Dear Mr. Bornholm:
Re: Tadeo-Hughes -Project Operations Plan
On behalf of the Jadco-Hughes Steering Committee, please find enclosed a copy of
the Project Operations Plan (P.O.P.) for the Jadco-Hughes Rl/FS. Pursuant to the
Consent Order and Rl/FS Work Plan, the POP requires endorsement by USEP A
prior to proceeding with the Rl/FS.
The POP provides details of the concepts presented in the Rl/FS Work Plan. In
working out the details, we have made seven minor additions
modifications/clarifications to the V\lork Plan which are in keeping with the study
objectives and allow a more efficient implementation of the work. These are:
(1)
(2)
(3)
10% of all analyses will be documented by CLP protocols and the balance of
the analyses by SW-846 protocols (see Submittal B, Section B.8). This
procedure will provide valid results verified by CLP procedure and will
permit expedited laboratory turnaround.
A permanent well casing for bedrock wells will be used instead of a temporary
casing (see Submittal A, Section A.4.3). This procedure improves the integrity
of the well seal.
Borehole locations (B-11 and B-12) have been converted to test pits (TP-11 and
TP-12, respectively) (see Submittal A, Section A.4.3). This change allows a
more visual investigation of the two pits which were previously used during
the 1977-1978 Site cleanup for holding drum sludges and liquids.

TP-8 has been moved to investigate a potential fill and debris area identified
in previous investigations (see Submittal A, Section A.4.2).
Two additional soil borings (BH-4 and BH-5), have been added to investigate
subsurface soils in the area of dark-toned material and standing liquids
identified in the 1975 aerial photograph (see Submittal A, Section A.4.3).
Several surface water and sediment sampling locations are rescheduled to
occur in Phase II rather than Phase I. This change permits the evaluation. of
stream data on key points prior to a detailed stream evaluation (see
Submittal A, Section A.4.4).
Soil samples will be collected from boreholes for chemical analysis, above the
water table only. Analytical data from soil samples collected below the water
table are not required since a groundwater investigation is proposed (see
Submittal A, Section A.4.3.2).
Should you have any questions, please do not he~itate to contact us.

Submittal A presents the Site Investigation
Plan (SIP) for the first phase of the Remedial Investigation
at the Jadco-Hughes Site (Site) located in Gaston County,
North Carolina as shown on Figure A.l. The SIP details the
procedures and protocols for implementing the tasks that will
be completed during this phase of the remedial investigation.
The tasks to be completed follow those outlined in the
"Jadco-Hughes Site-Remedial Investigation and Feasibility
Study-Revised Final Work Plan'', (RI/FS Work Plan) prepared by
Golder Associates for the Jadco-Hughes Steering Committee,
dated March 1988. Where differences exist between the SIP
and the RI/FS Work Plan, the proposed modifications are
identified and the rationale for each of the proposed
modifications is presented.
The procedures and protocols presented herein
were developed with guidance from the United States·
Environmental Protection Agency (DSEPA) Region IV Standard
Operating Procedures and Quality Assurance Manual (SOP). The
SOP shall be used as the reference document in the event of
omissions from the RI/FS Work Plan or the SIP.
The Phase I SIP addresses only those tasks
identified in the RI/FS Work Plan as Phase I field
activities, Subsequent field phases ofc1!HJ:l_e_;r~~\U.~\:l_,-i,~ks & ASSOCIATES

A.2 REVIEW OF BACKGROUND INFORMATION
A.2.1 SITE HISTORY
Revision No: 0
Date: 05/31/88
Page: 3
The Jadco-Hughes Site located in Gaston.
County, North Carolina, derives its name from the two
previous operators of the former industrial facilities. The
Site was operated from 1971 to May 1, 1975 as a solvent
reclamation and chemical waste storage facility by C.A,
Hughes Inc. The facilities were subsequently leased to Jadco
Inc. who operated the Site facilities until operations were
suspended and eventually terminated by a Temporary
Restraining Order (dated August 14, 1975) and a Judgement
(dated September 19, 1975) registered by the State of North
Carolina (State), Although the Site operational history is
only traceable to 1971, historical aerial photographs show
the Sit.e was cleared and used for the open storage of
materials by February 12, 1968 (USEPA, December 1985).
Both operators of the Site were in the
business of reclaiming spent solvents for resale using an
on-Site distillation apparatus. In addition, the facility
was used for the open storage of drummed materials consisting
of numerous waste chemicals and chemical waste sludges.
Substantial quantities of sludge were reported to be
generated as distillation bottoms which were stored on Site.

Records from State files indicate that an estimated
8,000 to 10,000 55-gallon drums had accumulated by 1975 prior
to Jadco leasing the facility. The drums were stacked at
various locations on Site and were in various stages of
deterioration. Records indicate that drums were stacked two
and three high in areas; numerous drums wer·e rusted and
leaking and drums were left uncovered resulting in spillages
and overflows during rainstorms. In addition, liquids were
temporarily stored in bulk storage tanks and various areas on
Site may have been used for burying debris. The location of
Site facilities and features during the operating period
which were identified from historical aerial photographs are
shown on the site features map, (Plan A.l).
The types and quantities of chemical wastes
and chemical sludges handled or stored on Site is not fully
documented. However, a State internal memorandum concerning
the permitting of an on-Site incinerator (North Carolina
Division of Environmental Management. September 17, 1974)
indicates that the following chemicals or chemical classes
were present on Site: xylene, toluene, acetone, hexane,
methanol, ethanol, isopropyl alcohol, methyl ethyl ketone,
heptane, alcohol ethers, petroleum ethers, oil, hydrocarbon
fuels, lacquers, lacquer thinners, hydraulic fluids,
solvents, paint removers and thinners, "cleaning solutions",
water and oil mixtures, water soluble coolants, paints, paint

byproducts, greases, and vegetable oils. In add it ion, a
report of a drum washout incident (North Carolina Department.
of Natural and Economic Resources. July 15, 1975) indicated
that the following substances were present on Site: paint
wash; ink wash containing ethyl alcohol, methyl ethyl ketone,
isopropyl alcohol, ethyl acetate, varsol; chlorinated
solvents; acetone; benzene; phenol and derivatives; ethylene
glycol; oils and various lubricants; soluble and insoluble
glue waste; alcohols-ethyl, methyl, isopropyl, isobutyl;
waste paint and resins; varnishes; and various finishes. The
files also indicate that 500 pounds of magnesium were stored
on-Site.
State files indicate that there were various
complaints by residents concerning malodorous air emissions
from the facility and chemical odors downstream of the Site
from the stream which passes under the Site within a culvert
and is referred to as Tributary B. The more severe water
quality violations which were documented and included in the
State complaint in 1975 included the following:
i ) A 50 gpm pump was unattended for two to five minutes
and discharged allyl ·ether into Tributary B. This
resulted in the evacuation of 30 families downstream of
the Site and a temporary closing of the town of
Belmont's water supply on August 9, 1973.

the facility closed and the stored drums and chemicals
removed. Remedial activities were initiated following the
September 19, 1975 Judgement issued in favor of the State
against the previous operators of the Site.
Remedial and investigative activities
continued through 1983 until the requirements of the 1975
mandated cleanup were deemed complete by order in the General
Court of Justice, Gaston County, on October 12, 1983. Prior
to this date, the a USEPA Contractor became involved with the
Site during the remedial and investigative period.
Subsequently, the Site was evaluated by USEPA on June 22,
1984 according to the Hazard Ranking System (HRS) and placed
on the National Priorities List (NPL) after a HRS migration
score of 42.00 was calculated (IT Corporation,
November 1985).
The Jadco-Hughes Site is currently the
subject of an RI/FS under the terms of the Administrative
Order on Consent, dated September 30, 1986 which was signed
by USEPA and the group of identified potentially responsible
parties (PRPs) forming the Jadco-Hughes Steering Committee.
A.2.2 REMEDIAL AND INVESTIGATIVE HISTORY
The history of the investigative and remedial
activities at the Site can be divided into three distinct
periods. These include:

the period ·of investigative activity during the active
operating life of the facility;
the period of investigation during the implementation
of the State ordered cleanup; and
iii) the investigative period following the completion of
the State ordered cleanup.
Detailed chronologic accounts of the
investigative and remedial activities to date are contained
in the RI/FS Work Plan and the "Interim Report-Jadco Hughes
Site-Forward Planning Study'' by Camp Dresser and McKee, dated
May 20, 1985. A detailed compilation and evaluation of the
analytical data generated to date has been completed by
Golder Associates for the Jadco-Hughes Steering Committee
(Golder Associates, January 1987). The following subsections
summarize CRA's review of the contents of these reports and
additional information gathered from the available files as
they relate to this remedial investigation.
A.2.2.1 Period of Active Operation

Natural and Economic Resources and Division of Health
Services during the active processing period of the facility.
These efforts were in response to reported discharges or
complaints and were directed towards documenting water
quality violations by the operators.
The available chemical data from this period
are specific to effluents and spills which occurred at Site
and are of limited use for the purpose of Site
characterization. Analyses of water samples collected during
this period indicated elevated levels of various metals in
the discharges from Site and determined phenols to be present
in the discharges from the June 27, 1974 incident. Analyses
conducted during this period appeared to concentrate on
regulated water quality parameters and did not characterize
any organic compounds which may have been present.
Correspondence files from investigations
conducted during this period did not provide a detailed
account of the chemical usage and inventory at the Site other
than that mentioned in Section A.2.1. St ate reports
documenting site inspect ions, however, indicated that areas
of potential residual contamination included:
i ) the area underlying the bulk liquid storage tanks due
to spillage;

the area of the distillation apparatus which was
reported to be in poor mechanical condition and
leaking. In addition, the reports cited practices
such as the emptyin•g of process vessels onto the
ground during maintenance;
the bulk liquid transfer area between the control
buildings and the bulk liquid storage tanks due to
spillage;
the ditch abutting the process area which received
runoff and pumped discharges;
Tributary B downstream of the process area;
drum disposal areas at the south end of the Site; and
drum storage areas concentrated on the north portion
and the southeast corner of the Site.
A solvent incinerator was also shown located
either in or near the control buildings based on a sketch
from a report dated June 27, 1974. The actual operation of
the incinerator was not well documented although the list of
chemicals in the permit application indicated the substances
were potentially incinerated. Regulatory information
regarding the incinerator was not available in the files

