1.0 INTRODUCTION
Revision No: O
Date: 8/29/86
The purpose of this Quality Assurance Project Plan (QAPP) is to document the
procedures that will be undertaken to ensure the precision, accuracy, and
completeness of the data gathered during the remedial investigation (RI) of
the National Starch and Chemical Corporation (NSCC) Cedar Springs Road site in
Salisbury, North Carolina by IT Corporation (IT).
This QAPP has been prepared to document the measures that will be undertaken
by IT and its subcontractors so the work performed will be of proper quality
to accomplish project objectives and will be responsive to requirements of the
U.S. Environmental Protection Agency (USEPA). The plan addresses:
The QA (quality assurance) objectives of the project
Specific QA and QC (quality control) procedures that will be
implemented to achieve these objectives
Staff organization and responsibility.
The requirements of the USEPA with regard to QA focus on the acquisition of
environmental data of known and acceptable quality. Other aspects of the
project, such as engineering analysis and report preparation, will be
controlled by the internal requirements of !T's Quality Assurance Program.
The program is documented in the IT Engineering Quality Assurance Manual. Tfie
policies and procedures specified in the manual define acceptable practices to
be employed by personnel engaged in any particular project.
The IT Engin.eering Quality Assurance Manual and Southeast Region Quality
Assurance Procedures Manual are composed of controlled documents which are
considered proprietary information, but applicable documents for this project
can be supplied to regulatory agencies.
1. 1 PROJECT DESCRIPTION
The NSCC Ced_ar Springs Road Plant was built beginning in December of 1970.
Initially it was operated as Proctor Chemical, a subsidiary of NSCC. The
merger into NSCC took place on January 1, 1983. The plant produces chemicals

for use in textile and furniture industries. Specialty chemicals are also
produced.
The NSCC Cedar Springs Road Plant is located on approximately 465 acres within
the city limits of Salisbury in Rowan County, North Carolina. A vicinity map
is presented on Figure 1. A location map is shown on Figure 2.
The site is situated on saprolitic soils formed in place on top of decomposing
_dioritic/gabbroic rocks of Paleozoic age. Near-surface soils are generally
silty clays which extend down to approximately 10 feet. Subsurface soils are
predominately silty sands and sandy silts, extending down to the felsic
bedrock. Depth to bedrock was noted in the 1977 exploratory test drilling as
being 40 feet below the ground surface along the eastern side of the waste
burial area.
The water table beneath the trench area varies from 12 to 35 feet below the
ground surface, fluctuating seasonally. Direction of flow generally follows
the topographic relief, with shallower water tables appearing along the slopes
and deeper water tables existing at the top of the hill immediately east of
the trench area. Subsequently, the direction of flow within this unconfined
aquifer is generally southwesterly, following the surface gradient toward a
tributary of Grants Creek which lies west of the site. Some ground water
discharge is occurring along the gullies and streams dissecting the hilly
terrain. These springs are probably situated near the saprolite/ bedrock
interface.
Surface waters on and directly adjacent to the trench area flow into Grants
Creek via an unnamed intermittent stream. Directional flow of the overland
runoff west of the trench area is southwesterly along several gullies which
dissect the hill and then westward along the intermittent stream. Areas east
of the trench area exhibit a northeasterly overland flow direction into
another intermittent stream which flows northwesterly into Grants Creek.
The site includes chemical manufacturing facilities, a wastewater treatment
system, treatment lagoons, and approximately two acres of trenches used to
bury 350,000 gallons of D002 waste. The wastes were buried in 3-foot wide by

1O-foot deep trenches during 1971 to 1978. When percolation in one trench
decreased, the trench was filled with excavated soil and a similar trench was
dug a few feet away. This procedure continued until approximately two acres
of land was trenched.
The wastes buried on site include salt brines, sulfuric acid solutions,
sulfonating fats and oils, with deminimus concentrations of heavy metals such
as lead, chromium, zinc, and some organic constituents including triallyl,
ethers, 1,2-dichloroethane, 1,2-dichloropropane, 2-methyl-1-pentanol,
methanol, toluene, and xylene.
In 1977 the North Carolina Department of Environmental Management conducted a
survey of the site and drilled test borings to determine if contamination had
occurred. The analysis of the ground water samples showed higher than normal
background levels of various contaminants, including chloride, sodium, iron,
and high levels for specific conductance. It was concluded that the ground
water was contaminated, with potential contamination of surface waters
indicated.
NSCC conducted additional sampling of six on-site monitoring wells, installed
by NSCC in 1976, in September of 1984. The sampling phase analysis showed
that organic contamination of Well No. 1, which was located in the middle of
the tr~nch area, included toluene, xylenes, 1,2-dichloroethane, 1,2-
dichloropropane, allyl alcohol, allyl ether, and triethylphosphate.
Concentration levels of these organics ranged from 0.8 to more than 180 parts
per million (ppm). The analysis also indicated some organic contamination in
Wells No. 2 and 3. Both wells are located to the west of the trench area.
The well located to the south of the trench area, Well No. 4, indicated very
little or no contamination; but it should be noted that this well is usually
dry. There was no evidence of any organic contamination in Wells No. 5 and 6,
both located east of the trench area.

Five residential wells located within two miles of the Cedar Springs Road
Plant were sampled. Analytical results showed no evidence of volatile organic
compounds or priority pollutants.
Well No. 5 was installed immediately downgradient of two holding lagoons
located south of the main plant building. During the summer of 1984, roughly
2000 cubic yards of contaminated soil was removed from beneath these lagoons
as they were being lined with concrete. The initial scope of the RI/FS is
being expanded to address potential subsurface contamination around these
lagoons.
In July 1986 IT entered into an agreement with NSCC to conduct a RI/FS of the
NSCC Cedar Springs Road site, Salisbury, North Carolina. IT will develop and
evaluate remedial action alternatives to mitigate serious environmental
problems evident at the site, prepare risk assessments of these alternatives,
recommend the most appropriate and cost-effective remedial action alternative,
and develop a conceptual design for that alternative.
1.2 PROJECT OBJECTIVES
The objectives of the Remedial Investigation (RI) for the Cedar Springs Road
site are to collect the data needed to assess site hazards and evaluate
alternatives in the Feasibility Study (FS). Tasks that will be undertaken
include:
' Identifying specific contaminants that pose a danger to the public or
the environment
Determining the nature and extent of contamination on the project
site including surface waters, ground water, and sediments
Identifying pathways of contaminant migration from the site as well
as the impact of contaminants on potential receptors
• Determining whether the site poses an imminent hazard to the public
health or the environment
• Determining and describing on-site physical features that could
affect migration of contaminants, methods of containment, or methods
of remedial action cleanup
Developing and evaluating the feasibility of various remedial action
alternatives

