Reasor Chemical Company
Field Sampling and Analysis Plan
WA No: 147•RDRD-A424
Revision: 0
Date: 12 February 2003
Weston Solutions, Inc. (WESTON®) has prepared this Field Sampling and Analysis Plan (FSP)
for the U.S. Environmental Protection Agency (U.S. EPA) Regions 4 and 5 describing
procedures for field activities required to complete the Remedial Design (RD) for the Reasor
Chemical Company (RCC) site located in Castle Hayne, North Carolina. WESTON has prepared
this report under Work Assignment No. 147-RDRD-A424 of Contract No. 68-W7-0026 with
U.S. EPA and in accordance with the 23 September 2002 U.S. EPA Statement of Work (SOW)
and the RD Work Plan prepared by WESTON dated 18 December 2002.
The Reasor Chemical Company Site is located in the southeastern part of North Carolina
approximately IO miles north of Wilmington, North Carolina. The specific site location is 5100
North College Road, 0.5 miles southeast of the intersection of NC Route 132 and US Route 117
in Castle Hayne, New Hanover County, North Carolina. The site is approximately 25 acres in
size.
The RCC site is the location of a former stump rendering facility, which operated from 1959 to
1972. RCC produced turpentine, pine, resin, pitch, tall oil, pine oil, camphor, pine tar, and
charcoal from pine tree stumps. The facility is believed to have used various solvents to extract
raw product from chipped stumps, distilling the extract into separate product fractions. The
solvents used in the extraction process were likely stored on site in 55-gallon drums, the remains
of which are still visible in a surface drum disposal area near the center of the property.

RCC operated the facility until I 972 when the property was sold to Martin Marietta Corporation
(MMC). Residual buildings, machinery, and equipment were to be cleared from the site before
1 December 1971, prior to the sale of the property to MMC. RCC intended to remove the boiler
room building and rosin warehouse 90 days from the date of closing. A fire, and possible
explosion, occurring on the property on 7 April 1972, damaged or destroyed the remaining
buildings and materials on the site property. At the time of MMC's purchase of the site, the
property consisted of ruins of some of the buildings, scrap metal, debris, and cardboard barrels
containing hardened resin. MMC, a producer of aggregates for the construction industry, never
conducted operations at the RCC property, and in I 986, MMC sold the property to Hilda C.
Cameron and Nathan S. Sanders and wife, Judia S. Sanders.
The property is currently vacant. Unpaved roads run along the inner periphery of the property and
throughout the site. The site is currently overgrown with brush and second growth forest. Site
features which are still distinguishable include three tank cradle areas (north tank cradle, south
tank cradle, and work tank areas), a boiler house, and the concrete slabs from the former rosin
warehouse, laboratory, garage, truck scale, still, process line, transformer area, train scale, pipe
shop, and several other unidentified former buildings across the site. Five surface impoundments
or ponds, which were likely used in the manufacturing process, a scrap copper area, two railroad
sidings, a surface drum disposal area, a sluice area, and several drainage ditches are also still
present at the site.
In August 1996, U.S. EPA issued a work assignment to WESTON to perform a Remedial
Investigation. The RI was completed in December 1999. The Remedial Investigation led to a
Focused Feasibility Study (FFS) to determine the most cost-effective remedial action for the
RCC site. The FFS was completed in July 2002.

U.S. EPA issued the Record of Decision (ROD) for the site in September 2002. The ROD called
for removal of approximately 500,000 gallons of contaminated surface water, excavation and
removal of 1,600 cubic yards of soil and sediment, and annual groundwater monitoring.
This Field Sampling and Analysis Plan (FSP) for the Reasor Chemical Company site presents the
procedures to be used in support of the Remedial Design (RD) for the site. Additional
information concerning project operations is contained in the Quality Assurance Project Plan
(QAPP) and the Health and Safety Plan (HASP) submitted under separate cover. The objective
of the RD at the Reasor site is to perform the necessary activities required to develop the final
plans and specifications, general provisions, and special requirements necessary to translate the
selected remedies as defined in the ROD into the remedy to be constructed under the Remedial
Action (RA) phase.
1-2 PROJECT OBJECTIVES
Meeting the goal described previously will require fulfilling the objectives and data requirements
itemized below:
• Surface Water: Surface water impounded by four of the five on-site ponds_will_be
pumped out and removed as part of the remedial action. A composite water sample from
all four ponds will be collected and analyzed for waste profiling using the TCLP
procedure.
• Surface Soil: Surface soil in three areas will be removed and disposed off-site. One
composite soil sample from these three areas will be collected and analyzed for waste
profiling using the TCLP procedure.
• Sediment: Sediment in the four on-site ponds will be excavated and removed after the
surface water has been pumped out. A composite sample will be collected from all four
ponds and analyzed using the TCLP procedure.