A.2.2.2 Period of State Ordered Cleanup
Revision No: 0
Date: 05/31/88
Page: 11
Cleanup operations were initiated by
C.A. Hughes, Inc. and Jadco Inc. pursuant to the Judgment
issued in September 1975. The removal of drums from Site
continued through 1976, 1977 and was completed by early 1978.
Drum counts taken during this cleanup indicated approximately
13311, 11123, 7431, and 500 drums remaining at Site on
April 5, 1976, on August 3, 1976, on July 8, 1977, and on
Sept ember 26, 1977, respectively. The available files did
not indicate if the drum contents were characterized prior to
removal from Site or if such documentation is available.
Two waste holding pits were constructed and
used in 1977 for an indeterminate period of time to contain
chemicals and sludges from deteriorated drums. The size of
the pit in the south area of the Site was reported as
approximately 20 feet by 8 feet by an unknown depth, while
the size of the pit in the north area was approximately
6 feet by 12 feet by ·an unknown depth (North Carolina
Department of Natural and Economic Resources; January 7,
1977). Both pits were reported to be partially lined with
polyethylene and used for decanting chemicals from the drum
contents emptied into the pits. The use of the pits was
discontinued following a regulatory inspection in 1977. The
pits were subsequently limed and backfilled. However, the

record is unclear as to whether the contained sludges were
removed or left in place.
Water and soil samples were collected by the
Groundwater Section of the North Carolina Division of
Environmental Management during cleanup operations in
September 1977 (Camp Dresser and McKee, May 20, 1985). Soil
samples were taken from three hand-augered holes and water
samples from the spring and one of the augered holes._. Soil
samples were mixed with equal amounts of deionized water and
the resulting extracts were analyzed, Analyses for COD on
the water and extracts indicated concentrations of 220 mg/L
COD for the extract from a 4-foot deep soil sample at one
hole and 300 mg/Land 55 mg/L for extracts from the 3-foot
and 8-foot depths, respectively, at a second hole. The
bailed water from the second hole contained 18 mg/L of COD.
The locations of these auger holes could not be determined
from the tiles to aid in directing the present Site
investigation.
An on-Site landfill was approved and
constructed during the summer of 1978 to contain contaminated
earth and debris (North Carolina Division of Health Services,
September 13, 1978). The landfill was proposed to be placed
six feet above the water table and covered with two feet of
soil. The actual size and horizontal and vertical limits of
the landf i 11 were not available from a ,r.ev.LewGof,0t,he5 ti les .. CIATES

Similarly, the volume and nature of the waste materials
contained is not known. Records indicate only that earth and
debris known to be contaminated were remo~ed from the north
and south portions of the Site for placement in the landfill.
Spoil from the excavated trench landfill was apparently
spread over the southern port ion of the Site·. Alt hough the
landfill was only approved for earth and debris, other
materials may have been placed in it as indicated by holes
observed in the landfill area during a recent Site inspection
by CRA. The observed holes may have resulted from the
subsidence of loose buried debris or potentially from the
collapse of buried containers.
The bulk storage tanks and a mobile tanker
were left at Site following the drum cleanup and landfilling
operations. Sludge samples were collected at various times
from 1978 to 1982 from the tanks to determine their
characteristics for disposal purposes. Hazardous
constituents in the sludge which were quantitated or
tentatively identified in 1981 included: lead, toluene,
xylene, methyl ethyl ketone, naphthalene, phenol,
2-chlorophenol, and chromium (North Carolina Division of
Health Services, November 3, 1981). Analyses of additional
samples of the sludges collected in 1982 reported
quantifiable leve1·s of PCBs. The tanks and their contents
were subsequently removed during the summer of 1983. This
cleanup included the removal of 11 drums of unknown content

building by Triangle Resources Industries.
Prior to the 1983 removal and cleanup
activities, various studies were conducted by USEPA and its
contractors. An air study conducted in May of 1983 found
levels of toluene and methyl ethyl ketone at 110 ug/m3 and
100 ug/m3, respectively, at a location north of the storage
tanks. Based on this study, USEPA determined that ambient
air emissions at the Site did not constitute a hazard. A
sampling program was conducted by NUS Corporation (NUS) in
March 1983, however, the results were considered suspect and
were invalidated (Camp Dresser and McKee, May 20, 1985).
These data were not provided in the review files.
A.2.2.3 Period Following Cleanup
Various field studies were conducted at Site
following the 1983 removal and cleanup activities. Surface
water and sediment studies were conducted by NUS in August of
1983 and by Camp Dresser and McKee in August, 1985. These
investigations primarily concentrated on characterizing
surface water discharges from the Site and sediments located
in the discharge pathways. Analytical results from the two
investigations (NUS Corporation, July 10, 1.984; Camp Dresser (.;ONE:; r l)t,~-Fiu V t:oiS' & A::0::0(./1,IA TES

and McKee, January 21, 1986) identified a range of USEPA
priority pollutant organics at low concentrations in the
surface water and at elevated concentrations in the
sediments. Three soil samples collected during the 1983
program were reported to contain significant levels of
methylene chloride and toluene. The two auger hole samples
contained methylene chloride at concentrations of 640 mg/kg
and 1600 mg/kg, and toluene at 550 mg/kg and 610 mg/kg. A
composite soil sample taken over the southern portion of the
Site was reported to contain toluene at 2,500 mg/kg. The
1985 investigation reported significant levels of PCBs in
sediments on and off Site.
Residential wells were sampled by NUS in 1983
as part of its investigative program and in September of 1985
by the North Carolina Division of Health Services. The
analytical results were reported to indicate the absence of
groundwater contamination in well water. Details of the well
screen depths and supply aquifers, however, were not provided
in the files.
A geophysical survey was conducted in
September of 1985 and a fracture trace analysis and aerial
photography site feature analysis was conducted in December
of 1985 (Camp Dresser and McKee, May 20, 1985; USEPA,
December 1985). These analyses were used in the development
of the present site investigation. CONESTOGA-ROVERS & ASSOCIATES

A.2.3 SITE DESCRIPTION
Revision No: 0
Date: 05/31/88
Page: 16
The following Site description is based on
reports by NUS Corporation and Camp, Dresser and McKee Inc.
Their descriptions of the Site have been paraphrased in the
following subsections.
A.2.3.1 Site Location and Features
The Jadco-Hughes Site is located in Gaston
County, North Carolina as shown on Figure A.l. The Site is
situated between the communities of North Belmont and Catawba
Heights on the east side of Cason Street (S.R.2035). The
six-acre Site is approximately one-quarter mile south of the
intersection of SR 2035 and SR 2036 and 15 miles west of
Charlotte, North Carolina.
The Site is located in a narrow stream valley
with ground.elevations ranging from approximately 619 feet
(MSL) at the southern end to 587 feet (MSL) at the northern
end of the Site. The adjoining communities of North Belmont
and Catawba Heights are situated above the Site at an
approximate elevation of 730 feet (MSL). Surficial drainage
from the Site flows to Fites Creek via an unnamed tributary
and ultimately dra:i!ns to the Catawba River which is at an
elevation of about 580 feet. The raw water SUP.P.lY. intake for CONl:SlOulHlvVEH:S & AtiSU\;IATES

the town of Belmont on the Catawba River is located
approximately 2.7 miles downstream of the confluence with
Fites Creek and approximately 4.7 miles downstream of the
Site.
The Site is located at the confluence of two
small tributaries to Fites Creek. As shown on Plan A.2, one
of the tributaries (referred to as Tributary A) flows along
the north Site boundary. The other tributary (referred to as
Tribut·ary B) originates to the south and upgradient of the
Site. Tributary B passes through the southern portion of the
Site within a concrete culvert, then flows overland along the
eastern Site boundary to its confluence with Tributary A.
Water discharges from a perennial spring located to the east
of the former process area. The water, which flows out of a
box structure, drains into Tributary B. Although past
records indicate the spring flow went around the process
area, at present the water flows over the process area to
Tributary B.
The only visible features remaining from the
former operations are shown on Plan A.2. These include the
concrete floor slabs for the control buildings, the concrete
pads which were presumably used for the loading of drums
during the drum cleanup, the on-Site landfill which is
indicated by the topographic relief, metallic debris adjacent
to the landfill, disposed rubble, exposed drums at the south

end of the Site, and the former Site fence. Although the
Site has revegetated, there are areas where vegetation
appears stressed. The present site conditions which were
reported in Section 2.6 of the RI/FS Work Plan were confirmed
by CRA during a site visit conducted on May 11, 1988.
A.2.3.2 Physiography and Climate
The Site is situated within the upland
section of the Piedmont physiographic province which is an
uplifted surface which generally slopes south or southeast
(Golder Associates, March 1988). The topography is primarily
rolling uplands interrupted by occasional monadnock hills and
ridges which rise as much as 1,600 feet above the surrounding
uplands.
The local climate is mild with average
monthly temperatures ranging from a low of 4l.7°F in January
to a high of 78.7°F as recorded at Gastonia which is
approximately seven miles southwest of the Site. The average
annual precipitation is about 47 inches with March being the
wettest month at an average rainfall of 5.2 inches. The fall
months are generally drier with October being the driest
month at about 2.8 inches of rainfall (Camp, Dresser & McKee.
May 20, 1985).

A.2.3.3 Geology and Hydrogeology
Revision No: O
Date: 05/31/88
Page: 19
The geology and hydrogeology at the Site has
not been characterized or well defined using subsurface
investigations to date.
Lithologic logs were reported for three hand
auger holes drilled by the North Carolina Division of
Environmental Management (Groundwater Section) in
September 1977. Two holes were located in the northeast
corner of the Site and the third in the southwest portion of
the Site. The first five feet of saprolitic material
encountered at all three holes was classified as sandy clay.
The minerals encountered in this layer were reported as being
chiefly quartz, mica, and feldspar. Below this layer to a
depth of about nine feet where the augering was terminated,
the material was classified as a sandy silt. Weathered rock
fragments which were encountered at depths of six to nine
feet were reported to be dioritic. Groundwater was found at
a 6-foot depth in one of the holes in September and at a
4.4-foot depth in October of 1977 (Camp, Dresser and McKee.
May 20, 1985). Th is investigation was conducted prior to the
initiation of remediation activities which may subsequently
have altered the Site surface.
Literature reviews which have been conducted
to date (Golder Associates, March 1988; CamP. Dresser and

1985) indicate that the Site is underlain by
ancient igneous and metamorphic rocks characterized by
composite rock structures in which diorite and granite appear
as intermingled bodies. Golders reported the bedrock in the
vicinity of the site to be a mixed granite/diorite underlying
a weathered and disintegrated rock zone (saprolite) of
undetermined thickness which, in turn, appears to be covered
with alluvial soils washed into the valley from the adjoining
hills.
The Site is believed to be in a groundwater
discharge zone. This belief is supported by the perennial
spring on Site and the presence of dead-ended streambeds
which appear to be intermittent springs. The presence of
intermittent springs may also indicate a fair degree of
fracture interconnectivity with upland recharge zones.