Preparing a conceptual design of the selected remedial action
alternative.
These objectives will be accomplished through an assessment of the existing
conditions by using available data and the results of the remedial
investigation. The remedial investigation will include: mapping the site and
surrounding areas; a geophysical survey; a hydrogeologic investigation;
geochemical testing of the shallow saturated media; and environmental sampling
and testing of ground water, surface water, soil, and sediment.
The site investigation phase for the RI at the Cedar Springs Road site will
consist of the following:
Fourteen shallow monitoring wells will.be installed: five along the
western portion of the trench area, four along the eastern side, two
inside the trench area, and three surrounding the lagoon area. In
addition, three deep bedrock wells will be installed north and west
at the trench area. Exact placement of these wells will be
determined after the geophysical survey has delineated the nature of
the conductive/ resistive properties of the phreatic zone. Total
depth of each shallow well is not expected to exceed 45 feet, with
anticipated water.table depths varying from 10 to 35 feet beneath the
ground surface. Total depth of each deep well will be approximately
100 feet deep. A two-phase ground water sampling and analysis
program will be performed to determine the degree and extent of
ground water contamination in the vicinity of the Cedar Springs Road
plant.
Six sediment samples and four surface water samples will be collected
from six locations on or adjacent to the site. The surface water
samples will be grab samples; sediment samples will be taken from the
top one inch of sediment. The exact locations of these samples will
be determined after a thorough survey of the site is conducted.
• Five boreholes will be placed in the trench area. Sampling will be
conducted in the unsaturated zone at 3-foot centers using a split-
spoon sampler. Samples from each borehole will be composited.
All water samples will be

3.0 QUALITY ASSURANCE OBJECTIVES
Revision No: O
Date: 8/29/86
This project will be performed in conformance with !T's QA Program
requirements, and applicable federal, state, and contract requirements.
Project QA objectives are as follows:
The scientific data generated will be of sufficient or greater
quality to stand up to scientific and legal scrutiny
• The data will be gathered or developed in accordance with procedures
appropriate for the intended use of the data
• The data will be of known and acceptable precision, accuracy, and
completeness.
This QAPP has been prepared in direct response to these goals. This plan
describes the QA Program to be implemented and the QC procedures to be
followed by IT and its subcontractors during the course of the project. These
procedures will:
Maintain the necessary level of quality of each aspect of the
analytical program by providing the appropriate level of verification
testing, checking, and statistical analysis of laboratory program
procedures
Assist in the early recognition of factors which may adversely affect
the quality of data, and provide for the implementation of procedures
to correct these adverse effects
Enhance the utility of all data produced by the laboratory for
decision-making purposes by requiring sufficient documentation of the
testing process. This provides information on the limitations of the
analytical results.
In this regard, the QAPP will provide for the definition and evaluation of the
following parameters:
Detection limits
Data precision
Data accuracy
Completeness of data.

3.1 DETECTION LIMITS
Revision No: O
Date: 8/29/86
The detection limit for a given parameter is defined as the minimum
concentration that can be determined from an instrument signal that is three
times the background noise. Tables 1a-1d provide a listing of the estimated
detection limits for pollutants.
3.2 DATA PRECISION AND EVALUATION
Precision is a measure of the mutual agreement among individual measurements
of the same property, usually under prescribed similar conditions. Relative
Percent Difference (RPD) will be used to define the precision between
replicate analyses. RPD is defined in Section 12.0. The precision objectives
for the HSL analyses will be the same as those estimated by the methodology.
Non-homogenous constituents in the soil samples may produce poor precision in
the results. QA objectives are presented in Table 2.
3.3 DATA ACCURACY AND EVALUATION
Accuracy is defined as the degree of agreement of a measurement with an
accepted reference or true value. The percent recovery (%R), determined by
sample spiking, is typically used to define the accuracy of an analytical
procedure. Percent r.ecovery is defined in Section 12.0. The accuracy
objectives for the HSL analyses will be the same as those established by the
USEPA for its Contract Laboratory Program (CLP). Non-homogenous constituents
in the soil samples may also affect the percent recovery results, if the
native analytes in the spiked and unspiked aliquots have different
concentrations. QA objectives are presented in Table 2.
3.4 COMPLETENESS OF DATA
Completeness is a measure of the amount of valid data obtained from a
measurement system compared to the amount that was expected to be obtained
under correct normal conditions. Over 90 percent of all data obtained on this
project should be valid based upon evaluation of the QC data. QA objectives
are presented in Table 2.
3.5 COMPARABILITY
In order to assure that the data will be comparable to similar data sets, only
EPA-approved analytical methods will be used. For HSL compounds, these

4.0 SAMPLING PROCEDURES
Revision No: 0
Date: 8/29/86
Any sample obtained during the course of a field investigation should be
representative of the site and free of contaminants from sources other than
the immediate environment being sampled. The equipment and the techniques
that will be employed to obtain representative, unbiased samples will be in
accordance with IT Standard Operating Procedures as discussed in Section 5.0
of !T's Engineering Quality Assurance Manual. Section 5.0 of the IT
Engineering Quality Assurance Manual provides information on the advancement
of geotechnical borings and geotechnical sampling and will be used to
supplement this plan as necessary.
Information obtained from site exploration activities will be recorded and
documented in accordance with SR QAP 9.0 of the IT Southeast Engineering
Quality Assurance Manual. Required documentation of field investigation and
testing includes a daily log of project.activities, appropriate subsurface
logs, and test data forms. Examples of this documentation are shown in
rigures 4 and 5.
The Sampling Plan (Appendix A) describes the numbers and types of samples to
be collected; sampling equipment, procedures, and locations; sample
containers; methods of sample preservation; decontamination procedures;
shipping and packaging methods; analytical tests to be performed; sampling
personnel; and sampling schedule.
To reduce the possibility of cross-contaminating samples, all tools, sampling
equipment, and surfaces of measuring instruments will be throughly
decontaminated between each use. The general decontamination procedures that
will be observed are as follows:
Wash with detergent trisodium phosphate (TSP) and water
Rinse with hot tap water
Rinse with deionized water
Rinse with isopropyl alcohol
Air dry.