Revision: 0
Date: 12 February 2003
This section provides general operating guidelines for access, security, and the field team
organization that will be implemented during investigation activities, as referenced in the RD
Work Plan.
2.1 SITE CONTROL
2.1.1 Site Access
Access to the site is adequate to most of the study area; some roads may need to be cleared of
minor debris (man-made or natural). Locations for the additional monitor wells may need
minimal adjustment for trees, fences, and other obstructions.
2.1.2 Site Security
Since the site is only accessible by one road, a security gate with padlocked chain is in place to
limit access. The security gate and chain will be locked at the completion of each workday.
Monitor wells will be secured with a locking protective cover prior to the completion of a
workday.
2.2 PROJECT ORGANIZATION AND PERSONNEL RESPONSIBILITIES
The project team for WESTON at the RCC site will work under the direction of the EPA Work
Assignment Manager (W AM), the WESTON Program Manager (PM) and the Site Manager

Revision: 0
Date: 12 February 2003
The composite surface water sample will be submitted to a fixed laboratory for the required
analyses.
3.2.2.2 Sediment Sampling
If the surface water body is wadeable, the sediment samples will be collected by using a stainless
steel scoop or spoon. The sampling method will be accomplished by wading into the surface
water body and scooping the sample along the bottom of the surface water body. Excess water
may be removed from the scoop or spoon. However, this may result in the loss of some fine
particle size material associated with the bottom of the pond.
In ponds that are too deep to wade, but less than eight feet deep, a stainless steel scoop or spoon
attached to a piece of conduit can be used from the banks of the pond. If the above-mentioned
sampling methods are not practical, the Eckman dredge will be used to collect the sediment
samples. A sample from each pond will be placed into a stainless steel bowl, stirred, and mixed
thoroughly. The composite sample will be placed in the following containers for analysis:
• 1 -8 ounce glass
• 1 -2 ounce glass
• 1 -8 ounce glass
TCLP Extractable Organics
TCLP Volatile Organics
TCLP Metals
All sediment samples will be submitted to a fixed laboratory for the required analyses.
3.2.3 Surface Soil Sampling
Composite surface soil samples will be collected from three areas using a stainless scoop from
the O to 6-inch depth below ground surface horizon. The scoop will be advanced through the
selected sampling depth, and the contents will be emptied directly into a stainless steel bowl.

3.2.5 Monitor Well Installation
The newly proposed monitor wells will be installed using the hollow-stem auger drilling method.
The drill rig and all drilling materials will be decontaminated prior to beginning field work and
between installation of each well. Refer to Subsection 3.6 for decontamination procedures.
Figures 3-2 and 3-3 depict typical well construction details for shallow and deep wells,
respectively.
The materials and methods used m the construction of the monitor wells will include the
following:
• Well depth will be approximately 10 feet below the top of the water table for shallow
wells and approximately _25 feet below the water table for deep wells, which at the Reasor
site is expected to occur at approximately 5 feet below ground surface (bgs). The well
screen will be 2-inch, stainless steel, IO feet long for shallow wells and 5 feet long for
deep wells, and will have 0.0 I 0-inch slot widths.
• The bottom of the well screen will be fitted with a stainless steel end cap, which will be
threaded onto the screen. This cap will be placed within 0.5 feet of the open portion of
the well screen.
• The screen filter pack will be a silica sand, extending from approximately 0.5 feet below
the well screen to 2 feet above the screen.
• A 2-foot-thick bentonite pellet seal will be placed above the top of the filter pack and
allowed to hydrate for approximately 8 hours.
• The annular space will consist of a grout seal of 20: I cement and bentonite slurry.
Cement will be commercial Portland cement. The grout will be placed using standard
tremie techniques.