OBJECTIVES
The goal of the Remedial Investigation is to
characterize the nature and extent of residual contamination
present at the Jadco-Hughes Site.
The information compiled during the Phase I
investigation will be used to determine the scope of
subsequent phases of the remedial investigation, if any, and
to conduct a Risk Assessment. Potential remedial
alternatives for the Site will be evaluated, to the extent
possible, with the Phase I data.
The specific objectives of the Remedial
Investigation are:
i) to determine the nature and extent of residual
contamination· attributable to past Site activities of
Site soils overlying bedrock;
ii) to characterize the subsurface geologic conditions;
iii) to characterize the Site hydrogeologic conditions
including horizontal and vertical groundwater flow
directions and velocities;

SITE INVESTIGATION PLAN AND FIELD PROTOCOLS
A. 4. 1 GENERAL
The Phase I SIP has been designed to provide
a sufficiently complete characterization of the Site to
permit an evaluation of the risk posed to public health and
welfare and the environment from hazardous substances
attributable to the Site; an assessment of remedial
alternatives that can effectively mitigate any unacceptable
risks so identified; and an evaluation of additional data
collection requirements. The SIP follows the RI/FS Work Plan
and the tasks/protocols presented herein are modified only
where the review of the available files by CRA indicates that
such modifications are appropriate.
The following field activities will be
conducted during the Phase I investigation:
i) excavation of test pits;
ii) installation of groundwater monitoring wells;
iii) collection of hydrogeologic data and groundwater
samples from installed monitoring wells;

collection of soil and bedrock samples during the
installation of monitoring wells and from additional
soil borings; and
collection of surface water and sediment samples.
The USEPA coordinator and affected property
owners will be notified not less than 72 hours in advance of
commencing field activities.
The following subsections detail the field
activities associated with each of the above tasks. Details
of the chain-of-custody procedures that will be implemented
in the field and a summary of the sampling program are
presented in Section A.6 and Section A.5, respectively.
A.4.2 TEST PIT EXCAVATIONS
A.4.2.1 Purpose/Scope
Test pits will be excavated to investigate
known and potential sources of hazardous substances on Site
and areas which may contain residual contamination from
previous operations. The test pit program will:

characterize materials placed in the on-Site
landfill;
determine the cause of previously identified
geophysical anomolies;
determine if containerized materials are buried in
potential disposal areas; and
characterize subsurface conditions in areas which have
a high probability of demonstrating residual soil
contamination.
A total of 10 to 12 test pits will be
excavated in the locations shown on Plan A.3 (designated by
TP-#). The rationale for the test pit locations are as
follows:
TP-1 is to confirm the presence or absence of buried drums
in an area reported as a potential dispo'sal area in the
southwest corner of the Site.
TP-2 and TP-3 are for delineating the limits of the landfill
and for obtaining samples for characterization of the
contained materials.
TP-4, TP-5 and TP-6 are for investigating the cause of
previously identified geophysical anomalies. In add it ion,

TP-5 is located to assess subsurface conditions in the
vicinity of a former mobile tank.
TP-7 is to investigate subsurface conditions in the former
bulk liquid storage area.
TP-8 is to investigate an area shown as being a slope
underlain with metal adjacent to the landfill in Figure 8 of
the RI/FS Work Plan. This area is identified as a potential
fill and debris area from previous investigations (USEPA.
December 1985). This test pit was relocated from the
location shown in the RI/FS Work Plan which was situated over
the culvert. The culvert will be investigated in subsequent
phases of the RI based on the findings of Phase I.
TP-9 is to investigate subsurface conditions in the
southeast corner of the Site which was reported to be an area
of concentrated drum storage activities.
TP-10 is to investigate subsurface conditions and determine
it drums are buried in an area where drums are visible on the
ground surface.
TP-11 and TP-12 (formerly B-11 and B-12) are to investigate
subsurface conditions in the two pits which were previously
used during the 1977-1978 Site cleanup ior holding drum
sludges and liquids. These two locations were to be

investigated using soil borings according to the RI/FS Work
Plan. However, test pits are deemed to be more appropriate
for this situation as a test pit will allow a visual
assessment of.the waste pit size and contained materials .
The need for excavation of additional test
pits during this phase of the investigation will be
determined by field personnel based on their analysis of
collected field data. In the event that the areal limits of
the landfill are not readily apparent from the surficial
topography, additional excavations may be conducted to
visually locate the landfill perimeter. Field personnel will
assess the need to delineate any areas which are found to
contain buried drums.
A.4.2.2 Excavation and Sampling Protocols
1. Excavation Protocols
Test pit locations will be finalized in the
field immediately prior to excavation. Scale measurements
from aerial photographs and observable Site features such as
topography, surficial debris and evidence of stressed
vegetation will be used to locate test pits. The locations
of previously identified geophysical anomalies will be
confirmed with a limited magnetometer survey over the

i'mmediate area of the proposed excavation. A magnetometer
survey will be conducted over the surface of the on-Site
landfill to identify any anomalies within the landfill area.
If such anomalies are found, two will be selected for the
test pit excavations. Otherwise, the test pits will be
located one-third and two-thirds along the length of the
landfill. The locations of the two former waste pits, TP-11
and TP-12, will be confirmed with the additional assistance
of staff from the State of North Carolina, if_possible. The
magnetometer will be used at all test pit locations prior to
excavation to determine if there is a potential buried hazard
to field personnel.
Test pits will be excavated with a
wheel-mounted backhoe to permit visual characterization and
access for sampling. During excavation, clean and
potentially contaminated excavated materials will be
segregated into separate stockpiles. Material which will be
considered clean include the cap soil on the landfill and the
top two ·feet from areas of potential residual contamination.
Excavated soil will be placed on polyethylene sheeting to
minimize the potential for introducing contaminants onto the
existing ground surface. Backfilling of the test pits will
be in the reverse sequence to excavation to ensure that soil
potentially containing hazardous substances is covered by
clean soils, The excavation of test pits will be conducted

program presented in Submittal C to ensure the safety of
on-Site personnel, the general public and the surrounding
environment.
Test pit excavations will be conducted in
such a manner that only the backhoe bucket will require
decontamination in the event that soil containing hazardous
substances is encountered. The backhoe will be
decontaminated between test pits and also prior to handling
clean backfill if deemed appropriate by the field Engineer.
Decontamination will follow the protocols presented in
Section A.4.5.
Test pits will be excavated to a maximum
depth of ten feet. The depth will be reduced in the event
that groundwater is encountered prior to the 10-foot depth.
Prior to entry for sampling purposes, the pit sidewall will
be sloped, supported or a protective cage installed to ensure
the safety of entry personnel in excavations deeper than
five feet or where Site conditions warrant protective
devices.
2. Sampling Procedures
Soil samples will be collected from the faces
of test pits by sampling personnel. Sampling prot~cols for
the test pit samples will be as followst!ONESTOGA•ROVERS & ASSOCIATES

The pit face from which samples are to be collected will
be cleaned using decontaminated hand tools prior to
sample collection. The pit face will be scraped clear of
loose material and soil smeared by the backhoe bucket
from top to bottom to an average depth of one inch.
2. An HNu meter will be used to survey the cleared pit face
for the presence of organic vapors. Organic vapor
readings and their corresponding depths and adjacent
physical features will be noted in the test pit log. The
test pit log will include observations on air quality,
soil stratigraphy, apparent or potential interfaces
between fill materials and native soil, wet zones if
present, and visible indications of soil/water
contamination. Field personnel may elect to calibrate
HNu meter readings against organic vapor readings from a
flame ionization detector (OVA or equivalent) if it is
deemed appropriate.
3. A composite soil sample for chemical analysis will be
collected from each pit excavated. The sample will be
collected starting below the interface of any clean
overlying material (i.e. landfill cap or fill placed
during previous cleanup operations) and continue to the
bottom of the pit.

plain flint glass containers as a record of the sample
taken.
7. A blind field duplicate sample will be collected at a
frequency of one per ten soil samples collected.

A.4.3 SOIL BORING AND MONITORING WELL INSTALLATIONS
A.4.3.1 Purpose/Scope
1. Monitoring Well Installations
Groundwater monitoring wells will be
installed to characterize the geologic and hydrogeologic
conditions underlying the Site and to determine if
groundwater contamination has resulted from previous Site
operations. The well installation program will:
i) define the subsurface geology of the Site;
ii) define aquifers which are present in the overburden and
the bedrock;

determine the hydraulic conductivity of the overburden
and the shallow bearock aquifer, is such exist;
determine the groundwater flow patterns and the
horizontal and vertical hydraulic gradients within and
between each of the overburden and shallow bedrock
zones where such aquifers exist; and
provide for the collectibn of soil, bedrock, and
groundwater samples for chemical and physical
analyses.
A total of 14 monitoring wells will be
installed at seven nested locations as shown on Plan A.3
(designated by MW-#). The rationale for the monitoring well
locations are as follows:
MW-1 (formerly B-1) is to provide background information.
This well nest location will be situated outside of the
fenced Site in an upgradient position away from potential
areas of residual contamination. The local groundwater flow
pattern is anticipated to be towards the north based on
regional topography and drainage.
MW-2 (formerly B-2) is to determine the presence of any
contaminants in groundwater due to a former drum storage area

