S. Environmental Protection Agency Region IV Atlanta, Georgia Prepared by: CDM 2030 Powers Ferry Road, Suite 325 Atlanta, Georgia 30339 I I I I I I I I I I I I I I I I I I I alM Executive Summary The Georgia-Pacific Hardwood Sawmill Site (hereinafter referred to as the "Georgia- Pacific Site" or "the site"), is defined as the 24-acre area located on Plywood Drive within the city limits of Plymouth, North Carolina. Contaminants consisting primarily of dioxins/ furans, polynuclear aromatic hydrocarbons, pentachlorophenol, pesticides, polychlorinated biphenyls, and a few heavy metals were released into the environment during past sawmill wood treating operations. Soil, surface water, sediment, and groundwater samples, both onsite and offsite, were collected by Science and Ecosystem Support Division personnel. Sample analyses were performed by the EPA's Contract Laboratory Program. Dioxins and furans were analyzed by an EPA Special Purchase Agreement laboratory. Analytical results were validated by the Science and Ecosystem Support Division Quality Assurance personnel. The following is a summary of the analytical results: • • • Analyses of soil samples collected indicate extensive contamination by dioxins/ furans, polynuclear aromatic hydrocarbons, polychlorinated biphenyls, and inorganics. This contamination seemed to be focused in an area centrally located on the site property where most past operations were located. There was indication of offsite contamination from site related constituents, however the concentrations were lower than onsite concentrations. Surface waters at the site discharge into the Roanoke River. Analyses of surface water and sediment samples collected from the int~rmittent drainage ditches located onsite indicate contamination by arsenic and manganese in surface water, and by dioxins/ furans, acetone, methyl ethyl ketone, polynuclear aromatic hydrocarbons, arsenic, lead, and zinc in sediments. The site is underlain by a shallow surficial unconfined aquifer. Groundwater flow at the site is likely toward the Roanoke River, where it discharges. Analyses of groundwater samples at the site indicate contamination by arsenic and manganese. Concentrations of some other contaminants such as aluminum, iron, and manganese are above Maximum Contaminant Levels (MCLs). Following an initial review of the RI data, EPA prepared site specific removal action levels of nine constituents of concern and performed a removal action at the site. The removal action consisted of excavation of soil from contaminated grids and ultimately shipping soil, debris, buildings, and tanks offsite. During the removal action, BBL Environmental Service, Inc. personnel, hired by Georgia Pacific, with offices in Cary North Carolina, performed the sampling of the bottom and sides of the· excavations to confirm compliance to site specific removal action levels. The site was then backfilled with clean soil. Based on the results of the RI and considering the removal action data, the following actions are recommended: SPIN 28/EXSUM.WPD ii I I I I I I I I I I I I I I I I I I I • • CDM SPIN 2BIEXSUM.WP0 Executive Summary Remedial action objectives for soil and groundwater contamination at the site should be established based on human health exposure risks, as well as the potential for future contaminant migration from one medium to another (e.g., soils to groundwater). Alternatives for reducing soil and groundwater contamination at the site to achieve the established remedial action objectives should be evaluated, and the most cost-effective alternative for each implemented. iii I I I I I I I I I I I I I I I I I I I CDM List of Acronyms ASTs bis BBLES BRA CERCLA CFR CLP coc core cPAH cy EPA FS HSWA MCL MCLG Above ground storage tanks below land surface Blasland, Bouck & Lee, Engineers and Scientists, Inc.

Contaminants consisting primarily of dioxins/ furans, polynuclear aromatic hydrocarbons (PAHs), pentachlorophenol (PCP), pesticides, polychlorinated biphenyls (PCBs), and a few heavy metals were released into the environment during past sawmill w_ood treating operations. The site was placed on the National Priorities List (NPL) in October of 1999. Having been placed on the NPL, a remedial investigation and feasibility study (RI/ FS) of the Georgia-Pacific Site is thus required as promulgated by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the National Contingency Plan (NCP). The purpose of the RI/FS process is to gather, as quickly and cost-effectively as possible, enough information about the site to support an informed risk management decision regarding which remedy appears to be most appropriate for the site. The RI serves as the mechanism for collecting data to characterize site conditions, determine the nature and extent of the waste, assess risk to human health and the environment, and conduct treatability testing as necessary to evaluate the potential performance and cost of the treatment technologies being considered. The FS s·erves as the mechanism for development, screening, and detailed evaluation of alternative remedial actions. The various steps, or phases, of the RI/ FS process are briefly described below: • • • • SPINB2/SEC1.WPO Scoping-the initial planning phase of the Rl/FS, including the preliminary assessment and site investigation Site Characterization -definition of the nature and extent of contamination, identification of applicable or relevant and appropriate requirements (ARARs), and development of the baseline risk assessment Development and Screening of Alternatives -identification of potential treatment technologies, screening of these technologies, assembly of the technologies into alternatives, and screening of the alternatives Treatability Investigations -bench-or pilot-scale testing to assess the feasibility of a technology 1-1 I I I I I I I I I I I I I I I I I I I CDM Section 1 Introduction • Detailed Analysis of Alternatives -further refinement of the alternatives, analysis of the alternatives with respect to nine evaluation criteria, and comparison of the alternatives against each other. The RI and FS are conducted concurrently so that data collected in the RI influence the development of remedial alternatives in the FS, which in turn affects the data needs and scope of the treatability studies and any additional field investigations. The purpose of this report is to document the results of the RI field investigation performed by EPA for the Georgia-Pacific Site, and provide the information needed to perform a human health and ecological risk assessment assessing the impacts of contamination at the site, and a feasibility study evaluating potential remediation alternatives, if necessary. This document is submitted to EPA in accordance with Work Assignment No. 027-RICO-0401 under Contract No. 68-W5-0022. 1.2 Site Description 1.2.1 Location The Georgia-Pacific Site is located on Plywood Drive within the city limits of Plymouth, Washington County, North Carolina, approximately 0.5 miles east of the downtown district. The geographic coordinates of the site are 35°52' 27" North latitude and 76°44' 27.5" West longitude. 1.2.2 Physical Features The site is approximately 24 acres in size, and is bounded to the north by the Roanoke River, to the west by Atlantic Coast Railroad property, to the east by residential properties, and to the south by the Plymouth High School and the Boy Scouts of America property. A map of the site and surrounding properties is provided in Figure 1-1. The site terrain is flat, low-lying with elevation increasing south of the site. Portions of the site are exposed hard packed dirt, gravel, asphalt, or concrete, while other areas are overgrown with grass, trees, and heavy vegetation. The site is presently unoccupied, and some of the former structures used in the past have been demolished. Recently, the removal action activities further demolished and removed other structures and materials from the site and all that remains is one smoke stack. Figure 1-2 depicts the site layout including all the former structures. As indicated in Figure 1-2, the site has been subdivided into five separate areas to allow for a better description and understanding of former activities at the site. These five areas are described below.

