(Black & Veatch) on October 18, 2006, by the United States Environmental Protection Agency (EPA) Region 4. This SOW was issued through EPA Response Action Contract (RAC) No. 68-W-99-043 under Work Assignment (WA) No. 693- RICO-A44F (EPA, 2006a). This FSP was prepared by Black & Veatch for the documentation and explanation of all Rl/FS field activities, laboratory activities, and contract deliverables related to the acquisition and reporting of data for the Rl/FS. In addition, the FSP allows the EPA to review and approve plans prior to commencement of work. The following is a discussion of the Site's physical description and operational and regulatory history. The site background information provided in this section is taken from the following documents and their references. I) Work Assignment Form for Work Assignment No. 693-RICO-A44F (EPA, 2006a). 2) Expanded Site Inspection, Sigmon's Septic Tank Service, March 31, 2000 (NCDENR, 2000a). 3) Combined Preliminary Assessment/Site Inspection, September 30, 1998 (NCDENR, 1998). 4) Record of Decision, Summary of Remedial Alternative Selection, September 2006 (EPA, 2006b). 1.1 Location and Description of the Sigmon's Septic Tank Site The Site is located at 1268 Eufola Road approximately 5 miles southwest of Statesville, Iredell County, North Carolina (NCDENR, 2000a). The Site is located between Eufola Road to the north and Lauren Drive to the south. Private landowners own the properties located east and westofthe Site; the Pine Grove Cemetery is also located east of the Site (NCDENR, 2000a; USGS, 1993). A landing strip is located about 0.5 mile south of the Site (USGS, Field Sampling Plan EPA Contract No. 68-W-99-043 · Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 2 of 26 1993). The site vicinity map is shown on Figure 1-1, and the site layout map is shown on Figure 1-2 . The Site is approximately 15.35 acres in size (Moore, 1996a). According to Iredell County plat maps, the Site was divided into two properties at the time of its operation; the southern parcel is 8.9 acres in size and was listed in the name of the deceased Mr. Henry Sigmon, and the northern parcel is 6.45 acres in size and was owned by his daughter, Ms. Mary Sigmon (Iredell, 200 I). Mary Sigmon and her family lived in the onsite residence on the northern property. Several years ago, the Sigmon' s property was sold; the current owner owns both parcels and resides in the onsite house formerly occupied by Ms. Sigmon. For the purposes of this QAPP, the property will continue to be referred to as the "Sigmon Property" (EPA, 2006b). A 1.25-acre pond (former borrow pit) is located south of the Sigmon house (Black & Veatch, 200\a). An office trailer is located south of the pond, and an open-walled, roofed storage shed is located southeast of the office. Access to the interior of the property (i.e., to the office and open-walled shed) is provided by a gravel driveway that runs north-south along the eastern site boundary (EPA, 2006b). At the time of the site visit (September 26, 2001) there were empty, rusted drums; buckets; old tires; old car seats; and other debris within and near the storage shed; these have been removed since that time (Black & Veatch, 200 I a; EPA, 2006b) . According to Mary Sigmon, these materials are all from her father's operations. The drums formerly contained ·car wash fluids and/or liquid waste from International Paper (Black & Veatch, 200 I a). Approximately I 00 feet south of the shed next to the gravel drive are six aboveground storage tanks (ASTs) containing liquid wastes. The ASTs include: 2 rectangular concrete basins (approximately 1,000 gallons each), 2 cylindrical rusted tanks (approximately I 0,000 gallons each), and 2 cylindrical rusted tanks (approximately I 2,000 gallons each). According to Mary Sigmon, the waste contained in the ASTs predates Sigmon Environmental operations and the source of the waste is unknown (Black & Veatch, 2001a).

Two lightly -vegetated open pits approximately 2 to 3 feet in depth are located near the southeastern comer of the Site. The two pits are approximately 30 feet by 10 feet and 15 feet by 8 feet in size. The Site is fenced with a 4-foot barbed wire fence, and warning signs are posted on the fence and trees. There are breaks in the fence on the eastern and southern sides of the site (Black & Veatch, 2001a). A site layout map is provided as Figure 1-2. 1.2 Site Operational History Sigmon Septic Tank Service, a wholly owned subsidiary of AAA Enterprises, was owned and operated by the Sigmon family since 1948. In 1970, the Henry Sigmon purchased the property at 1268 Eufola Road and moved operations to this location (Moore, 1996b). The business pumped septic tank wastes and heavy sludges from residential, commercial, and industrial customers; installed and repaired septic tanks; and provided a variety of industrial waste removal services. In 1980, a nephew of Henry Sigmon, Mr. Frank Sigmon, stated to North Carolina Department of Human Services that the septic service had pumped from Barnhardt, Clark Equipment, and Union Glass (Grayson, 1980). In 1996, Henry Sigmon mentioned to North Carolina Department of Environment and Natural Resources (NCDENR) that some of the septic wastes came from a medical supply company, Zimmer Industries, and a metal treating business, Ro-Mac Company, (Moore, 1996b). Other than those sources mentioned by Mary Sigmon, no other sources of septic waste have been named in the file material. From 1970 to 1978, the wastewaters were discharged to the City of Statesville sewer. Around 1973 or 1974, the service received permits and land applied sludges to area farmlands (Moore, 1996b). The process of land application appears to have continued until at least I 989, according to septage management applications filed by AAA Enterprises (NCDSWM, 1989a; NCDSWM, 1989b; NCDSWM, 1992). The file material does not specify on which properties the sludges were applied and whether the farmlands produced food crops. Around 1978 or 1979, the Sigmons dug several lagoons at the site and began placing septic wastes inside these lagoons (Moore, 1996b; Read ling, 1990). Henry Sigmon stated that he had received verbal permission from the Iredell County Health Department and the Mooresville Regional Office ofNCDENR to construct and use the lagoons for scptage disposal. No permits were issued for the lagoons (Moore, 1996b; Readling, 1990). AAA Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RIC0-A44F Sigmon 's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 4 of 26 Enterprises and Sigmon Septic Tank Service ceased doing business for financial reasons on September 28, I 995 (Homesley, 1996). Shortly thereafter, Mary Sigmon purchased two trucks from Sigmon Septic Tank Service and started Sigmon Environmental, the previous operator of septic waste services at the site (Moore, 1996b ). Sigmon Environmental was permitted to discharge to the Irwin Creek Wastewater Treatment Plant and the McAlpine Creek Wastewater Treatment Plant since late 1995 (NCDSWM, 1995; NCDSWM, 1997a; NCDSWM, 1997b). The number and size of the unlined lagoons which existed at the site is unclear after a thorough review of the file material. Eight to ten unlined lagoons were utilized to hold septic wastes. Some references indicate the lagoons were uniform in size while others depict lagoons differing widely in size (Connell, 1995; DeRosa, 1996; Grayson, 1980; Martin, 1992; Moore, 1996b; Readling, 1990; Sigmon, 1980; Sigmon, 1995). At times, some of the lagoons were connected with piping, referred to as a septic T, to drain water from other lagoons and facilitate the dewatering of the sludges (Readling, 1990). As of September 1990, eight unlined lagoons were active; six were used for septic waste and the remaining two for dewatering (Readling, 1990). According to the son, Mr. Barry Sigmon, no septage was added to the lagoons after the spring of 1992 (Martin, I 992). It is unknown if the lagoons ever discharged overland to the surface water pathway. Lotic (i.e., flowing) surface water features near the site consist exclusively of ephemeral drainage ditches that collect stormwater and are the discharge points for shallow groundwater flow at the Site. One unnamed drainage feature exists to the south of the Site, and another unnamed drainage feature carries drainage from Sigmon onsite toward the west. The nearest perennials streams or rivers are about one-half mile west and southwest of the Site (i.e., Reeder Creek and the Catawba River). Uncontrolled migration of overland storm water flow may impact several small lentic (i.e., pond) surface water features in the area: Davidson Pond to the south of the Site, Sigmon Pond within the Site boundaries, and Lambreth and Williams Ponds to the west of the Site (Figure 1-2). Further west of these, Slinwinski Pond lies within the drainage ditch system between the Site and the Cataba River, and it could receive storm water flow originating from the Site, as well (Figure 1-2) (EPA, 2006b ).

Nine temporary monitoring wells were installed in the vicinity of the lagoons in September 1980 by the North Carolina Department of Natural and Economic Resources. The samples were analyzed for alkalinity, bicarbonate, carbonate, chloride, dissolved solids, hardness, and pH (NCDEM, 1980). In November 1980, Sigmon Septic Tank Service submitted an interim status hazardous waste permit application (EPA Part A) indicating that the site was used for disposal of hazardous waste. The site was assigned EPA identification number NCD 062 555 792. Over the subsequent 17 months, Mary Sigmon rescinded their permit application as a generator and requested that the facility be reclassified as a transporter of hazardous wastes (Sigmon, 1980; Sigmon, 1981; Sigmon, 1982; Zeller, 1981 ). In either 1985 or 1986, two of the lagoons were apparently covered and closed out (NCDENR, 1998). In 1987, North Carolina Department of Natural Resources and Community Development installed and sampled four additional temporary wells (MW I through MW 4) along the western edge of the lagoons and south of the storage shed (NCDNRCD, 1987). Analytical results indicated elevated levels of nitrates, barium, chromium, copper, iron, mercury, manganese, and lead above EPA maximum contaminant levels (MCLs) or the Title 15A Subchapter 2L Classification and Water Quality Standards Applicable to the Groundwaters of North Carolina. A sample of wastewater from the lagoons was also collected at this time and contained elevated levels of arsenic, aluminum, copper, iron, mercury, magnesium, manganese, lead, and zinc (NCDENR, 1998; NCDENR, 2000). Since 1989, Sigmon's Septic Tank Service submitted applications and received permits from the North Carolina Septage Management Program to operate a Septage Management Firm and a Septage Disposal Site. The permit states that pumpings may only be discharged at specified wastewater treatment plants (NCDENR, 1998) . • Field Sampling Plan EPA Contract No, 68-W .99-043 Work Assignment No. 693·RICO•A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 6 of 26 1.3.2 North Carolina Department ol Environment and Natural Resources: 1990 In June 1990, the Division of Environmental Management (DEM) analyzed groundwater samples from monitoring wells MW3 and MW 4 and detected elevated levels of iron, lead, manganese, and mercury above North Carolina groundwater standards (Readling, 1990). On August 9, 1990, DEM notified Sigmon's Tank Septic Service of a notice of violation regarding the groundwater contaminant levels (DeRoller, 1991). Sigmon's was required to submit a site assessment report and to install two monitoring wells to replace wells MW I and MW2 which had been damaged (NCDENR, 1998). 1.3.3 North Carolina Superfund Section Investigations: 1990 In September 1990, the DEM referred the site to the North Carolina Hazardous Waste Section. A site investigation was conducted in 1990 by the North Carolina Hazardous Waste Section. It was observed that two of the lagoons had been closed out and that two other lagoons contained the water run-oft from the remaining six lagoons. That water was used for irrigation purposes (Readling, 1990). In March 1991, the Division of Solid Waste Management issued a notice of violation regarding groundwater contaminant levels in onsite monitoring wells and required the liquid waste and soil of the lagoons to be characterized in each of the lagoons (DeRoller, 1991 ). Additionally, beginning in 1991 DEM has collected groundwater samples from nearby private wells. Detectable or elevated concentrations of metals and organic contaminants have been detected in several of those samples (NCDENR, 2000). 1.3.4 North Carolina Department ol Environment and Natural Resources: 1992 On August 31, and September I, 1992, DEM and the North Carolina Hazardous Waste Section conducted a site investigation and sampling trip to determine whether the wastes in the lagoons were hazardous. Water samples were collected from the eight remaining lagoons and sludge samples were collected from five of the eight lagoons. Analytical results indicated the detectable or __ elevated concentrations of 7 metals and 13 volatile organic compounds (VOCs) in the aqueous samples and 4 metals and 18 VOCs in-the sludge samples. All concentrations were below Resource Conservation and Recovery Act (RCRA) Toxicity Characteristic Leaching Procedure (TCLP) levels; therefore, the site was transferred to the North Carolina Solid Waste Section for continued evaluation (NCDENR, 199"8).