(USEPA. December 1985). The well nest will be located
immediately downgradient of the depicted area.
MW-3 (formerly B-4) is to determine the groundwater quality
downgradient of the on-Site landfill.
MW-4 (formerly B-3) is to determine the impact ·of the
landfill on groundwater quality to the east of the landfill.
In addition, the well nest will provide information on the
impact of potential debris storage and fill activities which
are tentatively identified in the March 17, 1969 aerial
photograph (USEPA. December 1985).
MW-5 (formerly B-5) is to determine the impact of the Site
operations at what is considered to be the most likely
downgradient well nest on Site. This location was selected
to be downgradient of an area of dark-toned material and
standing liquids identified on an aerial photograph taken
November 18, 1975 (USEPA. December 1985) and which appears
to be suffering from vegetative stress on an August 12, 1985
aerial photograph (USEPA. December 1985).
MW-6 (formerly B-6) is to investigate groundwater conditions
downgradient of the area·formerly used for distillation
operations and bulk liquid storage. This well nest will be
installed on the former plant slab and may provide additional

information concerning any spillages from the tanks reported
to be housed in the buildings.
MW-7 (formerly B-7) is to determine the impact of an area
identified as containing dark-toned material, debris and
possible standing liquids on the November 18, 1975 aerial
photograph. The well nest will be located immediately
downgradient of this area. Hydraulic data from well nest
MW-7 in conjunction with that from nest MW-6 will permit an
evaluation of the potential for groundwater movement to the
east towards the Catawba River.
2. Soil Borings
Soil borings will be drilled in the
overburden in addition to the borings required for the
installation of the monitoring wells. These borings will
provide additional geologic characterization of the
overburden soils and provide for the collection of additional
soil samples for analysis.
A total of 5 soil borings.will be drilled in
the locations shown on Plan A.3 (designated by BH-#). The
rationale for the boring locations are as follows:
BH-1, BH-2 and BH-3 (formerly B-8, B-9 and B-10,
respectively) are to investigate subsurface conditions
underlying former drum storage areas identified on an aerial
photograph dated March .1 7, 1969 ( USE PA. coR~s.~rrr.l?,e.r:)\'¾'.:.'?,§5z) :\SSOCIATES

BH-4 is to investigate subsurface soils in the area of
dark-toned material and standing liquids identified on the
November 18, 1975 aerial photograph.
BH-5 is to investigate the area identified as a ground stain
on an aerial photograph dated February 12, 1968 (USEPA .
December 1985) and which appears to be in or near an area of
poor vegetative growth on a subsequent August 12, 1985 aerial
photograph (USEPA. December 1985)
Field personnel will assess the need for
additional soil borings in the field. Candidate areas will
include those showing obvious vegetative stress which are
not located in storage areas identifiable from aerial
photographs nor located coincident with previously identified
geophysical anomolies.
The above soil boring program differs from
the program presented in the RI/FS Work Plan in several
aspects. Borings BH-1, BH-2 and BH-3 are located in the
zones of potential residual contamination rather than
downgradient of these areas as called for in the RI/FS Work
Plan. Boring BH-4 and BH-5 have been added to investigate
areas of apparent residual soil contamination. These
modifications are deemed appropriate considering that the
Phase I effort is a characterization study rather than a

for in the RI/FS Work Plan (B-11 and B-12) have been
converted to test pits (TP-11 and TP-12) as outlined in
Sect ion A. 4. 2.
A.4.3.2 Drilling and Sampling Procedures
The protocols to be used to install the
boreholes for the proposed monitoring wells and soil borings
are described in the following subsections.
1. Permits and Access Agreements
The State of North Carolina requires that
contaminant monitoring wells be permitted. Permit
applications will be made and permits obtained before the
monitoring wells proposed in this Site investigation are
installed. These permits will be obtained in advance of well
installation to minimize interference with the well
installation schedule. A sample copy of the required permit
is presented in Attachment I.
The owner of the property on which the
background wells are to be located will be contacted in
advance of the well installation program. A site access
agreement wi 11 be obtained prior to commenc.ing,.w.9r,k .• ,5 ,In5t helATES \.,Vr~t:..:, 1 '--~I'\~, ,v v .:n 01 '"' .:,vv

event that a site access agreement cannot be obtained by the •
PRPs within a reasonable period of time, the USEPA will be
notified and requested to obtain access.
2. Overburden Drilling
Overburden drilling will be required to
install all wells and complete each borehole in this field
program.
At each nested well location, the overburden
portion of each deep monitoring well will be advanced first,
using 4 1/4-inch inside diameter (8-inch outside diameter)
hollow stern augers until competent bedrock is encountered.
Soil samples will be collected continuously during augering
to identify and classify soil materials.
All soils samples will be collected using the
st and a rd pen et rat ion test met hod (ASTM 1586-84) or a
continuous sampling system should soil conditions allow its
use.
Soil samplers will be cleaned between samples
as per Section A.4.5. All soil samples collected will be
described and classified according to the Unified Soil
Classification System (USCS) and then stored in glass jars
for geologic record. All samples retained for geologic CONESTOGA-ROVER,, & ASSOCIATES

During sampling, HNU readings in the head
space ot the sample jars will be taken and recorded, as an
indication of the presence of volatile organic
contamination as soon as possible after collection. All soil
cuttings will be spread on polyethylene sheeting near the
borehole.
Upon auger refusal, the hollow-stem augers
will be removed from the borehole. The borehole will be
reamed to ten inches in diameter using a tricone bit and
wet-rotary drilling methods. The 10-inch hole will be
advanced two feet into competent bedrock.
Steel casing,. six inches in diameter,
complete with centralizers, will be installed in the
borehole, two feet into bedrock, where it will be grouted
into place as described below.
Grout will consist of a cement/bentonite
slurry and will have a mixture ratio of 6.5 gallons of water
per 94-pound bag of normal portland cement producing a slurry
weight of 15.6 lb/gal. Approximately four pounds of
bentonite per sack of cement will be added to the slurry.
The amount of bentonite will not exceed 5 percent of the
mixed slurry to avoid excessive shrinkage of the cement.

The grout will be pumped into the annular
space through a trernie pipe/packer assembly located in the
casing near the bottom of the boring. The discharge end of
the grout rod will be fitted with a ball valve to reduce the
infiltration of grout into the well casing. The pumping of
grout will continue until undiluted grout returns through the
annulus to the ground surface. The casing will then be
pushed into the bedrock to further seal the annulus. The
grout will be allowed to set for a minimum period of 24 hours
before bedrock coring commences.
Once the casing has been grouted in place,
the shallow well boring will be advanced utilizing the hollow
stern augering technique with one undisturbed soil sample
(Shelby tube) being collected at the targeted screen
int erv·a1.
All fluids generated during drilling will be
contained and analyzed to determine final disposition.
3. Bedrock Coring
The bedrock portion of each deep monitoring
well will be completed by coring techniques. All coring will
be pertorrned in accordance with ASTM D2113-83, using clear,
potable water as the circulation medium. A sample of the
potable water used in the drilling and coring operations will

be collected and analyzed for USEPA Target Compound List
(TCL) compounds. The corehole will be advanced using an "N"
size corebarrel (1.88-inch diameter core and 2.98-inch
diameter hole).
The borehole will be cored continuously, in
10-foot intervals, for the entire depth. The corehole will
extend a minimum of 15 feet below the bedrock surface, or
until a water-bearing fracture zone is encountered.
Each core run will be laid in core boxes in
accordance with the above noted ASTM standard and visually
inspected by a qualified geologist in the field. The
geologist will complete a geologic log of the core with
particular attention being noted of fractures, aperture size,
orientation, spacing, filling, roughness and discontinuity
type. Rock quality designation (RQD) tests will be conducted
over the length of the core. The procedure for applying the
RQD is presented in Attachment II. During drilling the water
loss and gains will be closely monitored to identify fracture
zones.
Upon reaching the final depth, the drilling
fluid will be circulated to remove rock cutting from the
borehole walls. All fluids generated during coring will be
contained and analyzed to determine final disposition.

All core boxes will be clearly labelled to
indicate the tollowing: job name, job number, hole number,
run number, run interval and date. All core boxes will be
covered in plastic and placed in the secure area once they
are logged and secured.
4. Additional Soil Borings
All soil borings additional to the ones
required for the well installations will be advanced
utilizing the hollow stern augering technique. Soil samples
will be obtained continuously to a depth of 15 feet or to the
groundwater table, whichever is encountered first.
Each borehole will be backfilled with its
soil cuttings where possible. All remaining soil cuttings
will be disposed of according to Section A.4.6.
5. Soil Sampling for Chemical Analyses
Soil samples from the additional boreholes
and shallow monitoring wells will be obtained for chemical
analyses in th~ following manner.
Each soil sample will be collected using a
continuous soil sampling system or a 3-inch diameter split
spoon sampler in conjunct ion with the h2JJ.f'J"rc,u~~Jl01,'lN,~eJ}.~\foc1ATES

Samples will be obtained at depths of
approximately three feet, eight feet and 13 feet below ground
surface.
Samples will not be collected below the
groundwater table. If the groundwater table is encountered
at depth above 13 feet, the final sample for chemical
analyses shall be collected above this elevation so that the
sample interval straddles the water table.
Soil samples will be prepared in the
following manner:
a) The sampler will be laid on a table and carefully opened
to avoid sample disturbance.
b) Using a precleaned stainless steel knife, a thin section
will be removed from the top and bottom of the sample,
and discarded, as shown in Figure A.2.
c) The remainder of the core will then be cut longitudinally
with a clean cutting tool. From the centre of the core a
continuous soil sample will be taken using a clean
stainless steel spatula. The sample will be placed into
a 500 mL glass jar. The precleaned jars will be fitted
with teflon lid liners.

