratigraphy The youngest sediments in the basin consist of Recent alluvium, which occupies the channels beneath the Santa Ana River and its tributaries and through which ground water moves out of the basin to the Rialto-Colton basin. Beneath the Recent, or younger, alluvium are the following sedimentary units: older alluvium of Pliestocene age, the principal water-bearing unit of the area; and continental deposits of Tertiary to Quaternary age (figure 6) . The younger alluvium attains a maximum thickness of about 125 feet beneath the Santa Ana River in the general vicinity of the site. It consists of interbedded sands and clays. The older alluvium ranges in thickness from 700 feet to 1,400 feet. Beneath the site, it is approximately 1,200 feet thick. Figure 7 shows that the post-Tertiary-early Quaternary stratigraphic section, which is the ground-water reservoir, consists of three permeable water-bearing zones, separated from each other and from the younger alluvium above by less permeable zones, which act as confining layers. 4.1.3 Structure There are two right-lateral , strike-slip faults within one mile of the site (Dutcher and Garrett, 1963) [figure 6 and 71 . The San Jacinto Fault, a mile to the southwest, is considered to be one of the most active faults in southern California. The evidence for the fault consists of both surface topographic features and a subsurface barrier blocking westward ground-water movement in the older alluvium across much of the San Bernardino Valley. 12 1 The Loma Linda Fault has been inferred to pass beneath the landfill site (figures 6 and 7). There is evidence for the fault in the bedrock north and south of the San Bernardino Valley, but no topographic evidence in the valley itself. The fault does not act as a barrier to ground-water flow, but there is evidence in some deep water wells of a lack of continuity in the stratigraphy near the fault. Therefore, the fault is believed to have been inactive in Recent time and to be buried below unfaulted sections of younger alluvium and the upper part of older alluvium. 4.1.4 Surface Water The average flow for the Santa Ana River at the E Street gaging station (approximately 1 mile downstream of the site) for the period between 1967 and 1983 was 105 cfs, with an average volume of 76,070 acre-ft/year. These values are artifically high since 1967, due to the discharge of effluent from the sewage treatment plant upstream of the gaging station. By contrast, the average flow was only 12.5 cfs for the period between 1940 and 1954. The maximum flow recorded was 28,000 cfs on February 25, 1969. The landfill was under water during the 1969 flood. The average flow for San Timoteo Creek at Redlands Boulevard (approximately 1 mile upstream of the site) was 3 cfs with an average volume of 2,170 acre- ft/year. The maximum flow was estimated to be 15,000 cfs, also on February 25, 1969. 4.1.5 Ground Water Shallow monitoring wells have recently been drilled on the Tri-City Corporate Center site immediately south of the landfill . These wells show the depth to ground water in the area to range from 13 to 40 feet, with flow in a northwesterly direction toward the river (figure 8 and table 1) . Figure 8 shows the water levels measured on June 2, 1987. Maps for other times during the last year would also be similar, because fluctuations in the wells have 13 f been less than 2 feet. Well #59 is the only exception with a fluctuation of nearly 6 feet. The ground water elevation at well #59 does not fit the elevation contours established by the four other wells, possibly because the ground-water level in that well may be affected by the nearby production wells along the Gage Canal. Additional data will be acquired to help determine the i effect of these production wells. The shallow aquifers within the upper confining layer shown in figure 7, such as the one just described, are separated from the deep confined aquifer by 200 feet of fine-grained sediments, so that many of the water production wells in the area are completed below 500 feet. Historically, depths to ground water have ranged from near surface to approximately 100 feet, due to changes in water usage, precipitation, and, most recently, recharge of the Bunker Hill basin with water imported from northern California. Early in the 1900' s, the Bunker Hill basin was known for its marshes and artesian flow from wells completed in the deep confined aquifer. Ground-water elevation maps show that ground water flows westerly toward the San Jacinto Fault (Dutcher and Garrett, 1963). However, these maps appear not to represent ground water flow in the shallow aquifers beneath the site. 4.1.6 Location of Wells In addition to the wells just described, numerous wells