This area was also subsequently used by Outerbanks Contractors for its asphalt mixing plant operations (see Section 1.4). It is bordered to the south by the perimeter drainage ditch; to the north by the former railroad bed spur; and abuts the property boundaries to the east and west. Most of the surface cover in this area is vegetated with a variety of grasses. Significant features in this area include a pre-fabricated metal storage shed erected by Outerbanks Contractors and the access gate to the site from Plywood Road (installed recently by EPA). The area in and around the metal storage shed is the location of several containers (drums, cans, canisters, bags, etc.). Prior to a removal action conducted by the PRPs (see Section 1.8), approximately 200 cubic yards of asphalt stockpiled in numerous piles were located in the center of this area. The asphalt stockpile area was roughly rectangular in shape with dimensions of approximately 260 feet by 230 feet (approximately 1.4 acres). During the removal action, the property owner eliminated approximately 50% of the asphalt piles by recycling the asphalt, and moved tl1e remaining asphalt to the front of the storage shed. Prior to the removal action, two 400-gallon aboveground storage tanks (ASTs), one SOD-gallon AST, and one 2,500-gallon tanker trailer were also located in this area. During the removal action, the two 400-gallon ASTs were removed from the site. The remaining two tanks were left onsite, by request of the property owner, to be recycled later. A septic tank located in the south-central part of this area was also discovered during the removal action and left in place with a piece of concrete placed over the entrance. 1.2.2.2 Former Finished Wood Products Storage/Employee Parking Area This is the area extending from the Roanoke River south to the bed of the former railroad spur where finished wood products were stored and employee vehicles were parked. A portion of this area was also used by Outerbanks Contractors for their asphalt mixing operations. It is bordered to the south by the former railroad spur bed; to the north by the Roanoke River; to the west by the property boundary; and to the east by the Raw Timber Process Area. Most of the surface cover in this area is vegetated with a variety of grasses, shrubs, and saplings. Significant features include the office house located inside the entrance gate from Plywood Road and the pier on the Roanoke River (in the western corner of the site) that was constructed after 1984. Approximately 200 cubic yards of soil stockpiled in two piles are also located at the western margin of this area. The source of the soil is unknown. 1.2.2.3 Former Raw Timber Process Area The Former Raw Timber Process Area is located in the north-central section of the site, extending from the Roanoke River to the former locations of several finished wood product storage sheds and a dry kiln. This area supported the timber process buildings where raw timber logs were debarked, sawed, planed, and (in some instances) surface treated with a liquid anti-stain formulation (dilute SPIN82/SEC1 ,WPO 1-5 I I I I I I I I I I I I I I I I I I I Section 1 Introduction pentachlorophenate to prevent staining from mold and mildew growth) and allowed to dry. It was also used by Outerbanks Contractors for its asphalt mixing plant operations. The area is bordered to the south by the former railroad bed spur; to the north by the Roanoke River; to the east by an intermittent drainage ditch; and to the west by the Former Finished Wood Products Storage/Employee Parking Area. Most of the surface cover in this area is a mix of remnant buildings, foundations, and concrete pads with a dense cover of grasses, shrubs, and trees. Significant features prior to the removal action included a machine shop building, log deck ramp, boiler house and stack, and concrete foundations and storage pads. During the removal action, the boiler house and machine shop were demolished, and most of the demolition debris was transported offsite. Only the machine shop brick was left onsite in this area, at the request of the property owner. Prior to the removal action, one 20,000-gallon AST, and one7,500-gallon tanker trailer were also located in this area. These two tanks were thought to contain petroleum products. During the removal action, the tanker trailer was removed from the site. The remaining 20,000 AST was left onsite, by request of the property owner, to be recycled later. 1.2.2.4 Former Raw Timber Receiving Area The Fonner Raw Timber Receiving Area is located in the easternmost portion of the site where raw timber logs were received and stored prior to processing. This area is bordered to the south by the Former Finished Wood Products Storage Area/Outerbanks Contractors Asphalt Mixing Plant; to the north by the Roanoke River; to the west by the Former Raw Timber Process Area; and abuts the property boundary and perimeter intermittent drainage ditch to the east. Most of this area's surface cover is densely vegetated with a variety of shrubs and trees. 1.2.2.5 Intermittent Drainage Ditches This area is comprised of the following two intermittent drainage ditches: • • Perimeter Intermittent Drainage Ditch -this ditch borders the property boundary from the site access gate on Plywood Road to its confluence with the Roanoke River at the northern corner of the property. This ditch also runs from Plywood Road along the southwest property boundary to the Roanoke River. Raw Timber Process Area Intermittent Drainage Ditch -this ditch extends from the former railroad spur bed to its confluence with the Roanoke River, separating the Raw Timber Process Area from the Raw Timber Receiving Area. 1.2.3 Demography The estimated population within a 4-mile radius of the site is approximately 7,000. The nearest residence is located approximately 700 feet east of the site. The Plymouth High School is located 0.27 miles south of the site. A Boy Scouts of America facility is SPINB2/SEC 1.WPD 1-6 I I I I I I I I I I I I I I I I I I I CDM Section 1 Introduction located adjacent to the Plymouth High School. The land to the north of the site, and immediately north of the.Roanoke River, is classified as wetlands. Access to the site is restricted by a gate; however, there are no fences around the property. A zone of dense woods separates the site from the Plymouth High School, the Boy Scouts of America facility, and residential properties. There has been visual evidence that people trespass onsite and use the docks for recreational fishing in the Roanoke River. 1.2.4 Surrounding Land/Water Use The principal land use in the immediate vicinity of the site is residential and institutional. The citizens of Plymouth have water supplied from one of three sources: the city of Plymouth Public Works Water System, the Washington County system, or private wells. The city and county water supplies are obtained from 4 municipal wells located within 1-2 miles southwest of the site. It is not known how many private or community wells are currently being used within a four-mile radius of the site. There are no surface water intakes located within a fifteen-mile surface water pathway downstream from the site. 1.3 Environmental Setting 1.3.1 Physiography/f opography Washington County, North Carolina lies in the Atlantic Coastal Plain Physiographic Province. This portion of the Atlantic Coastal Plain is primarily characterized by extensive, flat coastal swamps and marshes. Approximately half of the land mass within a four-mile radius of the site is wooded marsh or wetland. The elevation of the site is approximately 5 feet above mean sea level (ms!), and is slightly below 5 feet msl in the nearby wetland areas. Elevations increase to 15 feet msl to the south of the site. 1.3.2 Climate/Meteorology The climatological data for Washington County, North Carolina is representative of the climate in the Plymouth area. Northwestern Washington County has a mean annual precipitation of approximately 50 inches and a mean annual lake evaporation of 41 inches. Therefore, the net annual precipitation is 9 inches. The 2-year, 24-hour rainfall is approximately 4 inches. 1.3.3 Geology The regional geology of Washington County is characterized by complexly interbedded sediments. The sediments are unconsolidated and consist primarily of sand, silt, and clay transported by streams from the adjacent uplands of the Piedmont and Blue Ridge Provinces. The surficial sediments at the site are approximately 25 feet thick, and are underlain by a confining layer which is 25 feet thick. The primary geologic units in the Plymouth area are the Yorktown and Duplin Formations. The Yorktown is generally characterized by fine-grained sands interspersed with varying amounts of silt, clay, and shell beds, and sandy and silty limestones, while the Duplin SPINB2tSEC1 .WPD 1-7 I I I I I I I I I I I I I I I I I I I CDM Formation contains fossiliferous sand, sandy limestone, silty limestone, and calcareous silty sand. Section 1 Introduction The majority of the onsite soil is described as Tarboro sand, while the soil in the adjacent wetlands and the small stream surrounding the property is described as Muckalee loams. Tarboro sand is an excessively drained soil normally found on low broad ridges commonly adjacent to the Roanoke River. The surface layer of this soil is low in organic matter content. Permeability is rapid and the available water capacity is low. The soil is well suited to most urban uses and provides a good support for most structures. The Muckalee loam is a nearly level, poorly drained hydric soil. It is subject to frequent flooding. 1.3.4 Hydrogeology The surficial aquifer in the area of the site is comprised of approximately 25 feet of surficial deposits, underlain by a 25-foot confining layer. Depth to the water table in the surficial aquifer at the site typically varies from 3.5 to 5 feet below land surface (bls). Although no water level measurements have been collected at the site, typical hydrogeology for such a site dictates that groundwater in the surficial aquifer most likely flows toward and discharges into the Roanoke River during normal baseflow conditions in the Roanoke River. The surficial aquifer and the 25-foot confining layer are underlain by 40 feet of sanJ and marl of the Yorktown Formation. The Yorktown Aquifer is a confined aquifer which serves as a major source of water for portions of Washington County. The Yorktown Aquifer is underlain by the confined Pungo Aquifer, which can be reached 90 feet below the land surface. The Yorktown Aquifer is underlain by a 25-foot confining layer. Below this confining layer, the Castle Hayne Aquifer can be reached at a depth of approximately 115 feet bls. The extent of water withdrawal from the aquifers overlying the Castle Hayne in the vicinity of the site is unknown; no groundwater targets have been identified for aquifers in the area other than the Castle Hayne. The Castle Hayne Aquifer serves as the principal source of groundwater in the Plymouth area, and consists of porous and permeable limestone, sandy limestone, and sand. Hydraulic conductivity values in the Castle Hayne Aquifer range from 15 ft/ day to 200 ft/ day. The Castle Hayne Aquifer in the Plymouth area occurs from 150 to 180 feet bls. Recharge to the surficial aquifer is directly from precipitation. Recharge to the underlying groundwater system occurs primarily in the upland interstream areas where the sand layers crop out. Discharge from the system occurs by seepage to streams, estuaries and the ocean. Movement of water from the recharge areas to discharge is controlled primarily by the hydraulic gradients of the dipping beds. 1.3.5 Surface Water Hydrology The site is located immediately to the south of the Roanoke River. The Roanoke River receives surface water from the site through direct runoff, and from several onsite intermittent drainage ditches. The surface water pathway flows in an northeasterly SPINB2/SEC1.WPD 1-8 I I I I I I I I I I I I I I I I I I I CDI\II Section 1 Introduction direction along the Roanoke River for approximately 6 miles, where it flows into the Albemarle Sound. Surface waters in the Albemarle Sound flow eastward towards the Atlantic Ocean for the remainder of the 15-mile surface water pathway. 1.3.6 Wildlife and Natural Resources The Roanoke River is classified as a "Class C" river with an "Sw" supplemental designation. Class C waters are protected for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. A fish consumption advisory has been in effect for a period of years along the lower Roanoke River due to elevated levels of dioxin in fish tissue. There are extensive wetlands around the site; however, there are no known critical habitats of Federally-listed endangered species within the vicinity of the site. There are several endangered and threatened species in Washington County, North Carolina, including the bald eagle as a state and federally-designated endangered species, and the golden eagle and the Waccamaw killifish as state-designated endangered and threatened species. 1.4 Site Operations History The site was originally owned and operated by the Atlas Plywood Company. There is no information regarding Atlas's operations and waste management practices. Georgia-Pacific reportedly bought the facility in 1950, and operated the facility until 1980 employing approximately 400 workers. Site operations involved debarking, sawing, and planing rough hardwood timber from logs.· Surface treatment of some finished lumber took place using a conveyor belt and dip vat. The sawmill facility was permanently closed after a 1983 fire destroyed the sawmill. Georgia-Pacific sold the property to Decatur Partnerships, and the site was leased to Outerbanks Contractors who used a portion of the site as an asphalt mixing plant, employing approximately 10 workers. Allegedly, during the time of the asphalt mixing plant operations, a spill of trichloroethene (TCE) caused by the North Carolina Department of Transportation occurred in the Former Finished Wood Products Storage Area/Outerbanks Contractors Asphalt Mixing Plant area of the site. The amount of the spill was not determined for this report. The entire site is currently unoccupied and inactive. The wood treating process at the site involved passing wood through a dip vat located on a conveyor system, where the wood was surface coated with preservatives and/ or insecticides. After treatment, the wood was reportedly allowed to drip dry directly onto the ground or onto concrete pads before being placed in the lumber storage areas. The dip vat solutions contained pentachlorophenate, sodium metaborate, lindane; and other chlorophenol compounds. Georgia-Pacific's Resource Conservation and Recovery Act (RCRA) Part A Permit Application identified process wastes associated with the facility included spent oil containing metals (D001-ignitable/D007-chromium, D008-lead), spent halogenated degreasing solvents (F00l), spent non-halogenated degreasing solvents (F003/F005), and bottom sediment sludge from the treatment of wastewater from the wood treating process (K00l). The amount of waste generated on a yearly basis by Georgia-Pacific was estimated to be 20,000 pounds of D001/D007/D008 waste, 375 pounds of F001/F003/F005 wastes, and 16,300 pounds of K001 waste. Wastes were either incinerated onsite or transported to the county landfill. SPINB2/SEC1.WPD 1-9 I I I I I I I I I I I I I I I I I I I CDI\II Section 1 Introduction 1.5 Previous Sampling Investigation Results Prior investigations at the site include the Preliminary Assessment conducted by the North Carolina Division of Health Services on December 6, 1985, the Phase I Screening Site Inspection (551) conducted by the NUS Corp. on October 11, 1989, the Phase II 551 conducted by Greenhorne & O'Mara Inc. in September 1991, the Site Inspection Prioritization (SIP) conducted by the Dynamac Corp. on April 15, 1994, and the Expanded Site Inspection (ES!) conducted by the North Carolina Deparhnent of Environment, Health, and Natural Resources in June 1995. Sampling was performed only during the Phase II 551 and the Expanded Site Inspection. During the Phase II SSI, 4 surface soil samples, 2 drainage ditch soil samples, and 3 temporary well point groundwater samples were collected. During the Expanded Site Inspection, 5 surface soil samples, 1 drainage ditch soil sample, and 3 surface water/sediment samples from the Roanoke River were collected. The analytical results from these investigations indicated that onsite soils have been contaminated as a result of past operations. Elevated levels of dioxin/furan isomers, metals, pesticides/PCB's, as well as purgeable and extractable organic compounds were identified in the soils in the dip vat area during both sampling investigations. Elevated levels of many of these compounds were also detected in the sediment samples from the drainage ditches which carry site runoff to the Roanoke River. In addition, the Phase II SSI results indicate that onsite groundwater may have been contaminated with VOCs, pesticides, and metals. However, no groundwater samples were collected during the 1995 ES! to confirm these results. Surface water runoff from the site has resulted in site-related contamination in the Roanoke River. Sediment samples collected during the 1995 ES! indicated the presence of elevated levels of aluminum, arsenic, iron, lead, pentachlorophenol; (3 and/ or 4) methyl phenol, benzo(b/k) fluoranthene, the dioxin/furans congeners 2,3,7,8- tetrachlorodibenzodioxin (TCDD), 1,2,3,7,8-pentachlorodibenzodioxin, 1,2,3,4,7,8- hexachlorodibenzodioxin; octachlorodibenzodioxin, and 2,3,7,8- tetrachlordibenzofuran. 1.6 Nature of Problem As indicated above, many chemicals have been identified as having contaminated various media at the site. Dioxin and pentachlorophenol are two of the principal contaminants found in the onsite surface soil and river sediments. General physical, chemical, and toxicity characteristics of these contaminants are presented below: • Dioxin -Chlorinated dibenzo-p-dioxins are a class of compounds referred to as dioxins. One form of dioxin, TCDD, is the most toxic form of dioxin in humans. It is a colorless solid with no known odor. TCDD does not occur in nature. Exposures to high levels of TCDD can cause chloracne, a severe skin lesion that usually occurs on the head and upper body. There is suggestive evidence that TCDD may cause liver damage, and is suspected of causing cancer. SPINB21SEC1.WPO 1-10 I I I I I I I I I I I I I I I I I I I CDM • Section 1 Introduction Animal studies also suggest that exposure to high levels of dioxin may cause liver.damage in certain species. Exposure can also cause loss of appetite, weight loss, digestive disorders, and death. Dioxin exposure may also result in abnormal reproduction of offspring. Exposure to TCDD has been proven to cause cancer in certain animals. Pentachlorophenol -Pure pentachlorophenol exists as colorless crystals with a very sharp odor when hot, but little odor at room temperature. Pentachlorophenol in impure form can appear dark gray to brown dust, beads, or flakes. Pentachlorophenol does not occur naturally. It is widely used as a wood preservative for power poles, fence posts, lumber, etc. Short-term exposures to pentachlorophenol can reportedly cause harmful effects on the human liver, kidneys, skin, blood, lungs, nervous system, and intestinal tract, and can cause death. The inhalation of the sodium salt of pentachlorophenol by animals has proven to be extremely toxic. Thus, the results of the previous investigations indicate a threat to human health and the environment may exist at the site. However, because the previous investigations did not fully define the nature and extent of the contamination, further site characterization was required to identify and assess the health and environmental concerns related to the exposure route~ substantiated through the previous investigations. 1.7 RI Field Investigation Summary . The primary objective of this RI was to provide the additional data needed to adequately support a baseline human health and ecological risk assessment, and to . provide a basis on which to recommend a subsequent cost-effective remedial action plan, if necessary. Note that this RI focused on all aspects of the Georgia-Pacific Site south of the Roanoke River. Because, the Roanoke River is a large and complex surface water body that may have been affected by many other sites or sources of contamination upstream of the Georgia-Pacific Site, the sampling and analysis of Roa~oke River samples was not included in this RI. Instead, a separate RI is currently being conducted for the Roanoke River which can better address the potential multi- site releases of contamination to this surface water body. The first step in the remedial investigation, after the project plans were developed, was a field investigation. The field investigation included the following tasks: • Soil Sampling - A total of 70 surface soil and 67 subsurface soil samples (not including duplicates) were collected from various locations on-and offsite. The number of soil samples collected from the various areas are as follows: Area Sawmill Plant Area School and Boy Scout Area Residential Areas Surface Soil Samples 55. 7 8 Subsurface Soil Samples 67 0 0 SPINB2JSEC1.WPO 1-11 I I I I I I I I I I I I I I I I I I I CDM • • Section 1 Introduction All of the surface and subsurface soil samples were sent to a CLP laboratory .for complete TCL/T AL analyses, except one. One of the surface soil samples was not analyzed for VOCs. In addition, 60 of the surface soil samples and 19 of the subsurface soil samples were analyzed for dioxins/ furans by a CLP laboratory. Surface Water /Sediment Sampling - A total of 3 surface water and 7 sediment samples (not including duplicates) were collected from the intermittent drainage ditches onsite. All the surface water/sediment samples were sent to a CLP laboratory for complete TCL/TAL analyses. In addition, all the sediment samples were sent to a CLP laboratory for analysis of dioxins/furans. Temporary Well Installation and Groundwater Sampling - A total of 5 temporary shallow monitor wells were installed. Groundwater samples were then collected from these 5 temporary monitor wells, as well as 9 existing shallow monitor wells installed previously at the site. All groundwater samples were sent to a CLP laboratory for complete TCL/TAL analyses. 1.8 Removal Action In August ]999, after the RI field investigation· was completed ,md the analytical results · were received from the CLP laboratories, the PRPs conducted,, removal action at the site under order by EPA to "abate the imminent and substantial endangerment of the public health, welfare, or the environment that may be presented by the actual or threatened release of hazardous substances at or from the site." All the activities conducted during the removal action are described in detail in the Removal Action S11111111an; Report (BBL Environmental Services, 1999, later referred to as BBLES). As indicated in the above sections, two buildings were demolished and three storage tanks were removed from the site during this removal action. The main activity of the removal action, however, was the removal of soil with concentrations of contaminants (as determined frorn the RI sampling investigation data and data collected during the removal action) exceeding the following site-specific removal action levels (SSRALs): '2.cs '1w( • • • • • • • • • 2,3,7,8-TCDD = 1 ug/kg Dioxin expressed as 2,3,7,8-TCDD toxic equivalent quotient= 1 ug/ka_ ____ _ Pentachlorophenol = 25 mg/kg _______________ 3. ___ 1_1 _ Total PAHs = 100,000 ug/kg Total carcinogenic PAHs = 50,000 ug/kg _________ .;......--- Arsenic = 30 mg/kg=---'£_() Chromium (total)= 200 mg/k<kg-;-------------_.;i~y~~~ Chromium VI= 90 mg}~ 2 v v I Lead = 400 mg/i<~g~~~-------------~~/~0D'.:--...,1i,:-\-'.5 Soils exceeding these criteria were excavated and transported offsite to a secure landfill. The excavated areas were then backfilled and compacted to pre-existing grade with clean soil. SPINB2/SEC t .WPD 1-12 I I I I I I I I I I I I I I I I I I I CDM Section 1 Introduction Prior to conducting the soil removal activities, several additional soil samples were collected from specific site areas to better characterize the soil concentrations. In addition, after conducting the soil removal activities and prior to backfilling, several confirmation samples of soils were collected to ensure that all the soil exceeding the removal action levels was removed. The original RI soil sampling data and the subsequent excavated grid confirmation sample data are presented and discussed in Section 2. 1.9 Overview of Report The remainder of this report contains descriptions and results of the sampling activities performed during the RI and the Removal Action. Brief summaries of the remaining sections are presented below: • • • • Sections 2, 3, and 4, discuss the results of the soil, surface water/ sediment, and groundwater sampling investigations, respectively. Each of these sections describes the purpose of the investigation, outlines the methodology for sampling, and summarizes the results of the investigation. Section 5 presents the results of the contaminant fate and transport analysis. Section 6 presents the Quality Assurance Report which summarizes and quantifies the RI analytical data and especially the quality control data. Section 7 summarizes the results of the remedial investigation and presents the conclusions reached based on these results. SPINB21SEC 1.WPD 1-13 I I I I I I I I I I I I I I I I I I CDM Section 2 Soil Sampling Investigation 2.1 Purpose and Scope The amount of pre-remedial investigation data and information accumulated on the GP Site was insufficient to complete a baseline risk assessment to adequately develop a practical and effective remediation plan for the site. In August 1998, the USEP A Region IV SESD prepared a Remedial Investigation (RI) Work Plan to obtain the additional data needed. The Work Plan described the field investigation methods and procedures for collection of onsite and offsite soil for determining the nature of, and the areal and vertical extent of contamination in soils at the site. Upon receipt and review of the analytical results of the RI, EPA determined that a removal action was necessary at the site to address the potential of impact on human health and the environment. Prior to the mobilization of the removal action contractor, EPA established site-specific action levels for nine constituents of concern (COCs) detected in soil and intermittent drainage ditch sediment at the site. These SSRALs are provide_d in Section 1.8 of this report. The RI analytical data were compared to the SSRALs and grids were identitied where the action levels were exceeded. Once a grid was excavated, soil samples were collected to confirm that the remaining soils were below SSRALs. The RI and removal action confirmation analytical data wiH be discussed in the subsequent sections. 2.2 Methods 2,2.1 Remedial Investigation Soil Sampling For the RI field investigation, a grid system was established throughout the GP site property as shown in Figure 2-1. Figure 2-1 also shows the general offsite sampling locations at various residential, school, and Boy Scout properties. Fifty-five grids were used for the onsite sampling. For the surface soil sample collection, one composite sample was prepared by collecting five aliquots within each grid. As stated in the Work Plan, one aliquot was collected from the center of each grid. The four other aliquots were located approximately 35 feet, 60 feet or 85 feet from the center of the grid, based on the grid sizes of 100 by 100 feet, 150 by 150 feet and 200 by 200 feet, respectively, at angles 0°, 90°, 180°, and 270° from north. Some deviations to this sampling procedure were necessary due to conditions encountered at the site. In some grids only the grab sample from the center could be collected and in other grids some of the aliquot locations were not collected or were collected at different grid, based on the grid sizes of 100 by 100 feet, 150 by 150 feet and 200 by 200 feet, respectively, at angles 0°, 90°, 180°, and 270° from north. Some deviations to this sampling procedure were necessary due to conditions encountered at the site. In some grids only the grab sample from the center could be collected and in other grids some of the aliquot locations were not collected or were collected at different locations within a grid other than the distance or angles described above. The surface soil samples were collected from Oto 6 inches below land surface (bis). The samples were analyzed for volatile (VOA) and extractable organic compounds SPIINB21SEC2.WPD 2-1 --- 0 . . n ------ 250' Roanoke River ·' ' ', 5•1 ' . ~j 500' ------- GP-205-SLA ■ ~ SURFACE SOIL SAMPLE LOCATION GRID RIVER TREE LINE RAILROAD -- N gl---------------------------------------------------------1 ~ Georgia-Pacific Hardwoods ! t-_P_ly~m_o_u_t_h_,_N_o_r_t_h __ C_a_r_o_LI_· n_a---i " ~ , 6/02 ,,_ _____________ _. ________________________________ _. .... _____ __, CDl'v1 ,.......,...,,..__., 0nsite Grid and 0ffsile Soil Sampling Locations Figure No. 2-1 - I I I I I I I I I I I I I I I I I I I CDM Section 2 Soil Sampling Investigation (SVOAs), pesticides, polychlorinated biphenyls, metals, dioxins, and dibenzofurans. The VOA soil sample was collected as a grab sample from the center of the grid. For the subsurface soil, a grab sample was collected from the center of each grid at a depth of 18 to 24 inches bis. In addition, subsurface soil samples were collected from grids 25 through 55 at a depth interval of 35 to 42 inches bis. As above, a few of these subsurface soils could not be collected due to subsurface obstructions preventing use of hand augering. Surface soils were also collected at fourteen locations on residential properties adjacent to the site. These samples were collected as a composite of five aliquots and were analyzed for the same constituents as onsite soils. Analysis of RI samples was performed by EPA's contracted laboratories. Data validation of the RI analytical data was performed by Region IV SESD Office of Quality Assurance and Data Integration. 2.2.2 Removal Action Soil Sampling In general, five point aliquot composite samples were collected and the samples were analyzed for the same constituents as the RI data by a laboratory subcontracted by BBLES, Savannah Laboratories and Environmental Services, Inc. in Savannah Georgia. The RI data were compared to SSRALs and the following grids were planned for excavation at the depths given: • Grid 39 -1 foot; • Grid 40 -1 foot; • Grid 41 -2.5 feet; • Grid 44 -2.5 feet; • Grid 46 -4 feet; • Grid 47 - 1 foot; and • Grid 49 -2.5 feet Following the excavation of the grids, one five-point composite sample was collected from the surface of each of the seven excavated grids and these samples were analyzed for the constituents of concern that originally exceeded the SSRAL. The USEPA also collected and analyzed split samples of these confirmation samples collected by BBLES. The BBLES results are presented below following the RI sampling results. 2.3 Summary The analytical results for surface and subsurface soil samples collected onsite and offsite in the residential neighborhood are summarized in Tables 2-1 through 2-4. Table 2-1 presents the volatile and extractable organic constituents detected. Table 2- 2 presents the pesticide and PCBs constituents detected. Table 2-3 presents the dioxins and furans detected. Table 2-4 presents the inorganic constituents detected. Note that for the purpose of summarizing, only chemicals detected at least once in , each medium and their measured concentrations are presented in the summary tables. The complete data set of analytical results for the CLP laboratory analyses performed are provided in Appendix A.

