PECTIONONE Introductior
This confimator-y sampling (CS) Workplan was developed in accordance with requirements set
forth in Resource Conservation and Recovery Act (RCRA) Permit No- NCD047368642-RI
(permit) issued by the North Carolina Department of Environment and Natural Resources
(NCDENR) to the DuPont Fayetteville Works (site) on December 2, 1997. The permit stipulates
that DuPont prepare a CS Workplan to determine if the solid waste management units (SWMUs)
and area of concern (AOC) listed in Appendix A of the permit have released hazardous waste or
hazardous waste constituents to the environment (Table 1). This Workplan includes a:

Assurance Manual, and North Carolina Hazardous Waste Permitting Branch Confirmatory
Sampling Warkplan Guidance - Interim Drafi Final, July 1994.
1.1 BACKGROUND
E-L du Pont de Nemours and Company (DuPont) owns and operates the .Fayetteville Works Plant
in the Duart Township of Bladen County, North Carolina. The facility is located 15 miles
southeast of the city of Fayetteville on N.C. Route 87, along the B laden-C umber] and county line
(Figure 1). The DuPont property was purchased as several parcels from several families in 1970.
The first manufacturing area of the Fayetteville Works was constructed in the early 1970s, The
facility is currently a manufacturer of plastic sheeting, fluorochemicals, and intermediates for
plastics manufacturing. A former manufacturing area, which was sold in 1992, produced nylon
strapping and Elastomeric Tape,
The geographic location of the facility is 34"50'30" North latitude, 78'50'00" West longitude.
The site contains 2177 acres cif relatively flat farmland and woodland bounded on the east by the
Cape bear River, N,C, Highway 87 on the west, and farmland on the north and south.
In addition to the manufacturing operations, DuPont operates a wastewater treatment plant
(wwrp) for treatment of process waste. Hazardous waste generated as a result of the chemical
process and laboratory analyses are currently managed in drums at the Hazardous Waste
Container Storage Area prior to being shipped offsite for treatment, disposal, or recycling.
In September 1993, a RCRA Facility Assessment (RFA) was submitted to the NCDENR, The
RFA was resubmitted in December 1996 and identifies 24 SWMUs and four AOCs at the site. A
Ago& figure identifying the location of these units is provided in Appendix A. Based in part on the
RFA, the NCDENR identified three SWMUs and one AQC that require CS and are the subject of
this Workplan (Figure 2).

The DuPont Fayetteville Works consists of three main areas, where the following products are
manufactured:
Area 1 0 Butacite(& polyvinyl butyral sheeting - the plastic inner layer
of automotive safety glass.
Area 11 0 Nafiong Fluorocarbon membrane for electrolic cells.
* Fluorocarbon intermediates for Naflong membrane,
Teflon(P) resin, and Vitong elastomers.
* Polysiloxane Abrasion Resistance Coating (PARC),
Area.111 & Dymetrolg nylon strapping,
0 EPS Elastomeric tape for tape drives such as auto window
regulators.
1.1.2 Regulatory
The Fayetteville Works operates under permits from several regulatory programs; CR-A/solid
waste, NPI)ES/water quality and air.
7V RCRA/Sofid Waste Permits: The facility received its initial RC: RA Permit (NCD047368642)
to operate a hazardous waste container storage area and tanks in February of 1983. An amended
Part A application was last submitted in 1991 to document upgrades to its fluorocarbon waste
treatment and tank system.
11
The RCRA Part B permit application submitted in August 1993, identified a total of 71,750
gallons of container storage capacity at the container storage area. Waste stored included
characteristic wastes (DOO I, D002, D003, D007, D009, and D029) and listed wastes (F002,
F003, and F005). This permit was reissued and became effective on January 1, 1998, and will
remain effective for 10 years,
NPIDESAVater_Quality Permits: The Fayetteville Works also operates under a National
Pollutant Discharge Elimination System (NPDES) Permit No- NCO003573 with discharge to the
Cape Fear River. The earliest known water pollution control activity associated with the site was
the issuance of a temporary discharge permit by the North Carolina State Stream Sanitation
Committee.
Since the original permit, this facility has been continuously permitted, holding discharge
permits issued by the North Carolina Department of Water and Air Resources, and more
recently, by the EPA/state NPDF-S branches, The most current NPDES permit will expire May
31,2001.

"16ECTIONONE Introductior
Air Qualily, Permits, The Fayetteville Works currently has permitted air emissions sources.
These sources are associated with boilers, process equipment such as exhaust stacks, condensers,
mist eliminators, scrubbers, filters, and tank vents. The State regulatory agency established a
system of source registration in 1971 and changed to emissions permitting in 1974. Permit
requests were submitted to the State for the Fayetteville Works on an as -needed basis between
1971 and 1978. During the mid-1980's NCDENR began combining emissions permits into one
or two facility emission permits. Presently, the. Fayetteville Works has all sources combined
under one permit (No. 3735R,17), which is under continuous modifications as new sources are
added to the facility.
The objective of the CS is to determine if any of the units listed in Appendix A of the RCRA Part
B permit have released hazardous waste, or hazardous waste constituents (Table 1). A release
may be indicated by the discovery of any constituent previously or currently managed in a
SWMU or A discovered by virtue of its detection in media beyond the engineered boundary
of the unit and in concentrations of organic compounds above Practical Quanitation Limits
(PQLs) or concentrations of"metals above the 95 percent Upper Tolerance Limit (95 percent
UTL) for background soil concentrations. If a release is identified, then the unit will require a
RR to dekm-nine the extent and impact of the release -
A secondary objective of the CS is to provide data that will assist in the prioritization of those
units that require an RFI. The purpose of this prioritization is to identify those units that pose the
most potential for harm to human health and the environment. The prioritization will support
risk management decisions making an effort to best utilize DuPont and NCDENR resources.

Facility Characterization
2.1 REGIONAL SETTING
The DuPont Fayetteville Works is located on 2,177 acres, 15 miles southeast of the City of
Fayetteville at the Cumberland-13 laden County line. The site is bounded on the east by the Cape
Fear River and on the west by NC 87- This area is characterized by generally low topographic
relict' except along the west side of the Cape Fear River,
The majority of the site is located on a relatively flat plateau with an elevation of approximately
145 feet above mean sea level (MSL). Relief is more moderate on the northern portion of the
property along Willis Creek, west of the Cape Fear River, and near the Georgia Branch located in
the southern region of the site. Slopes near the drainage areas range from approximately five to
20 percent while the slope on the plateau is generally less than 0.5 percent.
The DuPont Fayetteville Works is located on the boundary between Cumberland and Bladen
Counties with 75 percent of the land within Bladen County- This area is entirely within the
Coastal Plan Physiographic Province, The Coastal Plain consists of a seaward thickening wedge
of sedimentary deposits ranging in age frorn Cretaceous to Recent. These deposits are underlain
by Paleozoic age metamorphic and Igneous rocks. In the northern Bladen County these
"basement" rocks are approximately 400 feet below the surface.
10 The `Tuscaloosa Formation (also known as the Middendorf Fm.) of late Cretaceous age
unconformably overlies the basement rocks. This formation consists of red, gray and yellow
interbedded sands and clays. The sand layers are lenticular, poorly sorted and arkosic. The clay
luycr� are massive, and dominate the formation in outcrop.
Unconformably overlying the Tuscaloosa Formation, the Black Creek Fon-nation can be found at
the surface in Bladen and Southern Cumberland Counties- In outcrop, the Black Creek is
composed of dark gray, fine grained sandy clay and very fine to coarse sand. It is dark gray to
black in the subsurface or in fresh exposures and brick red where it has been deeply weathered.
The formatioi-I is approximately 300 feet thick in northern Bladen-
Thc Duplin Marl of'Miocene age outcrops in a few areas along the Cape Fear River where it fills
irregular depressions in the Black Creek Formation. The marl is composed of gray shells in a
matrix of gray gilt and fine to medium sand.
Surface deposits that cover much of the area are thought to be Pleistocene in age. They consist
of white to tan very fine to coarse sand associated with a mottled tan sandy clay. Locally, the
thickest deposits are found east of the Cape Fear River, while on the west side of the river they
are often absent.
The soil on the Fayetteville Works Plant site falls within the Norfolk -Goldsboro -Rains general
classification (Soil Survey of Bladen County, 1990). These soils are on old, high stream terraces
III the northern part ol'Bladen County- They range in being well to poorly drained soils that have
a sandy or loamy surface layer and a loamy subsoil.