A clean pair of disposable latex surgical gloves will be used
to handle each sample.
A.4.3.3 Monitoring Well Installation Procedures
Each nested deep well will be completed as a
2-inch diameter monitoring well in the following manner. The
geologic log of the core will be examined to locate fracture
zones. Based on the observed distribution of fractu_res and
RQD, a preterred monitoring interval will be selected, The
corehole will then be reamed to a 6-inch diameter to the
desired depth. A 2-inch diameter stainless steel screen of
predetermined length attached to 2-inch diameter Schedule 10,
Type 304, stainless steel riser will be installed through the
surface casing to its desired depth. An inert sandpack
(20-40 mesh) will be placed in the annulus space to a height
of approximately two feet above the screen. A 2-foot thick
bentonite pellet seal will be placed above the sandpack. A
tremie pipe will be lowered into the borehole and
cement/bentonite grout will be introduced to the annular
space between the riser pipe and borehole wall. Pumping of
grout will continue until undiluted grout returns to the

ground surface. After the grout has set overnight, the
remaining portion of the unfilled portion of the borehole
will be tilled with cernent/bentonite to within two feet of
the ground surface.
The shallow monitoring well at each nested
location shall be completed in the saprolite/overburden
in the following manner. The overburden portion of the
boring will be advanced using 4 1/4-inch inside diameter
hollow stern augers to the screened interval, based on data
obtained from the deeper boring at the nested location. The
depth shall be chosen such that the depth at which the well
screen is to be set will straddle the water table.
The monitoring well inst al lat ion will then be
completed similar to the deeper installation at this location
using the hollow stem augers as a temporary casing. A 6-inch
diameter lockable protective casing will be installed.
Upon completion of the monitoring wells, each
protective surface casing will be fitted with a permanent
lockable cap. A weep hole will be drilled in the casing to
facilitate drainage after development and purging. A
concrete protection collar measuring three feet by two feet
by one foot in depth will be placed around the protective
casing. The collar will be sloped such that it promotes the

Each monitoring well will be clearly. labelled
with its own unique identification number in an area o,here it
is protected from possible vandalism.
Completion details for a typical well nest is
shown on Figure A.3.3.
A.4.3.4 Well Development
All wells will be developed to a silt-free
condition, if possible, following installation by bailing or
pumping. Well development will continue until water flows
freely into the well and the water is silt free. Field
measurements of pH, conductivity and temperature will be
taken of the evacuated water. Development water at each
monitoring well location will be placed in 55-gallon drums.
Upon completion of development at each location the drums
will be transported to the interim storage area and the
development water will be transferred to a temporary storage
tank. When the sampling program is completed or when the
tank is full, whichever occurs first, the contents of the
tank will be sampled and analyzed in order to determine
disposal requirements.

A.4.3.5 Response Testing
Revision No: 0
Date: 05/31/88
Page: 48
In situ hydraulic conductivity testing will
be completed to determine the hydrogeologic properties of the
various stratigraphic units encountered. Single well
response tests will be performed at each monitoring well.
These tests involve changing the water level within a well
and monitoring the time required for the level to return to
the static position. Two types of response tests are
normally performed including falling head tests, where a slug
of known volume is introduced into the standing water column,
and rising head tests, where a known volume of water is
removed from the well and the recharge is monitored.
Several methods have been developed tor
determination of hydraulic conductivity values from response
test data. These methods consider well morphology,
hydrogeologic setting, and time lag response as factors to
calculate in situ hydraulic.conductivity. The method of
Hvorslev (1951) is commonly used to analyze the results of
response tests. Other methods which may be employed include
Cooper et al (1967), Papadopulos et al (1973), and Bouwer and
Rice (1976).

Before purging and sampling, the water level
in each monitoring well will be measured using an electric
sounding device. This method involves lowering a probe into
the well; when the probe contacts the water, an electric
circuit is completed. The probe is connected to a
two-conductor electric wire that is calibrated in 0.01-foot
intervals, mounted on a reel containing batteries (l.S_volt)
and has an audio alarm which emits a signal when the circuit
is closed.
Water levels will be recorded in the field
log book to the nearest 0.01 foot. Measuring devices will be
decontaminated after each use as specified in Section A.4.5.
Prior to use in the field, the measuring device will be
calibrated using a steel measuring tape.
Non-aqueous phase liquid (NAPL) thicknesses
and levels, if pr·esent, will be measured using an interface
probe. The interface probe is a hand-held battery-operated
device utilizing an optical liquid sensor and electrical
conductivity to distinguish between water and hydrocarbons.
The interface probe will be calibrated and decontaminated as
described above.

A.4.3.7 Groundwater Sampling
Revision No: 0
Date: 05/31/88
Page: 50
One round of groundwater samples will be
collected from all proposed monitoring wells in this phase of
the work. Samples will be collected 24 hours after well
development.
The sampling procedures for the groundwater
monitoring wells are described below. The procedures are
used to maintain consistent and reproducible methods in
obtaining and analyzing samples from the monitoring wells.
The procedures used are based on:
Procedures Manual for Ground-Water l'1onitoring at Solid
Waste Disposal Facilities, EPA-530/SW-611, August 1977
Methods for Chemical Analysis of Water and Wastes,
EPA/600/4-79-020, March 1979

All proposed monitoring wells will be sampled
according to the following protocols:
1. New disposable latex gloves· will be used when sampling
each well. Gloves will be changed prior to collection of

2. The sampler will measure and record the depth to water in
each well to the nearest 0.01 foot using an electric
tape. The electric tape will be decontaminated prior to
use in each well as per Section A.4.5.
3. Prior to sampling, each well will be purged using?
stainless-steel bottom filling bailer or a submersible
pump to remove a minimum of three and a maximum of five
times the standing water volume in the well, or/until
dry. In the event that a well is bailed dry prior to
achieving three well volumes, groundwater will be
permitted to recover to a level sufficient for sample
collection. The time that the well was bailed dry will
be noted and well recovery will be monitored. Upon
recovery, one. final bailer volume will be removed and
discarded prior to sample collection. Prior to use in
the initial and all subsequent monitoring wells, bailers
will be precleaned as described in Section A.4.5. All
groundwater not collected for analyses will be contained,
sampled and stored for disposal pending the receipt of
analytical results.
4. Field measurements of pH and conductivity (using a DspH-3
pH/3 RGE Conductivity Meter) and temperature (using a YSI
Model 33 SCT meter) will be recorded following removal of
each standing well volume and prior to sample collection.
Calibration of field instruments will be undertaken prior

After the required standing well water has been purged,
water samples will be collected usin<,J a closed top
cleaned stainless steel bailer attached by a stainless
steel leader to a nylon rope. New nylon rope will be·
used for each monitoring well.
6. No groundwater samples collected will be field filtered.
Samples which are turbid will be noted. Turbid samples
will not be decanted in the laboratory to generate
sediment free aliquots and will be analyzed on an ''as is''
basis. In the event that water from a well exhibits
turbidity, twice the normal volume for unfiltered samples
as outlined below will be collected.
7. Containers for sample collection and preservation
requirements will be determined as required by the
analytical parameters as detailed in Section A.6. All
sample bottles will be provided by the laboratory and
will be prepared using standard laboratory validated
washing procedures. The sample bottles will be delivered
to the Site in sealed containers.
8. A blind field duplicate sample will be collected at a
frequency of one in ten locations.

spike duplicate sample will be taken from a well where
samples do not require consideration for turbidity, if
possible. Samples will be collected from the well as
outlined in (7) above, but at twice the normal volume.
The analysis request sheets sent to the laboratory will
indicate the sample I.D. of the matrix spike samples.
10. A rinsate blank (bailer blank) sample will be collected
at a frequency of one in_ ten locations. The bailer blank
sample will consist of deionized water poured into, and
then sampled out of, a bailer cleaned using the
prescribed rinse sequence (see Section A.4.5). This will
provide a quality assurance check on the field
decontamination procedures, employed for the bailers
between wells.
11, A field blank will be collected at a frequency of one in
ten locations. The field blanks will be prepared by
pouring deionized water directly into the appropriate
sample bottles in the field as outlined in (7). This
will provide a quality assurance check on the sample
bottles and the deionized water used.
12. All disposable gloves, rinsings and nylon ropes will be
placed in DOT approved 55-gallon drums and stored in a
designated storage area on Site in accordance with

A.4.4 SUkFACE WATER AND SEDIMENT SAMPLING
A.4.4.1 Purpose/Scope
Surface water and sediment samples will be
collected to characterize surficial flows leaving the Site
and the sediments accumulated in drainage courses. The
generated data will permit an evaluation of the potential
hazard associated with surface waters draining from the Site.

determine the impact of the Site on downstream water
quality and sediments;
characterize waters and sediments located in ponded
areas of the Site; and
characterize the water and sediment from the perennial
spring on Site.
A total of seven locations will be sampled as
shown on Plan A.3 (designated by SS-#). The location
numbering system corresponds to those shown in the RI/FS Work
Plan. The rationale for these locations are as follows:
SS-1 and SS-5 are to determine the background water and
sediment quality in Tributary B upstream of the Site. Both
locations were selected as ss-5 is reportedly downst.ream of
other industrial discharges to Tributary B which may be
impacting the stream. Location SS-1 will provide background
data unaffected by other discharges and be representative of
upgradient areas. Three additional locations upstream of the
Site referred to as SS-2, SS-3 and SS-4 in the RI/FS Work
Plan, will not be sampled as part of the Phase 1 effort.
These additional locations appear to be for the delineation
of the other industrial discharges to Tributary B which would
be inappropriate within the RI/FS process for this Site. The
analytical results from samples collected at SS-5 will be
compared with the results from analyses of other samples
collected on Site, and at SS-1 to identify contaminants from

determined after a review of the Phase 1 analytical results.
SS-6 is to characterize the standing surface water area as
shown in the RI/FS Work Plan.
ss-7 is to characterize liquids and sediments in the box
structure containing the spring.
SS-11 is to characterize water and sediments downstream of
all discharges/runoff from the former process area. Three
additional locations, referred to as SS-8, SS-9 and SS-10 in
the RI/FS Work Plan, will not be sampled during Phase 1.
These locations will be sampled, as appropriate, in
subsequent phases of the RI for the delineation of parameters
identified in Phase I. The analysis of soil samples from
test pits and borings adjacent to this area will indicate the
substances to be delineated.
SS-12 is to determine the background quality in Tributary A
upstream of the Site. This location corresponds to SS-12 in
the RI/FS Work Plan but has been relocated to the downstream
side of S.R.2035. This is deemed appropriate as chemical
substances may have originated from road runoff upstream of
the Site.

SS-14 is to characterize water and sediments of Tributary B
prior to confluence with Tributary A. SS-12 and SS-14 will
be assessed jointly to determine if downstream impacts may be
occurring. Additional downstream sampling will be based on
this assessment.
Two additional locations, SS-13 and SS-15 in
the RI/FS Work Plan, will be deferred until Phase II when
they will be sampled, as appropriate, for delineation
purposes.
Two additional locations downstream of the
Site and referred to as SS-16 and SS-17 in the RI/FS Work
Plan will not be sampled for PCB analysis in the Phase I
effort. These locations will be sampled for PCB and other
substances attributable to the Site in Phase II as part of
any subsequent delineation effort. This will ensure that any
PCB data can be collaborated with analyses for substances
identified at Site in Phase I.
A.4.4.2 Surface Water Sampling Procedures
Surface water samples will be collected in
accordance with the following protocols:
1. A new pair of disposable latex gloves will be used when
collecting each surface water sample. Additional glove
changes will be made as conditions warrant.