exist within a one mile radius of the landfill (figure 9) . Most of these wells were installed as water supply wells for irrigation and domestic purposes. More information i will be gathered for these wells for the final SWAT report, including their current status, Zones in which they were completed, and current water levels, in order to provide a thorough understanding of the hydrogeology of the area. 14 4.1.7 Climatic Factors Precipitation For the period 1906 to 1986, annual precipitation measured by the Gage Canal Company at a location approximately one mile northeast of the site has ranged from 4.4 inches to 26.8 inches, with an average of 13.2 inches per year (San Bernardino County Flood Control District, File 3273) . Evaporation and Transpiration Pan evaporation rates have been measured at the Riverside Citrus Experimental Station (OWR, 1979) . For the period October, 1925, to September, 1978, evaporation ranged from 2.83 inches for the month of January to 9.88 inches during the month of July. The average yearly evaporation during this period was 71.98 inches. There are no data on the transpiration rate in the vicinity of the Site. 4.2 SCOPE OF WORK AND OBJECTIVES It is evident from the preceding description that several important uncertainties exist in the geologic and hydrogeologic picture. These uncertainties are listed below: • depth, character and permeability of the alluvium • depth to ground water table adjacent to the river • gradient and direction of flow of groundwater • relationship between the young alluvium and river channel deposits • northern extent of landfill material relative to the present river bank 15 In order to eliminate these uncertainties and be able to design an effective water quality monitoring system, the scope of the proposed work program and its objectives are as follows: 1) drill three test holes in order to: • characterize subsurface lithology; • determine the depth to the groundwater table; • determine the groundwater gradient and flow direction. 2) following (1) and based on the findings of (1) , complete two, possibly three, of the holes as upgradient and downgradient monitoring wells. If necessary, drill an optimally located fourth hole and complete as an upgradient or downgradient monitoring well . 3) collect and analyze surface water samples from the Santa Ana River, both upstream from the landfill as well as downstream, to determine if contaminants from the landfill are entering the Santa Ana River; 4) collect and analyze groundwater samples from the final monitoring wells to determine if groundwater has been contaminated by hazardous substances. 4.3 STATEMENT OF WORK The depth to and gradient of the ground-water table, as well as the northern extent of the landfill , are not accurately known. Because it is necessary to determine these in order to be able to locate effective upgradient and downgradient wells, the work program will be conducted in two phases. Phase I I Phase I will determine the depth to and gradient of the groundwater table. It will consist of the drilling and construction of three wells at the locations shown on figure 10 and will include four tasks, as follows: 16 Task Activity I Drilling, sampling and logging of three boreholes, installation of monitoring wells and collection of surface water samples II Sample analyses III Data compilation and analyses IV Preparation of Phase II work program Borehole WA-1 is located south of the landfill and is intended to be an upgradient well . Boreholes WA-2 and WA-3 are located north and northwest of the landfill and are intended to be downgradient wells. These wells will be drilled along the bank of the river beyond the northern extent of the landfill . If landfill material is encountered in the bank of the river, it may be necessary to drill the downgradient wells on the edge of the river channel . Phase II Phase II may include the drilling and construction of a fourth well . This well would be located based upon the results of Phase I . Phase II will consist of four tasks, as follows: Task Activity I Drilling, sampling and logging of fourth hole and construction of monitoring well II Sample analysis III Compilation and analysis of all data IV Preparation of SWAT Report 17 i 4.4 DESCRIPTION OF PROCEDURES 4.4.1 Drilling All drilling will be done with truck-mounted drilling rigs using air as the drilling fluid. By using air, contamination of soil and water samples by drilling mud will be eliminated, and possible sealing of the bore hole sidewalls with drilling mud also will be eliminated. Air used for drilling will be filtered and oil free. An air filter will be installed downstream of the air compressor, and all pipe joints downstream of the air filter will be