5.0 SAMPLE CUSTODY
5. 1 CHAIN-OF-CUSTODY PROCEDURES
Revision No: 0
Date: 8/29/86
Chain-of-custody procedures are intended to document sample possession from
the time of collection to disposal, in accordance with federal guidelines. A
copy of !T's chain-of-custody record form is included in Figure 6. For·the
purpose of these procedures, a sample is considered in custody if it is:
• In one's actual possession
In view, after being in physical possession
Locked so that no one can tamper with it, after having been in
physical custody
In a secured area, restricted to authorized personnel.
These procedures will be followed for all samples subject to chemical analysis
for this project:
Sample containers will be sealed in the field. Any samples that do
not arrive at the laboratory with seals intact will not be considered
to have been in valid custody. In the event that the laboratory
sample custodian judges the sample custody to be invalid (i.e.,
samples arrive with seals broken), nonconformance documentation will
be initiated. The project manager will then be notified. The
decision will be made by the project manager as to the fate of the
sample(s) in question. The sample(s) will either be processed ''as
is" with custody failure noted along with the analytical data, or
· rejected with resampling scheduled if necessary.
A chaln-of-custody record will be initiated in the field for each
sample. A copy of this record will accompany each sample.
Each time responsibility for custody of the sample changes, the new
custodian will sign the record and note the date.
Upon sample destruction or disposal, the custodian responsible for
the disposal will complete the chain-of-custody record, file a copy,
and send a copy to the PM or to his designated representative for
record keeping.
The custody of individual sample containers will be documented by
recording each container's identification on an appropriate chain-of-
custody form.

Analyses for each sample will be recorded on an IT Analytical
Ser.vices ( ITAS) Request-for-Analysis form (see Figure 7).
The following documentation will supplement the chain-of-custody
record·s:
-Sample label on each sample
-Sample seal on each sample
-Field collection report
-Photographic records (wherever practical and to the extent
economically feasible)
Before sampling, all personnel involved will have received copies of
the chain-of-custody procedure.
SAMPLE LABELING
Sample labels must contain sufficient information to uniquely identify the
sample in the absence of other documentation. Labels will include as minimum:
Project number
Unique sample number
• Sample location
Sampling date and time
Individual collecting the sample
Preservation method employed.
The sample label will always be directly affixed to the sample container and
will always be completed using indelible ink. An example of the sample label
to be used in this project is presented in Figure 8.
In addition, IT custody seal tape will be used on each sample container to
prevent the unauthorized tampering or removal of each aliquot. This tape will
be affixed across the container lid in such a manner as to show visible
evidence of tearing when the lid is utlimately removed.

6.0 EQUIPMENT CALIBRATION
6. 1 GENERAL CALIBRATION PROCEDURES
Revision No: 0
Date: 8/29/86
All laboratory and field testing equipment used for analytical determinations
will be subject to periodic inspection and calibration. Equipment calibration
procedures will follow !T's Engineering Services QA procedure as outlined in
Section 5.5.
Measuring and test equipment and reference standards will be calibrated at
prescribed intervals and/or before use. Frequency will be based on the type
of equipment, inherent stability, manufacturer's recommendations, values given
in national standards, intended use, and experience. A summary of calibration
requirements for certain laboratory instruments is included in Table 3.
Calibrated equipment shall be uniquely identified by using either the
manufacturer's serial number or other means. · A label with the identification
number and the date when the.next calibration is due will be attached to the
equipment. If this is not possible, records traceable to the equipment will
be readily available for reference.
Scheduled periodic calibration of testing equipment does not relieve field or
laboratory personnel of the responsibility of employing properly functioning
equipment. If an individual suspects an equipment malfunction, he shall
remove the device from service, tag it so it is not inadvertently used, and
notify the PM so that recalibration can be performed or substitute equipment
can be obtained.
6.2 CALIBRATION FAILURES
Equipment that fails calibration or becomes inoperable during use will be
removed from service and either segregated to prevent inadvertent use, or
tagged to indicate it is out of calibration. Such equipment will be repaired
and recalibrated or replaced as appropriate.

9.0 QUALITY CONTROL PROCEDURES
9. 1 FIELD QUALITY CONTROL PROCEDURES
Revision No: O
Date: 8/29/86
To check the quality of data from field sampling efforts, blank (water) and
duplicate samples will be submitted to !T's Analytical Laboratory. Blank
samples will be analyzed to check for container contamination. Duplicate
samples will be analyzed to check for sampling and analytical error causing
data scatter. The confidence limits and percent level of uncertainty will be
calculated and reported in the RI report. One duplicate will be prepared for
every 20 samples collected and one blank will be prepared for every 20 samples
(including duplicates) submitted for analysis.
Water used for the analysis of trace metals will be purified by reverse
osmosis/deionization to not less than 10 Mn cm. Water for organic
determinations will be deionized and then further purified with activated
carbon.
Standard ITAS sampling equipment and procedures will be used for blank
sampling as described in the Project Operations Plan. All blank (water) and
duplicate samples will be treated as separate samples for identification,
logging, and shipping.
9.2 LABORATORY QUALITY CONTROL PROCEDURES
9.2. 1 Volatile Organics
Samples for volatile organics analysis will be analyzed according to current
CLP procedures. An initial calibration curve will be prepared using a mixture
of standards at five different concentrations and a mixture of three internal
standards. Each GC/MS tune will be verified every 12 hours to ensure that its
performance on bromofluorobenzene or DFTPP meets the applicable USEPA
criteria. The continuous calibration is also verified prior to sample
analysis by re-analysis of the midrange standard.
All standards, method blanks, and samples will be spiked before analysis with
surrogate standards as specified in CLP procedures. Surrogate standards are

defined as Non-Priority Pollutant compounds used to monitor the %R
efficiencies of the analytical procedures on a sample-by-sample basis.
Samples exhibiting surrogate standard responses outside the established
control limits will be re-analyzed.
A sample may be ·re-extracted, in accordance with CLP protocol, after the
holding time has elapsed in order to resolve a QC problem. It may turn out
that low recoveries are a sample matrix problem and not an analytical
problem. In this event, both analyses will be reported.
Prior to re-extraction, however, several items are checked when a recovery is
in question or out of specifications. It may only require re-analysis and not
re-extraction. In this case holding times would not be a problem.
In the unlikely event that the QC problem is not resolved by re-extraction
after the holding time assessment of existing data would be performed. The
project manager would determine if re-sampling is required.
At least one method blank for every 20 samples will be purged and analyzed for
volatile organic compounds. Volatile organics analysis requires a method
blank consisting of 5 milliliters of organic free water spiked with the
appropriate surrogate standards. Results of the method blank analysis will be
maintained with the corresponding sample analyses.
Matrix spike and matrix spike duplicate analyses will be performed on one of
every 20 samples per matrix analyzed. A separate aliquot of the sample will
be spiked with the appropriate HSL compounds before purging the sample. The
percent recoveries for the respective compounds will then be calculated.
Should the %R values fall outside the appropriate QC limits, the other QC
parameters will be evaluated to determine whether an error in spiking occurred
or whether the entire set of samples requires re-purging and analysis.
The relative percent error for each parameter will then be calculated from
these matrix spike and matrix spike duplicate analyses. Should the average
relative percent error fall outside the appropriate QC limits, the other QC
parameters will be evaluated to determine whether the duplicate sample should