The Sigmon's were issued another notice of violation and were ordered to supply an alternate source of drinking water for two residences located approximately 400 feet southwest of the lagoons (Moore, 1996a, NCDENR, 2000). 1.3.6 Site Owner Investigation: 1993 In September 1993, the Sigmon Septic Tank Service hired Shield Environmental Associates, Inc., to sample and characterize the sludges in the eight unlined lagoons to comply with a closure request by NCDENR Department of Environmental Management (Burrows, 1993). The results indicated elevated levels of total petroleum hydrocarbons, metals, and several organic compounds (Burrows, 1993; NCDENR, 2000). Seven of the eight lagoons were closed by April 1995 and the final lagoon, used to store surface water runoff during the closure process, was closed in May 1995 (Sigmon, 1995). Reportedly, the lagoon sludges were excavated to a depth of IO feet, mixed with sawdust, and stockpiled in one of the lagoons (Connell,· 1995). However, a neighbor who assisted in the closure, Mr. Danny Lambreth, claims that sawdust was not added to the sludge (Black & Veatch, 2001b). The lagoons were backfilled with soil excavated from the northern portion of the site. In late 1996, NCDENR visually estimated the quantity of sludge in the waste pile as 2,000 to 2,700 tons and the areal dimensions of the former lagoon area as approximately 215 feet by 250 feet, or 1.21 acres (Moore, 1996b ). 1.3.7 North Carolina Superfund Section Investigation: 1995 In December 1995, the site was referred to the North Carolina Superfund Section by DEM regarding a possible emergency removal action determination for the waste pile (Connell 1995). Land application of the sludge was considered but denied due to lack of sufficient acreage to apply the sludge (NCDENR, 1998).

In January 1997, the North Carolina Superfund Section referred the site to the EPA Region 4 Emergency Response and Removal Branch for a removal evaluation. In April 1997, EPA responded that the site did not meet the criteria for an emergency removal action (Lair, 1997). 1.3.9 North Carolina Superfund Section Investigation: 1998 In 1998, the North Carolina Superfund Section conducted a combined Preliminary Assessment/Site Inspection (PA/Sl) for the site. The PA/SI included the collection of nine groundwater samples, 15 soil samples (including one duplicate), eight surface water samples (including one duplicate), and nine sediment samples (including one duplicate). The samples were analyzed for inorganics, volatile organics, extractable organics, and polychlorinated biphenyls (PCBs). The PA/SI confirmed the presence of groundwater contamination south and east of the site; constituents detected in the wells included barium, chromium, lead, manganese, mercury, chlorobenzene, 1,4-dichlorobenzene, and 1,2-dichlorobenzene. The investigation also confirmed the presence of organic and inorganic contaminants in the soils associated with the lagoons and waste pile. The surface water pathway was also a concern. Samples from two of the primary points of entry that were documented as fisheries contained barium, chromium, lead, manganese (Davidson pond), and magnesium (an unnamed tributary). PCBs were not detected above the sample quantitation limit in any of the PA/SI samples (NCDENR, 2000). 1.3.10 North Carolina Superfund Section Investigations: 2000 An Expanded Site Inspection (ESl) was completed by the North Carolina Superfund Section in March 2000 (NCDENR, 2000). The ESI included the collection of nine groundwater samples (including one duplicate), ten soil samples (including one duplicate), six surface water samples, and six sediment samples. The samples were analyzed for inorganics, volatile organics, and extractable organics. One groundwater sample was collected from an onsite monitoring well. The remaining groundwater samples (including one duplicate) were collected from private wells, including one private well that served as a background well.

Two soil samples were collected from the waste pile at a depth of approximately one foot into the pile. Two soil samples were collected as background surface and subsurface soil samples. The remaining two soil samples were collected from the drainage ditch on both sides of the culvert leading to the Davidson pond to determine attribution of contamination found in the pond. Two surface water and sediment samples were collected from the Davidson pond, one from the PPE into the pond and one from just upgradient of the discharge culvert from the pond to the downgradient surface water pathway. One surface water and sediment sample was collected at the PPE into the perennial stream located southwest of the site. Two surface water and 1 sediment samples were collected upstream of that PPE as attribution samples. One surface water and sediment sample was collected from the West's pond to serve as a background sample. Several constituents were detected in groundwater samples at concentrations either two times greater than background levels or exceeding sample quantitation limits (SQ Ls), including: aluminum (8800 micrograms per liter (µg/L)), arsenic (4.2J µg/L), barium (83 to 620 µg/L), chromium (86 µg/L), cobalt (1.2 to 39 µg/L), iron (11000 µg/L)(manganese (15 to 27000 µg/L), mercury (l.lJ to 6.61 µg/L), nickel (2.3 to 73 µg/L), 1,1-dicholoroethane (3 µg/L), 1,2-dichlorobenzene (8 µg/L), 1,3-dichlorobenzene (I µg/L), 1,4-dichlorobenzene (2 to 11 µg/L), acetone (SJ to 291 µg/L), benzene (2 µg/L), chlorobenzene (72 µg/L), chloroethane (I µg/L), cis-1,2-dichloroethene (3 µg/L), and total xylenes (2 µg/L). Analytical results are summarized in Table 1-1 located in Appendix A. The soil samples collected from the waste pile were compared to the surface soil background sample; the soil samples from the lagoon were compared to the subsurface soil background sample. The following constituents were detected in the waste pile samples at concentrations either two times greater than the surface soil background concentration or exceeding the SQ Ls: aluminum (31000 milligrams per kilogram [mg/kg)), antimony ( 421 mg/kg), arsenic (3.2 to 3.8 mg/kg), barium (230 to 310 mg/kg), cadmium (3.9J to 4.61 mg/kg), chromium (60 to 75 mg/kg), copper (2001 to 3801 mg/kg), iron (17000 to 23000 mg/kg), lead ( 1801 mg/kg), manganese (I 80 to 290 mg/kg), mercury (0.26 to 0.56 mg/kg), nickel (6 I to 74 mg/kg), silver (3.5 mg/kg), vanadium ( 41 to 49 mg/kg), zinc (870 to 880 mg/kg), 3-and/or 4-methylphenol (72001 micrograms per kilogram [µg/kg)), I, I-bi phenyl (17001 µg/kg), 4-chloroaniline Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 10 of26 (34001 to 14001 µg/kg), 1,2-dichlorobenzene (250 µg/kg), 1,3-dichlorobenzene ( 19 µg/kg), · 1,4-dichlorobenzene (24 to 120 µglkg), 2-methylnaphthalene ( I 9001 to 36001 µg/kg), acetone (21 µg/kg), benzyl butyl phthalate (220000 µg/kg), bis(2-ethylhexyl)phthalate (38000 to 240000 µg/kg), chlorobenzene ( l lJ µg/kg), ethyl benzene ( 41 µg/kg), methyl butyl ketone (270 µg/kg), methylcyclohexane ( 40 µg/kg), naphthalene (25001 to 3 7001 µg/kg), phenanthrene (18001 µg/kg), toluene (63 µg/kg), and total xylenes (200 µg/kg).

Analytical results are summarized in Table 1-2 located in Appendix !-,.. The soil samples collected in the drainage ditch were compared to the background surface soil sample. The following constituents were detected at elevated concentrations when compared to the background surface soil sample: aluminum (30000 mg/kg), arsenic (2. 7 to 3.4 mg/kg), barium (85 to 160 mg/kg), chromium (21 to 31 mg/kg), cobalt (7.8J mg/kg), copper (!OJ to 24 J mg/kg), iron (19000 to 20000 mg/kg), lead (12J to 13J mg/kg), manganese (1300 to 4200 mg/kg), nickel (8.2 to 17 mg/kg), vanadium ( 45 to 46 mg/kg), zinc (36 to 100 mg/kg), benzenaldehyde (4401 µg/kg), benzo(a)anthracene (830 µg/kg), benzo(a)pyrene (730 µg/kg), benzo(b)tluoranthene (960 µg/kg), benzo(k)tluoranthene (840 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 11 of26 µg/kg), chrysene (920 µg/kg), dimethyl phthalate (460 µg/kg), fluoranthene (1600 µg/kg), phenanthrene (1200 µg/kg), and pyrene (1600 µg/kg). Analytical results are summarized in Table 1-2 located in Appendix A. Surface water sample SST-023-SW was considered a background sample during the ESI; however, it was collected from a surface water pathway that could potentially be impacted by the site. The following constituents were detected in surface water samples at elevated concentrations when compared to background sample SST-021-SW: aluminum ( 1900 micrograms per kilogram (µg/L]), arsenic (3.6J to 18J µg/L), barium (14 to 210 µg/L), cadmium (I to 1.2 µg/L), cobalt (4.8 to 14 µg/L), iron (740 to 7000 µg/L), lead (I .3 to 4.1 µg/L), manganese (35 to 1300 µg/L), nickel (4.3 to 11 µg/L), and zinc (85 to 220 µg/L). The highest concentrations of these constituents were typically found in the samples collected from the Davidson pond. Analytical results are summarized in Table 1-3 located in Appendix A. Sediment sample SST-023-SD was considered a background sample during the ESI; however, it was collected from a surface water pathway that could potentially be impacted by the site. The following constituents were detected in sediment samples at elevated concentrations when compared to background sample SST-021-SD: arsenic (8 mg/kg), barium (210 mg/kg), chromium (46 mg/kg), copper (37J mg/kg), iron (3200 to 37000 mg/kg), manganese (280 to 380 mg/kg), nickel (21 mg/kg), and zinc ( 150 mg/kg). Analytical results are summarized in Table 1-4 located in Appendix A. The two soil samples collected from the drainage ditch upgradient of the Davidson pond have also been included on Table 1-4 located in Appendix A. Although not detected above the SQ Ls of the background sediment sample, numerous polynuclear aromatic hydrocarbons (PAHs) were detected in the Davidson pond. Many of these constituents were also detected in the soil sample SST-018-SL collected in the drainage ditch between the road and the pond, indicating that contamination in the pond may be attributable to a source other than the site. 1.3.11 EPA's Superfund Remedial Site Evaluation Branch: 2002 In May 2002, the EPA conducted a geophysical investigation at the Site. The objective was to obtain information on the location of the former lagoons and pits which would guide Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 12 of26 future soils sampling and support of the RI/FS for the Site. The results of that investigation, documented in the Geophysical Investigation Report for Sigmon 's Septic Tank Site, Statesville, North Carolina, indicated the presence of both non-ferrous and ferrous metallic, non-native metals in the subsurface soil at the Site. Those results were used to guide future soil sampling investigations (EPA, 2006b ). In October 2004, a data evaluation report (DER) was completed by the EPA. The DER evaluated the usability of data collected by the RI project team to support project conclusions and recommendations for the Site RI/FS. The DER summarized and evaluated data collected from the October 2002, March and April 2003, and May 2004 sampling events. An additional field investigation was conducted in February 2005 to primarily address the delineation of soil contamination at the Site. A DER was not written for the February 2005 soil data; however, the Operable Unit (OU) I RI report reviews, evaluates, and discusses this new data set in detail. Therefore, a separate DER was not necessary. The October 2002, March and April 2003, May 2004, and February 2005 sampling investigations and data sets collected during the RI are presented in Tables 1-5 through 1-17 located in Appendix A. 1.3.12 EPA's Emergency Response and Removal Branch: 2006 In November 2005 the site was referred to EPA' s Emergency Response and Removal Branch (ERRB) regarding a possible time-critical removal action for the residential wells. Several potable wells in the vicinity of the Site were contaminated with inorganic and organic contaminants. More information on the sampling is provided in Section 1.3 .11. The ERRB installed filters on these wells in April 2006. 1.3.13 Remedial Investigation: 2006 The contaminant source areas at the Site consist of soil and debris associated with 8 to I 0 unlined lagoon pits created by the Site owners in 1978 or 1979. The OU I (soil) RI for the Site successfully delineated the nature and extent of contamination in all media, except groundwater. The groundwater will be further investigated in the Sigmon's Septic Tank (Sequence 2) Site RI. The nature and extent of contamination at the Site is based on a detailed discussion of analytical results associated with environmental media samples collected during RI fieldwork conducted between October 2002 and February 2005 (Black & Veatch, 2006a; EPA, 2006b ).