free of oil and hydrocarbon greases. Fluorocarbon greases will be used where lubrication is required. No foams or other ( substances will be used with the air stream. All boreholes will be 10 inches in diameter, and outside drilling casing will be 10.15 inches outside diameter black steel . Casing will be driven to the drilling face as drilling progresses. This will reduce or eliminate the possibility of hole-caving as well as cross- contamination of water-bearing zones. Drilling casing will be removed from each borehole in which it is used. In order to protect the integrity of the geologic and ground-water samples collected during and subsequent to drilling, the following procedures will be used: • prior to drilling a hole, all boring tools to be used in the hole will be disassembled, then steam-cleaned and washed and rinsed with clean, uncontaminated water of a known quality and from a single source. They will be air-dried, stored on above-ground racks and covered with polyethylene sheeting until used. • prior to being installed, all well-construction material will be disassembled and cleansed of packing substances by steam cleaning and washing and double rinsing with de-ionized water. 18 face or forcing it below hydraulically. The spoon inside diameter will be 3 inches. An appropriate catcher will be used, depending on the type of material being drilled. For each borehole drilled, samples of drill cuttings will be obtained at 1- foot intervals and logged by an experienced geologist. In addition, drilling characteristics, including drill rates and drillers estimates of particle size and formation hardness wil be noted and recorded for 1-foot intervals. For each' borehole, split-spoon samples will be obtained at approximately 2- foot intervals, if the sediments are soft enough and fine enough to allow for split-spoon sampling. Logged information will include as a minimum for each drill-cuttings sample taken particle size, mineralogy, and/or rock type, color, odor, visual estimate of moisture content, drilling rate and other drilling characteristics, such as drill-stem chatter, that may indicate formation hardness and particle size. Logged information will include for each spoon sample taken the same parameters as above, except that drilling characteristics will include blow counts. Selected samples will be tested in the field for moisture content, pH, and electrical conductivity (1:1 soil (or rock) to water suspension) . Moisture will be determined with a Speedy Soil Moisture Tester. This method reacts the water in a sample with calcium carbide, liberating acetylene gas, in a pressure bomb. The increase in pressure is read on a gauge on the pressure bomb, calibrated in percent soil moisture content. pH will be determined by mixing equal weights of water and rock or soil , agitating briefly then allowing the solid material to settle out of suspension. The pH of the supernatant liquid will then be measured. Electrical conductivity will be determined on an aliquot of the supernatant liquid. De-ionized water will be used for pH and EC measurements. 20 4.4.2.3 Ground Water Samples Ground water samples will be taken from the saturated zone during Phase II. In order to obtain representative samples, each well will be purged by removing sufficient well-casing volumes of water before collecting a sample for analysis. The temperature, pH, and specific conductance of each well volume taken will be measured, and a sample will not be collected until these readings become stable. After purging, a water sample will be collected using a Teflon® bailer. 4.4.2.4 Sample Analysis Vadose Zone Soil Samples Soil samples from the vadose zone will be chemically extracted (WET test) and then analyzed for the following chemicals, in accordance with the requirements of the SWAT Guidance: Phosphate Sulphate ICP metals: Sb, As, Ba, Be, Cd, Ca, Cr, Co, Cu, Fe, Pb, Mn, Mo, Ni , K, Ag, Na, Tl , V, and Zn. Hg and Se by atomic absorption spectroscopy Electrical conductivity pH Ground Water IT proposes that at least six ground-water samples be collected: four samples from the proposed upgradient wells (2 from each) and one sample from the proposed downgradient wells. One of the upgradient samples and all the downgradient samples will be analyzed for the following: 21 EPA methods 601 and 602 ICP metals: Sb, As, Ba, Be, Cd, Ca, Cr Co, Cu, Fe, Pb, Mn, Mo, Ni , K. Ag, Na, T1 , V and Zn. Hg and Se by atomic absorption spectroscopy Phosphate Sulphate Chloride Nitrate Electrical conductivity pH TDS COD If unidentified peaks are present with EPA methods 601 and 602, EPA method 624 will be run to identify the peaks. If the above pollutant scan indicates anomalous concentrations of hazardous substances, the remaining three samples from the upgradient well will be analyzed for these substances to both corroborate the anomalies as well as to provide statistical accuracy to final reported results. Except for field determinations of physical characteristics, all analytical determinations will be made by a laboratory certified by the California Department of Health Services. For QA/QC purposes, field and travel blanks will be analyzed. VOA samples will be collected in triplicate to ensure adequate sampl? volume for follow-up verification and identification analyses, if necessary. 