be re-purged and analyzed or whether the entire set of samples must be re-
purged and analyzed.
9.2.2 Extractable Organics
Samples for extractable organics analysis will be analyzed according to
current CLP procedures. An initial calibration curve will be prepared using a
mixture of standards at five different concentrations and a mixture of six
internal standards. Each GC/MS tune will be verified every 12 hours to ensure
that its performance on bromofluorobenzene or DFTPP meets the applicable USEPA
criteria. The continuous calibration is also verified prior to sample
analysis by re-analysis of the midrange standard.
All s'tandards, method blanks, and samples will be spiked before analysis with
surrogate standards as specified in CLP procedures. Surrogate standards are
defined as Non-Priority Pollutant compounds used to monitor the %R
efficiencies of the analytical procedures on a sample-by-sample basis.
Samples exhibiting surrogate standard responses outside the established
control limits will be re-analyzed.
At least one method blank for every 20 samples will be extracted and analyzed
for base neutral/acid extractable compounds. Extractable organics analysis
requires a method blank consisting of 1 liter of organic free water spiked
with the appropriate surrogate standards. Results of the method blank
analysis will be maintained with the corresponding sample analyses.
Matrix spike and matrix spike duplicate analyses will be performed on one of
every 20 samples per matrix analyzed. A separate aliquot of the sample will
be spiked with the appropriate HSL compounds before extracting the sample.
The percent recoveries for the respective compounds will then be calculated.
Should the %R values fall outside the appropriate QC limits, the other QC
parameters will be evaluated to determine whether an error in spiking occurred
or whether the entire set of samples requires re-extraction and analysis.
The relative percent error for each parameter will then be calculated from
these matrix spike and matrix spike duplicate analyses. Should the average
relative percent error fall outside the appropriate QC limits, the other QC

parameters will be evaluated to determine whether the duplicate sample should
be re-extracted and analyzed or whether the entire set of samples must be re-
extracted and analyzed.
9.2.3 Pesticides/PCBs
Samples for pesticide/pcb analysis will be analyzed according to current CLP
procedures.
Qualifying the Column
Each time a new column is installed into a specific gas chromatograph, or the
chromatographic conditions are changed, i.e., change of flow rates, detectors,
electronics, etc., three different concentration standards are analyzed to
determine calibration factors and linearity specific to these conditions.
This process occurs in a 24 hour period. Calibration factors are then
calculated for each pesticide and PCB. If the linearity for the calibration
factors is~ 10 percent, the samples analyzed on that gas chromatograph can be
directly quantitated from the range. If the linearity is~ 10 percent, a
calibration curve is generated for each compound to be qualified.
Standard and QC Solutions
Once the column has been qualified, a 72 hour evaluation run is performed with
3 concentration standards. Retention time windows are developed for each
pesticide and PCB from the three concentration standards. The range is
determined by calculating 3 times the standard deviation of the three
retention times for the individual compounds, and applying it to the daily
retention time for that same component.
Percent difference in retention time shift for the spiked surrogate is
calculated. A 2 percent difference in retention time is allowable. Percent
recovery of the surrogate is also .calculated to determine accuracy and
precision of all analytical steps involved.
Component breakdown is monitored periodically by injecting a standard
containing DDT and Endrin and looking for its breakdown products: ODD, ODE
for the former and Endrin Aldehyde and Enfrin Ketone, for the latter.

Once the gas chromatograph is qualified, daily evaluation standards are
injected before any samples are injected. After a specified number of sample
evaluation mixes and/or standards are injected to establish daily retention
times and linearity for all PCB's and pesticides in question. Quality control
standards are injected at specific intervals, at least every 20 samples.
Additional quality control standards are run to measure pesticide recovery and
reproducibility of analysis.
At least one method blank for every 20 samples will be extracted and analyzed
for pesticides and PCB's. Pesticides/PCB analysis requires a method blank
consisting of 1 liter of organic free water spiked with the appropriate
surrogate standards. Results of the method blank analysis will be maintained
with the corresponding sample analyses.
Matrix spike and matrix spike duplicate analyses will be performed one of
every 20 samples per matrix type analyzed. A separate aliquot of the sample
will be spiked with the appropriate HSL compounds before extracting the
sample. The percent recoveries for the respective compounds will then be
calculated. Should the %R values fall outside the appropriate QC limits, the
other QC parameters will be evaluated to determine whether an error is spiking
occurred or whether the entire set of samples required re-extraction .and
analysis.
The relative percent error for each parameter will then be calculated from
these matrix spike and matrix spike duplicate analyses. Should the average
relative percent error fall outside the appropriate QC limits, the other QC
parameters will be evaluated to determine whether the duplicate sample should
be re-extracted and analyzed or whether the entire set of samples must be re-
extracted and analyzed.
9.2.4 Metals and Miscellaneous
As for the organics, at least one method blank, consisting of reagent water
and all reagents used in the method, will be analyzed for every 20 samples.

12.0 SPECIFIC ROUTINE PROCEDURES USED TO ASSESS DATA PRECISION,
ACCURACY, AND COMPLETENESS
The following discussion describes the procedures that will be employed to
evaluate the precision, accuracy, and completeness of the chemical test data
generated during the investigation. Accuracy is assessed by splitting a
sample into two portions, spiking, (i.e., adding a known quantity of the
constituents of interest to one of the portions), and then analyzing both
portions for these parameters. The difference in the concentration levels of
the constitutents of interest should be equal to the quantity of the spike
added to one of the two portions. The actual %R is calculated as follows:
%R = WC/6C 2 X 100
where 6C is the measured concentration increase due to spiking and 6Cs is the
known increase due to the spike. One hundred %R is equivalent to 100 percent
accuracy. The coefficient of variation (Cv) of the %R values is calculated as
follows:
SD Cv = APR X 100
SD is the standard deviation of the percent recoveries for the various spiked
constitutents and APR is the average or mean %R.
Precision is assessed by conducting separate analyses of the duplicate
samples. A measure of the agreement in the reported values for the two
portions i~ obtained by calculating the relative percent difference (RPO) in
the concentration levels of each constituent, where
RPO. = l
A. 8. l - l
(Ai+ Bi)
2
X 100
and Ai ~nd Bi are the concentrations of the ith constituent.
The evaluation of the test data will be based in part on criteria adopted by
the Sample Management Office of the USEPA. These criteria provide a means of

In addition to evaluating each set of data for accura.cy and precision, an
assessment will also be made of the completeness of the data. This will
involve computing the fraction of the reported values that remain valid after
the sampling procedures have been reviewed and the results have been assessed
for precision and accuracy. The QA objectives for the investigation relativ(
to precision, accuracy, and completeness are described in Section 3.
For these analyses conducted by EPA CLP protocol, current acceptance criteria
established by EPA will be used. These include recoveries of surrogate
compounds added to each sample and recoveries of HSL compounds added to the
matrix spike and matrix spike duplicate samples.