In 2002, a total of 12 surface soil samples including one duplicate and 20 subsurface soil samples/borings including one duplicate and 17 subsurface soil samples/borings including one duplicate were collected during the field investigation. Additional soil sampling was proposed for 2005 to determine the nature and extent (both vertical and aerial) of soil and subsurface soil contamination above screening standards in order to support selection and implementation of a cleanup remedy. Therefore, a 2,500-feet by 1,000-feet grid with 125 locations covering onsite and offsite areas was proposed in the FSP. In addition to duplicates and other QA/QC samples, the FSP proposed a total of 56 surface soil grid (depth interval O to 12 inches) samples to be collected from within the Site boundary. Tab le 1-14 located in Appendix A presents the locations and selection rationale for surface soil samples collected for laboratory analysis in 2005. A total of 69 surface soil (depth interval Oto 12 inches) sample locations were proposed for x-ray fluorescence (XRF) analysis. These 69 locations were selected from among 125 gird nodes within the Site boundary (i.e., within the dashed line on Figure 1-6, located in Appendix A). Collocated subsurface soil samples (I to 2 feet bis) were proposed for XRF analysis at locations where surface soil XRF results showed concentrations of an indicator metal (i.e., aluminum) to be above screening standards. The sampling grid was to be extended if XRF results showed additional delineation as necessary. Additional XRF data were collected from 17 subsurface soil sample locations at various intervals at each boring location. Confirmatory soi I samples were collected from 20 percent of the proposed XRF analysis locations outside of the Site boundary (i.e., outside of the dashed line shown on Figure 1-5. The confirmatory surface soil samples were submitted to the EPA Contract Laboratory Program (CLP) laboratory. An additional 56 surface soil sample locations from within the dashed line were proposed for XRF analysis; these are shown on Figure 1-6 located in Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO·A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 14 of26 Appendix A. Table 1-14 located in Appendix A presents the proposed 2005 soil sample locations and rationale. During the February 2005 field investigation, a total of 79 surface soil samples (including nine duplicates) and 40 subsurface soil samples/borings (including 5 duplicates) were collected and shipped for analysis. The Sampling and Analysis Plan (SAP) proposed a composite sample from 0 to 12 inches; however, during the investigation, a composite sample was collected from Oto 6 inches to represent a surface soil sample. It was concluded that a sample from Oto 6 inches would be more representative of site conditions and that this data would be better used in the Human Health Risk Assessment (HHRA). Soil sample SS- SF-01 BG and SS-SB-0IBG were designated as background samples because they were collected adjacent to SS-MW-1 OB, which was designated as the background monitoring well. A total of I 06 surface soil and 77 subsurface analytical soil samples were collected from the 2002, 2004, and 2005 field investigations. Figures I-7 and 1-8 located in Appendix A present 2002, 2004, and 2005 sample locations from which surface and subsurface soil samples, respectively, were collected for laboratory analysis. Surface and subsurface soil locations analyzed by XRF are included in Appendix A and shown on Figures 1-6 and 1-9, respectively. One hundred twenty-five surface soil (0 to 12 inches bis) samples were proposed for XRF analyses. During the February 2005 field investigation, the following nine samples were not collected because the property owner refused to allow access: SS-SF/SB-Al2, SS-SF/SB- Al4, SS-SF/SB-Al6, SS-SF/SB-Al 8, SS-SF/SB-A20, SS-SF/SB-A22, SS-SF/SB-B 15, SS- SF/SB-BI 7, and SS/SF/SB-Bl 9. An additional two sample locations (SS-SF/SB-B2 I and SS-SF/SB23) were analyzed using the XRF; however, these data were not retrievable from the XRF unit. XRF data were proposed to be obtained from a composite surface soil sample collected from a soil core taken from 0 to 12 inches. During the sampling event, field personnel modified the data collection procedure to allow surface soil sample XRF readings to be taken in-situ from both 0 inches and 6 inches. Due to extreme surface soil saturation caused by intense storm activity, field personnel had difficulty collecting and homogenizing surface soil at most locations. A composite surface soil sample was not prepared for XRF analysis because the ground was saturated. Furthermore, field personnel judged that the in- situ XRF data from 6 inches bis was more representative of typical surface soil conditions I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 15 of26 than the in-situ XRF data from the surface (i.e., 0 inches). Confirmatory sample selection from these XRF analysis locations was based on the 6-inch XRF sample analysis. During the February 2005 sampling event, a total of 226 surface soil (a combination of 0- inch and 6-inch in-situ XRF readings) and 146 subsurface soil samples were analyzed by XRF. Figures 1-6 and 1-9 located in Appendix A show the surface and subsurface soil locations, respectively, from which XRF data were obtained (EPA, 2006b ). Surface Water aud Sediment Sampling. In 2002, eight surface water samples (including one duplicate) were colkcted from locations collocated with sediment samples. In 2004, one surface water sample and four sediment samples were collected. These samples were collected to provide data for the ecological risk assessment, establish upgradient background concentrations, examine surface water to groundwater discharge, and determine the nature and extent of offsite contamination of these media. SS-SW-01 and SS-SD-01 were designated as background samples because they are upgradient and relatively distant from the site. Figure 1-10 located in Appendix A presents the 2002 and 2004 surface water and sediment sample locations (EPA, 2006b ). Existing Private Potable Well Sampling Location. Between 1991 and 1999, groundwater samples were collected from 11 nearby private wells (see Figure 1-11 located in Appendix A). Approximately 36 samples were collected and analyzed for nitrates, sulfates, metals, VOCs, and semivolatile organic compounds (SVOCs). Table 1-5 located in Appendix A summarizes the analytical results. Private wells PW2 and PW3 detected concentrations for six chemicals (i.e., nitrates, iron, manganese, mercury, 1,4-dichlorobenzene, and I ,2- dichloroethane) that exceeded the EPA's National Primary/Secondary Drinking Water Standards (MC Ls/secondary maximum contaminant levels [SMCLs]) (EPA, 2002b). In 2002, a total of nine groundwater samples, including one duplicate sample, were collected from potable wells during a field event. Private potable wells SS-PW-01, SS-PW-03, SS- PW-04, SS-PW-05, SS-PW-06, SS-PW-07, SS-PW-08, and SS-PW-09 were sampled. Due to its location, SS-PW-07 was designated as a background private potable well sample.

To determine if an emergency action was required, the well was re-sampled in March and April 2003 by Black & Veatch. In March 2003, the well as sampled at the well spigot per the technique used for the other RI potable well samples. In April 2003, the spigot was again sampled, and filtered and unfiltered samples of the kitchen tap were collected. All 2003 sample results were under the 15 mg/L MeL. In 2004, a total of nine groundwater samples, including one duplicate sample, were collected from potable wells during another field event. Private potable wells SS-PW-01, SS-PW-03, SS-PW-04, SS-PW-05, SS-PW-06, SS-PW-08, SS-PW-09, and SS-PW-10 were sampled. The concentrations detected in some of these drinking water wells exceeded MeLs. The analytical results are indicated in Table 1-5 located in Appendix A(EPA, 2006b ). RI Summary. Numerous samples of media from the suspected source area were analyzed for inorganics, dioxins/furan, SVOes, pesticides/PeBs, and voes. A number of these analytes were detected among various media samples; however, not all analyte detections exceeded corresponding screening values. The analytical data obtained from the sampling efforts suggest that the nature of contamination at the Site is relatively narrow in scope, limited primarily to metals with some localized svoes and voes contamination. This contamination is summarized in Appendix A on Table 1-15, which indicates the presence of detected concentrations by a single check-mark(✓) and the presence of concentrations exceeding screening values by a double check-mark ( ✓ ✓). Samples of media from the source area contain consistent and frequent detections and screening value exceedances of the following metals: aluminum, arsenic, barium, calcium, chromium, copper, iron, lead, magnesium, manganese, nickel, and zinc. Samples of surface soil and subsurface soil contain frequent detections and a few screening value exceedances of a number of SVOes ( e.g., naphthalene, various P AHs, bis-(2-ethylhexyl] phthalate, 1, l '- biphenyl) and several pesticides (e.g., alpha-chlordane, gamma-chlordane, heptachlor epoxide, alpha-BHe, beta-BHe, 4,4-dichlorodiphenylethylene [DDE], and 4,4'- dichlorodiphenyltrichloroethane [DDT)).