Seven volatile organic constituents were detected with toluene and carbon disulfide being the most prevalent. Toluene was detected only as an estimated value below the detection limit of the analytical method. Carbon disulfide detections ranged from estimated values of 2 to 810 0/ µg/kg. The estimated concentration of 810 µg/kg was detected in GP009SLB. Other (_ carbon disulfide concentrations were significantly lower. Chlorinated volatile organics were detected but were only an estimated concentration below the method detection limit. No areas of significant volatile organic contamination were identified either onsite or offsite based on this data. Extractable Organic Contamination The extractable organic compounds, predominantly the polynuclear aromatic hydrocarbons (PAHs), were extensively detected in surface and subsurface soils throughout onsite and offsite soil. However, most of the detections highlighted in the tables were below the method detection limits and reported as estimated concentrations. Some of the soils contained concentrations of the carcinogenic PAHs (cPAHs) near or an order of magnitude above the detection limits. The highest constituent detected was pyrene at 18,000 µg/kg in the soil sample collected from oL GP044SLB. Samples from GP044SLB, GP046SLB, and GP049SLC all contained PAHs. Offsite locations GP201SLA, GP202SLA, and GP214SLB contained PAHs just below the method detection limit. However, locations GP202SLA (resample) and GP214SLA both contained a signficant level of PAHs with the highest concentration 7:1 of fluorene at 9100 µg/kg in GP214SLA. Figure 2-2 shows the depth intervals and concentrations of P AHs and cP AHs detected above the method detection limits for onsite soils. Figure 2-3 shows the concentrations of PAHs and cPAHs detected above the method detection limits for offsite surface soils. Figure 2-2 shows the areas of the site as potential areas of significant PAH contamination. These areas were typically located in former process areas centrally located on the Georgia-Pacific property. The lateral extent of the PAH contamination was not significant beyond the site property. However, as Figure 2-3 shows, there were areas offsite which had low PAH contamination.