1.0 INTRODUCTION
Remedial Investigation (RI) activities conducted by IT Corporation (IT) at the
National Starch and Chemical Corporation Cedar Springs site, Salisbury, North
Carolina will include the following activities noted below.
Seventeen monitoring wells will be installed, and ground water sampling will
be conducted in two phases. The first phase will occur after it has been
determined that the wells are stabilized. The second phase will occur during
the ~ext quarter with samples being collected from all 17 wells. Samples will
be analyzed for temperature, pH, specific conductance, TDS, chloride,
volatiles, semi-volatiles (base neutral/acid extractables), pesticides, PCBs,
cyanides, metals, and phenols. Four surface water samples will be collected
and analyzed for the above discussed parameters and total suspended solids
(TSS). Six sediment samples will be collected from drainage paths west and
southwest of the landfill area and analyzed for volatiles, semi-volatiles
(base neutral/acid extractables), pesticides, PCBs, cyanides, and phenols.
Five composited borehole samples will be collected from inside the trench
area. These soils will be analyzed for the same parameters as the sediment
samples. Three subsurface samples will be collected from an area near
existing Well No. 6 for geochemical analysis. This analysis will include
certain geotechnical parameters and a column test to determine the attenuative
and adsorptive properties of the saturated shallow media.
In the following sections of this sampling plan, information is presented on·
the proposed sampling locations and numbering system; drilling and sampling
procedures; quality assurance/quality control (QA/QC) sampling procedures,
sample handling and analyses; decontamination procedures; field documentation
procedures; organization, responsibilities, and training of the field team;
and the schedule for field activities.

2.0 SAMPLING LOCATIONS, LABELING, AND NUMBERING SYSTEMS
2. 1 LOCATIONS
Tentative boring and monitoring well locations are shown in Figure 1. Exact
boring and monitoring well locations will be determined in the field by either
the Project Manager, the Project Hydrogeologist, or both.
2.2 LABELING
The sample containers will be labeled before being filled at each sampling
location. The sample labels for sediments, surface water, and ground water
samples show the project number, sample number, sample location, date, time of
sampling, and sampler's initials. The label will be filled out with
waterproof ink or marker.
2.3 SAMPLE NUMBERING SYSTEM
A sample numbering system will be used to identify each sample taken during
the Cedar Springs Road site sampling program. This numbering system will
provide a tracking procedure to allow retrieval of information about a
particular sample and provide each sample with a unique number. The sample
identification numbering system is described below:
Each sampling type collected during the sampling program will be
identified by a two-digit code:
-Sediment (SE)
-Ground Water (GW)
-Surface Water (SW)
-Borehole (SH).
This will be followed by a two-digit code indicating location.
A one-digit number will be used to consecutively number sequential
samples taken at a sampling site.
Examples of sample numbers are:
• GW-01-1 -Ground water sample, Location 01, Sample 1
SE-(01-05)-1 -Sediment sample, composite of Locations 01 through 05,
Sample 1.

3.0 DRILLING AND SAMPLING PROCEDURES
The purpose of this task is to characterize the near surface site geology and
the horizontal and vertical extent of contamination at the site. The
exploration is planned to consist of the installation of 17 monitoring wells
at the site. A qualified hydrogeologist will develop boring logs from the
drilling and coordinate all field activities.
3. 1 MONITORING WELLS/GROUND WATER
Seventeen monitoring wells will be installed in the vicinity of the trench
area and the lagoon area. These wells will include 14 shallow saprolitic
aquifer monitoring wells and three deep bedrock aquifer monitoring wells.
Figure 1 shows the well locations.
The shallow wells will be screened in ·the uppermost water-bearing intervals of
the saprolitic sequence, which varies in thickness from 10 to 40 feet beneath
the site. It is assumed that the ground water flow within this shallow zone
follows the surface topographic relief, with the flow being southwest at the
trench area and east beneath the lagoons. The total depth of each well is not
expected to exceed 45 feet, with anticipated water table depths varying from
10 to 35 feet beneath the ground surface. Each shallow well will be
constructed with 10-foot screens.
A total of eleven shallow wells will be installed in the vicinity of the
' trench area: five along the western portion of the trenches, four along the
eastern boundary, and two inside the trench area. The locations east of the
trenches will be northwest of the northeast corner (Well NS-01), northeast of
the trench area midpoint (NS-02), northeast of the southeast corner (NS-03),
and south of the southeast corner (NS-04). Wells NS-02, -03, and -04 are
located along the expected ground water flow lines and are intended to
determine if ground water contamination has occurred beyond the ground water
divide thought to exist east of the trench area. Well NS-01, an upgradient
well, is not situated along any suspected ground water flow line leaving the
trench area. The well locations west of the trench area will be southwest of
the aeration basin well (NS-05), west· of the southwest corner (NS-06),
northwest of existing Well No. 2 (NS-07), west of existing Well No. 1 (NS-08),

