Site Site Description and History Investigation and Sampling Results Corrective Action and Current Status Public Health Evaluation
IRP site 1 Waste Disposal Area A One-acre inactive unit located east of the Virginia Electric and Power Company right-of-way and west of rail tracks. Wetlands are adjacent to the site. Landfill was used from 1921 - 1924, mainly for disposal of trash and garbage. Some pesticides, acids, and bases were dumped at the site (LANTDIV 2000b). The estimated volume of trash at this site is 30,000 cubic yards. According to site reports, trash was burned at site and the marsh area adjacent to Blows Creek was filled with ashes from those burning operations (LANTDIV 2000b). Some surface run-off from this site flows to Blows Creek (LANTDIV 2002).

The Navy sampled ambient air near this site for VOCs and radiation, in 1983. No significant signs of contamination were observed, and no further sampling was conducted at that time (LANTDIV 1996). The Navy sampled soil and groundwater for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives, in 1996, and found DDT, DDE, PAHs in soil and nitrobenzene in groundwater (LANTDIV 2000b).

Soil: One SVOC was detected above its CV, benzo(a)pyrene (0.370J ppm). Inorganics detected above CVs include arsenic (4.7 ppm), calcium (1,130 ppm), magnesium (913B ppm), potassium (824B ppm), and sodium (140B ppm) (LANTDIV 1996).

Shallow Groundwater: One VOC was detected above its CV, methylene chloride (16B ppb). Inorganics detected above CVs include arsenic (2.5B ppb), calcium (5,200 ppb), magnesium (5,890 ppb), potassium (4,520B ppb), and sodium (68,100 ppb) (LANTDIV 1996).

Soil was excavated from four test pits, tested, and then returned to the pits. A No Further Action consensus was reached in November 2002 based on sampling data and September 2002 test pit information (LANTDIV 2002). The surface of the site was smoothed and grass was planted (LANTDIV 2003c).

This IRP site does not currently pose any health hazards to the local community. There is currently no access to the base. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with soil is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.

Past burning operations (1921 - 1924) may have generated air emissions that could have blown to nearby residential areas.

IRP site 2 Waste Disposal Area B Inactive unit located in the southwestern section of the site, at the corner of St. Juliens Drive and Cradock Street. Wetlands are adjacent to the site; part of the landfill itself is a tidal wetland area (LANTDIV 2003b). Unlined landfill, used from 1921-1947, mainly used for garbage, acids, and waste ordnance (LANTDIV 2000b). The total area of the landfill was estimated to be 18,750 square feet (EPA 1999a). Blast grit from ship overhaul and repair operations were dumped at this site, though exact year is unknown. From 19421947, the Navy operated an incinerator here (LANTDIV 1981). Total pre-burning volume was approximately 950,000 cubic feet, half of it disposed of prior to 1942 (LANTDIV 2000b). Refuse was burned onsite and ash filled in adjacent swampy area.

The Navy sampled ambient air near this site for VOCs and radiation, in 1983. No significant signs of contamination were observed, and no further sampling was conducted at that time (LANTDIV 1996). At that time, the Navy noted a faint hydrocarbon odor emanating from the ground and several abandoned motor vehicles, however no samples were collected (LANTDIV 2000b). The Navy sampled soil and groundwater, in 1996 and 1998, for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives, and found PCB and pesticides in the soil, and acetone and the explosives TNT and TNB, in groundwater. EPA sampled soil, groundwater, sediment, and surface water, for VOCs, SVOCs, pesticides/PCBs, and inorganics, in 1997 (EPA 1999a).

Soil: One SVOC was above its CV, benzo(g,h,i)perylene (0.040J ppm). Inorganics detected above CVs include arsenic (3.8 ppm), calcium (8,650 ppm), chromium (225 ppm), copper (3,450 ppm), lead (1,830 ppm), magnesium (2,300 ppm), potassium (2,370 ppm), and sodium (494B ppm) (LANTDIV 1996).