22 4.4.2.5 Sample Control The following procedures provide for the identification, preservation, packaging, handling, shipping, and storage of samples obtained in the field, so that all samples can be readily identified and will retain, to the extent possible, their original nature. i I Identification i i Samples will be marked for identification at the time of collection. Marking will be on a tag or label attached to the sample container (jar, bottle, bag, etc.). Sample identification will include: • Project name and number • Unique sample number • Sampling location (e.g. , boring, depth or sampling interval , and field coordinates) • Sample date • Individual performing the sampling • Preservation or conditioning employed. Preparation, Packing and Shipping Samples will be placed in containers compatible with the intended analysis and properly preserved. Polyethylene or glass containers usually are required, and, in most cases, samples must be cooled to about four degrees Centigrade (4 0C). Samples will be placed in ice chests with adequate amount of ice, sealed, addressed, identified, and placarded as appropr?ate. As soon as field personnel have consigned samples to a commercial carrier, they will notify the laboratory by telephone of the shipment. If the samples are transported by field personnel , the estimated time of arrival at the laboratory will be given. Figure 11 will contain the information that will be provided to the laboratory. A blank of this form will be completed at the laboratory during the telephone conversation. 23 Y The final step that will be used to provide information to the laboratory is shown in figure 12. The Request for Analysis form will be completed by the field personnel , or other appropriate project personnel , and included with the chain-of-custody record. The Request for Analysis will be provided so that analytical requirements will be defined and sample holding times will not be exceeded. Chain-of-Custody An essential consideration in obtaining accurate chemical analyses is the ability to demonstrate that the samples were obtained from the locations stated and that they reached the laboratory without alteration. Evidence of collection, shipment, laboratory receipt, and laboratory custody until disposal must be documented to accomplish this. Procedures will be used that accomplish this documentation through a chain-of-custody form that records each sample and the individuals responsible for sample collection, shipment, and receipt. Figure 13 shows the chain-of-custody form that will be used in the collection and shipping of samples. The following procedures will be followed for all samples subject to chemical analysis: • Sample containers will be sealed in the field. Any samples that do not arrive at the laboratory with seals intact will not be considered to have been in valid custody. • A chain-of-custody record will be initiated in the field for every sample. A copy of this record will accompany its sample. • Each time responsibility for custody of the sample changes, the new custodian will sign the record and denote the date. All changes of sample custody will be a person-to-person exchange of custody documents and samples. 24 . p • Upon sample destruction or disposal , the custodian responsible for the disposal will complete the chain- of-custody record, file a copy, and send a copy to the Project Manager or to his designated representative for recordkeeping. • The custody of individual sample containers will be documented by indicating appropriate chain-of-custody information on each sample tag or label for all chemical analysis samples. • The following documentation will supplement the chain- of-custody records: - Field log book ultimately to be filed in the project files - Sample label on each sample - Sample seal on each sample - Field collection report - Photographic records (wherever practical and to the extent economically feasible) . • Prior to sampling, all personnel involved will have received copies of the chain-of-custody procedure and will be instructed in its use. Multipart chain-of-custody forms will be used so that a copy can be returned to the individual shipping the samples after they are received at the laboratory and after disposal . 