Downward migration of PAHs into the shallow groundwater could have occurred since some of the subsurface samples collected showed PAH contamination. See section 4 for the discussion of PAHs in groundwater. Prior to initiating the removal action, the PAH analytical data were compared to the SSRALs established for the site. Only Grid 44 exceeded the SSRAL for Total PAH. The SSRAL for cPAHs was also nearly exceeded in Grid 44. The SSRAL for Total 1r-V \ 7G-o, PAHs was 100,000 ug/kg and 50,000 ug/kg for Total cPAH. ~ o~c;"'-~ . ~'.:/. .:i~ Pesticides and Polychlorinated biphenyls • ·,;. ()P .-.. Trace levels of chlorinated pesticides were detected in the onsite and off site soil.· The. l' . most frequently detected pesticide was 4,4'-DDT with the highest concentration °" reported as 69 µg/kg in GP019SLA. However, PCBs mixtures were _ ,l.. detected at significant levels in several samples collected onsite. None of the off site \p ti" soil contained PCBs. Aroclors 1254 and 1260 were the only PCBs detected with the o.. highest concentration being 13,000 µg/ kg of Aroclor 1254 in GP046SLC. Also noteworthy was that the level of Aroclor 1254 at this location increased as sample depth increased. (GP046SLA-410 µg/kg, GP046SLB-3300 µg/kg, and GP046SLC- 13,000 µg/ kg. Groundwater is just below the SLC sample depth. The next highest concentration of Aroclor 1254 was detected in GP017SLB. However the 3200 µg/kg". of Aroclor 1254 was not detected in the duplicate from the same sample location and depth. The highest concentration of Aroclor 1260 was detected in GP044SLB at 2,800 µg/kg. Figure 2-4 shows the depths and concentrations of PCBs detected above the method detection limits for onsite soils. Contaminant levels of pesticides and/ or PCBs did not reveal any significant source areas on or off the site. However, Grid 46 PCB concentration did increase with depth which would indicate a downward migration into the shallow groundwater. See section 4 for discussion of groundwater sample analysis in or near Grid 46. Dioxin/Furan Chemical Contamination Varying concentrations of dioxins and furans were detected in all the samples collected both at the surface and in the subsurface soil. This was for both onsite and offsite sample locations. Octachlorodibenzodioxin (OCDD) was the most frequently detected dioxin and had the highest concentrations. The highest OCDD was detected in the sample collected from GP040SLA and reported as 10,000,000 ng/kg (equivalent to 10,000 µg/kg). Other dioxins and furans were also reported in the sample from GP040SLA and the toxic equivalent value (TEQ) was estimated at 27,000 ng/kg. The TEQ is calculated to normalize the toxicity of the detected dioxin-like compounds to the toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most widely studied and most toxic of the dioxins. Each dioxin-like compound is assigned a toxic equivalence factor (TEF) as defined in Interim Procedures for Estimating Risks Associated with Exposures to Mixtures of C/1/orinated Dibenzo-p-dioxins and Dibenzofurans (CDDs and CDFs) and 1989 Update (EPA, 1989). The TEQ is the sum of the concentrations of the dioxin-like compounds multiplied by their respective TEFs.

The other grids which contained notable concentrations of dioxins and furans included: GP037, GP039, GP041, GP046, GP047, and GP051. Samples collected from GP046 showed TEQ increasing as samples were collected deeper from 11 ng/ kg in the GP046SLA, 97 ng/ kg in the GP046SLB, and to 1300 ng/kg in the GP046SLC. These concentrations were estimated. However, the TEQ concentrations decreased with increasing depth in the three sample intervals from GP041, GP051, and GP053. Figure 2-5 shows the TEQ values for the surface soil locations where the TEQ was greater than 100 ng/ kg. Figure 2-6 shows the TEQ values for the subsurface soil locations where the TEQ was greater than 10 ng/kg. The samples collected in the neighborhood contained dioxins and furans. The TEQ concentrations in the neighborhood ranged from non-detected (quantitation limit of 1.9 ng/kg) to 36 ng/kg. The sample from GP205SLA contained the highest TEQ of 36 ng/kg and the highest concentration of OCDD of 27,000 ng/kg. The analytical data and Figures 2-5 and 2-6 show the general areas of dioxin and furan contamination potentially occurring from source areas on the site. Other dioxin and furan concentrations were below the site source area levels. In addition no significant downward migration is evident in the data collected. Grids 40 and 41 were selected for excavation during the removal action due to exceedance of the TEQ of 1 µg/kg (1,000 ng/kg) SSRAL. See the Post Removal Data discussion below for further discussion of the selection of grids requiring excavation.

Aluminum was the other metal detected at a significant concentration however was similar to offsite concentrations. ~Cf'" Other metals were detected at higher concentrations at individual grid locations \ compared to the site average concentrations. Arsenic was detected in grid sample ' GP049SLA at a concentration of 59 mg/kg and at a concentration of 83 mg/kg in GP049SLB. The highest concentration of arsenic detected in an off site location was an estimated concentration of 18 mg/ kg at GP202SLA. Barium was detected in GP049SLC at a concentration of 2,200 mg/kg, whereas the highest concentration of I'../ !,ii~;,, barium detected off site was 120 mg/kg in GP206SLA. Chromium_ was detected at 270 -0: \O\~ mg/kg in GP039SLA whereas the average concentration of chromium including offsite was less than 15 mg/kg. The highest concentration of copper was also ~'o NJ~. detected in GP039SLA at 260mg/kg. Lead was detected in GP046SLC at an estimated :.------"'Ii' concentration of 3,300mg/kg and in GP202SLA (offsite) at an estimated concentration of 2,300 mg/kg. The lead concentration increased with depth for the samples collected in grid GP046. The majority of soil samples collected onsite and offsite contained lead concentrations less than about 50 mg/kg. The highest magnesium concentration was detected onsite in GP056SLA at 9,500 mg/kg. Another metal with a significant high concentration was zinc, which was detected in GP046SLC at an estimated concentration of 1,000 mg/kg. At this sample location the zinc concentration increased as the depth increased which is similar to the lead concentration also at this location. In addition, zinc was detected in GP049SLA, GP049SLB, and GP049SLC at concentrations of 900, 840, and 900 mg/kg, respectively. Most of the other soil samples both onsite and off site contained zinc concentrations less than 100 mg/kg. Figure 2-7 shows the onsite sampling grids with the highest detections of metals other than the nutrient metals.

Elevated concentrations of dioxins, furans, (expressed as TEQ), metals, or P AHs were compared to the SSRALs established by the EPA. Metals, dioxins, furans, or PAHs were evident as the primary contaminants in grids 39, 40, 41, 44, 46, 47, and 49. These grids were selected for excavation along with an area along the southern portion of the site which was formerly the asphalt mixing plant. However, later focused sampling of the areas of the former asphalt mixing plant did not reveal any contamination exceeding the site specific removal action levels. A more detailed discussion of the reasoning and methods for resampling these grids was provided in the Removal Action Summan; Report. Following the excavation and offsite disposal of the soil, samples were collected from the bottom of the excavations to confirm the adequate removal of the contaminants. For grids 1, 2, and 3, only the arsenic concentration from the RI data slightly exceeded the SSRALs. Upon recommendation by Georgia-Pacific and concurrence by EPA these grids were resampled prior to the removal action. Table 2-5 above provides a confirmation that the targeted constituents were removed. SPIINB2/SEC2.WPD 2-88 I I I I I I I I I I I I I I I I I I CDM I I Sec3.wpd Section 3 Surface Water/Sediment Sampling Investigation 3.1 Purpose and Scope Surface water and sediment sampling were conducted in the intermittent drainage ditches located onsite to determine the nature and extent of contamination in these areas. Three surface water and seven sediment samples were collected from the drainage ditches. The locations of all the surface water and sediment samples are shown on Figure 3-1. Note that it was intended for both a surface water and a sediment sample to be collected from each sampling location. In four locations, however, there was insufficient surface water to collect samples. 3.2 Methods All surface water and sediment samples collected were grab samples and were collected according to the procedures established in the Remedial Investigation Work Plan (EPA, 1998) for the Georgia Pacific Site, and Section 4 of EPA's E11viro11111ental Investigations Standard Operating Procedures and QualihJ Assurance Manual (EPA, 1996). The surface water samples were collected from several inches below the air-water interface and sent to a CLP laboratory for analysis of all TCL/TAL constituents. Sediment samples were collected from the zero-to three-inch interval below the water-sediment interface and sent to a CLP laboratory for analysis of all TCL/T AL constituents as well as for dioxin/ furan analysis. 3.3 Summary The analytical results for the surface water and sediment samples collected at the site are summarized in Tables 3-1 (surface water), and Tables 3-2 through 3-4 (sediment). Note that for the purpose of summarizing, only chemicals detected at least once in each medium and their measured concentrations are presented in the summary tables. The complete data set of analytical results for the CLP laboratory analyses performed are provided in Appendix A. In the summary tables, those concentrations considered to reflect a valid detection of unnatural contamination are printed in bold italicized text to distinguish them from the other measurements. Since organic chemicals are not believed to be naturally occurring in surface water, any detection of an organic chemical in surface water is considered to be unnatural contamination. The same is true for sediments. For the inorganics in both surface water and sediments, since no background surface water or sediment samples were collected at the site, the concentrations were compared to typical background concentrations at other North Carolina sites in an attempt to distinguish unnatural contamination from natural chemical concentrations. 3-1 I I I I I I I I I I I I I I I I I Roonoke River 0 300' ---600' Georgia-Pacific Hardwoods 1 .......