Surface soil contains very few voe detections and no screening value exceedances. The analytical data is summarized in Tables 1-6 through 1-11 located in Appendix A. Subsurface soil associated with the Site boundaries may be impacted by site-related contamination through infiltration of precipitation, percolation of contaminants associated with the downward migration of storm-water, and soil grading activities involving trenching and digging into the subsurface. Numerous samples of surface soil, subsurface soil, surface water, and sediment were analyzed for inorganics, dioxins/furans, SVOes, pesticides/PeBs, and voes. A number of these analytes were detected among the various media samples; however, not all analyte detections exceeded corresponding screening values. The analytical data obtained from these media sampling efforts suggests that the nature of contamination at the Site is relatively narrow in scope, limited primarily to metals with some isolated occurrences of a few organics. The analytical data is summarized in Tables 1-6 through 1-13 located in Appendix A. Samples of surface water and sediment contain consistent and frequent detections and screening value exceedances of the following metals: aluminum, arsenic, barium, calcium, chromium, copper, lead; magnesium, manganese, nickel and zinc. Surface water and sediment contain very few voe detections and no screening value exceedances. The analytical data is summarized in Tables 1-12 and 1-13 located in Appendix A (Black & Veatch, 2006a; EPA, 2006b ). 1.3.14 Baseline Risk Assessment: 2006 Based upon the results of the RI, a Baseline Risk Assessment (BRA) was conducted to estimate the risks associated with current and future site conditions. A BRA is an analysis of the potential adverse human health and ecological effects caused by hazardous substance releases from a site in the absence of any action to control or mitigate these under current and anticipated futtire land uses. Field Sampling Plan EPA Contract No. 68-W-99.043 Work Assignment No. 693-RIC0-A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 18 of26 Human Health Risk Assessment. A HHRA was developed using data obtained during field investigations conducted at the Site in 2002, 2003, 2004, and 2005. The data were summarized to show all organic and inorganic chemicals that were positively identified in a least one sample. Chemicals identified as tentatively identified (i.e., those qualified with the "N" flag) were not included in the HHRA (Black & Veatch, 2006b; EPA, 2006b ). The HHRA identified five metals as chemicals of concern (COCs) in surface and subsurface soil (aluminum, chromium, iron, thallium, and vanadium) when considering the following receptors and exposure routes: Media Surface Soil Receptor Adolescent Trespasser Worker (Outdoor) Construction Worker Residents Subsurface Soil Construction Worker Exposure Route Ingestion and Dermal Contact Ingestion and Dermal Contact Ingestion, Dermal Contact and Inhalation Ingestion and Dermal Contact Ingestion, Dermal Contact, and Inhalation COCs are identified as having an excess cancer risk level of I X I 04 or a hazard index (HI) of I. More specifically, COCs have either individual excess cancer risk levels equal to or greater than I X 10-0 or an hazard quotient (HQ) equal to or greater than 0.1 in a given exposure scenario. However, none of the COCs identified in this HHRA has toxicity data indicating its potential for carcinogenic health effects in humans via the oral, dermal, or inhalation routes. COCs are also values that exceed state or federal applicable or relevant and appropriate requirements ( ARARs ). Although aluminum was identified as a COC for both onsite and offsite surface soil, further evaluation of both the historical and RI field investigation data revealed that the maximum concentrations found in surface soil (72,000 mg/kg and 64,000 mg/kg) were less than the child resident HI of I and the risk-based remedial goal option (RGO) of 76,865 mg/kg; therefore, aluminum was eliminated as a HHRA COC for surface soil.

Therefore, chromium has been eliminated as a HHRA COC for surface and subsurface soils. Although iron was identified as a COC for both surface and subsurface soils, further evaluation of both the historical and RI field investigation data revealed that with the exception of one location, the maximum concentrations found in surface soil were less than the child resident HI of I and the risk-based RGO of 22,730 mg/kg, and the maximum concentrations found in' subsurface soil were less than the construction worker HI of I and the risk-based RGO of 91,729; therefore, iron was eliminated as a COC for both surface and subsurface soils. Thallium was originally identified as a COC for surface soil; however, maximum concentrations found in both surface soil and subsurface soil were less than the risk-based RGO of 6 mg/kg. Therefore, thallium was eliminated as a COC for surface soil and subsurface soil. Vanadium was also identified as a COC for surface soil in the HHRA. Concentrations of vanadium were found in both onsite and offsite surface soils above the child resident HI of I and the risk-based RGO of 73 mg/kg; therefore, vanadium has been retained as a direct contact COC for surface soil (Black & Veatch, 2006b; EPA, 2006b ). The Risk-Based RGOs and ARARS for Surface and Subsurface Soils are identified in Table 1-16 located in Appendix A. Soil-to-Groundwater Leachability Criteria This section addresses the soil screening standards based on soil-to-groundwater leaching for the groundwater COCs identified in the HHRA. The criteria evaluated and selected are presented in Table 1-17 located in Appendix A and are discussed below: Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 20 of 26 EPA Region 9 Preliminary Remediation Goals (PRGs) - A site-specific dilution attenuation factor (OAF =3) was determined in the OU I RI. The screening criteria based on the site-specific OAF was determined via linear interpolation between the criteria presented for OAF= 1 and OAF= 20. Groundwater Section Guidelines for the Investigation and Remediation of Soil and Groundwater. Leachability criteria provided by the State of North Carolina or calculated by Black & Veatch. · Where criteria from two or more of these sources were available, the most conservative value was selected. Comparison of these standards to the data presented in Section 1.3.13 resulted in the following general conclusions: • Aluminum: The leachability screening concentration of 72,0 IO mg/kg was not exceeded by any of the surface soil samples, and in only one of the subsurface soil samples. Therefore, aluminum has be eliminated as a groundwater protection COC. • Arsenic: For protection of groundwater and as stated in Section 6.2.8 of the HHRA in the OU I RI Report, arsenic was found in only a few of the surface and subsurface soil samples at concentrations exceeding the EPA leachability standard for protection of the groundwater value of 4.0 mg/kg which was calculated using default parameters. However, arsenic was not found in any of the groundwater samples at levels exceeding the MCL of IO µg/L except for one groundwater samples collected in October of 2002 from SS-MW-11 Cat a concentration of 26 µg/L. Therefore, arsenic has been eliminated as a groundwater protection COC. • Barium: Barium was not detected in groundwater above the MCL of2,000 µg/L even though as stated in Section 6.2.8 of the HHRA in the OU I RI Report, barium was found in eight surface soil locations and several deep boring locations in the lagoon exceeding the NC leachability standard for protection of groundwater of 241.8 mg/kg which was calculated using default parameters. Therefore, barium has been eliminated as a groundwater protection COC for surface and subsurface soil. • Lead: Based on the HHRA, lead was not identified as a COC for surface soil, subsurface soil, or groundwater. Although lead was detected in many of the soil samples across the site, the concentration of lead exceeded the groundwater protection value of 270 mg/kg only at SB-06 at a depth of 5 to 7 feet. Furthermore, low concentrations of lead I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I ·1 I I Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: 1 Revision No.: 0 December 14, 2006 Page 21 of26 generally less than 5 µg/L were found in the majority of wells; however, the only exceedances of the MCL (15 µg/L) were found at potable wells PW-09 and PW-IO and monitoring well MW-14. Both wells PW-09 and PW-10 are located upgradient of the Site. At well PW-09, lead was detected at 50 µg/L, 14A µg/L, 20J µg/L, and 4.3J µg/L. At well PW-I 0, lead was detected at a concentration of l 40J µg/L and l lJ µg/L. Lead was detected at a concentration of 16 µg/L in well MW-14, but this may be falsely high due to the high turbidity (380 Nephelometric turbidity units (NTUs]) of the sample. Based on subsequent risk management decisions with EPA and the State of North Carolina, the determination was made to not include lead as a groundwater protection COC. • Manganese: Although manganese was identified as a COC for groundwater in Section 6.2.7 of the HHRA in the OU I RI Report, further evaluation of both the historical and RI field investigation data revealed that manganese exceeded the EPA 's health advisory value of 300 µg/L in three of the Site monitoring wells. MW-I IC, MW-13B, and MW- 14 and five of the push point/temporary wells (PP-5, PP-7, PP08, TW-3, and TW-9). The concentration of manganese found in the three monitoring wells ranged from 5,200 to I 9,000 µg/L. The wells are all located in the southwestern area of the Site. Groundwater in this area generally flows to the south and southwest. The septic pits were located in the southern portion of the Site. Using the health advisory value of300 µg/L, a leachability standard for protection of groundwater of 391 mg/kg was calculated. The subsurface soil samples that exceeded this standard were found in the southern portion of the Site at concentrations ranging from 430 mg/kg to 1,300 mg/kg. The orientation and concentration of these subsurface soil samples suggest the possibility that the high level of manganese observed in the wells may be site related. It is also possible that the naturally occurring oxidation/reduction of chlorinated solvents located in the center of the southern portion of the Site resulted in the mobilization of manganese in this area. EPA and the State of North Carolina determined that manganese will not be a groundwater protection COC; however, the concentration of manganese in the groundwater will be monitored over time. • Mercury: Based on the HHRA, mercury was not identified as a COC for either surface or subsurface soil, but was preliminarily identified as a groundwater COC based on a North Carolina leachability standard of 0.015 mg/kg. Although mercury was detected in many of the subsurface soil samples in the southern half of the property above this groundwater protection number of 0.015 mg/kg with a maximum concentration of 1.6 mg/kg at SB-06 at a depth of 5 to 7 feet, mercury was only detected in two wells, potable well PW-03 and monitoring well MW-14. The federal MCL (2 µg/L) as well as the North Carolina MCL (I. I µg/L) were exceeded only at PW-03 (2. IA µg/L) during the 2002 sampling event but the mercury concentration at this well decreased to 0.98 µg/L in 2004 and 0.2 µg/L in 2005. Mercury was also found in well MW-14 at a Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 22 of 26 concentration of 44J µG/L in 2004 but this result may be falsely high due to the high turbidity (380 NTUs) of the sample. Based on this data, EPA and the State of North Carolina decided to eliminate mercury as a groundwater protection COC. • Vanadium: The EPA calculated leachability screening concentration of 900 mg/kg was not exceeded in any of the surface or subsurface samples. Based on this data, EPA and the State of North Carolina decided to eliminate vanadium as a groundwater protection coc. • Zinc: Based on the HHRA, zinc was originally identified as a COC for groundwater based on an EPA protection of groundwater leachability standard of 1,817.8 mg/kg: maximum concentrations found in surface soil were below this standard and just barely above this standard in a few locations in subsurface soil. Based on the fact that zinc was not found above the MCL of 5,000 µg/L in any of the wells, zinc was eliminated as a groundwater protection COC (Black & Veatch 2006b; EPA, 2006b ). Based on an evaluation of both the historical and RI field investigation data, and the previous discussions regarding both risk-based and protection of groundwater RGOs, (as presented in Table 1-18), EPA and the State of North Carolina have concluded that based on a human health risk to child, vanadium in both onsite and offsite surface soils at the Site is the only remaining COC requiring remediation at the Site (Black & Veatch 2006b; EPA, 2006b). Ecological Risk Assessnient EPA evaluated the potential for ecological risks at the Site. The ecological risk assessment addressed the objectives set forth by the National Plan, 40 Code of Federal Regulations 300, under Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) for protection of the environment from current and potential threats posed by an uncontrolled hazardous release (Black & Veatch 2006a; EPA, 2006b ). On July!, 2002, EPA completed a "Final" Screening-Level Ecological Risk Assessment (SLERA). The SLERA was based on data collected during the ESI conducted at the Site. The EPA collected additional data as part of the RI sampling investigation in October 2002. The additional data was evaluated to determine its impacts on the conclusions of the July 2002 SLERA. There were contaminants exceeding the concentrations reported in the July I, 2002, SLERA that would have affected the outcome of the SLERA. These included beryllium and thallium in surface soil. In addition, contaminants detected in the October I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: I Revision No.: 0 December 14, 2006 Page 23 of 26 2002 RI sampling event but not analyzed for in the July I, 2002, SLERA include 4,4'- dichlorodiphenyldichloroethane (ODD) and alpha-Chlordane in sediments: PCB-1260 in surface water; and numerous pesticides/PCBs and dioxins in surface soil. Based on a technical review of the SLERA performed for the Site and other pertinent information available at the time, it was concluded that ecological risk would not require further evaluation (Black & Veatch 2006a; EPA, 2006b ). 1.3.15 Feasibility Study: 2006 Potential remedial alternatives to address soil at the Site were identified, screened, and evaluated in the FS. The range of alternatives developed included the following: no action; institutional controls; containment, treatment, and disposal. Abbreviated soil alternatives are described below and a summary of soil alternatives is presented in Table 1-19 located in Appendix A (Black & Veatch 2006c; EPA, 2006b). Alternative Sl: NO ACTION. Regulations governing the Superfund program generally require that the "no action" alternative be evaluated to establish a baseline for comparison. Under this alternative, EPA would take no action at the Site to prevent exposure to the soil contamination. Since hazardous wastes would remain onsite, this alternative would require continued monitoring of the soil and periodic 5-Year. Reviews. The estimated time for implementation is less than I year, and the estimated total present worth is $78,000. Alternative S2: REMOVAL/TREATMENT: EXCAVATE, CHEMICALLY STABILIZE HIGHLY CONTAMINATED SOIL, AND DISPOSE OF THE CONT AMINA TED SOIL ONSITE. This alternative consists of the excavation of all soils above site cleanup goals, consolidation and treatment of excavated soils that fail TCLP using . solidification/stabilization pursuant to applicable treatment standards under 40 Code of Federal Regulations (CFR) 268, and onsite disposal. It is assumed that 25 percent of the total contaminated soil volume is highly contaminated and will require solidification/stabilization treatment prior to onsite land disposal. Solidification/stabilization treatment includes thoroughly mixing a chemical reagent or chemical mixture into the contaminated soil to initiate a chemical reaction that (a) chemically or physically alters the contaminant(s) into a less mobile form or (b) solidifies the soil-chemical mass into an inert matrix. The treated and untreated soil would be disposed into an appropriate onsite disposal area meeting Field Sampling Plan Section: I Revision No.: 0 December 14, 2006 Page 24 of26 EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site requirement for RCRA Subtitle D non-hazardous waste disposal. The onsite disposal area will be capped with a 1-foot soil layer and grass cover. Institutional controls such as fencing and deed restrictions may be implemented for the onsite disposal area. The soil and vegetative cap will be maintained throughout the life of the remedy. The estimated time for implementation is 1 year, and the estimated present worth cost is $2,000,000. Alternative SJ: EXCAVATION, CHEMICALLY STABILIZE HIGHLY CONTAMINATED SOIL, AND OFFSITE TRANSPORTATION AND DISPOSAL AT A SUBTITLED LANDFILL. The major components of this alternative include: • • • • • Excavation of surface and subsurface soil containing COCs above site-specific remedial goal concentrations; Treatment to meet applicable treatment standards under 40 CFR 268 using solidification/stabilization of soils that fail TCLP; Offsite transportation and disposal of the treated and untreated soil at an offsite RCRA Subtitle D landfill; Backfill the excavated areas with clean borrow material obtained from a local source; and Re-vegetate and restore site to safe and usable conditions . This alternative is similar to Alternative S2 except that the treated and untreated soil will be disposed at an offsite RCRA secured Subtitle D landfill meeting the requirements for RCRA Subtitle D non-hazardous waste disposal. It is assumed that 25 percent of the soil is highly contaminated and will require solidification/stabilization treatment prior to disposal. This alternative will remove all soil exceeding the site-specific cleanup goals from the Site and adjacent properties. The excavated areas will be backfilled with clean soil and re-vegetated. Deed restrictions may be placed on the Site while the remedial action takes place. Water would be used to minimize dust emissions during soil excavation, transport, and handling. The re-vegetated areas will be monitored and maintained on a quarterly basis for the first 3 years to ensure survival of the vegetation. The estimated time of completion is I year and the estimated present worth cost is $2,200,000. Comparative Analysis. A comparative analysis was conducted to compare and contrast the alternatives so that decision makers may select a preferred alternative for presentation in the I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I .1 I I I I I I Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence ,2) Site Section: I Revision No.: 0 December 14, 2006 Page 25 of 26 Record of Decision (ROD). The comparative analysis is evaluated based on the threshold criteria (Overall Protection of H~man Health and the Environment; Compliance with ARARS) and balancing criteria (Long-Term Effectiveness and Performance; Reduction of Mobility/ToxicityN olume [M/TN]; Short-Term Effectiveness; Implementability; and Cost). Table 1-20 located in Appendix A presents a summary of each soil remedial alternative along with ranking scores for each evaluation criteria. Each alternative's performance against the criteria ( except for cost) was ranked on a scale of O to 5, with O indicating that none of the criterion's requirements were met and 5 indicating all of the requirements were met. The ranking scores are not intended to be quantitative or additive, but rather are only summary indicators of each alternative's performance against the CERCLA evaluation criteria. The ranking scores combined with the present worth costs provide the basis for comparison among alternatives. Alternatives 2 and 3 rank higher than Alternative I in overall protection of human health and the environment, compliance with ARARs, long-term effectiveness and permanence, and reduction of M/TN. Alternative 3 ranks slightly higher than Alternative 2 in compliance with ARARs, long-term. effectiveness and permanence, and implementability. Alternative 2 ranks slightly higher than Alternative 3 in short-term effectiveness (Black & Veatch, 2006c; EPA, 2006b). 1.3.16 Proposed Plan: 2006 The Proposed Plan for the Site was published in a Proposed Plan Fact Sheet that invited comments from citizens potentially affected by the Site who were mailed the fact sheet via the U.S. Postal Service. The comment period for the fact sheet was from June IO through July 10, 2006, with the Proposed Plan meeting conducted on June 22, 2006. The fact sheet provided a brief history of the site, presented the FS alternatives for the Site considered by EPA, outlined the criteria used by EPA to recommend an alternative for use at the Site, provided a summary of the analysis of the alternatives, informed the public that the EPA was proposing to issue a ROD for OU I for the Site, and explained the opportunities for the public to comment on the remedial alternatives. EPA's preferred alternative identified in the fact.sheet was Alternative S3 -Excavation, Chemically Stabilize Highly Contaminated Soil, and Offsite Transportation and Disposal at a Subtitle D Landfill (Black & Veatch, 2006d). Field Sampling Plan Section: I Revision No.: 0 December 14, 2006 Page 26 of26 EPA Contract No. 68-W-99--043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site 1.3.17 Record of Decision (ROD): 2006 The ROD presents the selected remedy for the Site for OU 1. This OU action is the first for the site. It specifically outlines an action to address contaminated soils (including the stockpiles), sediments, and surface water. The ROD indicates that further investigation is needed to characterize the extent of groundwater contamination before a groundwater ROD can be issued. The principle threat wastes at the site for OU 1 consist of contaminated soils above Remediation Goals (RGs) that fail the TCLP. The principle threat wastes will be excavated and treated pursuant to RCRA treatment standards ( 40 CFR 268) through solidification/stabilization prior to offiste land disposal. The cleanup strategies will address threats, removal of principal threats through source control, treatment, and offsite disposal. A portion of the contaminated soil will be excavated and disposed in an offsite landfill without treatment. The major components of the selected remedy for OU I include: • • • • • Excavation of surface and subsurface soil containing COCs above site-specific remedial goal concentrations. Contaminated soils that fail the TCLP will be treated to meet applicable treatment standards under 40 CFR 268 using solidification/stabilization (SIS) technologies. Offsite transportation and disposal of the treated and untreated soil at a RCRA Subtitle D Landfill. Backfill the excavated area with clean borrow material obtained from a local source. Re-vegetate and restore site to safe and usable conditions . The selected remedy is protective of human health and the environment, complies with federal and state requirements that are ARARs to the remedial action, is cost effective, and utilizes permanent solutions and alternative treatment ( or resource recovery) technologies to the maximum extent practicable. The selected remedy satisfies the statutory preference for treatment as a principal element of the remedy (i.e., reduces the toxicity, mobility, or volume of hazardous substances as a principle element through treatment). Upon completion of the remedy, no hazardous substances will remain onsite above levels the prevent unlimited use and unrestricted exposure. Therefore, no 5-year review will be required for this OU I (EPA, 2006b).