?ECTIONTWO FaMIJIVCharaCterilation
The Black Creek Formation and surficial deposits are the principle aquifers in the site area. The
layers of sand within the Black Creek Formation supply much of the groundwater locally,
especially for the larger supply wells. The surficial deposits in the site area provide water for
many small domestic wells.
It is assumed that the general groundwater flow in the site area would be to the east toward the
Cape Fear River. However, a natural high point directly east of the former WWT'P lagoons
directs the groundwater flow in that area to the southwest and northwest, and if the groundwater
flow follows the area's surface topography, it would eventually turn back to the east toward the
river.

The Cape Fear River is located along the eastern boundary of the Fayetteville Works
approximately 1850 feet away fTom the manufacturing and associated buildings. Willis Creek, a
tributary of the Cape Fear Rivef is located in the northern portion of the site approximately 3,000
feet away from the manufacturing area. An effluent channel leading to the Cape Fear River is
located ,just south of the plant and is used as the outfall area covered by NPDES Permit number
NCO03573. Only parts of the Georgia Branch are within the southern boundary of the site.
Surface water runoff firom the manufacturing areas which are not captured by the process sewer
system, are captured by the storm sewer system and is directed to the wood -lined ditch which
also discharges into the effluent channel.
The plant facilities are located on a plateau area approximately 70 feet above the 100 and 500
year flood plains and at least 1,000 feet from the 100 year flood plains nearest approach.

unit characteristics
0 This section describes the three SWMUs and one AOC that will be the focus of the CS
17J
investigation. The locations of each SWMU and AOC included in the CS are shown in Figure 2.
These areas are discussed in terms of the dates of operation, unit and waste characterization, and
potential migration pathways. Unit characterization describes the location, operational history,
operational status, construction, and processes of each SWMU/AOC. Waste characterization
describes the wastes managed by the units. Migration pathways define the environmental
medium most likely to be impacted by a release from the unit- In most if not all cases, soil is the
initial medium impacted by a release from a unit; hence, soils below the CS units will be the
focus of the investigation. The RFA also provides a description of these units.
The SWIG Us/AOC identified in the Hazardous Waste Management Permit as requiring a CS are-
• SWMU 6 - Process Sewer System
❑ SWMU 7 - Storm Sewer System
❑ SWMU 9 (A, B Sr. Q - Former WWTP Lagoons
❑ AOC-C - Former Ag Products Gasoline/Diesel UST Area

Unit Characterization
SWMLJ 6 is a system of underground sewer pipes, manholes, and sumps which convey process
wastewater from the main plant areas to the site's WWTP system (Figure 3)_ Plant personnel
and site sewer map,,, indicate that the pipes are constructed of reinforced concrete, vitrified clay
and steel. There are four process sewer sumps throughout the plant and all are in -ground and
constructed of reinforced concrete these include the following: Butaciteg sump; PVA sump'
Nation (P common sump-, Semiworks sump, All sumps are concrete -lined, and the Na one
common sump is also polylined-
Waste Characterization
The unit manages wastewater from the ButaciteT) Area, DymetrolS Area, Naflong Area and
Power House Area. The wastewater may contain any of the wastes generated or raw materials
managed at the facility. Based on interviews with DuPont personnel, Appendix D contains a list
of process materials that may be found in small quantities in the process sewer system. The
following is a brief description of the waste streams from each process area that may enter the
process sewer system'.

9 Nafion 0 Area: The process sewer leaving the Naflone area contains process wastewater,
cooling water, and steam condensate from the various manufacturing units. The Nafiong
internal process sewers notTnaliy contain only cooling waster or steam condensate. During
floor washing, small quantities of process materials and lute oils may be washed into the
sumps. Closed sumps within the Naflont area are tested for pH and the presence of a heavy
fluorocarbon liquid phase. If pH. is not neutral or if a fluorocarbon phase is detected, the
sump material is drummed for disposal by incineration.
Butaciteg Area: The process sewer from the Butacitek area contains process wastewater,
cooling water, steam condensate, rain water and filtered water.
a Power House Area. The waste stream that enters the process sewer system from the Power
House Area consists of sulfuric acid and caustic from the neutralization sump and tank.
Releases from SWMLJ 6 would impact soil and potentially groundwater.
TA [Tj RZANUS i'l a Vjjji
Dates of Operation: 1972 to present
SWMU 7 consists of asysten-i of sumps, drains and ditches located throughout the plant which
collect stormwater that is eventually routed to the Cape Fear River. The storm sewer system is
constructed of earthen drainage ditches and a wood lined ditch, The stormwater collection
system is designed to handle a combined rate of approximately 13,900 gallons per minute (gpm)
Engineering control devices are in place to prevent the mixture and/or contact with plant process
constituents, Rainfall accumulated in permed chemical containment areas and other engineered
spill containment structures are routed through the process sewer system after the waters have
been tested and approved for such discharge.
Confirmatory sampling is being focused on a small section of the storm sewer system where
solid polyvinyl alcohol (PVA) particles were observed in the storm sewer system actiacent to the
PVA unloading area of the Butacite(-R) area, Methanol is normally present in PVA and is a likely
contaminant resulting from the PVA being present in the storm sewer. This section of the storm
sewer is shown on Figure 5.
The unit manages storm water from throughout the plant- Small amounts of PVA from the rail
40 car unloading area have reportedly been conveyed to the storm sewer through surface water
runoff.

FORMER WWTP LAGOONS
Dates of Operation: Lagoons A & B 1979 to 1990
Lagoon C 1972 to 1979
Unit Characterization
SWMU 9 A and B. consists cif unlined lagoons used for the settling of sediments from process
and sanitary wastewater. From 1979 until the current WWTP was completed, these lagoons
served as biosludge settlement lagoons for the plant's wastewater before discharging to the Cape
Fear River. These lagoons replaced SWMU 9 C lagoons prior to the startup of the Nafione area.
The lagoons were inground, trapezoidal in. shape and consisted of approximately eight
impoundment cells. SWMU 9 A and B dimensions were approximately 180 feet by 270 feet by
6 feet and were located east of the existing WWTP. The lagoons were made up of several
impoundment cells that were operated by alternately filling the cell with treated effluent, letting
Am& the sludge settle, then decanting the supernate to the WWTP.
The two lagoons (SWMU 9 A and B) were dismantled in 1990. A plate and frame filter press
was used to process the sludge present in the lagoon, Filtrate generated by sludge processing
was returned to the WWTP. Sludge residuals that remained on the lagoons bottoms and sides
after primary sludge processing, were removed. Cement kiln dust was used to bind any free
liquid to insure scrapings passed the paint filter test. The lagoons were backfilled with the same
soil that was removed to construct them. The sludge and scrapings were properly disposed of at
the 13171 Sampson County Landfill.
SWMU 9.C. were the first lagoons constructed at the facility in 1972- SWMU 9 C was
constructed by building earthen berms using the soil excavated when the original Equalization
Basin and original clarifier were built for the WWTP. The lagoons were constructed to handle
blOSIUdge. generated at the WWTP from the Butaciteg process. The lagoons were operated by
filling separate impoundment cells one at a time, letting the sludge settle, then decanting the
supernate to the WWTP.
Prior to the startup of the Naflon 9 process, SWMU 9 C lagoons had become full of sludge and
Were closed. SWMU 9 A and B lagoons were constructed to replace SWMU 9 C. The locations
of the former WWTP lagoons are shown on Figure 6,
Waste Characterization
SWMU 9 A and B received both process and sanitary waste from throughout the facility.
However SWMU 9 C received process and sanitary waste from the Butacite(& area only.