and north of the northwest corner (NS-09). Wells NS-05 through NS-08 are
located along expected ground water flow lines directly downgradient of the
trench area. Well NS-09 is located along a possible flow line emanating
toward the gully which runs northwest of the trench area.
Two shallow wells will be installed inside the trench area to characterize the
ground water immediately in and adjacent to the disposal trenches. Well NS-10
will be positioned in the upper middle section, north of existing well No. 1.
Well NS-11 will be located along the lower western side, southeast of existing
well No. 2.
Three shallow wells will be installed around the lagoon area. These locations
will include one upgradient well (NS-12), positioned west of the lagoon area,
and two downgradient wells (NS-13 and NS-14), positioned along the northeast
and southeast corners, respectively.
The three deep wells will be installed north, northwest, and west of the
trench area and will be screened in the upper water-bearing intervals of the
igneous bedrock and constructed with 20-foot screens. Total depth of each
deep well is not expected to exceed 100 feet. The wells will be located north
of the northeast corner (NS-15), west of existing Well No. 2 (NS-16), and
north of the northwest corner (NS-17). NS-15 will be topographically
upgradient of the trench area and will be installed adjacent to the background
well NS-01. NS-16 and NS-17 will be downgradient of the trench area and will
be installed beside NS-07 and NS-09 respectively. These three deep wells will
be clustered with shallow wells to provide an opportunity to check for
vertical migration of contaminants into the bedrock aquifer should
contamination be found in the shallow aquifer. This will be accomplished by
clustering wells NS-01/NS-15, NS-07/NS-16, and NS-09/NS-17.
The borehole for each shallow well will be drilled by using 6-inch diameter
hollow stem augers and will be drilled to the top of the igneous bedrock. If
bedrock is not encountered within the expected 45-foot depth, the well will be
completed at that depth or after a 10-fooc column of ground water has been
noted (whichever is deeper). Should the water table be at or near the
surface, the screens will be placed at least 1 foot below the ground and the

annulus filled with bentonite pellets to prevent surface runoff from entering
the well.
The deep wells will be drilled and rock-cored (NX) and over-reamed with an air
rotary rig and will be completed at the 100-foot depth, or whenever a 20-foot
coluinn of bedrock water is encountered (whichever is deeper). The desired
column of bedrock ground water will be determined by the supervising
hydrogeologist and will be derived from logging notes and visual observance.
Whenever a water-bearing interval in the bedrock is encountered, drilling will
continue for an additional 20 feet to achieve the desired depth.
The shallow wells will be constructed of 2-inch inside diameter, flush-joint,
threaded, stainless steel pipe with 10-foot screens. All screens will be
constructed of 0.02-inch slot-size stainless steel, fitted with a threaded
stainless steel bottom cap, and placed within each well at appropriate depths
to allow the inflow of water at and 1 foot above the water table for seasonal
fluctuations. A gravel pack will installed around and 1 foot above the screen
and topped with 2 feet of bentonite pellets. A bentonite/cement slurry will
then be placed by means of a tremie pipe from the top of the pellets to about
3 feet below the ground surface to seal the annulus. ,A 4-inch diameter
protective casing with locking cap will be installed, and the remainder of the
hole will be grouted with neat cement. Each riser will be fitted with a
slotted cap to permit the venting of gases and equilibration to atmospheric
conditions. A sloped cement apron wi'll be placed around the casing to prevent
runoff from entering the well.
The deep wells will be constructed in similar fashion, except that 2-inch PVC
riser will be used for the upper 50 to 60 feet interval. Additionally, an
outer PVC casing (approximately 8-inch diameter) will be installed and grouted
in place before bedrock drilling. This will seal off the shallow saprolitic
aquifer and will prevent any mixing of the upper shallow zone with the deeper
bedrock zone. A dedicated stainless steel/Teflon bladder pump system (Well
Wizard Model T-1200 with Purge Mizer Model 4200) will be installed in each
deep well for development, purging, and sampling purposes.

All wells will be fully developed by pumping or bailing until the fluid runs
clear. Dedicated Teflon bailees (bottom-filling; closed-top) will be used on
the shallow wells, and dedicated pumps will be used on the deep wells. Water
levels will be allowed to equilibrate over a ~uitable time. Measurements of
static water level will be taken with an electronic water-depth indicator to
the accuracy of 0. 1 foot. All development water will be sent through the
plant wastewater treatment system for disposal.
Each boring will be logged by the Project Hydrogeologist. This individual
will also provide continuous inspection of all drilling activities. The
boring log will include:
Heading information. Included will be the project number, boring number, personnel responsible for logging the hole, ground elevation and coordinates, and date started and completed

Decontamination procedures for the equipment used in the subsurface
investigation are outlined in Section 3.4.
The first phase of the ground water sampling will occur after it has been
determined that the wells are stabilized. The stabilization period will be
approximately four weeks. The second phase will occur during the next
quarter. Samples will be collected from all 17 newly installed monitoring
wells.
· Before sampling, each well will be properly purged to remove stagnant water
from the well casing and allow the collection of a representative ground water
sample. This will involve the removing of three-to-five well volumes from
each well, until the pH and conductivity stabilizes. It may be necessary to
purge lesser volumes from slowly recharging wells. Purging will be
accomplished by either bailing (shallow wells) or pumping (deep wells). All
purge water will be sent through the plant wastewater treatment system for
disposal.
After an acceptable volume of water has been purged from each shallow well,
ground water samples will be collected with closed-top, bottom filling,
dedicated Teflon~ bailers. Clean plastic sheeting will be placed on the
ground around each well to prevent contamination of sampling equipment in the
event any equipment is dropped or otherwise comes in contact with the
ground. New nylon cord will be used for each sample, then discarded. The
ground water will be poured from the bailer into a decontaminated, stainless
steel bucket. When a sufficient amount of water has been collected, it will
be thoroughly mixed with a Teflon or stainless steel spoon and poured into the
sample containers. Ground water samples will be collected from the deep wells
using the dedicated bladder pumps. As soon as pH, conductivity, and
temperature measurements have been stabilized during purging, the samples will
be collected from the tubing directly into the appropriate containers.
3.2 SEDIMENT/SURFACE WATER
Surface water and sediment samples are to be collected in pairs at all
sampling points unless otherwise specified. These points were selected to
enable the collection of representative samples along the drainage paths. See

Figure 1 for the sample location map. Surface water samples will be collected
first with sediment samples collected immediately afterward.
Proposed surface water and sediment sampling points will already have been
designated. A sampling site will be found where the water is well mixed. A
single grab sample will be taken at mid-depth at the center of the channel to
represent the entire cross-section. Sediment samples will also be collected
at the center of the channel. Direct dipping of the sample container into the
stream will be done to collect the surface water sample. The stream will be
waded to collect the water and sediment sample. The samples will be collected
by dipping the sample container into the stream while keeping the container
pointed upstream.
A decontaminated stainless steel bucket will be used to collect water samples
if the stream is not deep enough to allow direct dipping of the sample
container. In this case, water will be dipped from the stream using a small
Teflon container. Dipping will be done carefully to avoid turbulent
conditions in sample collection and transferal to the bucket. The bucket will
be rinsed twice with the sample water before the sample is collected.
Precautions will be taken to ensure that the sediment sample collected is
representative of the stream bed. The sediment sample will be collected by
scooping up the sediment with dedicated hand trowels. One person will wade
into the stream; and while facing upstream (into the current), scoop the
sample along the stream bottom in the upstream direction.
For sample splitting for duplicates or quality control measures, a sufficient
volume for all sample containers will be collected in a large glass, Teflon
(or equivalent) compositing jug and then, with mixing, be alternatively
siphoned or poured into the respective sample bottles.
Sediment samples for purgeable organic compound analyses will be collected in
4-ounce (120-ml) sample containers and will be filled completely with no head
space remaining in the containers.