The spectrum of chemicals detected in at least one surface water sample from this area included only one volatile organic and 11 inorganics. Volatile Organic Contamination Volatile organic chemical contamination in surface water appears to be relatively insignificant. The only voe detected in surface water was acetone and it was detected in only one surface water sample (SW-7) at a concentration of 160 ug/1. SW- 7 is located in the northeastern part of the perimeter drainage ditch near the Roanoke River. Inorganic Chemical Contamination As indicated in Table 3-1, of the 11 inorganic chemicals detected in surface water at the site, only two appear to be at concentrations which are clearly indicative of unnatural contamination. These two chemicals, arsenic and manganese, were detected at concentrations significantly above typical background concentrations in at least two of the three surface water samples collected. The areal distribution of the arsenic and manganese contamination found in surface water in this remedial investigation is shown in Figure 3-2. 3.3.2 Sediment As indicated in Tables 3-2 through 3-4, a wide variety of chemicals were detected in the sediment samples collected at the site. The spectrum of chemicals detected in at least one sediment sample from this area included 17 dioxins/ fur~ns, 2 volatile organics, 14 extractable organics, 4 pesticides, and 14 inorganics. Sediments were only sampled at the surface to evaluate the potential for direct contact exposure to human or ecological receptors. Dioxin/Furan Chemical Contamination As indicated in Table 3-2, numerous dioxins/ furans were found at concentrations which appear to be significantly above typical background concentrations in all the sediment samples except SD-5 and SD-6. The TEQ for the dioxins/furans measured in the sediments ranged from 9.9 ng/kg to 850 ng/kg. (See section 2.3 Dioxin/Furan Chemical Contamination for an explanation of TEQ.) The areal distribution of the dioxin/furan contamination (as indicated by TEQ calculations) found in sediments in this remedial investigation is shown in Figure 3-3. Volatile Organic Chemical Contamination As indicated in Table 3-3, only two VOCs were detected in any of the sediment samples: acetone and methyl ethyl ketone. Acetone was found in 4 of the 7 sediment samples at concentrations ranging from 350 ug/kg to 2800 ug/kg. Methyl ethyl ketone was found in 3 of the 7 sediment samples at concentrations ranging from 84 ug/kg to 440 ug/kg. The areal distribution of the voe contamination found in sediments in this remedial investigation is shown in Figure 3-4. 3-7 I I I I I I I I I I I I I I I I I I Roanoke River \ \ OfflCE \HOUSE ,0 _, N ~STACKS \ SW-OJ 1 4 .a.

All 14 of the extractable organics detected in sediments are PAHs, and at 50-1, all 14 PAHs were detected with concentrations ranging from 240 to 5600 ug/kg. The carcinogenic PAH concentrations in the 50-1 sediment sample range from 540 ug/kg to 4400 ug/kg. The total PAH concentration measured in sediment sample 50-1 is 31,500 ug/kg while the total carcinogenic PAH concentration measured is 13,840 ug/kg. A few PAHs were also detected in sediment samples 50-3, 50-6, and 50-7, but at relatively low concentrations (ranging from 71 ug/ kg to 350 ug/ kg), and none of the P AHs detected in these samples are carcinogenic. The areal distribution of the extractable organic chemical contamination (as indicated by total PAH and total cPAH cakulations) found in sediments in this remedial investigation is shown in Figure 3-5. The subsurface sediments were not sampled because of the reason of evaluating only direct contact exposure to human or ecological receptors. Pesticide Chemical Contamination Pesticide chemical contamination in sediments at the site appears to be relatively insignificant. Three of the four pesticides detected are 4,4-O0X chemicals (4,4-000, 4,4-OOE, and 4,4-OOT), and they were found in only one sediment sample (SO-2) at concentrations ranging from 190 ug/kg to 540 ug/kg. Likewise, the fourth pesticide detected (Endosulfan II) was found in only one sediment sample (5D-1) at a concentration of 6.1 ug/kg. 50-2 is located in'the southwestern part of the perimeter drainage ditch near the entrance gate, while 50-1 is located in the northwestern part of the perimeter drainage ditch near the Roanoke River. Inorganic Chemical Contamination As indicated in Table 3-4, of the 14 inorganic chemicals detected in sediments at the site, only five appear to be at concentrations which are clearly indicative of unnatural contamination. Three of these five chemicals (arsenic, lead, and zinc) were detected at concentrations significantly above typical background concentrations in several of the sediment samples. The other two chemicals (barium and iron) were detected at concentrations significantly above typical background concentrations in only one sediment sample (S0-2). The areal distribution of the arsenic, lead, and zinc contamination found in sediments in this remedial investigation is shown in Figure 3-6. The arsenic and zinc contamination in sediments appears to be spread throughout most of the length of the intermittent drainage ditches, having been detected at elevated concentrations in 50-1, 50-2, 50-3, 5D-4, and 5D-7. The detected concentrations of arsenic ranged from 3.7 mg/kg to 300 mg/kg, while the detected concentrations of zinc ranged from 12 mg/kg to 340 mg/kg. The drainage ditch areas considered to be contaminated with arsenic and zinc include the western, southwestern, and northeastern segments of the perimeter drainage ditch. The lead contamination also appears to be spread throughout much of the length of the intermittent drainage ditches, having been detected at elevated concentrations in 50- 1, 50-2, 5D-3, and 50-4. The detected concentrations of lead ranged from 5.7 mg/ kg to 140 mg/kg. The drainage ditch areas considered to be contaminated with lead include the western and southwestern segments of the perimeter drainage ditch. 3-11 I I I I I I I I I I I I I I I I I I I 0 -- Roanoke River 300' -600' Georgia-Pacific Hardwoods J Pl mouth, North Carolina / / LEGEND: S0-1 ® ~ N SEDIMENT SAMPLE LOCATION PAH CONCENTRATION (ug/kg) cPAH CONC-ENTRATION (ug/kg) ND NON DETECT -· · · -RIVER EDGE ~ TREE LINE PROPERTY BOUNDARY INTERMITTENT DRAINAGE DITCH MARSHY AREA PAH Contaminant Distribution in Sediment Figure No. 3-5 2 a»JI ~~----~_--_~_·•-_•-·_-·_·-___ ....., _____________ ...__s..;./_o_o__. • I I I I I I I I I I I I I I I I I I I 0 - Roanoke River 300' - fSTACKS 600' Georgia-Pacific Hardwoods a Pl mouth, North Carolina Qi-,.....;.~=~~---------1 / / LEGEND: 50-1 @ N SEDIMENT SAMPLE LOCATION ARSENIC CONCENTRATION (mg/kg} LEAD CONCENTRATION (mg/kg) ZINC CONCENTRATION (mg/kg) ND NON DETECT -· · · -RIVER EDGE ~ TREE LINE PROPERTY BOUNDARY INTERMITTENT DRAINAGE DITCH MARSHY AREA Figure No. 3-6 Inorganic Contaminant Distribution in Sediment la..... __ ~_=D_!!' __ ·•_-_•-_·-•--___ ..._ __________ ___.,_s;_o_o ......

A total of five temporary well points were installed at the approximate locations shown in Figure 4-1 to supplement the nine existing monitor wells installed previously at the site (also shown in Figure 4-1) prior to this remedial investigation. Note that the nine existing monitor wells were all constructed with 2-inch diameter PVC. 4.2 Methods One groundwater sample was collected from each of the five temporary well points and the nine existing monitor wells identified above. These samples were sent to a CLP laboratory for complete TCL/TAL analyses. Just prior to sampling of each monitor well, field measurements of the well depth, depth to water, groundwater temperature, pH, conductivity, and turbidity were taken, and the results are provided in Table 4-1. All groundwater samples collected were grab samples and were collected according to the procedures established in the Remedial Investigation Work Plan (EPA, 1998) for the Georgia Pacific Site, and Section 4 of EPA's Environmental Investigations Standard Operating Procedures and Qualihj Assurance Manual (EPA, 1996). 4.3 Summary The concentrations of chemicals detected in the groundwater samples collected at the site are summarized in Table 4-2. Note that for the purpose of summarizing, only chemicals detected at least once in groundwater and their measured concentrations are presented in the summary table. Complete analytical results for the CLP laboratory analyses performed are provided in Appendix A. In Table 4-2, those concentrations considered to reflect a valid detection of unnatural contamination are printed in bold italicized text to distinguish them from the other measurements. Since organic chemicals are not believed to be naturally occurring in groundwater in this area, any detection of an organic chemical was considered to be unnatural contamination. For the inorganics, since no background groundwater samples were collected at the site, the concentrations were compared to typical background concentrations at other North Carolina sites in an attempt to distinguish unnatural contamination from natural chemical concentrations. As indicated in Table 4-2, a wide variety of chemicals were detected in the groundwater samples collected at the site. The spectrum of chemicals detected in at least one groundwater sample from this area included one volatile organic, five extractable organics, and 15 inorganics.