10 migration Pathways
The lagoons were in -ground and unlined. Potential releases from these SWMUs would primarily
be to the subsurface soil and gToundwater. A system of groundwater monitoring wells has been
installed as per NCDENR requirements. The wells in the area of this unit were designed 10
monitor impacts to the groundwater from past activities.
The monitoring wells are constructed of either 2 inch or 4 inch diameter PVC pipe. Each well has
a 5 foot screen with standard gravel packing -
Date of Operation. 1977 to 1989
This area consisted of three 1,000 gallon underground storage tanks that contained gasoline and
diesel fuel (42 fuel oil) used in association with the Agricultural Products test farm area. The
tanks were removed in 1989. The holes were backfilled after tank removal and are now an
unused, grass covered area. Figure 7 shows the location of AOC-C,
.4 Waste Characterization
These tanks handled gasoline and diesel fuel.
The tanks were made of metal and were removed intact with no visual holes or defects noted at
the time of removal. After the tanks were removed the tank excavations were also inspected for
any sign of leakage and none was found. Releases from the tanks would impact soil and
potentially groundwater.

Project Management Plan
'Phis Project Management Plan (PMP) has been prepared by W-C Diamond Group as part of the
Workplan preparation effort for implementation of a RCRA CS at the DuPont Fayetteville
Works. The purpose of a PMP is to communicate and document the management approach for
the project. The PMP contains the following sections,
❑ Technical approach
D Project Schedule
❑ Persorwel (including roles and responsibilities)
This PMP is intended as a supplement to the CS Workplan. Each project team member
identified below will be familiar with the, CS Workplan. Additional documents (e.g., Waste
Management Plan, Health and Safety Plan (HASP), field notes logbook, sample status logbook,
etc.) may be developed as part of the pre -field mobilization effort as needed to ensure that all
field activities are completed safely and effectively.
The technical approach employed for this project will include:
❑ Selecting qualified personnel to perform management and technical duties
1* • Field investigation
0 Data review and interpretation
0 Project management
0 Report preparation activities
U Effectively managing the personnel and project to meet the objectives of the CS
Workplan
❑ Assembling and reviewing available data pertaining to site and technical studies
0 Executing effective investigative studies, as described in the CS Workplan
❑ Analyzing data and interpreting findings
❑ Presenting the data, findings, and conclusions resulting from the investigations
❑ Communicating with NCDENR (as required)
The CS Workplan outlines an investigation that will be performed to determine if a release of
hazardous constituents have occurred from the SWMUs and AOC listed in the permit as
requiring CS (Table 1). If a release of hazardous constituents is determined to have occurred
frorn a particular unit, a recommendation will be made to NCDENR to progress to the next phase

Project Management Plan
The CS Workplan also describes the development and use of a Conceptual Evaluation Model
(CEM) which will be used to prioritize all of the units that will require an RFL The CEM will be
used to compare the relative potential for a unit, Or group of units, to pose a threat to human
health and the environment. Based on the results of this evaluation, a risk management decision
can be made regarding which units should be addressed first.
A schedule has been developed for implementation of the CS Workplan and is presented in
Appendix B. The duration of specift tasks reflect the current understanding that DuPont has
regarding the scope of each task and is based on the experience of implementing similar
programs at other DuPont facilities. Since implementation of the CS depends upon NCDF-NR
approval of the CS Workplan, no fixed dates have been indicated on the schedule.
DuPont understands that the CS is the first phase in a multi -phased RFI (if required). Since each
phase builds on the preceding phase, a detailed schedule for the entire program cannot be
completed at this time. If the CS phase of the investigation indicates a release of hazardous
constituents from a particular unit, an, updated schedule will be prepared for the next phase of the
investigation, the RFI Workplan.

This sampling and analysis plan (SAP) presents a prograrn that will provide information to
determine if potential release has occurred from selected units at the DuPont Fayetteville Works.
The RR Guidance Document (EPA Publication 530/SW-89-03 1) was used to develop
monitoring and data collection elements of this Workplan. All analyses will be perfon-ned in
accordance with procedures described in Test Methods for Evaluating Solid Waste,
PhysicallChemical Methods, EPA Publication SW-846 [Third Edition (September 1986), as
amended by Update I (July 1992)]. As described in the PMP in Section 4.0, the CS is the, first
phase in a multi -phased RFL Only CS activities are described herein.
Groundwater and soil (surface and subsurface) will be sampled during the CS. Unit -specific soil
investigations will be performed to provide preliminary information on elevated constituent
levels within or near the units. Urtit-9pecific groundwater investigations may be performed to
determine groundwater elevation and flow direction, and to provide preliminary information on
elevated constituent levels in the groundwater near the unit. Sampling locations and depths have
been carefully selected to provide samples representative of site conditions, and biased.to sample
the most likely point of release. Based on facility records and the RFA for DuPont Fayetteville
Works (DERS, 1993 revised 1996), analytical parameters for each sample have been determined
by considering knowledge of the waste and constituents handled in the units and the operational
history of the units. In SWMUs where a variety of wastes could possibly have been managed, a
46 more extensive list of analytical parameters, such as volatile organics, will be implemented. For
units with a well-defined operational history, a more specific sampling and analysis plan is
applicable.
The field procedures outlined in the guidance documents in Appendix C will be followed during
all phases of the field investigations or variance will be noted- The data management plan in
Section 6-0 details the use and presentation of collected data.
ReleawsOf Organic constituents from the units will be determined by comparing the reported
constituents to background which is assumed to be non -detect. An organic constituent release
will be. confirmed for a unit if reported concentrations exceed the PQL. Also, releases of metals
from a unit will be determined by comparing the analytical results to background concentrations
for the metals listed on Table 2-
` o determine site background concentrations of metals, 4 soil borings will be advanced to
approximately 12 feet below ground level (8GL). Figure 2 shows the proposed locations for the
background soil borings. Soil samples will be collected at intervals which are geologically
equivalent to sampling horizons around the MMUs. (i.e., background metal samples consisting
of unsaturated surficial aquifer material will be collected for comparison to samples collected in
that same horizon near a SWMU). A total of at least 12 soil samples (three per boring) Will be
collected. 'Soil samples will be analyzed for the metals listed in Table 2.