Shallow Groundwater: Inorganics detected above CVs include arsenic (5.8B ppb), calcium (141,000 ppb), iron (18,900 ppb), magnesium (47,700 ppb), manganese (726 ppb), potassium (19,900 ppb), and sodium (215,000 ppb) (LANTDIV 1996).

Remedial investigation recommended further background sampling and additional surface water and groundwater sampling (LANTDIV 1998a).

This IRP site does not currently pose any health hazards to the local community. There is currently no access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with soil is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.

Past burning operations may have generated air emissions that could have blown to nearby residential areas.

IRP site 3 Waste Disposal Area C Inactive unit. This unlined landfill used from 1940-1970, covers 10 acres along northern edge of St. Juliens Creek Annex (LANTDIV 2000b). Wetlands are adjacent to this site. The original land was a mudflat, and it may have been a wetland area. The size of this area is not known (EPA 1999a). The landfill refuse includes solvents, acids, bases, and municipal waste (LANTDIV 2000b). Refuse was burned here starting around 1940 and continuing until about 1970 (LANTDIV 1981). The total volume of TCE, waste oil, and oil sludge buried here was estimated to be 750,000 cubic feet (LANTDIV 2000b), including around 11,500 cubic yards per year of trash and semi-wet trash between 1963 and 1966; oil was burned occasionally (LANTDIV 1981). Two pits at this site were used for oils and oily sludge and for periodic burning (LANTDIV 2000b).

The Navy sampled ambient air near this site for VOCs and radiation, in 1983. No significant signs of contamination were observed, and no further sampling was conducted at that time (LANTDIV 1996). The Navy sampled soil and groundwater, in 1996 and 1998, for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives, and found pesticides, PCB and PAHs in the soil and dinitrotoluene, trinitrobenzene, and nitrobenzene in the groundwater (LANTDIV 2000b). EPA sampled sediment for VOCs, SVOCs, pesticides/PCBs, and inorganics, in 1997 (EPA 1999a). The oil and sludge pits have not been sampled.

Soil: One VOC was detected above CVs, methyl chloride (0.004J ppm).

Surface Water: Inorganics detected above CVs include aluminum (70,600K ppb), arsenic (7.7J ppb), beryllium (22.6 ppb), cadmium (8.4 ppb), calcium (405,000 ppb), cobalt (255 ppb), iron (66,900 ppb), lead (27.8J ppb), magnesium (173,000 ppb), manganese (6,330 ppb), nickel (364 ppb), potassium (53,600J ppb), and sodium (514,000 ppb) (LANTDIV 2003b).

Remedial investigation recommended further background sampling and additional surface water sampling (LANTDIV 1998b). Soil was removed in September 2002. Clean soil was filled in and the site was planted with grass (LANTDIV 2003c). Phase I removal activity was considered to remediate the northern portion of Site 3. After Phase II removal action has been conducted in 2003, the Navy will evaluate the confirmation data to determine whether cleanup goals have been reached (LANTDIV 2003a).

This IRP site does not currently pose any health hazards to the local community. There is no public access to this site and the Navy has removed contaminated soil. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with soil is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.

Past burning operations between approximately 1940-1970 may have generated air emissions that could have blown to nearby residential areas.

IRP site 4 Landfill D Inactive unit located roughly 300 feet south of IRP site 3. Covers an estimated 5 acres. Wetlands are adjacent to this site. Unlined trench-and-fill landfill was used from approximately 1970 to 1981 (LANTDIV 2000b). The first trench is approximately 1,000 feet long and is located parallel to and 500 feet north of Blows Creek (LANTDIV 2000b). Soil from subsequent trenches was used to cover the previous trenches. According to personnel at the public works department, fluorescent light ballasts containing PCBs were disposed of at this landfill (EPA 1999a). The total number of trenches dug at landfill is unknown. Refuse at the site includes drums of unknown waste and PCBs. A dumpster labeled "Asbestos Only" was observed here. Previous reports indicate that several tanks of undetermined wastes were once located at this site (LANTDIV 2000b). The total volume of disposal is unknown (LANTDIV 2000b).