A.4.4.3 Sediment Sampling Procedures
A sediment sample will be collected at each
surface water sampling location following collection of the
corresponding surface water sample. Sampling protocols for
the sediment samples will be as follows:
1. A composite sediment sample will be collected from each
location, The composite sample will consist of aliquots
from three sampling points. At stream sampling
locations, the sampling points will be located at
one-third, one-half and two-thirds across the wetted
streambed. At ponded locations, sampling points will be
selected to provide an even distribution over the area.
2. Sediment samples will be collected by driving a
split-spoon sampler deeper than one foot into the

Sample shipments will be iced by placing
zip-lock bags of ice and/or cooler packs around the sample
containers. Any remaining space will be filled with
vermiculite or equivalent.
The chain-of-custody record for each sample
shipment will be packaged in a waterproof envelope and sent
with the samples to the assigned laboratory. A separate
chain.-of-custody form wi.11 be developed for the contents of
each cooler and will be included within the respective
cooler.
Samples packaged in coolers as described
above will be transported by courier to the laboratory on a

In accordance with the RI/FS Work Plan, the
Phase I SI will be completed 20 weeks following the approval
of the project operations plan (POP).
This schedule assumes that the field work
will proceed under favorable weather conditions. Should
schedule delays occur, they will be addressed as they occur
and all necessary attempts will be made throughout the
program to avoid them. Updates of the schedule will be
included with each monthly progress report.
Interim deadlines for Phase I related to
Phase I tasks such as surface water sampling and well
installation, are considered approximate and may vary
slightly from the RI/FS W.ork Plan in order to accommodate
weather conditions and/or contractor scheduling.

ROCK QUALITY DESIGNATION (RQD) -DEERE (1986)
In order to provide a simple and direct means
of indicating rock-mass properties, Deere (1986) developed
the Rock Quality Designation (RQD), The RQD is based on a
modified core recovery procedure which, in turn, is based
indirectly on the number of fractures and the amount of
softening or alternation in the rock mass as observed in the
rock cores from the borehole, Core recovery is the ratio of
the length of core recovered to the length drilled (i.e. no
recovery= 0 and full recovery= 100). Instead of counting
the fractures, an indirect measure is obtained by summing the
total length of core recovered by counting only those pieces
of hard and sound core which are 10 cm (4 in.) or greater in
length and dividing that sum by the total length of that
run.
RQD should not be applied to core less than
5.4 cm (2 in.) in diameter as a false RQD may be obtained
because smaller cores can be frequently broken during the
coring operation.
Care must be taken when removing the core
from the core barrel. If a core is broken by handling or
during drilling, the fresh broken pieces are fitted together
and counted as one piece.

Some judgement is necessary in the case of
thinly bedded sedimentary rocks and foliated metamorphic
rocks. The method is not so exact in these cases as it is
for igneous rock, thick bedded limest-one, sandstones, etc.
However, this procedure has been applied successfully even
for shales, although it-'. is necessary to log the cor·e
immediately upon removing them from-the core bartel before
air-slaking and cracking can occur.
This procedure obviously penalizes the rock
where recovery is poor. This is appropriate because poor
recovery usually reflects poor quality rock. However,-poor
drilling techniques and equipment can also cause poor
recovery. It is: for this reason, that proper: equipment and
procedure along with competent superv is:i.on of the drilling
procedure· are impe·rat i ve ..
As simple-as the procedure appears-, it has
_been found that as an indicat6r of general quality of rock
for engineering purposes, the numerical ~alue of the RQD is
more sens·it i ve and cons i-st ent than gr·oss-percent age core
recovery ..
Below is a simple example of using RQD.

B.4 QUALITY ASSURANCE OBJECTIVES FOR
MEASUREMENT DATA
Revision No: 0
Date: 05/31/88

The overall QA objective is to develop and
implement procedures for field sampling, chain-of-custody,
laboratory analysis and reporting that will provide accurate
data. Specific procedures to be used for sampling,
chain-of-custody, calibration, laboratory analysis,
reporting, quality control, audits, preventative maintenance
and corrective actions are presented in other sections of
this QAPP.
The purpose of this section is to define
the goals for the level of QA effort: namely, accuracy;
precision and sensitivity of analyses; and completeness,
representativeness, and comparability of measurement data
from the analytical laboratories. QA objectives for field
measurements are also discussed.
B.4.1 LEVEL OF QA EFFORT
To assess the quality of data resulting from
the field sampling program, field duplicate samples, rinsate
blank samples, bottle blank samples, trip blank samples, and
samples for matrix spiking purposes will be taken (where
appropriate) and submitted to the analytical laboratory.

For all field samples collected, field
duplicate samples will be submitted at a Erequency of one per
ten investigative samples or, should a sampling event consist
of less than ten samples, a field duplicate sample will be
submitted. Matrix spike and matrix spike duplicate samples
will be analyzed at a minimum frequency of one in 20 for
each. Rinsate blank samples (bailer blank samples and
sampling equipment blanks) will be submitted at a frequency
of one per ten well purging/sampling equipment cleanings or
(if less then ten are generated over a one-day period) at
least once per day of well purging/sampling equipment
cleanings.
Field bottle blank samples (consisting of
deionized water poured into sample containers) will be
submitted at a frequency of one per day, for each day of
sample collection. This will provide a measure of potential
bottle or deionized water contamination or contamination from
the environment.
Trip blank samples for Volatile Organic
Compound (VOC) analysis (prepared by the laboratory and
consisting of deionized water poured into the sample vials)
will be shipped by Radian to the Site, at a frequency of one
trip blank per. shipment of samples. Trip blank samples will
not be handled by the personnel collecting the field samples

blanks and trip blanks) will be analyzed to check procedural
contamination and/or ambient conditions and/or sample
container contamination at the Site that may cause sample
contamination. Field duplicate samples will be analyzed to
check for sampling and analytical reproducibility.
B.4.2 ACCURACY, PRECISION AND SENSITIVITY OF ANALYSES
The fundamental QA objective with respect to
accuracy, precision, and sensitivity of laboratory analytical
data is to achieve the QC acceptance criteria of the
analytical protocols. The accuracy and precision
requirements for samples analyzed in accordance with standard
USEPA protocols are specified in the appropriate USEPA
methods.
The QA goals for accuracy and precision are
summarized in Section B.10.
The method(s) precision (relative percent difference (RPD)
between duplicate analyses) will be d.,esi1oec~l\1bli:=J.~ctg~gi & ASSOCIATES

duplicate analysis. At least one sample in a.batch of ten
will be analyzed in duplicate. Precision shall meet the
criteria specified in the appropriate USEPA methods, and as
detailed on Table B.10.4.
-The method accuracy (percent recovery) for water and soil
samples will be determined by spiking selected samples with
compounds listed in Tables B.10.1 and B.10.3
(Section B.10.2). Accuracy will be reported as the percent
recovery of the test compound and shall meet the criteria
given in the appropriate USEPA Methods and as presented in
Table B.10.4.
The sensitivities required for these analyses
will be the target quantitation limits listed in Tables B.8.2
and B.8.3 of Section B.8.2.
B.4.3 COMPLETENESS, REPRESENTATIVENESS,
AND COMPARABILITY
It is expected that organics, analyzed in
accordance with specified USEPA methods will provide data
meeting QC acceptance criteria for 90 percent of all samples
tested. Completely valid data for additional water quality
parameters should be provided, and the reasons for any
variances from 90 percent completeness will be documented.

The sampling networks are designed to provide
data representative of Site conditions. During development
of these networks, consideration is given to past site
operations and disposal practices, existing analytical data,
remedial activities to date and physical setting. The extent
to which existing and planned analytical data will be
comparable depends on the similarity of sampling and
analytical methods. The procedures used to obtain the
planned analytical data are documented in this QAPP. It may
be necessary to verify similar documentation for existing
analytical data. Following completion of data collection,
the existing data base will be evaluated for
representativeness.
Comparability of laboratory analyses will be
ensured by the use of consistent units.

B.7 CALIBRATION PROCEDURES AND FREQUENCY
Revision No: 0
Date: 05/31/88
Page: 18
B.7.1 CALIBRATION OF LABORATORY EQUIPMENT
Calibration of the GC/MS system will be
performed daily at the beginning of the day or with each 10
to 12 hours of instrument operating time. This will consist
of mass calibration with FC-43 (perfluorotributylamine), ion
abundance calibration with DFTPP (decafluorotriphenyl-
phosphine), or BFB (bromofluorobenzene) and verification of
response factors for each of the test compounds using
standards of known concentrations. DFTPP will be used to
verify the ion abundance calibration for the GC/MS analysis
of semivolatile organic compounds, while the BFB will be used
to verify the ion abundance calibration for the GC/MS
analysis of volatile organi~ compounds. Response factors for
the compound of interest will be determined daily using the
midpoint of the original calibration curve and will be
compared with the average values from a five-level
calibration performed at the beginning of the project or
following major instrument repair. A deviation in response
factors of over 20 percent for more than two compounds will
require evaluation of the problem and possibly generation of
a new calibration curve. Other details of the required
calibration quality control measures will be consistent with
those described in USEPA Methods 8240 and 8270 (SW-846, 3rd
edition, September 1986).