3.3 SUBSURFACE SOIL
\ Five boreholes will be placed in the trench area. See Figure 1 for the exact
placement of these boreholes. Sampling will be conducted in the unsaturated
zone at 3-foot centers using a split-spoon sampler. The samples from each
borehole will be composited into one, making one sample per borehole. Soils
from each borehole will be removed from the sampling device with approximately
2 inches from the top, middle, and bottom of the sample being placed in a
glass pan, then thoroughly mixed with a Teflon spoon. The remainder of the
soil will be placed in plastic wrap and discarded.
Split-spoon samples will be collected from each shallow monitor well borehole
at 5-foot intervals. The split-spoon will be advanced through the hollow-stem
auger and forced to the desired depth by means of a 140 pound weight or
hammer. The split-spoon will be removed from the hole and opened to reveal
the sample. The undisturbed sample will then be visually described and
classified in accordance with the USC system by a qualified geologist or
hydrogeolog ist. Finally, the samples fro·m each borehole will be composited
and placed in appropriate sample containers.
For sample splitting for duplicates or quality control measures, a sufficient
volume for all sample containers will be collected in a large glass, Teflon
(or equivalent) compositing jug and then, with mixing, be alternatively placed
into the respective sample bottles.
Additio~ally, geochemical testing procedure to evaluate soil attenuative and
adsorptive capacity. The geochemical testing will involve three Shelby tube
samples collected from a known uncontaminated area near existing Well No. 6.
Well No. 6 was installed as a control well to monitor background water quality_
at the site. It is situated on a topographic rise in the extreme southeast
corner of the National Starch and Chemical Corporation property. Sampling of
this well has shown that it does not contain any base/neutral or acid
extractables, purgeables, or any other HSL organic pollutants. The three
Shelby tube samples will be collected by positioning a drilling rig near Well
No. 6 and pushing the Shelby tubes into the saturated s·aprolitic zone.

3.4 DECONTAMINATION PROCEDURES
The drilling rig and associated tools will be decontaminated before entering
the site and will be cleaned between borings. All drilling equipment will be
decontaminated between boreholes to prevent cross contamination. The drill
rig should be cleaned as described below:
• The engine and power head should be cleaned with a power washer or
steam jenny, or hand washed with a brush and detergent (does not have
to be laboratory detergent but should not be a degreaser) to remove
oil, grease, and hydraulic fluid from the exterior of the unit.
These units should be rinsed thoroughly with tap water.
All auger flights, auger bits, drilling rods, drill bits, hollow-stem
augers, split-spoon samplers, Shelby tubes, or other parts of the
drilling equipment that will contact the soil or ground water should
be cleaned as outlined below:
-Wash equipment thoroughly with laboratory detergent and hot warer
using a brush to remove any particulate matter or surface film
-Rinse equipment thoroughly with hot tap water
-Rinse equipment thoroughly with deionized water
-Rinse equipment with solvent and allow to air dry
-Rinse the stainless steel or metal sampling equipment thoroughly
with tap water in the field as soon as possible after use.
The drill rig will also be inspected for any leakage of hydraulic fluid, oil,
transmission fluid or other organic compound which could possibly contaminate
the soils. The rig will be filled with gasoline or diesel fuel before being
brought to the drilling site. Once the drill rig is brought to the site, it
will be assumed that the surface soils are contaminated and no equipment will
1When this sampling equipment is used to collect samples that contain oil,
grease, or other hard to remove materials, it may be necessary to rinse the
equipment several times with pesticide grade acetone or hexane to remove the
materials before proceeding with the first step. In extreme cases, when
equipment is painted, badly rusted, or coated with materials that are
difficult to remove, it may be necessary to steam clean, wire brush, or
sandblast equipment proceeding with the first step. Any stainless steel
sampling equipment that cannot be cleaned using these procedures should be
discarded.

be set down on the ground where it could be contaminated. Clean plastic
sheeting, aluminum foil, or cardboard will be placed on the ground to provide
a work surface for each hole.
The materials that will enter the borehole (augers, rods, etc.) will be
carefully cleaned as outlined above. The sample split spoons used for visual
soil classification will be decontaminated after each sampling drive using the
same procedure.
All surface sampling equipment will be decontaminated following the above
described procedure after each sample is collected.
Drilling personnel will wear appropriate protective clothing as required by
the Health and Safety Plan. Thes,e measures will not only protect the driller,
but will also protect the hole from cross contamination. All protective
equipment (gloves, boots, etc.) will be decontaminated before reuse or
disposal, using the procedure outlined earlier.
The drill rig, tools, and other drilling equipment will be cleaned before
leaving the site.
3.5 LOCATING UTILITY LINES
This section outlines the provisions IT will use for identifying and locating
utility lines, buried pipe, and miscellaneous equipment which may be
contaminated, and for determining the extent of contamination.
To locate the placement of utilities, sewers, and various other buried objects
on plant grounds, the plant foreman or superintendent will be contacted to
review the plant's as-built drawings. The foreman will also help IT personnel
stake, mark, or otherwise identify the underground objects near the proposed
soil boring locations. This will be done to minimize accidental uncovering or
damage to the utilities during drilling operations. In addition, the local
public works department and utility companies will be contacted to ascertain
the location of existing municipal utilities and electric, gas, and telephone
lines that may be buried in the area. This information would be applicable to
both on-site and off-site plant grounds. If it is necessary to expose

portions of these utilities during drilling, a representative of the
particular utility company will be requested to.be present. The
representative will witness the location and condition of the uncovered
utility, as well as provide positive identification. The locations of buried
utilities and other objects will be presented in the RI report.
3.6 DISPOSAL OF CONTAMINATED SOIL AND WATER
It is not anticipated that water will be used in the drilling process.
Therefore, disposal of contaminated recirculation water is not of concern
during this phase of the project. However, all water generated during well
installation, well developing and purging, and equipment cleaning will be
disposed of in the NSCC plant system and then discharged to the Salisbury
municipal sewer pending their approval.
During drilling and sampling operations, contaminated soil, disposable health
and safety gear, and water from decontamination efforts will be generated.
The total amount of contaminated material produced is expected to be
relatively small. The cuttings will be drummed and moved to a central area on
the site. Water from the decontamination processes will be discarded near the
point where the boreholes are drilled. Disposable safety equipment (i.e.,
booties, gloves, outer coverings) will be decontaminated and disposed of with
other solid wastes generated by the plant.