As discussed in the October 30, 2006 scoping meeting, this investigation will focus on collecting groundwater samples from existing monitoring wells, previously sampled private potable wells, newly installed deep monitoring wells, and additional private potable wells in areas up gradient and outside of the valley of the site location, to facilitate establishing a background study. Sample locations are described in Table 3-1 included on Figure 3-1. Groundwater samples will be collected from existing shallow wells ( 4) and deep monitoring wells (I) and private potable wells (8) that were previously sampled and included in the Sigmon's Septic Tank Site· QUI investigation completed in 2006. A total of twenty two additional private potable wells are proposed to be sampled on Bigtree Drive and outside of the Sigmon's valley in the 500 to 800 block ofEufola Road, 1600 to 1900 block of Buffalo Shoals Road, and 1500 to 1600 block of Old Mountain Road to characterize the background · water quality. Three new deep monitoring wells located around the Sigmon's pond are also proposed. The initial mobilization sampling event will include surveying existing locations of private and monitoring wells for Northing and Easting, and elevations of all monitoring wells, private potable well and monitoring well sampling, installation, sampling and slug testing of the additional permanent monitoring wells in the deep portions of the fractured bedrock aquifer. A final mobilization will be required to perform oversight of investigation-derived waste (IDW) disposal. The following discussion of the work at the site is based upon available information and an initial technical approach to fulfilling the EPA SOW, dated October 18, 2006. The technical approach, including the type and numbers of environmental samples collected, the methods of chemical analyses, sampling locations, and the procedures for dealing with the IDW are subject to change pending further discussions between the EPA, Black & Veatch, Black & Veatch's subcontractors, and any other relevant parties. If any deviations to the Final FSP are necessary, EPA approval must first be obtained and documented.

The objectives will be accomplished by collecting private potable well samples upgradient, out of the valley to the east and northeast of the site. Deep monitoring well samples will be collected around the Sigmon's pond. A total of 38 groundwater samples will be collected for environmental analyses ( excluding duplicates samples and samples for quality control/quality assurance [QNQC] purposes) and submitted to selected CLP laboratories or the EPA SESD laboratory for analysis. The following samples are proposed: • • • • , Five existing monitoring wells ( 4 shallow and I deep) Eight previously sampled private potable wells Three deep monitoring wells (at depths greater than 90 feet below land ~ac.<Q_around the Sigmon's pond. ~ty-@~ additional private wells (2 wells on Bigtree Drive; 7 wells outside•of-the Sigmon's valley in the 500 to 800 block of Eufola Road; 7 wells in the 1600 to 1900 block of Buffalo Shoals Road, and 6 wells in the 1500 to 1600 block of Old Mountain Road). A hand held global positioning system (GPS) unit will be used to document the location of all new sample locations at the site. New monitoring well elevations will be surveyed during later field investigation activities. Samples and analytical parameters are described in greater detail in the following sections. The proposed sampling locations are listed in Table 3-1 and are identified on Figure 3-1.

