Subject: Expanded Site Inspection -PRESCORE
Georgia-Pacific Corp. Hardwood Sawmill (NCO 000 813 592)
Plymouth, Washington County, NC
Dear Ms. Gurley:
Enclosed herewith are the Prescore scoresheets for the Expanded Site Inspection (ESI)
conducted at the former Georgia-Pacific Corp. Hardwood Sawmill site (GA-PA)(NCD 000 813 592),
located on Plywood Drive, Plymouth, Washington County, North Carolina. ESI sampling, which
included off-site sediment and surface water sample collection and on-site soil sample collection, was
conducted June 19-20, 1995.
The primary source area at the site is an area of surficial soil contamination in the vicinity of
the dip vat/ lumber stacking area. This source area measures approximately 150' x 200' in size.
Laboratory analytical data for soil samples collected from depths of approximately 3 to 12 inches
bis during the ESI confirm an observed release of dioxin/furan isomers, PCB's, pesticides, metals, and
extractable organic compounds in the source area. Contaminant concentrations exceeding 3-times
background levels and those that were reported as being estimated due to high spike recovery or
above maximum calibration limit where background was non-detect, were considered for observed
release.
Because the drainage area of the site is flat and the soils exhibit a moderate to high infiltration
rate, overland run-off should be minimal. However, a drainage ditch that enters the Roanoke River
is present near the source area. Roanoke River samples GP-001-SD/SW were collected at this
probable point of entry (PPE #2), samples GP-010-SD/SW were collected approximately . I I-miles
downstream of the PPE. Samples GP-009-SD/SW were collected upstream of the loading dock
piers at PPE #1, approximately .28-miles upstream ofPPE #2 .

The overall score calculated for the site is 50. 03. The score is driven by conditions in the
surface water pathway, specifically due to an observed release of pentachlorophenol and various
dioxin/furan isomers in sample GP-001-SD. Sediment sample GP-009-SD also contained the same
contaminants found in GP-00 I-SD, although in higher concentrations. Because this sample was
collected near the western edge of the property, the river in this area has most likely been impacted
by unknown Georgia-Pacific and/or railroad operations. Sediment and surface water samples WC-
003-SD/SW, collected during the Weyerhauser Co./Plymouth SIP, were used for comparison of
background river conditions . Weyerhauser Co. SIP samples were collected concurrently with the
GA-PA ESI. The Roanoke River is a closed fishery although people were observed fishing from the
. pier at the site during the ESI. Prior fish tissue sampling data that confirms that human food chain
organisms in the surface water pathway have been impacted by dioxins/furans. This data was not
used in scoring the Georgia-Pacific site as other sources along the Roanoke River could be
contributing to the fish tissue contarninationi. Prior groundwater sample data has shown that shallow
groundwater at the site has been impacted by site specific contaminants. The primary drinking water
source within the 4-mile site radius, the Castle Hayne Aquifer, has not been impacted by conditions
at the site.