Quantification of samples that are analyzed
by GC/MS will be performed by internal standard calibration.
Five or six internal standards will be used. Those routinely
used include: l,4-dichlorobenzene-d4, naphthalene-ds,
acenaphthene-d8 , phenanthrene-d10, chrysene-a12,
perylene-d12 (for semivolatile compounds) and
bromochloromethane, 1,4-difluorobenzene and
chlorobenzene-d5 (for volatile analysis).
Quantification of samples that are analyzed
by GC with element selective detectors will be performed by
external standard calibration. Standards containing the
compounds of interest will be analyzed at various
concentrations (minimum three levels) to establish the linear
range of the detector. Following the multilevel calibration,
analysis of samples will be initiated. Single point
calibration will be performed at the beginning of each day
and at every tenth injection. The response factors from the
single point calibration will be ~hecked against _the average
response factors from multilevel calibration. If a deviation
in response factors greater than 20 percent occurs then
system recalibration will be performed. Alternatively, fresh
calibration standards will be prepared and analyzed to verify
instrument calibration.
Quantification of samples that are analyzed
by inductively coupled plasma (ICP), flame or graphite

furnace atomic absorption (AA) techniques will be performed
by external standard calibration. For flame and graphite
furnace AA, calibration blank and at least three calibration
standards will be analyzed to establish the linear range of
the detector. For ICP AA analyses a calibration blank and at
least one calibration standard will be analyzed to establish
the analytical curve. Calibration verification results must
fall within the control limits of 90-110% of the three
values. Instruments must be calibrated daily and each time
the instrument is set up.
Continuing calibration checks and calibration
blank analyses will be performed at a minimum frequency of
10% or every 2 hours during an analysis run, whichever is
more frequent, and after the last analytical sample.
B.7.2 CALIBRATION OF FIELD EQUIPMENT
Calibration of the field instruments will be
done at the beginning of each sampling day. The field
equipment will be maintained, calibrated and operated in a
manner consistent with the manufacturer's guidelines and EPA
standard methods. Calibration of each field instrument is
described as follows:

Date: 05/31/88
Page: 21
The water level indicator length is inspected prior to
each use. Proper functioning of the sensor and
integrity of the tape is checked. If necessary, the
tape will be compared against a steel tape.
(b) Calibration of pH Meter
The pH meter will be calibrated with commercially
obtained pH 7, 4 and 10 buffer solutions. The pH
calibration will be temperature compensated, and will be
performed immediately before initiating a sampling
event. Calibration checks will be performed with every
sample collected. In the event that the result fails to
be within 0.1 pH units, the meter must be recalibrated
and all sampfes after the last calibration must be
re-measured.
Calibration will be performed in accordance with the
following procedure:
1) Rinse the probe in deionized water;
2) Insert probe in a fresh pH 7 buffer solution;
3) Slide battery compartment cover back to the first
stop exposing the adjustment potentiometers;

4) Adjust the "CAL" potentiometer such that the display
reads 7.00;
5) Remove the probe; rinse in deionized water;
6) Insert probe in a fresh pH 4 or pH 10 buffer
solution;
7) Adjust the slope potentiometer until the correct pH
is displayed; and
8) Remove probe; rinse in deionized water.
(c) Calibration of the Specific Conductance Meter
The specific conductivity meter is factory calibrated,
but the calibration should be checked periodically and
the probe thoroughly rinsed between samples.
Calibration of the specific conductivity meter will be
performed as follows:
1) Rinse probe in deionized water;
2) Wipe probe and allow to dry;
3) The conductivity displayed should be zero in air;
4} Adjust the zero potentiometer if necessary;
5) Immerse the probe in a solution of known
conductivity;
6) Adjust the "SPAN" potentiometer such that the
correct conductivity is displayed; and
7) Rinse probes thoroughly with deionized water and
allow to dry.

B.8.2 DETECTION LIMIT REQUIREMENTS
Revision No: o
Date: 05/31/88
Page: 24
The data used to conduct the Groundwater
Investigation will have targeted method detection limits t~at
are consistent with those presented_in the appropriate USEPA
standard methods. ,
Tables B.8.2 and B.8.3 provide quantitation
limits targeted by the USEPA for Target Compound List (TCL)
parameters. Detection limits for organic compounds required
to be lower than those specified in the USEPA standard
methods will be attained through the use of additional sample
volumes.
The laboratory detection limits will be
demonstrated using protocols established in 40 CFR Part 136,
Appendix B, October 26, 1984. Verification of detection
limit attainment will be achieved by sensitivity checks of
the equipment using standards at concentrations of twice the
targeted quantitation limit. The standards will be run prior
to analysis of any samples for the project and weekly or
following recalibration of equipment throughout project
analytical activities.

B.9 DATA REDUCTION, VALIDATION, ASSESSMENT, AND REPORTING
B.9.1 GENERAL
Radian will perform analytical data reduction
and validation in-house under the direction of the laboratory
QA officer. The laboratory QA officer is responsible for
assessing data quality and advising of any data which were
rated ''preliminary'' or ''unacceptable'' or other qualifications
based on QC criteria outlined in USEPA SW-846 (Third Edition)
which· would caution the data user of possible unreliability.
Data reduction, validation, and reporting by the laboratory
will be conducted as follows:
-Raw data produced and checked by the analyst will be turned
over to the respective area supervisor.
-The area supervisor will review the data for attainment of
quality control criteria as outlined in established EPA
methods and for overall reasonableness.
Upon acceptance of the raw data by the area supervisor, a
computerized report will be generated and sent to the
laboratory QA officer.
-The laboratory QA officer will complete a thorough audit of
the analytical data reports at a frequency of one in ten,

sample re-analysis is required.
-Upon acceptance of the preliminary reports by the QA
officer, final reports will be generated and signed by the
laboratory project manager.
CRA's QA/QC coordinator will conduct an
evaluation of data reduction and reporting by the. laboratory.
This evaluation will assess the finished data sheets,
document control forms, blank data, duplicate data, and
recovery data for surrogate and matrix spikes. The material
will be checked for legibility, completeness, correctness,
and t-he presence of necessary dates, initials, and
signatures. The results of these checks will be assessed and
reported to the project manager and the contract laboratory,
noting any discrepancies and their effect upon acceptability
of the data.
Validation of the analytical data will be
performed by the QA/QC coordinator and the QA officer for
field activities. The process of data validation includes

chlorobenzene-d5 (for volatile analysis), will be spiked
into each sample extract or sample to be purged
immediately prior to the GC/MS analysis.
Method blanks will be run at a minimum frequency of one
for every 20 samples per matrix or with each batch if
there are fewer than 20 samples per batch.
In order to evaluate the matrix effect of the sample upon
the analytical method, one sample per 20, or one sample
per batch should the batch size be less than 20 samples,
will be fortified with selected test compounds and
analyzed in duplicate. The compounds recommended for
spiking are given in Table B.10.3. The matrix spike/
matrix spike duplicate recoveries will be compared against
those listed in Table B.10.4 and the data will be used to
evaluate the performance of the method.

thorough instrument maintenance twice a year. Routine
maintenance will be performed as per Manufacturers'
recommendations. Extra parts such as ion sources, filament
assemblies, mass analyzers, electron multipliers are in stock
at Radian. The GC/MS Operations Manager is_ responsible for
the preventive maintenance of the GC/MS instruments.
The preventive maintenance of the GC
instruments will be done on an as needed basis. Several
maintenance procedures will be conducted on a routine basis.
Manufacturers' recommendations provide the primary basis for
the established maintenance schedules.

Manufacturers' service contracts provide
primary maintenance for most major instruments (e.g. GC
instruments, atomic absorption spectrometers, analytical
balances, etc.). All aspects of routine and non-routine
instrument maintenance are recorded in logbooks, and a
logbook is dedicated to each instrument.

B.13 PROCEDURES FOR DATA REVIEW
Revision No: 0
Date: 05/31/88
Page: 43
Precision will be determined through
duplicate analyses. Accuracy will be assessed using spiked
sample analyses and performance audit analyses. Whenever
accuracy, precision or completeness deviates from the goals
itemized in Section 10.2, the source of the problem will be
determined and corrected.
B.13.l PRECISION
Precision as percent relative difference will
be calculated as follows:
Precision= ~f_1 __ x_2~I xlOO
where x 1 and X2 are the results of duplicate analyses.
8.13.2 ACCURACY
Accuracy as percent recovery will be
calculated from results of analyses of spiked samples as
follows:

A = the analyte determined experiment ally from the
spiked sample,
B = the background level determined by a separate
analysis of the unspiked sample,
C = the amount of the spike added.
Accuracy will also be assessed on
determinations of performance audit samples.
B.13.3 COMPLETENESS
Completeness will be calculated as the ratio
of acceptable measurements obtained to the total number of
planned measurements.

B.14 CORRECTIVE ACTION PROCEDURES
Revision No: 0
Date: 05/31/88
Page: 45
Corrective action indicated by audit results
or detection of unacceptable data will be determined by CRA's
Project Manager. Corrective action may include, but is not
limited to:
. reanalyzing the samples, if holding time criteria permit;
• resampling and analyzing;
evaluating and amending sampling and analytical
procedures;
accepting data with qualifications which will be based on
footnotes detailed in the Laboratory Data Validation
Guidelines for Evaluating Organics and Inorganics Analyses
(see Section B.9.1); and
. qualifying data as unuseable.
The type of corrective action required will
be outlined in a proposal by the QA/QC offices for analytical
and field activities in consultation with the Project
Manager. A particular corrective action alternative will be
implemented only after full agreement to the type of action
required.

Corrective action procedures on the part of
the Laboratory are require6 in the event that spiked sample
results fall outside the limits of data acceptability. In
general, corrective action is required if reference spike
(surrogate) spike data occur beyond acceptable limits (see
Tables B.10.2 and B.10.4, Section B.10.2). Corrective action
in the case of outlying surrogate or matrix spikes generally
involves one of the following:
-check calculations,
-check instrument performance,
-check for d~gradation or contamination of standards
-re-analyze sample.
These actions are taken in an effort to
distinguish between a system which is out of control and an
isolated occurence.