The Navy sampled ambient air near this site for VOCs and radiation, in 1983. No significant signs of contamination were observed, and no further sampling was conducted at that time (LANTDIV 1996). The Navy sampled soil and groundwater, in 1996 and 1998, for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives (LANTDIV 2000b). EPA sampled sediment for VOCs, SVOCs, pesticides/PCBs, and inorganics, in 1997 (EPA 1999a).

The SWMU was recommended for No Further Action in the RFA, with consensus for NFA in September 2002 (NEHC 2003b). The site is still under CERCLA investigation. The Navy, EPA, and VDEQ are considering a presumptive remedy consisting of a 2-foot soil cover (minimum). This will be addressed in a Feasibility Study for this site (LANTDIV 2003b).

This site does not currently pose any health hazards to the local community. There is currently no access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited soil contact is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.

Burning operations may have generated air emissions that could have blown to nearby residential areas.

IRP site 5 Burning Grounds Inactive unit, operated from the 1930s until the 1970s. The size of this area was estimated to be 22,525 square feet (EPA 1999a). It is located off of Cradock St. in the northern part of site. Currently, site consists of an open field with areas that are overgrown with reeds; there are wetlands to the east and west of this site. In 1977 the area was burned using oil and straw, cut up, and burned again, in an effort to decontaminate soil. Waste ordnance materials burned here included black powder, smokeless powder, explosive D, Composition A-3, tetryl, TNT, and fuses. Some non-ordnance materials burned here included carbon tetrachloride, trichloroethylene (TCE), paint sludges, pesticides, and various refuse (LANTDIV 2000b).

The Navy sampled soil and groundwater, in 1996 and 1998, for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives, and found pesticides, PAHs, di-n-butylphthatlate and DNT in the soil and inorganics in the groundwater (LANTDIV 2000b). EPA sampled sediment for VOCs, SVOCs, pesticides/PCBs, and inorganics, in 1997 (EPA 1999a).

Soil: One VOC was detected above its CV, methyl chloride (5J ppm). SVOCs over CVs include acenaphthylene (0.31J ppm), benzo(a)pyrene (1.2J ppm), benzo(g,h,i)perylene (0.96J ppm), and phenanthrene (0.34J ppm).

The Navy, EPA, and VDEQ are considering a presumptive remedy consisting of a soil cover and/or removal of waste, soil, and sediment that poses potential risks. This will be addressed in the Feasibility Study for this site (LANTDIV 2003b).

This IRP site does not currently pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited soil contact is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.

Burning operations may have generated air emissions that could have blown to nearby residential areas.

IRP site 6 Small Items Pit (Caged Pit) Inactive unit located east of Site 5 and investigated as part of Site 5. The caged pit was used to burn small arms (including igniters and fuses). The dimensions of the cage are not known. There is no surface evidence of this pit at the site currently. There is a small ditch on the east side of this site (LANTDIV 2000b).

The Navy sampled soil, in 1996, for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives, and found DDT, DDE, PAHs in soil. Groundwater was not sampled (LANTDIV 2000b).

Soil: One SVOC was detected above its CV, benzo(a)pyrene (0.91 ppm). Inorganics detected above CVs include arsenic (4.6 ppm), calcium (19,500 ppm), magnesium (716B ppm), potassium (581B ppm), and sodium (113 ppm) (LANTDIV 1996).

Site 6 was removed in the summer of 2002 (LANTDIV 2003b). As a result of removal actions, the potential exposure to contaminated soil at this site has been eliminated (EPA 2003). The Navy has recommended No Further Action (NFA) at this site (LANTDIV 2003a). The NFA ROD should be signed during 2003 (NEHC 2003b).

This IRP site is not a health hazards to the local community. There is no public access and the Navy removed contaminated soil. On-base residents may have had access to this site, but incidental exposures are not expected to affect health.