SECTIONFIVE Confirmatory Sampling And Analysis Plan
10 Background concentrations will be calculated using the UTL approach described in Statistical
Analysis of Groundwater Monitoring Data at RCRA Facilities {EPA, 1989a). The UTL is the
upper limit of the tolerance interval which establishes a concentration that contains a specified
portion (P) of the population with a specified level of confidence (Y). For calculation of
background concentrations, a P of 95 percent and a Y of 95 percent will be used. Thus, there is a
95 percent confidence that the calculated UTL will contain 95 percent of the distribution of
background concentrations for each constituent. .Procedures for calculating tolerance limits are
detailed in Section 6.4.1. Soil samples will be classified by soil horizon and compared to
background U'ri,s from the same horizon.
Borings will be advanced using a GeoprobeTM or hollow -stem augers, and soil samples will be
collected in split -barrel samplers or Shelby tubes. Some areas of the site may be inaccessible to
drilling rigs, in those areas, a stainless steel hand auger will be used to collect samples. For
logging purposes, all borings will be continuously sampled, but only the sampling intervals
specified in each SWMU will be collected for laboratory analysis. Appropriate guidance
documents are provided in Appendix C. Table ') describes soil boring depths and number of
borings at each SWMU, and Table 4 summarizes the analytical parameters. All soil sample
analyses will be reported on a dry weight basis to meet the requirements of the NCDENR
Division of Waste Management- If groundwater elevation is above the base of the unit for
01 SWMU 6 and AC C - C, groundwater samples wwill be collect in lieu of soil samples for that unit.
During the sampling activities, all work will be monitored with an organic vapor detector, such
as a flame ionization detector (FID), as a means of assessing the presence of volatiles in soil at
the various sampling locations. Other monitoring may be conducted to fulfill requirements of the
pro ' iect HASP, All samples will be collected, preserved, transported, and analyzed in accordance
with the guidance documents in Appendix C.
All solid wastes generated will be placed into 55-gallon drums and scaled for final disposition at
a later date. To avoid cross -contamination between sample locations, all field equipment will be
decontarninated before use at each boring location, in accordance with guidance documents
included in Appendix C.
The groundwater investigation portion of the CS will focus on potential releases from SWMU 9
A, 13, and C and SWN4U 6 or ACC - C where the base of the unit is below the water table.
Groundwater information collected from sarnple points, monitoring wells and temporary wells
will be used to depict groundwater flow direction. Samples collected downgradient will be
compared to upgradient samples for that area of investigation. If no significant increase in
groundwater concentration levels exists between the upgradient and downgradient wells, and no
elevated concentrations are detected in the downgradient groundwater and surrounding soil
110 samples (relative to site background information), then data from both media will confirm that no
release has occurred.

(Figure 6). The monitoring wells near SWMU 9 A, B, and C will be sampled within the same
time period.
If groundwater elevations are determined to be above the invert of SWMU 6 or ACC - C
groundwater samples will be collected from GeoprobeTA pre -packed screens installed within the
soil boring. To minimize turbidity and the effects of drilling, groundwater samples will be
collected from the temporary wells a minimum of 48 hours following completion and
development. Water levels will be measured in newly installed wells and existing wells ill the
vicinity of the investigated SWMUs with an electronic water level indicator. Water level
measurements in new and existing wells will be perfom-ied prior to sampling groundwater.
Methods for purging and sampling monitor wells are detailed in the guidance documents in
Appendix C and include methods described in the RCR,4 Groundwater Monitoring Guidance

5.5 SAMPLING LOCATIONt
Boring locations for each unit were selected using process and historical knowledge to determine
where releases were likely to have occurred- If no information is available to predetermine soil
-sample locations, then the borings will be located adjacent to the unit, and the soil samples will
be, taken immediately below the base. Borings located within a unit shall not damage an
engineered unit. Boring locations of units without well-defined boundaries (i.e., WWTP
Lagoons) will be located within the known area. Samples will be taken below the base of the
unit in native soils,

A total of 9 soil borings will be completed adjacent to the process sewer system. Sample
locations were selected based on observations made during a January 1998 site inspection. Nine
soil borings will be completed along the sides of pipes and pipe joints along the entire process
sewer system (Figures 3 and 4). Soil boring locations were selected near sumps, lift stations and
manholes where several process sewer lines converge. These locations were selected because
they represent worst case locations for leakage around joints and connections. Soil samples will
be collected from the base of the sewer line to two feet into natural soil (Table 3). The borings
will be terminated at the first occurrence of saturated soils. No soil samples will be collected

calibration are included in Table 5. When the manufacturer has not specified a calibration
interval for an instrument, W-C Diamond Group will establish one. Field equipment will be
46 supplied and maintained by W-C Diamond Group or Ha7-co Services.
The pH meter calibration will be checked at each well through the use of two buffer solutions
that bracket the historical range of pH in the wells to be sampled. The meter will be calibrated
daily in accordance with the manufacturer's specifications and SW-846 standards. The probe of
the rneter and sampling cups will be thoroughly rinsed with deionized",ater before and after use.
Calibration procedures are described in the guidance documents for this instrument.

percent), it will be recalibrated according to the procedure defined in the guidance documents for
this instrument. The probe of the meter and sampling cups will be thoroughly rinsed with
deionized water before and after each use.
The static water level (SWL) in a well will be measured through use of an electric water level
indicator, The SWL will be measured 1rom a scribed mark at the top of the well casing.
The FID or OVA detector will be used for health and safety monitoring and for screening Soil

The frequency of calibrating field instruments is summarized in Table 5. For the p1q meter,
buffers will be at pH 4, pH 7, and pH 10. Two of the three buffers will be used to calibrate the
meter. The pH 7 buffer is always one of the calibration buffers, and the second buffer (pH 4 or
pH 10) will be consistent with the parameters of the samples collected in the field. if the samples
are acidic, then the pH meter will be calibrated with the pH 4 buffer. If the samples are alkaline,
then the pH meter will be calibrated with the pH 10 buffer. If the sample parameters for pH
cannot be determined prior to calibration, then one buffer, either pH 4 or pH 10, will be used to
calibrate the pH meter. If pH 4 is selected and the pH of the collected sample is above 7, then the
pH meter will be recalibrated with the pH 10 buffer and the sample will be reanalyzed with the
final result recorded in the field notebook- Likewise for the pH 10 buffer, if it is selected and the
pH of the collected sample is below 7, then the pH meter will be recalibrated with the pH 4
buffer, and the sample will be reanalyzed- The buffers will be purchased from a laboratory
chemical supply, and the exact pH will be noted in the field notebook.
For the conductivity meter, reference solutions will be in the range of 1,000 µomhs/cm. The
median standard will be used for calibration checks. Reference solutions will be purchased from
a chemical supply manufacturer.
For the FID or OVA,, span gases will be purchased from chemical suppliers. These gases will be

will be the first set of containers filled.
Field blanks, equipment blanks, and trip blanks will be used to identify potential sources of
contamination. The field blank is analyte-free water transferred from one vessel to a sample
container at the sampling location, and then preserved with the appropriate reagents.
Equipment blanks (field riniate blanks) are used to evaluate equipment cleaning Or
decontamination procedures. At the sample location, analyte-free water or deionized water is
poured over or through the sample collection device, collected in a sample container, and
preserved as appropriate.
A trip blank consists of sample containers filled at the laboratory with analyte-free or deionized
water. The trip blank travels to the site with the empty sample bottles and back from the site
with the collected samples in an effort to simulate sample handling conditions. Trip blanks are
not opened in the field -
All blank,-., are handled, V411Sported, and analyzed in the same manner as the actual field samples.
If possible, blanks should not be held on site for more than four calendar days. The temperature
of all the blanks, except the trip blanks, must be maintained at 4°C while on site and during
.shipment. The trip blank is not shipped to the site on ice, but must be maintained at 4'C when

Data Manauement Plan
This data management plan (DMP) presents a program for systematically managing information
acquired during the CS investigation. The DMP describes procedures for recording data,
displaying data, evaluating data, and determining the need for fWlher action,
A data record for in.formation collected during a CS must be developed to provide all information
needed to subsequently analyze and assess the results of the field and laboratory work. Data
records require consistent labeling and recording of field observations to fkilitate future data
reduction and analysis and to eliminate the need for speculation concerning the quality of
observations or the influence of environmental factors on an ultimate result. For each sample or
measurement collected as part of the data record, the following information shall be provided:
I , Unique sample number
I Sampling or field measurement location and sample or measurement type
3, Sampling date
4. Sampling or field measurement raw data
5- Property Or component measured
G. Results of analysis (concentration)

Information will berecordedin field notebooks to document the procedures used and the
prevailing conditions during the field investigation. Previous field records will be reviewed at
each site visit, and any unusual site conditions encountered during the field investigation will be
described to allow interpretation of erroneous data at a later date. Field documentation of
activities will be comprehensively recorded, so data may be easily interpreted at a later date,

Each sample collected as part of this CS will be assigned a unique number. The sample number
will indicate the type of sample media and the sampling location. The sample media will be
indicated by the format of the sample name. A SWMU number and depth will be included in the
sample name for soil samples. A monitor well (N4W) number (and no sample depth) will be
included for groundwater samples.
For example, the first soil sample collected at SWMU 6, Sampling Station Number 1, could be

include tabulation of measurements and observations and graphical displays to summarize
information as it relates to conditions present at the site. It is anticipated that raw data will be
evaluated predominantly through use of the appropriate tables and screening procedures to
evaluate outliers and to produce data summaries. Final data will be assessed using a variety of
summary procedures, including tabular and graphic forms.