The additional private potable wells will be surveyed using a GPS unit at the time of sample collection. The private potable well samples will be analyzed for the EPA CLP parameter groups and accepted analytical field methods. These include: • • • • Multi-Media, Multi-Concentration Organic Analytical Service for Superfund (SOMO 1.1) (EPA, 2006c) for the following: volatile organics (trace water); semi volatile organics (low water); and pesticides/PCBs (water) found on the target compound list (TCL). Multi-Media, Multi-Concentrntion Inorganic Analysis, ILM05.3 (EPA, 2004c) inductively coupled plasma-atomic emission spectroscopy(ICP-AES) for water for metals and cyanide found on the target analyte list (TAL). Monitored natural attenuation (MNA) parameter analysis will be analyzed for sulfate (EPA Method 375.4). Field methods will be used for the analysis of pH, temperature, turbidity, conductivity, dissolved oxygen (DO), oxidation/reduction potential (ORP), ferrous iron, and sulfide. The owner's names and addresses for the residences where the private potable well samples will be collected will be submitted to EPA. No sampling will be performed without a signed access agreement. Each private potable well sample will be collected in accordance with the procedures described in Section 5.4 of the FSP. A summary of samples, analyses, and containers is presented in Table 3-2. Table 3-3 contains a summary of the quality control samples, analyses, and containers. The list of homeowners is presented in Table 3-4. Prior to collection of groundwater samples from the private potable wells, the wells must be purged in accordance with the following procedures: Ideally, the sample should be collected from a tap or spigot located at or near the well head or pump house and before water supply I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Field Sampling Plan EPA Contract No. 68-W.Q43 Section: 3 Revision No.: 0 December 14, 2006 Page 4 of6 Work Assignment No. 693-RICO~A44F Sigmon's Septic Tank Site is introduced into any storage tanks or treatment units. Ideally, the system should be purged for at least 15 minutes. After purging for several minutes, the water quality parameters should be measured. If turbidity is not below IO NTU after other parameters have been stablized, purging will continue until this objective is achieved or the turbidity has been reduced as much as possible using the least disruptive sampling method possible. As requested by EPA during the Scoping Meeting held on October 30, 2006, the turbidity of the sample will be measured immediately prior and after sample collection. 3.1.2 Monitoring Well Groundwater Sampling A total of 8 monitoring well samples (5 existing [I shallow and 4 deep] and 3 newly installed . deep wells) will be sampled. The 3 deep wells are proposed to be installed at depths greater than 90 feet bis to the east, west, and south of Sigmon's Pond. The shallow wells were screened in the shallow surficial aquifer (estimated to be 30 to 40 feet bis at the site), the deep surficial well (MW-138) was screened in the deep portion of the surficial aquifer ( estimated to be 70 to 80 feet bis), and the fractured rock aquifer wells will be installed in the fractured bedrock underlying the surficial aquifer (estimated to be 100 to 110 feet bis). Groundwater samples collected will be analyzed for the EPA CLP parameter group and accepted analytical meth.ods. These include: • • • Multi-Media, Multi-Concentration Organic Analytical Service for Superfund (SOMO 1.1) (EPA, 2006c) for the following: volatile organics (trace water); semi volatile organics (low water); and pesticides/PCBs (water) found on the target compound list (TCL). Multi-Media, Multi-Concentration Inorganic Analysis, lLM05.3 (EPA, 2004c) ICP-AES for water for metals found on the target analyte list (TAL). MNA parameter analysis will be analyzed using the following methods: alkalinity(EPAMethod 310.2); total organic carbon (TOC) (SW-846 Method 9060); nitrate/nitrite/nitrogen and TKN (total Kjeldahl nitrogen) (EPA Method 300 or 353.2 and 365. !); chloride (EPA Method 352.2); sulfate ((EPA Method 375.4); and methane/ethane/ethene (EPA SESD Method ASBVI00). Field Sampling Plan EPA Contract No. 68-W-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank Site Section: 3 Revision No.: 0 December 14, 2006 Page 5 of6 • Field methods will be used for the analysis of pH, temperature, turbidity, conductivity, dissolved oxygen (DO), oxidation/reduction potential (ORP), ferrous iron, and sulfide. Prior to collection ofa groundwater sample from a monitoring well, the well must be purged in accordance with procedures described in Section 5.4 of this FSP. With respect to volume, an adequate purge is normally achieved when three to five times te volume of standing water in the well has been removed (EPA, 200 I). A summary of the monitoring well samples, analysis, and containers is presented in Table 3-2. A summary of the quality control samples, analyses, and containers is presented in Table 3-3. If turbidity is not below IO NTUs after other parameters have been stablized, purging will continue until this objective is achieved or the turbidity has been reduced as much as possible using the least disruptive sampling method possible. As requested by EPA during the Scoping Meeting held on October 30, 2006, the turbidity of the sample will be measured immediately prior and after sample collection. Water level reading will be collected at each monitoring well location prior to purging so that groundwater flow direction and groundwater potentiometric surface can be estimated. Proposed monitoring well installation and sampling locations and rationale are described in Table 3-1 and are presented on Figure 3-1. 3.1.3 Groundwater Level Measurements Water level measurements will be obtained from the eight monitoring wells. Groundwater levels will be measured in accordance with procedures described in Section 5.4.2 of this FSP. This data will be used to develop potentiometric surface maps for the site area and will assist in understanding the general groundwater flow direction. 3.1.4 Slug Testing To estimate hydraulic conductivity of the aquifer in order to evaluate the potential rate of contaminant migration, slug tests will be performed on three existing wells that have not been previously slug tested (SS-MW-l0B; SS-MW-14; SS-MW-15) and on the three new I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Field Sampling Plan EPA Contract No. 68-W-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank Site Section: 3 Revision No.: 0 December 14, 2006 Page 6 of 6 wells installed and the fractured bedrock aquifer. Data gathered from these tests will assist in estimating area hydraulic conductivity. The hydraulic conductivity values that are obtained will be compiled with existing values and evaluated for the site. This data will be used to determine rate of potential contaminant migration. 3.1.5 Sampling QA/QC As part of the sampling effort, QC samples will be submitted to the laboratory with field investigation samples in order to evaluate the confirmatory sampling procedures and analytical methodologies. A discussion of the types of samples to be collected is presented in Section 4.4.4 of the QAPP. Approximately five percent of the field investigation samples will be collected in ·order to evaluate sampling handling, shipment, and laboratory procedures. A summary of the QC samples, analyses, and containers is presented in Table 3-4. 3.1.6 Surveying During the field investigation, all newly installed wells and the additional potable wells will be surveyed using a GPS unit and more precise methods. Northing and Easting coordinates will be surveyed for all monitoring wells; the ground elevation and the elevation of the top of casing point from which water level measurements are collected will also be surveyed. The Northing and Easting coordinates will be measured to the nearest 0.1 meter. The Northing and Easting coordinates will be North America Datum 1927 (NAD27), Universal Tranverse Mercator (UTM) meters, Zone 17. Elevations will be recorded to within the nearest 0.0 I foot. 3.2 IDW Disposal lDW disposal oversight will be conducted after all field investigation_ activities that generate IDW have been completed. IDW disposal oversight is tentatively scheduled for August 2007. Drums of IDW will be addressed as specified in Section 7.0 of this FSP.

Specific field procedures· and methods have been selected for use in order to ensure that sampling and data collection activities are conducted within acceptable QA standards. Additional information concerning QA protocols is presented in the QAPP. 5.1 Summary of Sampling Program Groundwater samples will be collected from locations within and near the Sigmon's Septic Tank (Sequence 2) Site as described in Section 3.0. All samples, will be analyzed by the following EPA CLP accepted methods: SOMO 1.1 (volatile organics; semi volatile organics; and pesticides/PCBs); and ILM0S.3 (metals and cyanide) (EPA, 2004c; EPA, 2006c). The objective of the sampling and preservation procedures outlined in this FSP is to obtain samples which yield consistently high quality. The use of proper sampling equipment, strict controls in the field, and appropriate chain-of-custody and analytical procedures will reduce the potential for sample misrepresentation and unreliable analytical data. Specific sampling and preservation procedures to be used in the field investigation_ are detailed in _the following sections. The EPA Environmental Investigations Standard Operating Procedures and Quality Assurance Manual (EISOPQAM) will serve as the primary document from which all field procedures will be developed (EPA, 2001). Container, preservation, and holding time requirements must also meet the requirements of the EISOPQAM (EPA, 2001). The analytical methods selected and/or modified will have detection limits that are less than, or equal to, federal MCLs and state regulatory levels. All contractor personnel conducting sampling will be experienced in implementing the sampling procedures as outlined herein. Modifications and/or changes to the procedures described in the EISOPQAM or the standard operating procedures (SOPs) presented in this FSP will not be implemented without the prior approval ofEP A and will be documented in field logbooks and on the Field Change Request Form presented as Figure 4-1 in the QAPP.

Groundwater development and purging/sampling activities will also be recorded in the field logbook and on a Well Development Log and a Groundwater Sample Collection Record as presented on Figures 3-2 and 3-3, respectively, in Section 3.6 of the QAPP. 5.2.1 Monitoring Well Construction, Installation, and Completion It is anticipated that at each new fractured bedrock .well will be drilled.to approximately 110 feet deep in the fractured bedrock aquifer and screened using a I 0-foot screen. The depth of the wells will be based upon lithology encountered. Previously installed monitoring wells indicate the water table may be present at a depth of 25 to 30 feet bis in the site area. The fractured bedrock aquifer wells will adjusted to staddle the fractured bedrock. Well drilling, completion, and development will be conducted in accordance with the standards established in the EISOPQAM (EPA, I 997). The proposed monitoring well locations are presented in Section 3.0 of this FSP. Permits to install and construct the monitoring wells will be secured from the appropriate authorities by Black & Veatch's drilling subcontractor prior to commencement of drilling activities. 5.2.1.1 Permanent Monitoring Well ConstructioaThepermanentmonitoringwells within the site area will be installed by Black & Veatch's drilling subcontractor. Due to the depths of the samples, rotary methods will be used to allow collection of representative samples. Historically, drilling with hollow stem augers is the preferred method because it does not introduce fluid into the borehole. It is anticipated that if surface casings are required hollow stem augers may be utilized. However, rotary or Rotasonic methods may be used if conditions are such that hollow stem augers are not adequate or if other methods are adequate and (after subcontractor bidding) prove more cost effective. If problems arise from sand entering the hollow stem augers (heaving sands), rotary methods will be used to allow collection of representative samples. Heaving sands entering the augers prevent the collection ofrepresentative samples with split spoons. Rotary methods maybe used in conjunction with hollow stem augers for installing the surface casing. While 6 ¼-inch ID hollow stem augers may result in a nominal IO-inch I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: 5 Revision No.: 0 December 14, 2006 Page 3 of 12 diameter borehole, difficulty in keeping the annular space open before grouting in the surface casing may be a problem. Rotary methods will be used as an alternative ifhollow stem auger drilling is used and proves ineffective. Drilling procedures for hollow stem auger, rotary, and sonic drilling are described below. Hollow Stem Auger Drilling The preferred drilling method is hollow stem auger. An initial pilot borehole shall be drilled using 4 ¼-inch ID hollow stem augers. This pilot hole will be used to collect split spoons samples for chemical analysis and lithologic description. For shallow monitoring wells, the pilot hole will be advanced to total depth without a surface casing. After the pilot hole is complete, the borehole will be reamed with plugged 6 ¼-inch ID hollow stem augers to total depth. The bottoin of the lead 6 ¼-inch ID hollow stem augers will be plugged with a fitted Teflon® plug that will be knocked out upon well installation. Upon reaching total depth with the plugged 6 ¼-inch hollow stem augers, the well will be installed as described in Section 5.4.1.2. Rotary Drilling Rotary drilling will be the presumptive method for construction of monitoring well in the fractured bedrock aquifer. After advancing the boring with 4 1/4-inch hollow stem augers to collect soil samples using split spoons, the boring for the permanent monitoring well may be advanced by rotary drilling using a nominal 10-inch outside diameter (OD) tri-cone or roller bit (rotary bit) to install the surface casing, and a nominal 6-inch OD tri-cone or roller bit thereafter. Air or wash rotary will be used if possible; however, mud rotary will be used in the event there is loss of circulation or drill cuttings are not circulating adequately. If mud rotary is used, the borehole shall be flushed with potable water before well installation. For the borehole designated for the fractured bedrock aquifer well, the borehole hole will continue with split spoon sampling at 5-foot intervals until the fractured bedrock unit is encountered. When the fractured bedrock unit is encountered below the water table, drilling with the 10-inch rotary bit will continue approximately 3 feet into the bedrock and then cease until surface casing is installed. After the surface casing is installed, the borehole will be advanced to total depth with the nominal 6-inch OD rotary bit. For shallow monitoring wells, the nominal 6-inch bore hole will be advanced to total depth without a surface casing.