The only VOC detected in groundwater was toluene and it was detected in only one monitor well (MW-1) at an estimated concentration of 1 ug/1. MW-1 is located in the Former Raw Timber Processing Area. Note that no VOCs were detected in any of the monitor wells located in or near the alleged TCE spill area. Extractable Organic Chemical Contamination Extractable organic chemical contamination in groundwater at the site is also relatively insignificant. The five extractable organics detected are all PAHs, and they were detected in only one well (TW-54) at concentrations ranging from only 1 ug/1 to 3 ug/1. TW-54 is located near the Roanoke River in the Former Raw Timber Receiving Area. It should be noted that when well point TW-54 was installed, the drillers experienced an extremely strong creosote odor emanating from the hole and soils after drilling to a depth of 5 feet. Inorganic Chemical Contamination As indicated in Table 4-2, of the 15 inorganic chemicals detected in groundwater at the site, only two appear to be at concentrations which are clearly indicative of unnatural contamination. These two chemicals, arsenic and manganese, were detected at concentrations significantly above typical background concentrations in several wells. The areal distribution of the arsenic and manganese contamination found in groundwater in this remedial investigation is shown in Figure 4-2. Some of the other inorganics detected (i.e., aluminum, chromium, cobalt, copper, lead, vanadium, and zinc) were found at slightly elevate1 concentrations in well points TW-49 and TW-54 when compared to the other wells onsite, but the concentrations measured in these samples are within the realm of possible background concentrations, particularly when considering the high turbidity of the TW-49 sample and the potential high turbidity of the TW-54 sample. The turbidity of the sample from TW-54 was not measured, but well point samples typically are very turbid due to the inability to develop a well point. The arsenic contamination in groundwater appears to be spread throughout much of the site, having been detected at elevated concentrations in MW-1, MW-3, MW-4, MW-7, MW-8, MW-9, TW-24, TW-29, TW-49, and TW-54. The detected concentrations of arsenic ranged from an estimated 5 ug/1 to 990 ug/1. The highest concentration of arsenic was found in the area of the alleged TCE spill, but other high concentrations of arsenic (above its 50 ug/1 MCL) were also found in the Former Raw Timber Processing Area (MW-1) and the eastern part of the Former Finished Wood Products Storage Area/Outerbanks Contractors Asphalt Mixing Plant Area (MW-3 and TW-29). The manganese contamination appears to be concentrated in the Former Finished Wood Products Storage Area/Outerbanks Contractors Asphalt Mixing Plant Area, having been detected at elevated concentrations in MW-3, MW-4, MW-7, and TW-29. The detected concentrations of manganese ranged from 62 ug/1 to 4700 ug/1.

Some subsurface soil descriptions were recorded during the installation of the temporary well points installed during this RI. Four descriptions from temporary well points; TMW-29, TMW-49, TMW-54, and TMW-24 were recorded in the logbook. The lithologic descriptions and associated depths were basically the same and included the following. Surface to 1-foot varied depending on the area and consisted of asphalt, concrete, gravelly debris, or brown soil. Gray sand was typical encountered from 1 to 9 or 10 feet. Water was encountered at 6-feet at TMW-54 (nearest the river) and 8-feet on the others. These temporary well points did not go any deeper than 10 feet below land surface. Depth to water was·measured on all the existing monitor wells before sampling as provided on Table 4-1 above. A groundwater potentiometric map could not be generated since well casing elevations above mean sea level were not available for the site. However, based on the topography, the shallow water levels recorded, and the existence of the Roanoke River adjacent to the site, it may be assumed that the shallow groundwater flow is influenced by and likely flows toward the river. SPINB2/SEC4.WPD 4-8 I I I I I I I I I I I I I I I I I I I CDM SPIN2B/SECT5 Section 5 Contaminant Fate and Transport Analysis An evaluation of the environmental fate and transport of site-related contaminants is important in determining the potential for exposure to the contaminants. There are several mechanisms by which contaminants may migrate at the Georgia Pacific Site. Migration into the air can occur via volatilization or dust generation. Migration into groundwater can occur by percolation of infiltrating rainwater or groundwater flow through waste materials or contaminated soils. Transport to surface waters can occur via surface water runoff, and/ or through groundwater discharge. The mechanisms of migration for the contaminants of concern detected at the site (see Section 6) are discussed in more detail below. Estimates of the physical and chemical properties of the contaminants of concern which may affect contaminant migration are presented in Table 5-1. Note that the properties for the dioxins/ furans are represented by the properties of 2,3,7,8-TCDD (one particular dioxin) in Table 5-1. Some variation in properties is expected between each of the individual dioxins and furans, but the variations are not expected to be significant. The general persistence of the contaminants of concern is also discussed below. 5.1 Contaminant Migration 5.1.1 Air Migration Generally, volatilization from soil and/ or water into air may be an important transport mechanism for the organic chemicals with Henry's Law Constants greater than 10·5 atrn-m3 / mole and molecular weights less than 200 g/ mole. None of the organic contaminants of concern found at the site meet these criteria, and thus, volatilization of the contaminants of concern is not considered an important release mechanism at this site. Fugitive dust emissions from wind or mechanical disturbances may occur from unpaved or unvegetated areas of the site. The environmental factors that influence wind erosion are wind speed, moisture content, vegetative cover, and soil composition. Because the environmental factors at the Georgia Pacific Site are at times and places conducive to wind erosion, each of the contaminants of concern detected in surface soil is susceptible to migration via fugitive dust generation. 5.1.2 Surface Water Migration Contaminant migration into the Roanoke River, a major surface water body at the Georgia Pacific Site, may occur through surface water runoff, and/ or through groundwater discharge. Upon reaching this surface water pathway, contaminants may remain in the water column, volatilize, or sorb to bottom or suspended sediments. Volatile organic contaminants tend to quickly volatilize into the atmosphere upon reaching surface waters and for this reason are rarely observed at detectable concentrations in surface water samples. Nevertheless, even though there are no volatile organic contaminants of concern at the site, it should be noted that during this RI, one volatile organic chemical (acetone) was detected in both surface water and sediment samples collected from the intermittent drainage ditches which lead to the Roanoke River. 5-1 TABLES-1 Section 5 Contaminant Fate and Transport ESTIMATED PHYSICAL AND CHEMICAL PROPERTIES OF THE CONT AMIN ANTS OF CONCERN GEORGIA-PACIFIC SITE Contaminant of Concern Inorganics Aluminum Arsenic Barium Chromium Iron Lead Manganese Vanadium Molecular Weight (g/mol) NA NA NA NA NA NA NA NA Extractable Organics Benzo(a)anthracene 2281 Benzo(b &/ or k)fluoranthene2521 Benzo-a-pyrene 2521 Dibenzo(a,h)anthracene 2781 Indeno(l,2,3-cd)pyrene 2761 Other Organics PCB-1254 PCB-1260 2,3,7,8-TCDD (Dioxin) 3271 3701 3221 PLYMOUTH, NORTH CAROLINA Solubility at 25° C (mg/I) NA NA NA NA NA NA NA NA 0.0142 0.000552 0.00382 0.00052 0.622 0.0122 0.00272 0.21 Henry's Constant K0, (atm-m3/mol x 10-5 ) (ml/g) NA NA NA NA NA NA NA NA 0.0661 1.21 0.241 0.000731 ·3.0 X 10-15 1 2301 7101 5.4 X 10-18 l NA NA NA NA NA NA NA NA 1,400,0001 550,0001 400,0001 1,700,0001 31,000,0001 400,0001 2,600,0001 4,600,0001 NA NA NA NA NA NA NA NA 140,0002 3,700,0002 1,100,0002 930,0002 46,000,0002 1,100,0002 14,000,0002 2,000,0001 Kd (ml/ g) 2004 0.54 304 S004 16,0004 7504 5303 14,0003 42003 35003 170,0003 42003 53,0003 76003 TABLE 5-1 (cont.)

(1990) I • I I I I B I I I I I I I I I I I CDM I SPIN28/SECTS Section 5 Contaminant Fate and Transport The dioxins/ furans and other organics with low water solubilities and high Koc values such as PAHs, pesticides, and PCBs will tend to associate with sediments as opposed to volatile organics and extractable organics with high water solubilities and low Koc values, which tend to stay in the water column. All the organic contaminants of concern at this site have low water solubilities and high K0, values and based on the surface water and sediment sample results obtained in this remedial investigation, it appears that these contaminants are mostly sorbing to sediment particles, as expected. This does not preclude the migration of these contaminants to the Roanoke River, however, as the contaminated sediments may be conveyed to and within the Roanoke River via sediment transport mechanisms during storm events. The behavior of the inorganic contaminants of concern in surface water is affected by pH, temperature, and hardness. Inorganic compounds can occur in aquatic systems as dissolved ions, dissolved complexes with organic and inorganic chemicals, colloids, or particulates. The solubility and mobility of the metal inorganic contaminants is enhanced by their ability to form complexes with humic and fulvic acids, carbonates, hydroxides, and phosphates. Based on the surface water and sediment sample results obtained in this remedial investigation, it appears that several inorganic chemicals are migrating to surface waters at the site, and that the geochemical processes in the surface waters allow for some of these contaminants to both remain in the water column and sorb to sediments, while others are mostly sorbed to sediment particles. Again, however, the sorbing of contaminants to sediment particles does not preclude the migration of these contaminants to the Roanoke River, as the contaminated sediments may be still be conveyed to and within the Roanoke River via sediment transport mechanisms during storm events. 5.1.3 Soil Migration Contaminants present in surface and subsurface soils may leach to the underlying aquifer. Many factors influence the rate of contaminant movement through soils. These include the physical/ chemical properties of the contaminants (e.g., solubility, density, viscosity, K0,, K0w), and the physical/ chemical properties of the environment (e.g., rainfall percolation rate, soil permeability, porosity, particle size distribution, organic carbon content). Because all these factors can affect the rate of contaminant movement through soils, it is very difficult to predict such movement. However, based on the data collected in this remedial investigation some gross generalizations of this movement can be made. Sorption of a chemical to soil particles is the only significant hinderance of contaminant migration in soils at the Georgia Pacific Site. If it were not for sorption, rainfall recharge and soil permeability at this site are high enough such that all the contaminants of concern would readily move through the soils. Sorption of contaminants is generally described by their distribution coefficients (Kctl• The distribution coefficient can be expressed as: mass of contaminant on the solid phase per mass of solid phase concentration of solute in solution 5-4 I I I I H I I I I I I I I I I I I I CDM I SPIN2B/SECTS Section 5 Contaminant Fate and Transport As indicated in Table 5-1, all the organic contaminants of concern at this site have very high Ka values and even though they have been observed in the soils and sediments at significant concentrations, they have not been observed in groundwater. Sorption of these contaminants of concern to the soils at the site has apparently prevented significant migration into groundwater. Except for barium (and possibly aluminum and vanadium), the inorganic contaminants of concern also have high K" values, and thus, these contaminants will also readily sorb to soil particles at the site. However, the observance of some of these inorganic contaminants (i.e., arsenic and manganese) in groundwater at significant concentrations indicates that the abundance of these contaminants in soil may be too high for complete sorption to occur. The concentrations of the inorganics in the soils is apparently high enough such that a significant amount of this inorganic contamination can still leach into groundwater. Nevertheless, except for barium (and possibly aluminum and vanadium), movement of the inorganic contaminants of concern in the soils at this site is expected to be very slow due to their high propensity for sorption. 5.1.4 Groundwater Migration Many factors influence the rate of contaminant movement in an aquifer system. These include the physical/ chemical properties of the contaminants (e.g., solubility, density, viscosity, etc.), and the physical/ chemical properties of the environment (e.g., soil permeability, porosity, bulk density, particle size distribution, extent and connectivity of fractures, etc.). Because all these factors can affect the rate of contaminant movement through aquifers, it is very difficult to predict such movement. However, based on the data collected in this RI, some gross approximations of this movement can be made. Once the contaminants of concern reach groundwater, they will generally move as groundwater moves, through the process of advection. However, the process of dispersion will also cause the contaminants to spread both horizontally and vertically. Dispersion generally causes contaminants to migrate (spread) 10 to 20 percent farther than-migration created by advection alone. Counteractive to the advection and dispersion processes, however, is the process of sorption which will retard the movement of the contaminants. Estimates of the distribution coefficients for the contaminants of concern at the site are presented in Table 5-1. As indicated in this table, the majority of the inorganic contaminants of concern and all of the organic contaminants of concern have relatively high Ka values, and thus, these contaminants will readily sorb to soil particles at the site and are essentially immobile. Barium and possibly a few other inorganic contaminants of concern, however, generally have lower K" values, and thus will not sorb to soil particles as readily as the other contaminants of concern. These contaminants are therefore considered to be mobile, and will generally move as groundwater moves, only at reduced velocities. Furthermore, since groundwater most likely moves toward the Roanoke River, these mobile contaminants will also migrate toward the Roanoke River where, eventually, they will be discharged. 5-5 I I I I I I I I I I I I I I I I I I CDM I SP1N2B/SECT5 Section 5 Contaminant Fate and Transport 5.2 Contaminant Persistence Persistence is the measure of how long a chemical will exist in the environment before it degrades or transforms, either chemically or biologically, into some other chemical. Some of the factors which affect the persistence of a chemical include the state of the chemical, the availability of the chemical, exposure to sunlight, oxygen availability, the types and quantities of microorganisms present, availability of nutrients, temperature, pH, as well as the presence of other chemicals which may inhibit or enhance degradation. Usually, persistence is expressed in terms of a chemical half-life and can be on the order of days, weeks, or years. Because of the many complex factors which may affect persistence, the actual rate of chemical degradation is very difficult to predict for a given chemical at a given site, especially without the benefit of any degradation data collected from site-specific field studies. However, a qualitative evaluation of the potential for degradation of a chemical can be made based on the results of laboratory and/ or field studies conducted previously at other locations. Such a qualitative evaluation was conducted for the contaminants of concern detected at the Georgia Pacific Site, and the results are summarized in Table 5-2. Again, note that the degradation potential for the dioxins/furans are represented by the degradation potential for 2,3,7,8-TCDD in Table 5-2. Some variation in the degradation potential is expected between each' of the individual dioxins and furans, but the variations are not expected to be significant. In this table, the degradation potential for each of the contaminants of concern is indicated for the following three environmental media categories: • • • Atmospheric Degradation - A chemical released to the atmosphere may degrade by such processes as photolysis and/or reactions with the hydroxyl radical, ozone, or other chemicals present. Aquatic Degradation - A chemical released to fresh, marine, or estuarine surface waters may degrade by such processes as photolysis, hydrolysis, oxidation, and/ or biodegradation. Terrestrial Degradation - A chemical released to soil or groundwater may degrade by such processes as hydrolysis, oxidation, and/or biodegradation. As indicated in Table 5-2, of all the contaminants of concern at the Georgia Pacific Site, the metals have the least potential to degrade in all media and therefore will likely persist the longest at the site. In fact, these contaminants, under ordinary conditions, will likely persist indefinitely (for all practicable purposes). Other chemicals which also have low degradation potential include the PCBs. All the other contaminants of concern (i.e., the dioxins/ furans and the PAHs) generally have low to moderate potentials for degradation, unless released to the atmosphere, in which case all the PAHs generally have a high potential for degradation. 5-6 TABLES-2 Section 5 Contaminant Fate and Transport ESTIMATED DEGRADATION POTENTIAL OF THE CONTAMINANTS OF CONCERN' GEORGIA-PACIFIC SITE Contaminant of Concern lnorganics Aluminum Arsenic Barium Chromium Iron Lead Manganese Vanadium Extractable Organics Benzo(a)anthracene Benzo(b &/ or k)fluoranthene Benzo-a-pyrene Dibenzo(a,h)anthracene Indeno(l,2,3-cd)pyrene Other Organics PCB-1254 PCB-1260 2,3,7,8-TCDD (Dioxin) PLYMOUTH NORTH CAROLINA Atmospheric Degradation Potential Low Low Low Low Low Low Low Low High High High High High Low/ Madera te Low/Moderate Moderate Aquatic Degradation Potential Low Low Low Low Low Low Low Low Low/ Moderate Low/Moderate Low/ Moderate Low /Moderate Low/ Moderate Low Low Low/ Moderate Terrestrial Degradation Potential Low Low Low Low Low Low ·Low Low Low/ Moderate Low /Moderate Low/ Moderate Low/ Madera te Low/ Moderate Low Low Low /Moderate TABLE 5-2 (cont.)