Raw data will be presented and evaluated in tabular form using electronic spread sheets. In
addition, data will be sorted and evaluated by examination of their relationship to the site to
determine the presence of outliers or invalid data points. The following will be presented in
tabular displays:
0 Unsorted (raw) data
L1 Results for each medium or for each constituent monitored

El Summary data
These, displays will be prepared electronically to prevent transcription errors and facilitate rapid

completed, final tables and displays will be prepared-
AM1�'inal project data will be displayed, where applicable, using a variety of graphical methods to
AalloI and development ofa clear understanding of the sampling locations, areas
where more data are needed, and levels of constituents at each sampling location.
Spatial distribution of constituents found will be examined through displaying constituent
concentrations on site facility maps representing the various sampling points. Where
appropriate, maps will be prepared to indicate groundwater flow, changes in concentration in
relation to distances from the source, and constituent concentration patterns. Features affecting
intermedia transport will be displayed, as well as identification of potential receptors.
Subsurface information will be displayed using vertical profiles and cross -sections to allow an
examination of the change in impacts to soil or groundwater with depth. This type of display
also will allow an examination of substrata- Hydrogeologic cross -sections will be used as
appropriate to evaluate more fully the relationship of groundwater to potential releases from the
site. At the present time, it is not anticipated that three-dimensional plots and stratigraphy fence
diagrams will be necessary for description of features present at the site.
Data collected during the CS investigation will be evaluated using statistical methods.
Background concentrations will be established for naturally occurring substances such as metals
for comparison with substance concentrations detected during the CS. The steps that will be

• Distribution testing
• Handling, of nondetect values
• Calculation of tolerance limits
• Comparison of discrete sample values to limits
Data Management Plan
The calculations of tolerance limits and comparisons of discrete sample values are detailed in
Section 6-4.
Data Collection Planning
The first -step in planning a statistical evaluation of a data set is to determine the requisite size of
the data set.
The distribution of the data will be tested to determine if the data set is normally or lognormally
distributed (or nonnomial). Normal and lognormal distribution will be tested by observing a
probability plot of the untransformed and the natural log transforrn of the data. Lognormality
A06
Re will also be tested by calculating the Shapiro -Wilkes test statistic (EPA, 1989a and 1992b). The
statistical method used in deriving the UTL (for background data) or the upper confidence limit
(UCL) (fbr site data) will be dependent upon the distribution of the data.
Nondetects in normally distributed data (ifnondelects are less than IS percent of the data set)
will be handled by substituting the detection limit for the nondetect value, If the data are
normally distributed and nondetects are greater than 15 percent of the data set, then Cohen's
method will be used- lithe data are lognormafly distributed, nondetects will be handled using
the Probability Plot method (also known as Helsel's Robust method),
A criterion for determining whether a release has occurred from SWMUs/AOC included in the
CS will be a comparison of sample data with area background concentrations. For organic
AWIL. compounds, "background" concentrations will be the PQL. For naturally occurring substances,
background concentrations will be those concentrations that occur in areas of the facility that
have, not been affected by industrial activities.

IECTIONSIX Data Management Plar
The CS activities typically are not intended to generate sufficient numbers of samples from each
environmental medium associated with a SWMU to allow generation of statistically -derived
upper bound concentrations- As a result, maximum concentrations of naturally occurring
chemical constituents detected at each SWMU investigated will be used as the basis for the
comparison with background concentrations. This approach introduces a high level of
conservatism.
Data will be collected to characterize area background concentrations of naturally occurring
substances in soil. 'The concentrations of naturally occurring chemical constituents in the
background data will be used in the risk assessment to determine the presence of chemical
constituents that might have been introduced to the environmental medium under evaluation as a
result of industrial activities (Le., site -related), Background concentrations of naturally occurring
substance,, in soils will be represented by collecting a set of 12 soil samples. Background
concentrations of naturally occurring chemical constituents in groundwater will be obtained from
published background values for the area -
The UTL will be derived from background samples collected for soil samples only. The
statistical method used in deriving UTLs will be dependent on the distribution (i.e., normal,
lognormal, or nonnormal) of the data.
is Calculation of Tolerance Limits
After the underlying distribution of the data set is determined and nondetect values are evaluated,
the UTI, of the data set will be calculated according to the appropriate distribution. For normally
distributed data:
Where:
UTL = x + ks
X � Sample mean
k = Tolerance factor (95 percent coverage, 95 percent confidence)
S = Standard deviation
For lognormally distributed data:
UTI, = e {x + ks)
Where:
X = Sample mean
k = 'Tolerance factor (95 percent coverage, 95 percent confidence)
10 S = Standard deviation
e = 2,718

DEQ-CFW-00032201
SECTIONSIX
Data management Plan
For nonparametric data sets, the UTL is assumed to be the maximum value of the data set,
according to EPA guidance (EPA, 1992b),
Discrete sample concentrations of the field sampling data will be compared to the background
UTL concentrations. If the sample concentration is less than or equal to the background UTL
concentration, then the sample may be assumed to be a me-mber of the background population. If
a particular constituent in a field sample has a concentration greater than the background 1.31-L,
then the constituent may be assumed to be a member of a population different from the
background population.
However, due to the nature of the UTL calculation, it is possible that as much as five percent of
the true background population exceeds the UTL (EPA, 1992b). Thus, if less than five percent
of the samples exceed the background UTL for a given constituent in a given area, the
constituent may not be considered to be present above what could be expected from samples
collected from a naturally occurring distribution of that constituent.
All units designated for investigation in the RF1, by exhibiting a release as determined by this CS
effort, will be subject to prioritization. The objective of the prioritization effort is to identify
those units on the DuPont Fayetteville Works that have the greatest potential to adversely affect
human health or the environment. Once the unit prioritization process has been completed, the
RF1 can be focused on first investigating the higher priority units. Lower priority units may be
addressed in order of importance (i.e., medium and low priority) at a later stage in the Corrective
Action process.
Prioritization ofthe SWMUs/AOCs will be performed by applying available site -specific
information contained in the CEM and, when appropriate, professional judgment to determine
which units (if any) are the most significant contributors to health and environmental risk.
Prioritization will be based on the unit's potential to:
0 Cause fire/eNplosion or pose some other serious safety hazard
11 Release significantly beyond the perceived boundary of the unit
:1 Adversely affect the health of'human (and, in some situations, ecological)
receptors that might come in direct contact with affected media within the unit
LJ Migrate to other environmental media such as air. groundwater, surface water, and
sediments
13 Migrate to off -site receptors-, both human and ecological

