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.

1.2 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

2.0 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 .

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 .

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.

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.

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

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.

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.

HEALTH AND SAFETY PLAN

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

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

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.

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

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