Burning operations may have generated emissions that could have blown to nearby residential areas.

IRP site 7 Old Storage Yard Inactive unit. The storage yard is a fenced, grassy outdoor area, located near the middle of the site. The dimensions and the years of operation of the yard are not known. It is used to store a variety of materials including anchors, chain, scrap metal, obsolete equipment, and salvaged material (LANTDIV 2000b; EPA 1999a).

Past investigations found 5-gallon hydraulic oil containers, lubricating oil, lead paint, and evidence that oils had leaked or were drained onto soil from some equip stored at (LANTDIV 2000b). The Navy sampled soil, in 1996, for VOCs, SVOCs, pesticides/PCBs, and inorganics. Groundwater was not sampled (LANTDIV 2000b).

Soil: Inorganics detected above CVs include arsenic (2.6 ppm), calcium (2,260 ppm), magnesium (3,330 ppm), potassium (3,050 ppm), and sodium (172B ppm) (LANTDIV 1996).

Surface debris was removed from Site 7 in September 2002. The Navy, VDEQ, and EPA reached a consensus for No Further Action at this site in April 2002 (NEHC 2003b). This IRP site does not currently pose any health hazards to the local community. There is no public access to this site and the Navy has removed contaminated materials. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas.
IRP site 8 Cross and Mine Site Inactive unit, formerly used for disposal of rinse water from insecticide and herbicide spray trucks from the 1950s to mid-1960s. Located near the intersection of Cross St and Mine Rd, between two sets of railroad tracks, next to and north of Building 212 and across the street from Building M-1. The Navy discharged an estimated 675,000 gallons in this area (LANTDIV 2000b). There are no surface water drainages or other pathways by which site-related chemicals could be transported away from this site (LANTDIV 2002). The Navy sampled ambient air near this site for VOCs and radiation, in 1983. No significant signs of contamination were observed, and no further sampling was conducted at that time. The Navy sampled soil for VOCs and pesticides/PCBs, and groundwater for pesticides/PCBs, in 1996, and found DDT, DDD, DDE, and endrin. No contaminants were detected above CVs in soil or in groundwater (LANTDIV 1996). Recommended for further study based on site historical record of 675,000 gallons of pesticide rinse water that was discharged to the ground (LANTDIV 2002). This IRP site does not pose any health hazards to the local community. There is no public access to this site. Residents of St. Juliens Creek Annex may have had access to this site; however ATSDR expects that the exposures would have been infrequent and for short periods of time, and unlikely to result in health effects. ATSDR supports the Navy's plans for additional soil and groundwater testing to ensure that the area is adequately characterized.
IRP site 9 Pesticide Control Shop, Building 249 Inactive unit located under Building 1556, which was constructed in the mid1990s. The soil is paved over, and there is a storm ditch along the south side of the site (LANTDIV 2000b).

The Navy sampled ambient air near this site for VOCs and radiation, in 1983. No significant signs of contamination were observed (LANTDIV 1996). The Navy sampled soil and groundwater for VOCs, SVOCs, pesticides/PCBs, and inorganics, in 1991, prior to excavation at this site. The Navy sampled soil for VOCs, and groundwater for VOCs, SVOCs, pesticides/PCBs, and inorganics, in 1996 (LANTDIV 2000b). No contaminants were detected above CVs in soil testing conducted the excavation in 1991.

Soil: One SVOC was detected above CVs, phenanthrene (0.36J ppm). Inorganics detected above CVs include arsenic (111B ppm), cadmium (193* ppm), calcium (4,630* ppm), chromium (367N* ppm), lead (1,100 ppm), magnesium (1,290E ppb), potassium (696B ppm) and sodium (241BE ppm) (LANTDIV 2003b).