An excellent source of information to be used in creating the CEM unit prioritization process is
NCDENR's Guidance. for the Use of RCRA National Corrective Action Priorilization System
(NCAPS) in North Carolina, which was published on August 29,1995 (NCDENR, 1995). The
guidance was based largely on the USEPA's NCAPS system to tank Hazardous Waste Treatment
Storage and Disposal Facilities (TSDFs) in the United States. NCDENR augmented the EPA
guidance with information, such as climatological information, that is specific to the state to
allow for ranking of facilities located in North Carolina.
The NCDENR NCAPS prioritization system will serve as ab.asis for the development of the
CEM and prioritization of RFI units. The NCAPS scoring system is divided into four sections,
namely groundwater, surface water, air, and on -site- Although the final criteria to be used in
prioritizing the units have not been selected at this time, minimum criteria have been decided and
consist of the following:
D Confirmation and significance of release from each unit. Sample data collected
from the CS or other activities at the facility forms the basis for such
determination. However, in the absence of sample data, information included in
documents such as the R-FA is critical to determining the confirmation or potential
significance of a release,
40 El ldentification of the potential for migration to groundwater, such as the depth to
groundwater, the net annual precipitation in an area, and the physical state
(e.g., solid, liquid, gas) of the materials disposed in or present at each unit.
Q Integrity of any containment systems that might be present at some or all units.
Whether the unit exists as a surface impoundment, as a container/tank, as a pile of
solid material, or as a landfill is significant to the evaluation of integrity.
0 Toxicity and persistence of'chemical constituents that are confirmed to be present
or, in the absence ol'analytical data, that might be. present within a unit,
D If'available, the quantities of waste materials that might have been disposed of
within a unit.
0 Potential receptors and area groundwater use patterns in the vicinity of a unit.
D Distances from a unit to the nearest potential receptors.
�@-
0 Presence of an observed release from a unit, either by surface runoff or by
discharge of groundwater into a nearby surface water body.
D Physical and chemical characteristics of a chemical substance that are conducive
to migration potential to surface water.
0 Integrity of unit in respect to containment.

Data Management Plan
Prioritization of each of the SWMUs;`AOC subject to investigation during the RFJ will be
documented in the CS Report. The actual ranking of each criterion listed above will be
quantitative, as presented in the NCAPS guidance. There also will be a need for subjective
ranking, such as when there is a professional judgment input that is appropriate. Professional
judgment criteria that will be considered include such factors as the existence of additional
regulatory controls that apply at the units (i.e., -NPDES or solid waste), community concerns, and
any additional site -specific information relevant to the prioritization process. Any additional
criteria that might become relevant when the units are prioritized will be incorporated
subjectively into the priontization. Weighting of some criteria over others, also a subjective
criterion, likely will be considered when the prioritization is performed. When subjective inputs
are part of the prioritization process, the reasoning behind such inputs will be included in the text
of the CS Report.
A limited amount of additional information regarding the site's environmental characteristics
beyond that which presently exists or will be provided by this CS effort may be desirable to
provide the appropriate level of infom-lation to support the prioritization process and resulting
recommendations, If additional analytical data is deemed necessary and/or appropriate, DuPont
will communicate and coordinate with NCDENR any sampling efforts that will be conducted to
provide this information.

Approved by
1.1 Purpose
The purpose of this guideline is to provide instruction for purging a groundwater well prior to
collecting samples for chemical analysis. Potential huards are addressed in the Health and
Safety Plan (HASP).
This procedure must be carried out in the following rnamer:
I - Be aware of safety- Don appropriate personal protective equipment (PPE), as
prescribed by the project HASP for the project.
2. Locate the desired monitoring well using a current site map. Note the following
information in the field notebook or sampling data sheets: date, time, job site location,
well identification nw-nber, ambient weather conditions, name of sampling personnel,
purge method and equipment, and any other field observations such as well box
condition, standing water, etc-
11151 FVIMIMSJIMM�= T1 R
4. Check for the presence of volatile hydrocarbons in the well headspace with a calibrate-i
photo ionization detector (PID)/flame ionization detector (FID). Record thrt.
measurement, Take any additional safety precautions as indicated in the HASP for the
headspace gas reading recorded.
5, If the well is known not to contain light non -aqueous phase liquid (LNAPL), take the
depth -to -water measurement in the well using an electronic water level meter.
Other -wise, use an interface probe to measure the LNAPL thickness and depth to water.
Record all measurements in the field log,
6. Using the electronic water level meter or the interface probe, lower the probe end of the
meter or interface probe until it touches the bottom of the well.
7, Holding the measuring tape near the measuring reference point, alternately raise and
lower the probe to get an accurate feel of the bottom of the well. Record this
measurement in the field log.
S. Calculate the total volume of standing water within the well casing.

9, Calculate the volume of water to be purged, usually three well volumes,
10. If a bailer is to be used, attach a sufficient length of new rope to the bailer.
H. If a centrifugal, peristaltic, or, bladder pump is to be used, attach sufficient hose to the
pump and lower it into the well.
12, Begin purging the well, The well should be purged at a rate low enough to prevent
water from cascading down the sides of the well, if at all possible.
13. When no sediments are visible in the purging water, connect the water quality meters.
14, Measure the temperature, electrical conductivity, and pH of the water withdrawn from
the well. Record these values in the field log. Repeat the measurements at regular
intervals.
15. Continue purging the well until the measured parameters stabilize, to within 10 percent
for two consecutive measurement. If the measured parameters do not stabilize, five
well volumes should be removed, At this point, the well is ready for sampling.
16- If the well is purged to dryness or is purged such that recovery exceeds two full hours,
the well should be sampled as soon as a sufficient volume of groundwater has entered
the well to enable the collection of the necessary groundwater samples.

18, Store any contaminated liquid, PPE, or disposable equipment in labeled storage drums
for future disposal.

1.0 INTRODUCTION
MJEL=
The purpose of this guideline is to provide guidance for the collection of groundwater samples
for chemical analysis.
This procedure must be carried out in the following manner.
I - Be aware of safety, Don appropriate personal protective equipment (PPE),
prescribed by the project Health and Safety Plan for the site. i
2. Be certain that measured groundwater parameters have stabilized.
3. The choice of sampling containers, preservation, and holding times should be based
on consideration of the desired analytes.
4- When using a bailer, care must be taken to minimize agitation or aeration of the
14 water; ibis could lead to the loss of volatiles and to a nonrepresentative sample. The
decontaminated bailer should be lowered slowly into the well, filled, and then lifted
out while preventing the bailer or the rope from contacting my potentially
contaminated surface, such as the ground.
5- The more volatile samples sbould be collected first. For example, volatile organic
analysis (VOA) bottles and total organic halide (TOX) should be filled first,
followed by serni-volatile organics, inorganics, and metals.
6. Care must be taken to prevent the sample container rim or cap from contacting any
potentially contarninated surface such as fingers, rope, bailer, or pump tubing.
7- When pouring from the bailer, direct a slow, steady stream of water into the sample
container, trying to minimize the aeration of the sample.
8. For sample containers with septums, fill the sample container to the top of the
container so that a meniscus is formed. Allow any air bubbles to rise to the surface.
Carefully and quickly screw the cap onto the container and finger tighten.