4.4.3 Borehole Logging An IT geologist will supervise the operations of the drilling rig and perform sample collection and logging of soil and/or rock samples. The logging information recorded in the field will include: Headspace analysis. Selected soil samples will be checked in the field for presence of volatile organics using a volatile organic analyzer, such as an HNu-model pt.,)toionization detector. • Heading information, including project number, boring number, person responsible for logging the hole, ground elevation and coordinates, and date started and completed. 25 • Depth, recorded in feet and tenths of feet. • Detailed soil descriptions, including: - major soil or rock component - secondary components and estimated percentages - unified soil classification - color - consistency or density - moisture content - listed as an adjective (e.g. , dry, moist, wet) - texture - depositional origin. • Depth/elevation interval • Depth/elevation of lithologic changes • Water-table information and method of determination • Sample drive and recovery • Equipment details • Drilling sequence and comments • Problems encountered 4.4.4 Installation of Monitoring Wells Upon completion of Phase I, monitoring wells will be completed in selected boreholes according to the industry standards for monitoring wells for hazardous waste sites. The well design that will be used is shown in figure 14. The wells will be constructed of 6-inch nominal diameter stainless steel well screen and flush-threaded PVC riser pipe. The screened interval will be 30 feet long, with 20 feet of this length below and 10 feet above the ambient static water level . The annular space of she screened interval and 10 feet above it will be packed with #30 silica sand. A 5-foot bentonite pellet plug will be emplaced above the sand pack. From the upper bentonite seal to the surface, the annular space will be grouted with Volclay grout. A one-inch PVC tremie pipe will be used to place all material into the annular space. 26 Each well will extend approximately 3 feet above the ground surface and will be capped with a removable vented cap. Vented steel protective casing (12- inch diameter) equipped with a locking cap will be installed at the time that the cement grout is placed. The casing will be painted safety yellow or orange for visibility and permanently marked with an identification number on the vented cap. A sketch of each monitoring well , showing depth of well , bottom of the boring, screen length and depth interval , coupling location, gravel pack, bentonite seal , grout, cave-ins, location of bedrock, location of ground surface, height of casing above ground surface, and protective casing will be maintained in the project files, along with the original boring logs. The sketch also will include the actual composition of the grout, seals, and gravel pack. 4.4.5 Development of Monitoring Wells The purpose of monitoring well development will be to remove fine materials from the aquifer being monitored and to maximize the specific capacity of the well . Well development will be performed by mechanical surging inside the casing and lifting fine particles by pumping or bailing. A surge block will be lowered into the well above the screened interval . The surging action will start at a low speed and will be gradually increased as the well develops. After surging is completed, the surge block will be removed. A sumbersible pump or bailer will be lowered to remove fines from the well . The pumping or bailing will also increase the gradient and flow of water toward the well . The wells will be developed by alternately surging and pumping or bailing until the pumped water is visibly free of fines or turbidity. The water level data and flow rate of the well development will be noted. These data will give a relative indication of the effectiveness of well development, a preliminary indication of the well performance, and preliminary aquifer parameters, such as hydraulic conductivity, Lpecific capacity, etc. 4.5 HEALTH AND SAFETY PLAN See Appendix A. 27 .'.#of q .: + -a+zc ,,U .' �, 4.6 SCHEDULE Drilling, installation, development and sampling of the proposed monitoring wells and analysis of samples will be done according to the following schedule: Activity Date 1.