Sonic Drilling (Rotosonic™) If Rotosonic™ drilling is used, the installation of a permanent surface casing will not be required. Rotosonic™ drilling involved advancing a 4-inch diameter core barrel for soil sample removal. The 4-inch ID core barrel is advanced in I 0-foot segments. Upon reaching the IO-foot increment, a 6-inch ID (override) core barrel is placed over the 4-inch core barrel and advanced to the same depth as the 4-inch core barrel. With the 6-inch core barrel still in place, the 4-inch core barrel is removed and the sample is removed and placed into 5-foot long plastic sleeves for examination by the onsite geologist. If a competent clay layer or other confining layer is encountered between the water table and the desired screened interval, an 8-inch override casing is advanced over the 6-inch override casing and left in place as the borehole is advanced using the 4-inch and 6-inch system. The 8-inch override casing, if required, shall be installed approximately 3 feet into a low permeability zone in order to isolate potentially contaminated groundwater in the upper portion of the shallow aquifer from the underlying groundwater. The 8-inch override casing will be pressurized to insure an adequate seal exists. If it is discovered there is not an adequate seal, a bentonite plug will be installed around the 8-inch override casing before advancing the borehole. Before advancing below the 8-inch casing the borehole will be flushed and the 4-inch by 6- inch equipment will be decontaminated to prevent dragging contamination downward. Upon removing the 4-inch, 6-inch, and possible 8-inch casings, the annular space between the borehole wall and the well casing will be grouted using a 30 percent high solids bentonite grout (Volclay Pure Gold® is the only brand currently accepted) as the casings are withdrawn. The actual depth of casing installation will be determined in the field by the onsite geologist. 5.2.1.2 Well Installation. Construction details for the proposed monitoring wells described herein are detailed on Figure 5-1. A Well Installation Log will be generated for each well installed. Upon reaching total depth, well installation will begin. If mud rotary drilling is required, the borehole will be back-washed with potable water to remove drilling mud from the borehole before well installation begins. The placement of the screened interval will be dependent on the depth of the water table and the depth to the top of the fractured bedrock aquifer. It is anticipated that the top of the screened interval for the fractured bedrock aquifer well will be at approximately I 00 feet bis.

The wire-wrapped well screens (0.010-inch slot size) will be 10 feet in length and shall be fitted with a threaded stainless steel bottom plug. A filter pack will be placed per the EISOPQAM, a minimum of six inches below the screen and a minimum of 2 feet above the screen using prewashed silica sand. The filter pack will be applied by tremie method (unless Rotosonic™ drilling methods are used) a minimum of 12 inches under the bottom of the well plug and will extend up to no less than 2-feet above the top of the well screen. IfRotosonic™ drilling is used, the filter pack will be poured into the annular space between the 6-inch casing and the well casing and vibrated into place. Bentonite pellets (1/4 inch diameter or less) will then be placed down the annular space to provide a pre-hydrated seal no less than two feet thick above the sand pack. The bentonite pellet seal is anticipated to lie below the water table, and should not require manual hydration. Depths to the top of the sand pack and the top of the bentonite seal will be measured using a weighted tape or a measured tremie line. The remaining annular space will be grouted by tremie pipe to within approximately two feet of the surface with a bentonite grout composed of Pure Gold® bentonite powder and potable water (measured weight of the bentonite grout is to be no less than IO pounds per gallon using a drilling contractor supplied mud balance). IfRotosonic™ drilling is used, the 4-inch, 6-inch, and 8-inch override casings will be removed as the borehole is grouted. !fa permanent surface casing is required, hollow stem auger or rotary drilling techniques will be used to advance a 10-inch borehole approximately 3-feet into the fractured bedrock unit. Once the borehole is completed, a nominal 6-inch ID carbon steel permanent surface casing will be lowered into the borehole for grouting. Permanent casing will consist of black steel pipe, seamless or welded, in accordance with American Petroleum Institute Standard SL or equivalent American Society of Testing and Materials (ASTM) or American National Standards Institute (ANSI) standards. The full-length casing will be new six-inch nominal inside diameter black steel pipe with the wall thickness of not less than 0.25 inch. The grout used to secure the surface casing will be bentonite cement consisting of 6.5 to 7 gallons of water per 94-pound bag of Type I Portland cement with 5 to 10 percent by weight of bentonite powder. The mixed grout will be weighed with a mud scale before pumping. The grout will be installed using a tremie pipe to install grout through the annular space between the borehole wall and the surface casing. When using the tremie method, the Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: 5 Revision No.: 0 December 14, 2006 Page6ofl2 surface casing will be plugged approximately 2 feet from the bottom to prevent the entire inside length of the casing from being grouted and to keep out any potentially contaminated formation soil or water. This temporary plug may be polyvinyl chloride (PVC) or bentonite. Approximately 2 feet of grout will be pumped into the bottom of the borehole immediately before lowering the casing. After the casing is lowered, a tremie pipe will be used to pump grout into the annular space between the surface casing and the borehole wall. Grout will be tremie grouted into the annular space until grout returning from the annular space at land surface is equal in weight to that being pumped. Advancement of the 6-inch borehole through the surface casing will not begin until the grout used to secure the surface casing has cured for at least 24 hours. 5.2.1.3 Well Completion. Drill cuttings and fluids which result from the well installation process will be containerized in Department of Transportation (DOT)-approved 55-gallon UN IA-I or IA-2 drums. The monitoring wells will be sealed to the ground surface with concrete and a minimum 3-foot by 3-foot by 6-inch thick concrete surface pad that slop~s away from the center of the pad and protective casing. A lockable protective casing, approximately 4-inch by 4-inch by 3-foot or a flush mounted, traffic rated steel cover with locking well cap, will be installed in the concrete to provide wellhead security. In order to diminish anticipated well-head corrosion problems, the protective casings will be constructed of aluminum, steel, or cast iron and painted with rust-resistant paint. Keyed-alike locks will be used to secure the wells. The stick-up protective casings will have one weep hole to prevent water from standing inside of the protective casing. In addition, four 3-inch diameter (minimum) concrete-filled steel posts will be placed adjacent to each concrete pad as bumper guards to protect the aboveground protective casings. The posts shall be a minimum of five feet in length and extend approximately three feet above the surface. 5.2.2 Groundwater Level Measurements After unlocking the monitoring well and removing the cap, the ambient air will be monitored using an organic vapor analyzer (OVA) to evaluate the presence of organic vapors. A decontaminated, electric water level indicator will then be placed into the monitoring well to measure the depth to the static water level and total depth of the well. The meas·urement will be recorded to the nearest 0.01 foot and will be taken from a reference notch at the top of the monitoring well casing. The water level measurement and total depth measurement for the monitori_ng well will be used to calculate purge volumes.

A steel tape will be introduced through the well cover, or by removing a single bolt in the well cover, or by simply passing the tape through a crack, slot, or separation in the cover. The water level is measured by suspending a known length of tape below a datum mark so that the lower few feet of the tape are below water level. The lower portion of tape is coated with blue chalk or some other substance that exhibits a marked color change when wetted. The water level measurement is obtained by subtracting the length of the wetted portion from the total length suspended below the datum mark (Garber, 1978). Prior to disturbing the well, the power will be shut offal the switch. A complete set of water level measurements from all wells and the surface water bodies will be taken within a 24-hour period to construct groundwater flow maps. 5.2.3 Monitoring Well Development The newly installed permanent groundwater monitoring wells will be developed by Black & Veatch prior to initiating groundwater sampling. Development of the well will occur no sooner than 24 hours after installation of the surface pad. Development of the wells will . involve mechanical surging using either a 1.25-inch outside diameter outside diameter (OD) tremie pipe with an end cap or a 1.25-inch OD solid PVC block and pumping to remove fines and stimulate yield. The monitoring wells will be developed until the water in the well is free of visible sediment, and the pH, conductance, turbidity, and temperature have stabilized as demonstrated by three consistent readings (EPA, 200 I). Purge and development fluids will be contained in 55-gallon drums until proper disposal methods can be determined based on analytical results. Equipment utilized for monitoring well development will be decontaminated in accordance with procedures specified in Section 5.3 of this FSP. During the monitoring well development process, specific conductivity, pH, turbidity, and temperature measurements will be recorded in the field logbook. During the development process, water will be withdrawn, typically every 20 gallons, from the monitoring well and poured into a clean glass container. The temperature, specific conductivity, pH, and turbidity measurements will be measured immediately. All probes will be rinsed with organic free water. Turbidity will be measured in accordance with the turbidity meter manufacturer's specifications. Instruments used to measure field parameters during well development will be calibrated prior to each use. Well development activities Field Sampling Plan EPA Contract No. 68· W •99-043 Work Assigtlment No. 693•RICO•A44F Sigmon's Septic Tank (Sequence 2) Site Section: 5 Revision No.: 0 December 14, 2006 Page 8 of 12 will also be recorded on a Well Development Record as presented in Section 3.6, Figure 3-2 of the QAPP. 5.2.4 Monitoring Well Purging The permanent monitoring wells located within the site area will be purged immediately prior to initiating groundwater sampl_ing in order to remove the stagnant water from the well. The water removed from the well will be replaced with groundwater from the formation, which is representative ofaquifer conditions. The procedure for purging the monitoring well is described in accordance with the EISOPQAM (EPA, 2001). Note that a low-flow purge rate will be used to remove water from the monitoring wells. Prior to initiating purging, the total amount of water in the well must be determined from the diameter of the well, water level, and total depth. The volume of water in each well will be the following equation (used for 2-inch well casings): V = 0.041 d2h where: V = volume of water (gallons) d = diameter of well (inches) h = depth of water (feet) Monitoring wells will be purged using a decontaminated submersible pump or a peristaltic pump equipped with single-use Teflon® tubing. The pump intake line will be placed slightly below the top of the water surface in order to pull water from the entire length of the water column. During monitoring well purging, specific conductivity, pH, turbidity, DO, redox potential, and temperature measurements will be recorded in the field logbook and on the Groundwater Sample Collection Record presented on Figure 3-2, Section 3.6 of the QAPP. Purging will terminate when a minimum of three well casing volumes have been withdrawn from the monitoring wells, and field parameter readings have stabilized (pH readings within 0.1 units, specific conductance within IO percent, turbidity less than 10 NTUs, temperature within IO percent, and DO within IO percent) over four consecutive readings or upon evacuating five well volumes from each well if turbidity is less than 10 NTUs (if possible).