This procedure must be carried out in the following manner:
I . The OVA will not "detect" any inorganics (metals).
2. The OVA will "detect" methane, which is explosive, but relatively nontoxic. The user
should determine if the contaminant involved is or is not methane.
3. Department of Transportation (DOT) shipping regulations are strict for the OVA when
shipped containing pressurized hydrogen.
10 4. A relative humidity greater than 95 percent will cause inaccurate and unstable
responses.
5. A temperature of less than 40°F will cause slow and poor responses.
6. Actual contaminant concentrations are measured relative to the calibration gas used.
Therefore, specific contaminants and their quantities cannot be easily identified.
7- The actual operating instructions issued by the manufacturer should always be used, as
these are regularly updated, and may affect instrument warranty.
2.1 Procedures ]For Startup
1. Read and familiarize yourself with the instruments operating instructions. Be aware of
safety. Don appropriate personal protective equipment (PPE), as prescribed by the
project Health and Safety Plan.
2. Connect the probe/readout connectors to the side -pack assembly.
3, Check battery condition and hydrogen supply. Be certain that an extra, charged battery
is on supply,

7. Open the H2 tank valve all the way and the H2 supply valve all the way. Check that the
hydrogen supply gauge reads between 8.0 and 12.0 prig.
8. Turn the PUMP switch ON, and check the flow system according to the following
sections.
9. Check that the BACKF LUSH and INJECT valves are in the <UP> position.
10, To light the flame, depress the igniter switch until a meter deflection is observed. The
igniter switch may be depressed for up to five seconds. Do not depress for longer than
five seconds, as this may burn out the igniter coil. If the instrument does not light,
allow the instrument to run several minutes and repeat the ignition attempt.
11. Confirm the OVA operational state by using an organic source such as a "magic
marker."
12. Establish a background level in a clean area or by using the charcoal scrubber
attachment to the probe (depress the sample inject valve) and by recording
measurements referenced to the background-
13, Set the alarm level, if desired,
14, Determine the areas in which sampling is to take place. Document these areas in the
Real Time Instrumentation Data Log. Be certain to note the date and time the sample
was taken for each sample.
15. Survey the area for organic vapors. The tip of the probe should be placed as near as
possible to the monitored source. If any response occurs, note the findings on the Data
Sheet, If there is no response on the OVA, record "N/R" on the Data Sheet,

1.0 INTRODUCTION
1.1 Purpose
The purpose of this document is to provide guidance for the use and calibration of the Thenno
580B Photo ionization Detector (PID)- No hazards are generated by the use of this instrument,
but other hazards may exist where it is used. These hazards will be addressed in the job -specific
Health and Safety Plan.
PENEWMEW Of
This procedure must be carried out in the following manner;
1. Be aware of safety. Don appropriate personal protective equipment (PPE), as
prescribed by the project Health and Safety Plan. The use of this instrument itself
requires no special PPE.
2, The instrument is recharged by connecting the charger. This should be performed the
night before field use.
3. Unscrew the metal sample tube from the rest of the unit to check that the porous
aluminurn air filter is not dirty or missing. Also note that the outside surface of the
filter must be inside the sample tube. Without the filter, readings will be extremely
erratic. Put the sample tube back on the instrument,
4. Depress the "On/Off" key. This powers the lamp and starts the sample pump. Aix -
should now be pulled into the instrument through the sample tube.
5. Calibration of the instrument should be performed as per the attached instructions. First
the instrument baseline should be set to zero using the "zero air."
6, Then the "span gas" (the isobutylene) is used to calibrate over a range. Span gas should
be of a practical range (100 and 250 ppin are good).
7. When the flow regulator is being removed from the cylinder, it will pop off at the end
of the threads. This is not a hazard, but be sure to hold the regulator firmly as it is
unthreaded.
8. After calibration is complete, return the instrument to "Run" mode. Calibration should
be done every day. The instrument does not have to be running, however, to hold
calibration.

9. As a check for the instrument, pass a source of volatiles (such as correction fluid or a
marker) near the sample tube. The instrument should register a value. An alternate
check is to half` fill the Tedlar& bag with the span gas, and check the concentration in
run mode. If the instrument registers within approximately +/-10pereent, then
calibration is still valid.

1, Volatile chemicals that have an Ionization Potential (IP in eV) greater than the IP of the
PID lamp are undetectable by that lamp.
2- High humidity interferes with the readings of the instrument.
3. Chemicals with a different response factor than isobutylene may give readings higher or
lower than the actual concentration,
4, The instrument assumes a linear response of signal to concentration. When a
concentration greatly exceeds the concentration of the span gas, the value becomes
increasingly inaccurate.

AND PIEZOMETERS Approved by
MiEff=.-
The purpose of this guideline is to provide guidance for the installation of monitoring wells,
recovery wells, injection wells, observation wells, and piezometers. Hazards will be addressed in
the project Health and Safety Plan.
I. Be aware of safety- Don appropriate personal protective equipment (PPE), as
prescribed by the project Health and Safety Plan for the project.
2. Prior to installing a well or a piezometer, a bore hole mast first be advanced to the
required depth (see Guideline 5002 for hollow -stem auger drilling procedures, or
Guideline 5001 of rotary drilling procedures). Well/piezometer installation takes place
at Step 8 of Guideline 5002, or at Step 8 of Guideline 5001.
3. The diameter of the well to be installed will depend on the, intended use for the well and
possible engineering considerations and needs. A minimum two-inch annular space is
required between the borehole and the casing (for example the inner diameter of the
auger used to install a four -inch well shale be 8-1/4 inches). When drilling with
hollow -stem augers, the inside diameter of the augers is what must be measured to
determine borehole size.
4, All well screen and well casing used should be new and of adequate structural integrity,
and should be made of material that will be compatible with the contwnination present
(or anticipated), Screen size should be determined using sieve analysis. Screen length
should be adequate to monitor the zone of interest, and in general should not be less
than five feet long nor greater than 20 feet.

Teflonll� tape can be used to wrap the threads to ensure a tight fit and minimize leakage.
Teflon'& "0" rings can also be used ("0" rings made of other materials are not
�icceptable if the well is to be sampled for organic compounds).
6. Thread additional lengths of well screen together, as needed, until the appropriate total
well screen length is achieved. Do not use cement or glue.
T Thread solid well casing (in 10-foot lengths) onto the well screen section to complete
the well to a height approximately two feet above the ground surface. Do not use
cement or glue.
Centralizers should be placed on wells greater than 50 feet.
T. Once the well screen and casing have been placed in the bore hole, place filter pack
material in the annulus between the bore hole wall and the well screen. The type of
filter pack material used will depend on the intended use of the well and the geologic
f0mation that the bore hole penetrates (sieve analysis).
9. Pour a minimum of six inches of the filter pack material under the bottom of the well
screen to provide a firm footing and unrestricted flow under the screened area. Filter
pack should extend a minimum of two feet above the top of the well screen, and should
be placed by a tremie pipe where possible. If drilling with hollow -stem augers, the
augers should be lifted as the sand is tremied into the borehole.
If it is impracticable to tremie the filter pack, pouring the sand is acceptable in shallow
bore holes (less than 50 feet), where the annular space is large enough to prevent
bridging. The level of the filter pack materials must be measured at appropriate
intervals to ensure no bridging has occurred.
10. Once the filter pack material has been placed, place a seat above the filter pack in the
annulus of the bore hole to provide a watertight seal. The seal should be a minimum of
two feet thick and should consist of a minimum of 20 percent solids bentonite. This
type of bentonite is available in either powder or pellet form.
The preferred method of placing either bentonite pellets or a bentonite powder/water
mixture is by tremie pipe. If this method is not practicable (pellets only), pouring the
pellets is acceptable in shallow bore holes (less than 50 feet), where the annular space is
large enough to prevent bridging. The pellets must be tamped, and measured at
appropriate intervals to ensure they have not bridged.