Monitor Well Development
The newly completed monitor wells will be developed,,~ ¥(hen the grout has been allowed to -----~------cure no less than 24 hours fnstallation. This will allow sufficient time for the well materials to --cure before the development procedures are initiated. A submersible pump will be used to
remove the residual materials remaining in the wells and to try to re-establish the natural
hydraulic flow conditions of the formation, which may have been disturbed by well construction
around the immediate vicinity of each well. The new monitor wells will be developed until the
column of water in the well is free of visible sediment,' and the pH, temperature, turbidity, and
specific conductivity have stabilized. Well development water will be handled and disposed of
as described in Section 3.4.
3.2.7 Monitor Well and Production Well Sampling
Monitor wells and on-site production wells will be sampled to establish the aquifer conditions
and to evaluate the groundwater quality. Two such groundwater sampling events are scheduled.

event when the status of the dedicated pneumatic pumps are verified.) Well purging and
sampling procedures will be performed in accordance with the EISOPQAM (Region 4 EPA-
SESD, November 2001, Section 7). Groundwater samples will be analyzed for total metals using
CLP methods.
3.2.7.1 Calculating Purge Volumes and Well Purging Procedures
Purge volumes during the well sampling phase will be computed in conjunction with the known
diameter of the well casing and the standing casing water volume. To calculate the purge
volumes:
I.

Multiply the standing casing water volume by a factor of three to establish the
minimum purge volume.
Record the measurements and the purge volume calculation in the field logbook
or on a monitor well sampling sheet.
Following the determination of the well purge volume, the well will be purged prior to collecting
groundwater samples. All of the existing monitor wells have dedicated, submersible, pneumatic
pumps that were installed during the remedial investigation activities. WESTON plans to utilize
these dedicated pumps for purging and sampling. The existing production wells will not have
dedicated pumps and the following procedures will be used for purging. In addition, these
procedures may also be used in the existing monitor wells if any of the dedicated pumps fail to
operate:

numbered pages. Entries in the logbook must include, at a minimum, the following:
• Date and time oflogbook entry
• Weather conditions
• Field observations
• Log and summary of daily activities and significant events
• Description of sample and sampling location
• Date and time of samIJle collection
• Number and size of sample taken
• Collector's sample identification number(s) and/or name
• References such as maps or photographs of the sampling site

• Reference to other field logbooks or forms that contain specific information pertinent to
field activities
• Discussion of problems encountered and their resolution
• Discussion of deviations from the Work Plan, EPA SOP, or other governing documents
Because sampling situations vary widely, notes should be as descriptive and as inclusive as
possible. Someone reading the entries should be able to reconstruct the sampling situation from
the recorded information. If anyone other than the person to whom the logbook was assigned
makes an entry, he/she must date and sign the entry.
3.7.2 Chain-of-Custody Procedures
I Written procedures must be available and followed whenever samples are collected, transferred,
stored, analyzed, or destroyed. The primary objective of these procedures is to create an accurate

written record that can be used to trace the possession and handling of the sample from the
moment of its collection through analysis.
A sample is in someone's "custody" if it is:
• in one's actual possession
• in one's view, after being in one's physical possession
• in ones' physical possession and then locked up so that no one can tamper with it
• kept in a secured area, restricted to authorized personnel only
3.7.3 Custody Transfer and Shipment
When transferring samples, the transferee must sign and record the date and time of transfer on
the Chain-of-Custody record. Custody transfers made to a sample custodian in the field should
account for each sample, although samples may be transferred as a group. Each person who I NOR/K:IWP\20064\147\FSP-Rev0-Feb03.doc 3-22 RFW-147-28-AMPB

number of custody records, the number of custodians in the Chain-of-Possession should be kept
to as few as feasible.

Retain a copy of the forms.
Mail packages by registered mail with return receipt requested or by common
carrier. When packages are shipped by common carrier, retain the receipts as part
of the permanent Chain-of-Custody documentation.
The laboratory will return a copy of the completed Chain-of-Custody with the
analytical results.
Samples to be shipped must be packed so as not to break the package seal or locked so that any
tampering can be readily detected.

WA No: 147-RDRD-A424
Revision: 0
Date: 12 February 2003
Data Quality Objectives (DQOs) are qualitative and quantitative references as to the quality of
data obtained from field-related sampling activities that allow or support administrative decisions
and/or regulatory action. Data generated will be used in the decision-making process leading to
the remedial action. The investigative methods and associated DQOs are detailed in the project
Quality Assurance Project Plan (QAPP).
4.2 INTENDED USE OF THE DATA
The intended use of the data generated as a result of the RD is to monitor groundwater quality for
metals concentrations and to profile surface water, sediment, soil and surface soil to finalize
disposal options. This data will be made available to potential bidders for remedial action
activities.