Data are thus more likely to be accurate and can be interpreted with a high degree of confidence. In order to collect and record data in a uniform manner, controlling documents that described and specified quality assurance/ quality control (QA/QC) procedures for the field investigation were prepared and/ or used. The documents used.to guide and direct procedures throughout the investigation included: Environmental Investigations Standard Operating Procedures and Quality Assurance Manual, U.S. EPA Region JV, Science and Ecosystem Support Division, May 1996 and 1997 revisions U.S. EPA Region 4 Remedial Investigation Work Plan Georgia-Pacific Hardwood Sawmill Plymouth. North Carolina, Science and Ecosystem Support Division, August 1998 Final Work Plan for Remedial Investigation Georgia-Pacific Hardwood Sawmill Site Plymouth, North Carolina, CDM Federal Programs Corporation, January, 1999 Guidance for the Data Quality Objectives process, EPA 600/R-96/055, September 1994 The U.S. EPA Work Plan specified and described all QA, QC, analytical, data management, auditing and reporting procedures for this investigation. In addition, the U.S. EPA Work Plan established the DQO levels for field and analytical data using the DQO levels defined in EPA 600 / R-96 / 055 September 1994. For this investigation, field measurements such as pH, temperature, NTUs, conductivity, water level, and ground survey measurements were considered DQO screening data. The contaminant analysis data of surface water, sediment, soil, and groundwater provided by Contract Laboratory Program (CLP) laboratories and validated by Environmental Protection Agency (EPA) Science and Ecosystem Support Division (SESD) were considered definitive data. By providing a framework for sample collection, decontamination, field quality control, sample identification, chain-of-custody and sample handling procedures, the controlling documents help ensure that high quality data is collected and data comparability is enhanced. SPIN82/SEC1.WPD 6-1 I I I I I I I I I I I I I I I I I I I CDM 6.2 Field Investigation 6.2.1 Groundwater Sampling Section 6 Quality Assurance Report The work plan had called for the installation of ten temporary monitoring wells and then collection of groundwater from the temporary well points and from five existing monitor wells. Temporary monitoring well installation and sampling was performed in accordance with the specifications in the Work Plan except that only five temporary monitor wells were completed due to conditions encountered at the site. Additionally, nine of the permanent wells were sampled. As specified in the Work Plan, the samples were collected with a peristaltic pump. All groundwater samples collected were sent to CLP laboratories and analyzed according to DQO definitive data requirements. 6.2.1.1 Water Level Measurements Water level measurements followed the procedures specified in the work plan. Field measurements associated with this activity were conducted in accordance with DQO screening data requirements. 6.2.1.2 Field Parameter Measurements Field parameters (pH, specific conductivity, temperature, and turbidity) were measured on groundwater during well purging. Daily calibration of the monitoring instruments was performed and recorded in the field logbooks. In addition, post calibration checks were performed on the instruments following the days' activities. Instrument calibration and measurements performed appeared accurate and acceptable and no instrument malfunctions were reported. 6.2.2 Surface Water/Sediment Sampling Surface water and sediment samples were collected according to procedures specified in the work plan. However, instead of the six surface water and six sediment samples planned, three surface waters and seven sediment~ samples were collected. Surface water was not available at all locations to collect samples. All samples were sent to CLP laboratories and analyzed according to DQO definitive data. 6.2.5 Soil Sampling US EPA divided the site into 54 grids and collected one five-aliquot composite surface sample from each grid. Samples were analyzed for volatile organic compounds (VOCs), sernivolatile organic compounds(SVOCs), pesticides, polychlorinated biphenyls (PCBs), metals, and dioxin/ dibenzofuran (approximately 80% of the samples were analyzed for dioxin/ dibenzofuran). In addition, grab subsurface samples were collected at the center of each grid at a depth of 18" -24" bgs, and from grids 25 through 54 at a depth of 36" to 54" bgs. The grab samples were analyzed for VOCs, SVOCs, pesticides, PCBs, metals, and dioxin/ dibenzofuran (approximately 80% of the samples were analyzed for dioxin/ dibenzofuran). Two additional soil samples were collected onsite that were not associated with the 54 intially established grids. One sample was collected in an area just west of Grid 17, designated as sample GP055SLA. Another sample consisted of ash collected near the boiler house, and was designated as sample GP056SLA. These deviations occurred due to conditions SPINB2/SEC 1.WPD 6-2 I I I I I I I I I I I I I I I I I I I CDM Section 6 Quality Assurance Report encountered at the site. For example, some of the five point aliquots could not be collected due to buried obstructions. Twenty offsite locations were proposed for surface soil sample collection. However, only 14 locations were identified and samples were collected for volatiles and extractable organics, metals, pesticides,_ PCBs, dioxins, and furans. 6.3 Field Quality Control Procedures All data was collected as specified in the work plan. Field measurements were performed in accordance with procedures specified in the work plan. All monitoring instruments were calibrated either before each use, at the beginning of each field day, or at the frequency specified for each instrument. All sampling equipment that came in contact with sample media was decontaminated as specified in the work plan before each sample was collected. All sample collection, chain-of-custody, and sample shipping procedures were carried out as specified in the work plan. As part of the sample collection and analysis effort, field quality control samples were prepared to monitor the performance of the CLP laboratories and the offsite laboratories, and to check the field sampling procedures. A description of each QC sample type and QC sample results are discussed in Section 6.5. 6.4 Data Validation 6.4.1 CLP Laboratory Analysis All DQO Level IV data collected under the Georgia-Pacific remedial investigation were validated by EPA Region IV SESD using EPA CLP data validation procedures. The validation process involves review for compliance with holding times, instrument calibration, method and laboratory blanks, instrument tuning and performance data, and constituent quantification. Results of duplicate, matrix spike and other QC samples are used to assess precision and accuracy of the analytical data and potential matrix effects. The following qualifier flags are typically used by SESD to qualify data. A-Average Value NA-Not Analyzed NAI-Interferences ]-Estimated Value N-Presumptive Evidence of Presence of Material K-Actual Value Is Known To Be Less Than Value Given L-Actual Value Is Known To Be Greater Than Value Given U-Material Was Analyzed For, But Not Detected, The Number Is The Minimum Quantitation Limit R-QC Indicates That Data Is Unusable, Compound May or May Not Be Present; Resampling and Reanalysis is Necessary For Verification The purpose of validating the data is to allow the data user to interpret and use the data with varying degrees of confidence depending on how the data are qualified (e.g. unqualified, estimated, or rejected). SP1NB2/SEC1.WPD 6-3 I I I I I I I I I I I I I I I I I I I CDM Section 6 Quality Assurance Report For this investigation the data validation for both organic and inorganic analyses revealed that the overall data package can be accepted with confidence. However some data had to be rejected. Some results were rejected due to detection of analytes or compounds in blanks or insufficient recovery of spiked samples. For organics, in each media sampled, the "U" qualifier was applied on most data due to the contaminant being analyzed for but not detected at the minimum quantitation limit. The "J" qualifier was generally applied due to the sample containing those compounds less than the quantitation limits. Some extractable PAHs in samples were flagged with "J" due to low performance evaluation sample recovery for those PAHs. For the inorganics, the soils and sediment samples analyses resulted in actual levels of metals in most samples so no qualifiers were applied. For the aqueous samples analyzed much of the data was qualified "U" due to the those metals not detected at the minimum quantitation limit. For nonaqueous samples, the "U" was applied when the percent relative standard deviation %RSD greater than 20% for Inductively Coupled Plasma Emission Spectoscopy (ICP) multiple exposures and reported results were greater than instrument detection limit (IDL), but less than contract required detection limit (CRDL) or there was some baseline instability. The "J" qualifier was applied to some of the metals analyzed for a multitude of reasons which include matrix spike recovery and matrix duplicate out of control limits, and the Contract Laboratory Program Statement of Work (CLP SOW) requires analysis of two times CRDL standard for ICP analysis. 6.5 Data Evaluation As part of the overall data review, the results of field QC samples were examined so that effects of field procedures on data quality could be evaluated' Field QC samples included EPA blanks and spikes, duplicate samples, trip blanks, equipment rinsates, material blanks, and water blanks. In addition, sampling personnel collected sufficient volume for the CLP laboratories to analyze matrix spike and matrix spike duplicate samples. 6.5.1 EPA Spikes Spike sample ampules were shipped from SESD to the CLP laboratories. The laboratory provided full CLP documentation for spike sample analyses. Spike samples were submitted for liquid environmental matrices during the subject week of sample collection. The spike samples submitted to the CLP laboratories were analyzed for T AL and TCL parameters. The sample results were used by EPA to check adherence to procedures by the CLP laboratories. These samples were submitted to the respective CLP laboratories on a blind basis. Fictitious station numbers were used on the traffic report forms; the CLP laboratories did not know which samples were blanks and spikes. These samples were identified as such only on the copy of the traffic report forms that were returned to SESD and Sample Management Office (SMO). SPINB21SEC1.WPD 6-4 I I I u I I I I I I I I I I I I I I I CDM 6.5.1 EPA Inorganic Blank Section 6 Quality Assurance Report In addition to the EPA Spike, SESD also prepared a blind inorganic blank which is sent to the field personnel to be shipped along with the field collected samples to the CLP inorganic laboratories. It is given a ficticious sample location and is reported by the CLP with the field sample data. SESD evaluated the CLP analytical results and did not report any false positives. 6.5.2 Trip Blanks Trip blanks (for VOCs only) accompanied the shipments of samples to the CLP laboratory whenever coolers contained samples for VOA analyses. Trip blanks were prepared for both aqueous and soil/ sediment type samples. Trip blanks are used to show contamination potentially having occurred during sample handling or storage. The trip blank was prepared by the field team prior to the sampling event and kept with the investigative samples throughout the sampling event. It was then packaged for shipment with the other samples and sent for analysis. Trip blank results are presented in the Appendix A Quality Assurance Data. Only a few detections were noted in the trip blanks analytical results. All detections were qualified "U" or as a low "J" value. These detected constituents were generally common laboratory contaminants or metal salts are not considered site contaminants of concern. 6.5.3 Equipment Rinsates Rinsate blanks were obtained by running organic-free water over sampling equipment after it had been decontaminated. These samples were used to determine if cleaning procedures were adequate. Equipment rinsate samples were collected from decontaminated soil/ sediment sampling, groundwater sampling, and surface water sampling equipment. Rinsate blank results are presented in the Appendix A Quality Assurance Data. No constituents of organic or inorganic nature were detected in the equipment rinsates which would indicate inadequate decontamination of sampling equipment. 6.5.4 Field Blanks (Water Blanks) Field blanks are generally collected of the organic free water purification system which is connected to an onsite public water or well water supply. Water samples were sent for analysis of metals, volatile and extractable organics, pesticides and PCBs. No constituents of any significance were detected. 6.5.5 Duplicate Samples Field duplicates were collected as a means of quality control from the point of sample collection through all analytical processes. Duplicates were collected for all media sampled except sediment. The Relative Percent Difference (RPO) values calculated for field samples and their duplicates are calculated on positive results only. The RPO values calculated for inorganic analyses of the groundwater, surface water, sediment, and soil, sample/ duplicate pairs were: 15.3%, 2.3%, 10%, and 26%, respectively. This indicates that sample/ duplicate pairs for those media showed similar results and that the objectives of analyzing duplicate samples were achieved. The organic analytical results showed all non-detects for the sample/ duplicate pairs SPINB2/SEC1 .WPD 6-5 I I I I I I I I I I I I I I I I I I CDM Section 6 Quality Assurance Report except for dioxins and furans in the sediments and soil which had RPDs of 34% and 22% respectively. A soil extractable organic analysis RPD was calculated as 26% and was based on detections in three sample/ duplicate pairs. 6.6 Precision, Accuracy, Representativeness, Comparability, Completeness 6.6.1 Precision Precision is the evaluation of the reproducibility of a measurement. Precision is estimated by the analysis of duplicate samples and the calculation of RPD or RSD. This project involved both the collection of field duplicates and the creation of laboratory duplicates. Field duplicate samples serve as an indicator of overall precision from sample collection through laboratory analysis. Laboratory duplicates focus on precision of the analytical method. Based on the %RPD results on the duplicate analyses provided above and the goals for soil duplicates of 20% and for aqueous duplicates of 35%, the data has met the criteria. 6.6.2 Accuracy Accuracy is a measure of the bias in a system. It is the degree of agreement of a measurement with an accepted reference or true value. Accuracy for this project was estimated from the analysis of QC samples whose true values are known (surrogate or matrix spikes) and was expressed as percent recovery. EPA provided performance evaluation samples to the CLP laboratories including spike samples. These were analyzed by the CLP along with the site samples and reported. EPA SESD evaluated and validated the data according to the results reported by the CLP. The reported analytical qualitative and quantitative results of the spike samples were within acceptable limits for accuracy in CLP contract. 6.6.3 Representativeness, Comparability Repre_sentativeness expresses the degree to which data accurately and precisely represent a characteristic of a population at a sampling point, process condition or environmental condition. Comparability expresses the confidence with which one data set can be compared to another. Representativeness and comparability are qualitative objectives which were met by following standard operating procedures for sample collection and analysis. 6.6.4 Completeness Completeness is the measure of the amount of valid data obtained from a measurement system compared to the amount that was expected to be obtained under current normal conditions. SPINB21SEC1.WPD 6-6 I I I I I I I I I I I I I I I I I CDM Section 6 Quality Assurance Report The completeness of the data set for this investigation is based on the number of valid data points. Data validation and evaluation effects completeness of the data. Some data was rejected. Tables 6-1, 6-2, and 6-3 present the completeness data.