Creating a Safer Tomorrow ' Do Not Scale This Drawing APPENDIX A HEALTH AND SAFETY PLAN C APPENDIX A HEALTH AND SAFETY PLAN 1.0 INTRODUCTION It is the policy of IT Corporation to ensure that all of our geotechnical activities are conducted in a manner that is both safe and healthful . Since it is apparent that certain accident and injury risks are unavoidably associated with the proposed soils drilling and sampling work at the Site, efforts will be made to identify, evaluate, and control all potential health and safety hazards that may be encountered by our Site personnel . In order to account for these Site specific control measures, a health and safety plan has been devised for the proposed project work, the contents of which are categorically described in the following discussion. 2.0 HAZARDOUS IDENTIFICATION 2.1 Chemical Hazards Since all of the planned geotechnical activities will be conducted in non- contaminated areas around the periphery of the Site, any chemical contamination, if encountered at all , will be found within the soil and groundwater as dilute components of landfill leachate which has infiltrated the underlying soil in the work area. Although it is possible that some of these leachate constituents may, in fact, consist of hazardous chemicals, the leachate mixture itself is likely to be water soluble, stable, and present in the soil and groundwater in relatively dilute concentrations. The conservative nature of our planned drilling and sampling work in conjunction with these chemical/physical characteristics substantially reduces the possibility that significant chemical exposures will be experienced by our Site personnel . Under these conditions, chemical exposure hazards are almost A-1 exclusively confined to direct skin contact with the contaminated soil and groundwater, a condition which can be controlled through the judicious use of the personal protective controls discussed below. Hydrogen sulfide and methane gas are typically found within municipal landfills as products of anaerobic bacterial digestion, and subterranean pockets of these gases may be encountered during the construction of the monitoring wells. If allowed to accumulate at high concentrations in confined spaces, methane gas can form an explosive mixture with air. Hydrogen sulfide, on the other hand, presents a severe respiratory hazard when inhaled at high concentrations. Because of the large volumes of air that will be introduced into the boreholes by the air drilling equipment, these gases, should they be present at all , will be diluted to safe concentrations before they escape into the work area. Periodic air sampling of the jobsite will be conducted with a combustible gas indicator and hydrogen sulfide detector to verify these safe ambient air levels. 2.2 Physical Hazards In addition to the aforementioned chemical hazards, several physical hazards, which are normally associated with the operation of the air drilling equipment, can be expected to exist at the jobsite. This drilling machinery, for example, is extremely noisy in its operation and can project potentially harmful levels of noise into the surrounding work area. Also, the cyclone soil collection system used to entrain soil cuttings from the air column generates dust which, likewise, can contaminate the ambient air. 2.3 Hazard Survey In an effort to identify other hazards that may be present at the jobsite, our site supervisor will conduct a health and safety survey of the work area before the start of each shift. The results of this evaluation will be communicated to our work crews through a "tailgate safety" meeting in which A-2 all assembled employees are formally presented with the survey findings and are, in turn, encouraged to contribute their own observations on hazards i present and appropriate work controls. A tailgate safety form will be used to document these sessions. 3.0 HAZARD EVALUATION AND CONTROLS The ambient air within the ,jobsite will be periodically tested with a combustible gas indicator in order to assess the fire and explosion hazard posed by the methane gas. Measured combustible gas concentrations that exceed 10% of the instrument's calibrated lower explosive limit will result in the suspension of all work activities until the gas levels can be safely reduced. Hydrogen sulfide gas concentrations will also be measured periodically with a direct reading Draeger Tube air sampling kit. If hydrogen sulfide levels in excess of 10 ppm are detected, then mechanically induced dilution ventilation or air-supplied respiratory equipment will be used to eliminate harmful inhalation exposures. 