Water from well purging will be disposed of as discussed in Section 7 .0. Equipment used for purging will be decontaminated in accordance with procedures specified in Section 5.3 of this FSP, except for the single-use tubing which will be discarded after use. All field measurement equipment probes will be rinsed with organic free water. 5.2.5 Groundwater Sampling After each well within the site area has been purged, the well will be sampled for groundwater. Wells will be sampled using a low-flow peristaltic pump equipped with single- use Teflon® tubing and a vacuum jug, where applicable. The Teflon® tubing will be gently placed into the well slightly below the top of the water surface in order to pull water from the entire length of the water column. All of the groundwater sample containers, with the exception of the volatile organic compound (VOA) vials, will be filled using an in-line vacuum system with a low-flow peristaltic pump. This is accomplished by placing a Tefloif transfer cap onto the neck of a standard cleaned amber glass jug. The Teflon® tubing will connect the glass jug to both the well and the pump. The pump will create a vacuum in the jug, thereby drawing water from the well into the jug. The volatile organic portion of the sample will be collected after the other containers have been filled by first disconnecting the vacuum jug assembly from the peristaltic pump .. The Teflon® tubing will be lowered into the well and a gloved thumb placed over the end at the surface. The Teflmf tubing will then be removed from the well and allowed to drain directly into the VOA vials. In the event that groundwater is present at a depth too great to use a peristaltic pump, groundwater samples will be collected using a submersible pump, decontaminated prior to each use, or a Teflon® bailer. Container requirements along with preservation procedures and holding times are presented in Section 6.0, Table 6-1 of this FSP. Samples for chemical analyses will be placed in iced coolers. The field team leader (FTL) will be responsible for examining the samples and Field Sampling Plan ~PA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank (Sequence 2) Site Section: 5 Revision No.: 0 December 14, 2006 Page !Oof 12 logging all observations. Samples will be labeled, packed, and shipped in accordance with the procedures specified in the Section 4.3 of the QAPP. 5.3 Decontamination Procedures Procedures for equipment decontamination will be . implemented to avoid cross- contamination of surface and subsurface strata and samples of various media which are to be submitted for chemical analyses. Decontamination procedures will meet or exceed the requirements of the EISOPQAM (EPA, 2001). One decontamination station will be constructed during the course of the field work. The decontamination station location will be selected by Black & Veatch. All sampling equipment will be cleaned between sample locations. Prior to mobilizing to any permanent monitoring well location, the drill rig should be cleaned of any contaminants that may have been transported from another hazardous waste site, to minimize the potential for cross-contamination. If potable water is not readily available at the decontamination station, tap water (potable) brought on site for drilling and cleaning purposes should be contained in a pre-cleaned tank of sufficient size so that drilling activities can proceed without having to stop and obtain additional water. The drill rig and other equipment associated with the drilling and sampling activities will be inspected to ensure that all oils, greases, hydraulic fluids, etc., have been removed, and all seals and gaskets are intact with no fluid leaks. In addition, associated drilling and decontamination equipment, well construction materials, and equipment handling procedures will meet the following minimum specified criteria modified from the EISOPQAM: • All downhole augering, drilling, and sampling equipment should be sandblasted before use if painted, and/or there is a buildup of rust, hard or caked matter, etc., that cannot be removed by steam cleaning (soap and high pressure hot water), or wire brushing. Sandblasting should be performed prior to arrival on site, or well away from the decontamination pad and areas to be sampled. • Any portion of the drill rig, backhoe, etc., that is over the borehole (kelly bar or mast, backhoe buckets, drilling platform, hoist or chain pulldowns, spindles, cathead, etc.) will be steam cleaned (soap and high pressure hot water) and wire brushed (as needed) to remove all rust, soil, and other material which may have come from other hazardous waste sites before being brough on site.

Printing and/or writing on well casing, tremie tubing, etc., shall be removed before use. The decontamination station will be constructed at a suitable on-site location. In general, the station will be covered with a durable liner (such as a fiberglass reinforced tarp) such that decontamination fluids can flow into a lined collection pit, sump, or trench. The bottom of the pit should be lined with plywood to keep equipment from tearing the lining. Fluids generated as a result of decontamination will be dispersed onsite within the contaminated soil area. Decontamination station sheeting will be removed and placed in drums when decontamination activities have been completed. Two levels of equipment decontamination shall be utilized during the field investigation. Method I will be used for all equipment that will come into contact with analytical samples. Method II will be used for all downhole and related equipment. Method I: The following procedures are to be used for all sampling equipment used to collect routine samples undergoing trace organic or inorganic constituent analyses: I. Clean with tap water and soap using a brush if necessary to remove particulate matter and surface films. Equipment may be steam cleaned (soap and high pressure hot water) as an alternative to brushing. Sampling equipment that is steam cleaned should be placed on racks or saw horses at least two feet above the floor of the decontamination pad. PVC or plastic items should not be steam cleaned. 2. Rinse thoroughly with tap water. 3. Rinse thoroughly with analyte free water. 4. Rinse thoroughly with pesticide grade isopropanol. Do not rinse PVC or plastic items with pesticide grade isopropanol. 5. Rinse thoroughly with organic/analyte free water. 6. Remove the equipment from the decontamination area and cover with plastic. Equipment stored overnight will be covered and sealed with clean, unused plastic.

Wash with a high-pressure [2,500 pounds per square inch (psi) and 200 °F plus] steam cleaner with phosphate-free laboratory grade detergent (such as Liquinox® and potable water. Drilling equipment should be placed on racks or saw horses at least two feet above the floor of the decontamination pad. Hollow-stem augers, drill rods, etc., that are hollow or have halves that transmit water or drilling fluids, should be cleaned on the inside with vigorous brushing. 2. Rinse thoroughly high-pressure steam cleaner using potable water. 3. If oil or grease is observed, rinse with pesticide-grade isopropanol. 4. Rinse thoroughly with organic/analyte free water. Final decontamination ofall equipment used to complete the sampling effort will be required prior to equipment demobilization from the site. This decontamination step is required to prevent contaminants from being transported offsite by subcontractors' vehicles. Final decontamination will be performed at the decontamination area and will be witnessed by field personnel. The procedures used for decontamination between sampling locations will be utilized during final decontamination.

All the groundwater samples to be collected at the Site as described in Section 3.0 of this FSP are to be analyzed by one or more of the following CLP analytical methods: SOMO!. I ( volatile organics; semivolatile organics; and pesticides/PCBs); and rLM05.3 (metals and cyanide) (EPA, 2004c; EPA, 2006c). The proper containers, preservation methods, and holding times established for the analytical methods to be used for the site soil and water samples are presented in Table 6-1. 6.2 Sample Collection Documentation Sample collection documentation procedures are another vital aspect of any environmental sampling event. Each sample or field measurement must be properly documented to facilitate timely, correct, and complete analysis. Additionally, sample custody procedures are necessary-to support the use of data in potential enforcement actions at a site. 6.2.1 Field Operation Records The most important aspect of sample collection documentation is thorough, accurate recordkeeping. The documentation of field operations associated with sample collection will be recorded on Groundwater Sample Collection Records, field logbooks, and photodocumentation logs. Information required on Groundwater Sample Collection Records and field logbooks, is discussed in Section 3.6 of the QAPP. Information to be included in photodocumentation logs is discussed below. Sample collection or other sample associated documentation may also take the form of photographs which will be organized into a photodocumentation log. The photographs may show the surrounding area and reference objects that identify the sampling locations. The film roll number will be iden_tified by photographing an informational sign on the first frame of the roll. This sign will show the site name, initials of photographer, film roll number, and date to identify the pictures contained on the roll. • i Field Sampling Plan EPA Contract No. 68-W-99-043 Work Assignment No. 693-RICO-A44F Sigmon's Septic Tank Site For example: Sigmon's Septic Tank (Sequence 2) Site Rl/FS, JPS, Roll I January 29, 2007 Section: 6 Revision No.: 0 December 14, 2006 Page 2 of3 An entry will be made in the field log identifying which sampling location is depicted in each photograph. · Logbook entries of photographs will have four major components: photographer's initials, roll number and frame number, date and a description of what was photographed. For example: JPS, 1-1, 01-03-01, Sampling at Well SS-MW-02A. Photographs will be attached to a photographic documentation form sheet that will contain the following information: Sheet No. Film No. (Roll No.) Site Name and Location Date Photograph Was Taken Day of the Week Photograph Was Taken Direction the Photographer Was Pointing the Camera Objects of Importance in Photograph (Sampling Location Identification) Roll No./Frame No. Photographic documentation form sheets may contain one or more photographs per page. 6.2.2 Sample Custody Documentation The sample chain-of-custody procedure provides another means of sample collection documentation. The sample chain-of-custody procedure documents the identifying, tracking, and monitoring of each sample from the point of collection through final data reporting. Sample labels, custody seals, EPA Organic or Inorganic Traffic Report and Chain-of- Custody Records (for CLP analysis), EPA Generic Traffic Report and Chain-of-Custody Records (for other than CLP analysis), and airbill numbers are used to maintain sample custody from collection through shipping to the analytical laboratory.

Types of !OW anticipated to be generated at the Sigmon's Septic Tank Site include: I) personal decontamination stations liquids; 2) well development and purge water; 3) personal protective equipment (PPE); 4) decontamination fluids; 5) drill cuttings from well installation; and 6) uncontaminated wastes. These types of IDW are the only forms of contaminants or pollutants anticipated to be generated as a result of RI/FS activities. Therefore, the procedures and safeguards listed below for each of the types of IDW . anticipated to be generated at the site will serve as the pollution control and mitigation plan for the site. The types ofIDW that are anticipated to be produced during the field operations at site and the procedures and safeguards for processing those wastes include the following: • Personal Decontamination Station Liquids. These liquids include the wash water from the boot wash and the hand and face wash containers. Contaminants typically found in these liquids result from activities which bring personnel in contact with the soil. The water will be placed in DOT- approved 55-gallon UN IA-I or IA-2 drums, labeled to indicate contents, and staged at a predetermined accumulation area on site. • • • Drill Cuttings. These materials are generated during the drilling ofboreholes . The procedure for handling the drill cuttings will be: I) to containerize the cuttings separately from each borehole in DOT-approved 55-gallon UN I A-1 or IA-2 drums; 2) label to indicate contents; 3) stage the drums at a designated onsite accumulation area; and 4) include drilling fluids with drill cuttings if drilling fluids are used. Well Development and Purge Water. These fluids include the groundwater obtained from monitoring well presampling development and purging activities. The water will be placed in DOT-approved 55-gallon UN I A-1 or IA-2 drums, labeled to indicate contents, and staged at a predetermined accumulation area on site. PPE. This category includes the disposable work clothing such as booties, gloves, and coveralls, worn by field personnel during the field investigation. The procedure for handling disposable personal protective clothing will be: I) place such articles in DOT-approved 55-gallon UN I A-1 or I A-2 drums; Field Sampling Plan EPA Contract No. 68-W-99-043 Section: 7 Revision No.: 0 December 14, 2006 Page 2 of2 Work Assignment No. 0029-RICO-A44F Sigmon's Septic Tank Site • • 2) label to indicate contents; and 3) stage on site at a designated onsite accumulation area. Decontamination Fluids. These fluids include wash waters used to decontaminate the sampling equipment as well as the PPE decontamination fluids. The water will be placed in DOT-approved 55-gallon UN IA-I or IA- 2 drums, labeled to indicate contents, and staged at a predetermined accumulation area on site. Uncontaminated Wastes. Packaging, household trash, flagging, etc., will be placed in trash sacks and removed from the site periodically by the contractor field team at the completion of field work. Drums containing cuttings, waste fluids, and personal protective clothing will be staged at the designated accumulation area on site during the field investigation and placed on pallets. The drums will be removed from each monitoring well location upon completion of well development at each location. Additional drum utilized during monitoring well sampling will be removed upon completion of the groundwater sampling effort. The final disposition of the drummed wastes will depend upon the field sample analytical results as supplemented by analyses of drum contents if needed.