4.0 QA/QC SAMPLING PROCEDURES
Duplicate and blank samples will be collected during the sample program. In
general, o~e duplicate will be collected for every 20 samples collected and
one blank will be obtained for every 20 samples taken.
Duplicate sediment samples will be obtained by simultaneously filling two sets
of sample bottles, using standard sampling equipment and procedures. These
will then be treated as separate samples for labeling and shipping. Duplicate
samples will be logged in the field activity daily log.
Standard sampling equipment and procedures will be used for blank sampling.
Sediment blanks will be placed in a decontaminated stainless-steel scoop
before being placed in sample containers. Blank samples will be treated as
separate samples during identification, logging, and shipping procedures.
The Project Operations Plan (under separate cover) details specific sampling
protocol for sample collection.

5.0 SAMPLE PROCESSING
The sediment, surface water, and ground water samples will be processed
according to the procedures summarized in Table A-1. All holding times will
be as stated in Table A-1 unless otherwise specified in analysis method.
While awaiting shipping, all samples will be stored on ice in coolers. All
samples will be preserved on the same day that they are collected. If samples
cannot be shipped on a particular day, packaging will be delayed until the
following morning so that the samples can be shipped with a full load of
ice. These samples will be stored on ice in coolers and kept in a secure
area.
Coolers will be shipped by a next-day delivery service to the IT Environmental
Analytical Laboratory in Knoxville, Tennessee. Notification of shipment,
including airbill number, will be phoned to the laboratory either at the end
of business the day the samples are shipped or, if a later shipment· is made,
by 9:00 a.m. the following day.

(bl . . . . Sample preservation should be performed inmediately upon sample collection. For composite chemical samples,
each aliquot should be preserved at the time of collection. When.use of an automatic sampler makes it impos-
sible to preserve each aliquot, then chemical samples may be preserved by maintaining at 4"C until compositing
and sample splitting is completed.
(c) Samples should be analyzed as soon as possible after collection. The times listed are maximum times that
samples may be held before analysis and still be considered valid. Samples may be held for longer periods only
if permittee, or monitoring laboratory, has data on file to show that the specific types of samples under study
are stable for the longer time. Some samples may not be stable for the maximum time period given in the table.
A permittee, or monitoring laboratory, is obligated to hold_the sample for a shorter period if knowledge exists
to show this is necessary to maintain sample stability.
(d) Should only be used in the presence of residual chlorine.

When the extractable analytea of concern fall within a single chemical category, the specified preservative and
maximum h11lding times should be observed f11r optimum safeguard of sample integrity. When the analytes of
c11ncern fall within two or m11re chemical categ11ries, the sample may be preserved by cooling to 4•c, reducing
residual chlorine with 0.008% sodium thiosulfate, storing in the dark, and adjusting the pH to six to nine;
samples preserved in this manner may be held f11r seven days before extraction and 40 days after extraction.
Exceptions to the optional preservation and holding time procedure are noted in footnote (d) (re the re-
quirement for thiosulfate reduction 11f residual chlorine) and footnotes (k) and (1) (re the analysis of
benz id ine). ·
(k)If 1,2-diphenylhydrazine is likely to be present, adjust the pH of the sample to 4.0t0.2 to prevent rearrange-
ment to benzidine.

Extracts may be stored up to seven days before analysis if storage is conducted under an inert (oxidant-free)
atmosphere.
For the analysis of diphenylnitrosamine, add 0.008% Na 2s2o3 and adjust pH to seven to ten with NaOH within 24
hours of sampling.
The pH adjustment may b~ performed upon receipt at the lab11ratory and may be 11mitted if the samples ar~ ex-
tacted within 72 hours of collection. For the.analysis of aldrin add 0.008% Na 2s 2o3 •

7.0 FIELD DOCUMENTATION PROCEDURES
7.1 SITE LOCATION PROCEDURE
Following identification of boring and surface soil sampling sites, a wooden
stake (approximately 2 inches by 2 inches by 24 inches) will be driven into
the ground, allowing approximately 8 to 10 inches of the stake to remain
visible aboveground. The top portion of the stake will be painted orange and
labeled for identification. The label will contain the sample location number
and type. The location of each stake may be recorded by use of a transit and
stadia rod.
7.2 PHOTOGRAPHS
Photographs will be taken of each sampling site to show the surrounding area
and the objects used to locate the site. The picture number and roll number
(if more than one roll of film is used) will be logged on the field activity
daily log to identify which sampling site is ·depicted in the photograph. The
film roll will be identified by taking a photograph of an informational sign
on the first frame of the roll. This sign will have the job and film roll
numbers written on it so as to identify the pictures contained on the roll.
For example: National Starch
Roll Number 1
Frame Number 1 of 36
September 1, 1986 -(photographer's name)
7,3 FIELD ACTIVITY DAILY LOGS
All field data collection activities will be recorded on the field daily
activity log as shown in the QAPP. Entries will be described in as much
detail as possible so that the situation can be reconstructed without reliance
upon memory, Logs will be kept in project files in the IT Knoxville office's
Central Files.
Entries on the logs will contain a variety of information. At the beginning
of each entry, the date, start time, weather, all field personnel present,
level of personal protect1on being used on site, and the signature of the

person making the entry will be entered. The names of visitors to the site
and the purpose of their visit will be recorded. All entries will be made in
ink and no erasures will be made. If an incorrect entry is made, the
information will be crossed out with a single strike mark. All measurements
made and samples collected will be recorded. Wherever a sample is collected
or a measurement is made, a detailed description of the location of the
station will be recorded. All equipment used to make measurements will be
identified, along with the date of calibration. Samples will be collected
following the procedures documented in this plan. The equipment used to
collect samples will be noted, along with the time of sampling, sample
description, depth at which the sample is collected, and the volume and number
of containers into which the sample is placed in the field. Sample numbers
will be assigned before going on site.
A log of personnel and visitors on site will be maintained, including entry
and exit times. Major activities being performed or other items pertinent to
the history of the investigation will also be noted.

9.0 SAMPLING ACTIVITY SCHEDULE
The sampling program described in this sampling plan is expected to take 4 to
8 weeks to complete. The subsequent analyses will require a turnaround time
of approximately 3 to 4 weeks. Based on the results, either the feasibility
study may be undertaken or the scope of the RI will be expanded (Phase II) and
additional sampling will have to be conducted. If an additional sampling
phase is deemed necessary, details pertaining to the scope of work for that
phase will then be provided.