B.15 QUALITY ASSURANCE REPORTS
Revision No: 0
Date: 05/31/88
Page: 47
Final Reports will contain a discussion on
QA/QC summarizing the quality of the data collected and/or
used as appropriate to each phase of the project. The
Project Coordinator, who has responsibility for these
summaries, will rely on written reports/memoranda and
footnotes documenting the data assessment activities ·and the
performance and systems audits.
Each summary of sampling activities will
include a tabulation of the data including:
-blank and duplicate sample results;
-maps showing well locations; and
-an explanation of any sampling conditions or quality
assurance problems and their effect on data quality.
QA reports will be prepared by CRA's QA/QC
coordinator following each major sampling event. These
reports will include discussions of the following and their
effects on the quality of the data reported:
-sample holding times;
-laboratory/reagent blank data;

The Site investigative work to be conducted
for the Remedial Investigation at the Jadco-Hughes Site
(Site) in Gaston County, North Carolina is described in
Submittal A -Site Investigation Plan of the Project
Operations Plan. Such work may involve contact with soil,
surface water, stream sediment and groundwater which
potentially contain low levels of hazardous substances
including volatile organic compounds (VOCs) and/or
polychlorinated biphenyls (PCBs). It is anticipated that the
concentration levels of these contaminants will be much less
than that of their pure product form.
To ensure that any direct contact with
potentially contaminated material by Site personnel is
prevented, a Site Specific Health and Safety Plan has been
developed as presented herein. This Health and Safety Plan
has been developed to ensure the following:
i) that personnel working on Site are not significantly
exposed to hazardous substances,
ii) that the health and safety of the general public and
the surrounding environment is not compromised by the

potential off-Site migration of contaminated materials
due to this project, and
iii) compliance with applicable governmental and
non-governmental (American Conference of Governmental
Industrial Hygienists) regulations and guidelines. In
particular, the amended rules of the Occupational
Health and Safety Act for Subpart Hof Part 1910
(29 CFR 1910.120) will be implemented for all Site
work.
For the purpose of this Health and Safety
Plan, all sampling activities performed on the Site involving
contact with potentially contaminated materials will be
considered contaminated operations requiring personal
protective equipment. A detailed description of the personal
protective equipment required is presented in Section C.2.9.

The Health and Safety Plan specified herein
will provide for a safe and minimal risk working environment
for on-Site personnel. It also provides for emergency
response procedures and attempts to minimize the potential
adverse impact of investigative activities on the general
public and the surrounding environment.
Sampling activities at the Site will involve
contact with soils, sediments, groundwater, and surface water
which may contain hazardous chemicals. All Site personnel
will be required to comply with all provisions of this Health
and Safety Plan.
C.2.2 SITE CHARACTERIZATION AND POTENTIALLY
HAZARDOUS COMPOUNDS
The Site has not been fully characterized to
date. Listings of chemicals formerly handled at the Site are
available in background correspondence files. In addition, a
database compiled from previous Site investigations is
available for the Site. These information sources have
identified that the chemical substances on Site include or
may potentially include those shown on <'flJ~~IO~~-f?VERS & ASSOCIATES

Several identified compounds including PCBs,
trichloroethylene, benzene and methylene chloride are
suspected carcinogens.
Acceptable exposure levels in air have been
established by the American Conference of Governmental
Industrial Hygienists (ACGIH). The eight hour time weighted
average (TWA) threshold limit values (TLV) established for
these compounds are presented in the Site-specific Health and
Safety Plan. The air monitoring and respiratory protection
programs will be designed around these TLVs.
C.2.3 BASIS
The Occupational Safety and Health
Administration (OSHA) Standards and Regulations contained in
Title 29, Code of Federal Regulations, Parts 1910 and 1926
(29 CFR 1910 and 1926) including the amended sections in
29 CFR 1910.120 and current TLVs as provided by the ACGIH
provide the basi~ for this Health and Safety Plan. Some of
the specifications within this section are in addition to
OSHA regulations and reflect the positions of the United
States ~nvironmental Protection Agency (USEPA), the National
Institute for Occupational Safety and Health (NIOSH) and the
United States Coast Guard (USCG) regarding procedures
required to ensure safe operations at hazardous waste sites. E

iv) effect of personal protective equipment and workload,
v) the various types of heat disorders and their
associated symptoms, and
vi) heat stress program -acclimatization, monitoring,
work/rest regimen, and fluid intake (balanced
electrolytic fluids).
This training will be conducted at the time
of the initial training.
Monitoring will be initiated when the ambient
air temperature is 70°F. The monitoring frequency will
depend upon the temperature and the type of protective
clothing worn. As the temperature increases, the monitoring
will become more frequent. Also, if an employee is wearing
impermeable protective clothing, the frequency of monitoring
will increase. For example, at 72.5°F (adjusted
ternperature)l and wearing an impermeable suit, an employee
will be monitored after every 120 minutes of work. If the
temperature increaies to 87.5°F (adjusted temperatuie), the
workers will be monitored after every 60 minutes of work.

3) body water loss (if practicable).
The heart rate will be determined for
30 seconds as soon as practicable during the rest period. If
this heart rate exceeds 110 beats per minute, the next work
cycle will be shortened by one third.
The oral temperature will also be taken at
the end of the work period. If the oral temperature exceeds
99.6'F, then the next work cycle will be shortened by one
third.
If the heat stress conditions become severe,
then the Site Safety Officer will recommend that body water
loss be determined. The employee will be weighed, and the
total body water loss will be kept below 1.5 percent body
weight loss in a work day.

If the air temperature is over 70°F, Heat Stress Monitoring may be implemented
as required. To monitor the worker, measure:
a. Heart Rate (while resting) -Count the radial pulse for 30 seconds as soon as
practicable during the rest period. If this heart rate exceeds 110 beats per
minute, the heat and work stress is assumed to be above acceptable values.
The work schedule should be reviewed.
b. oral temperature -Use a clinical thermometer (3 mins. under the tongue). at
the end of the work cycle. (Before drinking any fluid).
c.
If oral temperature exceeds 99.6°F (37.S"C), the work schedule should be
reviewed.
ROTE: Do not permit worker to wear semi-permeable or impermeable garments
when his/her core temperature exceeds 100.6°F (38°C).
Body Water Loss~ Measure weight on a scale at the beginning and end
day to determine if enough fluids are taken to prevent dehydration.
water loss should not exceed 1 .5 percent total body weight loss in a
day.

The Data Management Plan (DMP) presented
herein will identify procedures to be employed for managing
all information, reports and correspondence (documents)
associated with the Remedial Investigation and Feasibility
Study (RI/FS) to be conducted at the Jadco-Hughes Site (Site)
in Gaston County, North Carolina. These documents may be
used as possible evidence in any court proceedings and as the
basis upon which government officials will make decisions
regarding the protection of human health and the environment.
Therefore, these documents must be readily accessible and the
integrity and accuracy of these documents must be maintained.
This may be achieved by restricting access to the materials
and implementing data management procedures.
The DMP is comprised of two separate tasks
which are:
i )
ii)
data management; and
document control.
The data management task consists of
procedures used to handle and safeguard all data generated by
field and laboratory programs. The task of document control
involves implementing procedures to physically track all
documents associated with the RI/FS. These two tasks will be
expanded upon in the following sections.

E.2 DATA MANAGEMENT
Revision No: 0
Date: 05/31/88
Page: 2
Data generated from the field and analytical
programs will form the basis upon which all decisions
regarding remediation.of the Site will be based. Submittal A
-Site Investigation Plan, and Submittal B -Quality
Assurance Project Plan, present procedures relating to the
collection and analysis of samples. The data management task
of the DMP presents procedures relating to recording and
retrieval of all the field and laboratory data generated.
For ease of discussion, the field and laboratory data can be
categorized as follows:
i ) field data;
ii) laboratory analytical data; and
iii) quality assurance/quality control data.
These three categories of data and security procedures will
be discussed in the following sections.
E.2.1 Management ot Field Data
Accurate and comprehensive recording of field
operations will be achieved through the use of field
logbooks, cameras, tape recording devices and computers.

E.2.1.1 Field Logbooks
Revision No: 0
Date: 05/31/88
Page: 3
The field logbook is the primary means of
recording Site-related information. Generally, a bound
document, the field logbook is used to record all pertinent
Site data such as the following:
i) general field observations;
ii) field measurements and observations;
iii) sample location and corresponding sample number;
iv) relevant comments pertaining to the samples collected;
v) weather conditions;
vi) a listing of all personnel involved in Site-related
activities; and
vii) an accurate log of all telephone conversations and Site
meetings.
The field books generated will be numbered
consecutively and maintained in a CRA file where they are not
subject to potential damage or tampering.
E.2.1.2 Still Photographs and Video Film
Still photographs and video documentation
provide a means of visually recording Site conditions and
operations.

properly documented, catalogued and stored.
shall consist of the following:
i) identification of Site and project;
Document at ion
ii) identification of the area and/or activity
photographed;
iii) date and time of photograph;
iv) photographer's name;
v) weather conditions; and
vi) project number.
Cataloging of photographs and video films
shall be done in a manner that ensures ease of accessibility.
Storage of the photographs and video films shall be in a
location where they are not subject to damage or tampering.
E.2.1.3 Audio Cassette Recordings
On occasion, conditions may exist which will
prevent the use of field logbooks. At such times only, an
audio cassette tape recorder shall be used. Information
recorded on the cassette will be ~ranscrib~d into the field
logbook within one week of making the recording. The
recorded cassette then will be consecutively numbered, logged

and stored. The tapes will be logged as to the date and
purpose of the recording. Provisions will be made to store
the tapes so that they are protected from magnetic fields,
temperature extremes, reuse and tampering.
E.2.1.4 Computer Diskettes
At this time, it is envisaged that all
analytical and field survey data will be compiled on 5 1/4
floppy discs. In all cases where Site data is stored on
discs, a backup copy of each computer diskette will be
maintained. Each computer diskette will be consecutively
numbered, identified as a primary or backup diskette, and
identified as to the contents. The computer diskettes will
be cataloged and stored as per the audio cassette tapes.
Backup diskettes will be stored separately from primary
diskettes.
E.2.2 MANAGEMENT OF LABORATORY ANALYTICAL DATA
Chain-of-custody protocols will be used to
transport the samples to the contract laboratory and to track
the samples during the analytical program, as discussed in
Submittal A -Site Investigation Plan and Submittal B -
Quality Assurance Project Plan. Copies of the generated

chain-of-custody forms will be maintained by both the
contract laboratory and CRA.
The contract laboratory will provide the data
on a computer diskette in addition to the hard copy print.
The computer diskette provided by the contract laboratory
will be numbered, cataloged and stored as discussed in
Section F.2.1.4.
The contract laboratory will maintain the
integrity of their database through their own internal
security procedures.
E.2.3 DATA VALIDATION
Validation of the data will be performed in
accordance with the quality assurance/quality control (QA/QC)
program as detailed in Submittal B -Quality Assurance
Project Plan. Laboratory supervisory personnel and CRA's
QA/QC officer will conduct the data validation.
The data will be manually screened as well to
isolate any spurious data not detected by the QA/QC program.