Shallow Groundwater: VOCs detected above CVs include 1,2-DCE (550D ppb), methylene chloride (380BDJ ppb), and trichloroethylene (5200D ppb). Inorganics detected above CVs include aluminum (60,500 ppb), antimony (47.7B ppb), arsenic (19.6N ppb), barium (232E ppb), beryllium (1 ppb), cadmium (3 ppb), calcium (36,800 ppb), chromium (96 ppb), cobalt (21B ppb), copper (15B ppb), iron (58,200 ppb), lead (152 ppb), magnesium (10,500 ppb), manganese (1,980 ppb), potassium (12,800E ppb), sodium (32,200 ppb), and vanadium (127 ppb) (LANTDIV 1996, 2003b).

No Further Action (NFA) will be taken at this site. EPA, VDEQ, and the Navy agreed in June 1999 that cleanup goals were met by the soil excavation and remediation associated with the construction of Building 1556 in this location (LANTDIV 2000b). This IRP site does not currently pose any health hazards to the local community. Cleanup efforts are complete. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with soil is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.
IRP site 10 Hazardous Waste Disposal Area at Railroad

Inactive unit located in the vicinity of Building 13. This site was a disposal location for wastes generated during hardware cleaning operations from before 1940 to the mid-1970s. The soil at this site has been paved over. Building 13 is a well-maintained machine shop with no evidence of contamination (LANTDIV 2000b).

Limited records indicate wastes dumped here included alodine (a caustic detergent), methylene chloride, and acetone. Liquid wastes were poured on tracks (LANTDIV 2000b).

The Navy did not observe any evidence of releases during Phase II investigation (LANTDIV 2000b). The Navy sampled soil and groundwater, in 1996, for inorganics, SVOCs, and VOCs, and found metals, PAHs, and methylene chloride in the soil, and TCE in one groundwater sample (LANTDIV 2000b).

Soil: One SVOC was detected above its CV, benzo(a)pyrene (0.52J ppm). Inorganics detected above CVs include arsenic (10.6 ppm), calcium (3,380 ppm), magnesium (1,480 ppm), potassium (434 ppm), and sodium (83.9B ppm) (LANTDIV 1996).

Recommended for No Further Action (NFA) in February 2002 (LANTDIV 2002). This IRP site does not currently pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with soils is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.
IRP site 11 Hazardous Waste Disposal Area at Building 53

Inactive unit located in the industrial area, east of Cradock Street. Building 53 was also called Building 266, it was the electrical shop (LANTDIV 2000b). There are no surface water drainages or other pathways by which site-related chemicals could be transported away from this site (LANTDIV 2002).

Electricians used 5 gallons of TCE per month. Most of the solvent evaporated, but the remainder was disposed on the railroad track bed adjacent to the building. As of 1989, the building had been converted to a recreation center (LANTDIV 2000b).

The Navy found no evidence of waste disposal near Building 53. The Navy sampled soil and groundwater, in 1996, for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives (groundwater only), and found DDT, DDE, other pesticides, and PAHs in the soil and TCE, DCE, and methylene chloride in the groundwater sample (LANTDIV 2000b).

Soil: One SVOC was detected above its CV, benzo(a)pyrene (0.57J ppm). Pesticides/PCBs detected above CVs include aroclor-1260 (6.1E ppm) and dieldrin (0.063 ppm). Inorganics detected above CVs include arsenic (3.3 ppm), calcium (1,040 ppm), lead (1,040 ppm), magnesium (507B ppm), potassium (410B ppm), and sodium (51.5B ppm) (LANTDIV 1996).

Shallow Groundwater: VOCs detected above CVs include 1,2-DCE (110 ppb), methylene chloride (11 ppb), and trichloroethylene (46 ppb) (LANTDIV 1996).

Recommended for No Further Action (NFA) in February 2002. The presence of VOCs in groundwater will be addressed under further investigation of groundwater at Site 21, which is near Site 11 (LANTDIV 2002). No soil response has been specified at this site. This IRP site does not currently pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with detected level of soil contamination is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.
IRP site 12 Sand Blast Area At Building 323 Inactive unit located under Building 1556, which was constructed in the mid1990s. The soil is paved over, and there is a storm ditch along the south side of the site (LANTDIV 2000b).