4.0 PERSONAL PROTECTIVE CONTROLS In conjunction with the environmental control discussed above, personal protective equipment will be used by our personnel during certain phases of the work. The selection of appropriate protective equipment will be based on the type and degree of exposure hazard present and the nature of work activity i assigned to our Site personnel . In general , the following protective clothing will be worn by all Site personnel who must handle or contact contaminated soil or water in the course of their work: 1. Polyethylene coated Tyvek coveralls 2. Hard hat and safety glasses 3. PVC boots and gloves A-3 Since it will not be possible to attenuate the high noise output of the drilling equipment, all crewmen working around the drill rig will be required to wear hearing protection. And, also, if it is apparent that a nuisance airborne dust hazard is a problem in the work area, disposable paper dust respirators (3M #8710 brand) will be worn. The selection of appropriate protective equipment will be made by IT Corporation's resident industrial hygienist. And all personnel who must wear this equipment will be instructed in its proper use. 5.0 CONCLUSION The hazard evaluation and control strategies discussed in this plan are intended to control the accident and injury risks associated with this drilling project in order to ensure that all work can be conducted in a safe and healthful manner. IT Corporation will make available its health and safety staff to support our geotechnical activities at the Site and institute other control measures that may become appropriate as work progresses. A-4 STATE OF CALIFORNIA GEORGE DEUKMEJIAN.Gove ,n CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD SANTA ANA REGION 6809 INDIANA AVENUE, SUITE 200 RIVERSIDE, CALIFORNIA 92506 PHONE:(714)782-4130 °•,,.,.•' October 30, 1987 1 Mr. Manuel P. Moreno, Jr. City of San Bernardino Department of Public Works 300 N. "D" Street San Bernardino, CA 92418 SOLID WASTE ASSESSMENT TEST (SWAT) PROPOSAL APPROVAL - WATERMAN SANITARY LANDFILL Dear Mr. Moreno: We have reviewed your June 30, 1987, Solid Waste Assessment Test (SWAT) proposal. Contigent upon your confirmation of and com- pliance with the following comments, the SWAT proposal is approved. 1. From telephone conversations with representatives from IT Corporation, we understand the northern boundary of the Waterman Landfill may not be clearly defined or understood. We request that you determine the site boundaries for this landfill through the use of appropriate exploration techniques. 2 . We understand from your SWAT proposal that shallow monitoring wells were recently installed south of the landfill site and that there are a number of monitoring wells within a one-mile perimeter of the landfill. We request that the SWAT Report include boring logs and well specifications for the most recently installed wells. Also, SWAT requirements specify that representative background water quality samples be collected from ground and surface water within a one-mile perimeter of the landfill. Appropriate monitoring wells should be selected for sampling and all the water samples collected for the SWAT Report must be analyzed for the same constituents, as described in the Ground Water Sample Analysis Section 4 .4 . 2 . 4 of your SWAT proposal. 3 . The information provided in the proposal indicates there may be no vadose zone underlying the site. If this is the case, the SWAT requirement for vadose zone monitoring is waived. If, however, vadose zone soil samples are collected as outlined in your proposal, EPA Methods 8010 and 8020 should be included in their analysis. 4. Drill-cutting samples must be analyzed every five feet for volatile leachate constituents with a Photo Ionizaton Detec- I Mr. Manual P. Moreno -2- October 30, 1987 tion (PID) or a Flame Ionization Detecion (FID) instrument. That sample containing the highest PID/FID reading must be analyzed in the laboratory using EPA Method 8240. 5. A letter from Pacific Development Company to the Water Quality Control Board dated December 16, 1985, proposed the installation of seven leachate monitoring wells at the landfill site. We request that the current status of these monitoring wells be provided in the SWAT Report along with any historical and current analyses of the leachate encountered. 6. We suggest that you investigate the status of the old under- ground fuel tanks at the now closed Tri-City Airport. These tanks could possibly affect the water quality upgradient of the landfill area. 7. The work proposed in this SWAT proposal appears adequate to comply with the SWAT requirements. We will be better able to determine from the results of the ground water analyses submitted with the SWAT Report whether the requirements for Subchapter 15 have been fulfilled. Please confirm your intent to comply with these comments prior to beginning field work at the site. If you have any questions, please call Mark Adelson or Celia Fitzgerald of our Subchapter 15/Landfill Section. Sincerely, Dixie B. Lass, Acting Chief Subchapter 15/Landfill Section cc: IT Corporation, Irvine, CA Jim Parsons-State Water Resources Control Board-Division of Water Quality CCF:ccf