However, the remaining media and data set completeness was better than 96% which is generally acceptable for this type of sampling and analysis. 6.7 Audits 6.7 Audit Findings As part of COM Federal' s Quality Assurance Program, various projects are selected quarterly for auditing. Auditing can be either system or performance audits. Performance audits are quantitative checks on different segments of project activity; they are most appropriate for field measurements and for laboratory analysis activities. System audits are qualitive reviews of project activity to check that the overall COM Federal QA program is functioning and any project-specific QA and QC requirements are being met. System audits are generally performed on a selected number of projects per calendar quarter. This project was not selected for audit of the field activities by COM Federal Quality Assurance management since EPA performed the field work. However, an office audit of files was performed during March 2001. The audit revealed that the files were complete and organized appropriately.

In 1998, EPA initiated the RJ/FS to address all contamination at the site. The primary objective of the RI was to provide the additional data needed to support a baseline risk assessment and provide a basis on which to recommend a subsequent remedial action for the site. The RI was divided into five parts: • • • • • A soil sampling investigation (Section 2) A surface water/ sediment sampling investigation (Section 3) A groundwater sampling investigation (Section 4) A contaminant transport and fate evaluation (Section 5) A baseline risk assessment (submitted separately) The details of each of these investigations are presented in their appropriate sections and should be consulted for a full understanding of the results of the RI. The major conclusions reached as a result of the RI include the following: • Analyses of soil samples collected indicate extensive contamination by dioxins/ furans, PAHs, PCBs, and inorganics. This contamination seemed to be focused in an area centrally located on the site property where most past operations were located. However, following the removal action, selected contaminated grids and other waste materials located onsite were removed from the site. There was some indication of offsite contamination from site related constituents, however the concentrations were lower than onsite concentration. The results of the baseline risk assessment indicate that while the current human health risks associated with the levels of contamination found in the soils at the site are within EP A's acceptable target range, the potential future human health risks are slightly above EP A's acceptable target range, primarily due to the presence of dioxins/ furans, carcinogenic P AHs, and arsenic. • Surface waters at the site discharge into the Roanoke River. Analyses of surface water and sediment samples coltected from the intermittent drainage ditches located onsite indicate significant contamination by arsenic and manganese in surface water, and by dioxins/ furans, acetone, methyl ethyl ketone, PAHs, arsenic, lead, and zinc in sediments. The arsenic in sediment does exceed EPA' s Region 9 residential risk based guidance. The guidance is used as a screening tool for cleanup. This was taken into consideration for the baseline risk assessment for the site. The vertical extent of the sediment contaminants was not completed during this sampling period. The intent was to evaluate the sediment for direct contact exposure to human or ecological receptors. 7-1 I I I I I I I I I I I I I I I I I I CDM I SP!N2B/SECTT Section 7 RI Summary and Conclusions The results of the baseline human health risk assessment indicate that both the current and potential future human health risks associated with the levels of contamination found in the intermittent drainage ditches are within EP A's acceptable target range. • The site is underlain by a surficial unconfined aquifer. Groundwater flow at the site is likely toward the Roanoke River, where it discharges. Data on subsurface lithology was not gathered as part of this RI except during installation of the temporary well points. Analyses of groundwater samples at the site indicate significant contamination by arsenic and manganese. The results of the baseline risk assessment indicate that the potential future human health risks associated with the levels of contamination found in the groundwater are significantly above EPA's acceptable target range, primarily due to the presence of arsenic. In addition, the concentrations of some of the contaminants found are above SMCLs. Based on the results of the RI, the following actions are recommended: • • Remedial action objectives for soil and groundwater contamination at the site should be established based on human health exposure risks, as well as the potential for future contaminant migration from one medium to another (e.g., soils to groundwater). Alternatives for reducing soil and groundwater contamination at the site to achieve the established remedial action objectives should be evaluated, and the most cost-effective alternative for each implemented. 7-2 I I I I I I I I I I I I I I I I I I I CDM Section 8 REFERENCES BBL Environmental Services, 1999.

Based on the results of the RI, the following actions are recommended: • The former Georgia Pacific property (the Site) is not on the National Priorities List (NPL). Therefore, EPA cannot provide any funding to address the residual contamination identified in this RI report. However, EPA-Region 4 and the NCDENR agree there are several actions the current property owner could pay for (in lieu of a Fund- lead Remedial Action) to provide adequate protection of human health and the environment. These actions include capping several locations in the ditch with clean sand to minimize exposure to potential human or ecological receptors, and using institutional controls such as a Restrictive Covenant to eliminate the future use of contaminated groundwater. 7-2