The bentonite seal must be allowed to hydrate for eight hours or the manufacturer's
recommended hydration time, whichever is greater. Measure the seal after hydration
time to ensure that the required two feet of seal is present.
1. After the bentonite seal has hydrated, grout the remainder of the borehole to prevent
surface water infiltration.
12. The grout, material used will conform to applicable local, state, or federal regulations.
Unless otherwise specified, the grout will be a mixture of Portland cement and
bentonite powder. The grout will have a minimum density of 9.4 lbs/gal (going in and
coming out of the hole) to ensure proper set-up. The grout density should be measured
with a mud balance.
13. Once the grout has been mixed, tremle it into the annulus between the well casing and
the bore hole wall. Remove the drill rig auger flights/steel casing that remain in the
bore hole as the grout mixture is added. Be sure to leave the auger flights/steel casing
at least one foot below the top of the grout, to prevent caving of the bore hole. Unless
otherwise specified, the grout will be allowed to handle a minimum of 24 hours before
well development.
14. For well protection and security, install a steel protective casing with locking cap
approximately three feet above the surface (two feet below). If the well is installed in a
roadway, install the steel protective casing to a height slightly above the road surface to
prevent inflow of surface waters. Well protection and security may differ if engineering
remediation design dictates the necessity for something different
The outer protective casing should be installed into the borehole a minimum of 24
hours after the grout has been poured.
15. Prior to the use of a well or piezometer, well development must be perforTned to rest
the natural hydraulic properties of the formation that were disturbed during drill
operations (see Guideline 4102 for well development procedures).
16. Decontaminate all equipment prior to moving to the next location. See Guideline 720]
for procedures concerning equipment decontamination.

2. Well development occurs a minimurn of 24 hours after the installation of monitoring
wells, recovery wells, injection wells, observation wells, and piezometers (see
Guideline 410 1). Either a truck -mounted hydraulic surge block, a submersible pump,
or bailer are used to develop a well.
3. Prior to initial surging of the well, purge the well of approximately three to five well
bore volumes to clear out any fine sediments that accumulated in the well during
installation. A submersible pump or bailer can be used to purge the well.
4. Slowly lower the surge block into the well, using a truck -mounted hydraulic winch,
until it is near the top of the screened section.
5- Using the hydraulic winch, alternately raise and lower the surge block through a
vertical distance of one to two feet- The velocity of the surge block motion will depend
on the tightness of the formation in which the well is installed.
6, After surging the well a few times at a given depth, move the surge block deeper into
the well by one or two feet and repeat Step S.
7, Repeat Steps 5 and 6 until the surge block has been lowered to the bottom of the
screened section of the well.
8, Slowly raise the surge block out of the well.

1.0 INTRODUCTJON
1.1 Purpose.
The purpose of this guideline is to provide guidance for the general use and operation of a rotary
drill Tig for installing a borehole. Pou-ntial hazards will be addressed in the project Health and
Safety Plan.
This procedure must be carried out in the following manner
I Be aware of safety. Don appropriate personal protective equipment (PPE), as
prescribed by the Health and Safety Plan for the project.
2. Prior to drilling, inform Utilities Locating Service so that any underground utilities in
the vicinity of the drilling site can be marked and identified.
3. If possible, use a hand auger to advance a hole where the drilling is to take place, and
use a hand-held locator to check for the presence of any underground pipes or cables.
4. When using water rotary, the potable water that is to be used must be analyzed for the
40 contaminants of concern prior to drilling_
When using air rotary, the air compressor most have an in -line organic filter system to
filter the air coming from the compressor.
When using mud rotary, only pre -analyzed potable water and bentonite drilling muds
may be used. All drilling materials must have adequate manufacturer documentation
for material use and constituents.
5. The water, air, or mud forced down the drill pipe, escapes through small ports at the
bottom of the di -ill bit, thereby lifting the cuttings and cooling the bit. The cuttings are
blown out of the top of the hole where they collect at the surface around the borehole.
As these cuttings collect, periodically remove them and place them on polyethylene
sheeting to avoid any possible leaching of contaminants that may be present.
6. Initially, advance the borehole at a slow rate as an extra precaution, so that any possiblo
contact with underground utilities will be less damaging,
7. If sampling or geotechnical evaluation is to take place during drilling, advancement
the borehole can be temporarily halted and the drill pipe removed from the borehol
thereby allowing the undistui-bed soil immediately beneath the borehole to be sampl
or evaluated (see Guidelines 1403 or 1406 for operating procedures for vario
sampling and testing techxiiques). The drill cuttings can also be sampled at any til
dalhL during the drilling operation (see Guideline 1407).

1.0 INTRODUCTION
Purpose
The purpose of this document is to provide guidance for the general use and operation of a
hollow -stem auger drill rig for installing a bore hole. Potential hazards will be addressed in the
project Health and Safety Plan.
This procedure must be carried out in the following rnanner:
I Be aware of safety, Don appropriate personal protective equipment (PPE), as
prescribed in the project Health and Safety Plan for this project.
2, Prior to drilling, inform Utilities Locating Service so that any underground utilities in
the vicinity of the drilling site can be marked and identified. If working on a plant site,
be sure to obtain an excavation permit.
AML
3, Use a hand auger to advance a hole where the drilling is to take place, or probe with a
small diameter steel rod, and use a hand-held locator to check for the presence of any
underground pipes or cables.
4. During the first five to seven feet of drilling, the hollow stem auger is advanced at a
slow rate as an extra precaution so that any possible contact with underground utilities
will be less damaging,
L]
5. Hollow -stem auger flights are five feet in length, therefore drilling is temporarily halted
at five-foot intervals so that additional auger flights can be attached. Auger flights are
attached to one another by threaded ends and bolts. Only TeflonO "0" rings are
acceptable to make augers watertight.
6, As excavated soil accumulates at the top of the bore hole, it is shoveled into a
wheelbarrow and moved out of the, way. Since the excavated soil may be
contaminated, it is placed on polyethylene sheeting to prevent any possible leaching of
contaminants,

IV 7. If sampling or geotechnical evaluation is to take place during drilling, advancement of
the hollow -stem auger can be temporarily stopped and the soil plug, if present, can be
removed. A device such as a split -barrel sampler or Shelby tube can be attached to the
center rod and lowered to the bottom of the bore hole. Sampling or testing occurs in the
undisturbed region of soil immediately beneath the deepest auger flight.
8. When the bore hole has been advanced to the depth desired, the center rods and soil
plug, if present, can be removed, thereby allowing well casing to be installed (see
Guidance Documents 4101 and 4201 for various types of well installation).
9. If the borehole is not to be closed through procedures outlined in other guidelines, then
it shall be closed by grouting with a cement/bentonite mixture (the local County
Department of Health guidelines will be followed).
10. Excavated material, PPE, and the polyethylene sheeting should be temporarily stored in
30- or 5-gallon drums on site for future disposal.
11. Upon removal of the auger flights and other down -hole drilling equipment, all of the
equipment should be decontaminated according to the procedures outlined in Guidance
Document 7201.

This procedure must be carried out in the following manner:
1. Be aware of safety.
2, Obtain a chain -of -custody and fill out all appropriate areas, including: analytical
laboratory address, type of analysis, number and type of samples, turnaround time, etc.
Sign the chain -of- custody as the "Relinquisher."
3, For glass sample containers, first place the sample container in shipping foam or a
bubble -pack wrapper to protect it from possible breakage during shipment.
4- If using, place the metal sample liners or cylinders into a Ziplocv plastic bag to prevent
any possible moisture ftom reaching the soil samples. Glass sample containers should
be wrapped in bubble wrap or placed in foam molds to prevent breakage.
5. Place the metal sample liners or sample containers into a large plastic bag and place the
bag into an ice chest.
6. Fill the bag with ice. Seal the bag by twisting and taping with strapping tape to prevent
leakage. Place packing material into the ice chest to fill any voids, if needed, to prevent
movement of the sample containers during shipment,
7. If the analytical laboratory sends a representative to pick up the ice chest, have the
representative sign the chain -of -custody as the "Receiver." If the ice chest is to be
shipped to the analytical laboratory, the lab representative receiving the ice chest will
open the ice chest, check the containers, sign the chain -of -custody as the "Receiver,"
make a photocopy of the chain -of -custody, and will send the photocopy back to the
"Relinquisher."