The Navy removed and disposed of the UST at this site, then excavated surrounding soil and backfilled the area (LANTDIV 2000d). Oversight of this unit is now managed by the RCRA UST program. This site is no longer part of the CERCLA process. Future actions have not been specified (LANTDIV 2000b). This IRP site does not currently pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with soils is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.
IRP site 16 Defense Reutilization Marketing Office (DRMO) Storage Yard Active Unit, near inactive tracks. This is a large fenced, mostly paved (or concrete) area located off Cradock St. There is a small storm water ditch on this site. Wastes noted at site during RCRA visit include scrap stainless steel. RCRA report states there was no evidence of hazardous materials being managed at the site (LANTDIV 2000b).

The Navy sampled soil and groundwater, in 1996, for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives (LANTDIV 2000b).

Soil: One SVOC was detected above its CV, benzo(a)pyrene (0.48J ppm). Pesticides/PCBs detected above CVs include aroclor-1254 (9.4D ppm) and dieldrin (0.063 ppm). Inorganics detected above CVs include arsenic (5.8 ppm), cadmium (38.1 ppm), calcium (5,970 ppm), copper (8,270 ppm), lead (713 ppm), magnesium (2,130 ppm), potassium (2,030 ppm), and sodium (72.8B ppm) (LANTDIV 1996).

The Navy has scheduled further investigation. Future actions have not been specified for this site (LANTDIV 2000b). This site is still active, but the DRMO does not fall under CERCLA; the Navy, VDEQ, and EPA reached an NFA consensus in July 2002 (NEHC 2003b). This IRP site does not currently pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with soil is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.
IRP site 17 AOC-A, Building 278 and Building 279, Storage Pad

Inactive unit. Used to store two 55-gallon drums of PD-860, a commercial degreaser (LANTDIV 2000b). Located south of Building 1556, at the upper reaches of the drainage channel that flows in to the marsh/ wetland area of Waste Disposal Area B, within industrial area and east of Cradock Street. There are wetlands alongside the northwest side of this site (LANTDIV 2000b).

The RCRA site visit found stains on the ground near the pad, and an overflowing catch bucket under a drum spigot (LANTDIV 2000b).

The Navy sampled soil and groundwater, in 1996, for VOCs, SVOCs, pesticides/PCBs, and inorganics, and found inorganics, DDT, DDE, DDD, alpha chlordane, aroclor-1254, dieldrin, endrin, PAHs, gamma chlordane, bis(2-ethylhexyl)phthalate in the soil and no organics in the groundwater samples (LANTDIV 2000b).

Soil: One SVOC was detected above its CV, benzo(a)pyrene (0.47J ppm). Inorganics detected above CVs include arsenic (2.4 ppm), calcium (2,340 ppm), magnesium (962 ppm), potassium (852B ppm), and sodium (57.1B ppm) (LANTDIV 1996).

The Navy recommended further sampling of contaminants in soil and groundwater (LANTDIV 2001). This IRP site does not currently pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with soils is not expected to have affected health. Groundwater beneath this site is not being used for drinking or other purposes.
IRP site 18 AOC-A, Building 47, Blasting Grit Inactive unit. Building 47 houses two sand blasting booths adjacent to the south wall of Building 47. The site is mostly paved-over. The 1999 site visit noted black blasting grit at site. Personnel in that building do not use black blasting grit in their machines, therefore the source is unknown (LANTDIV 2000b). There are no surface water drainages or other pathways which could transport chemical off of the site (LANTDIV 2002).

The Navy sampled soil, in 1996, for VOCs, SVOCs, and inorganics, and found elevated levels of metals and bis(2-ethylhexyl)phthalate, PAHs, phenol, carbazole, and TCE in soil. No groundwater samples were taken (LANTDIV 2000b).

Soil: One SVOC was detected above its CV, benzo(a)pyrene (0.47 ppm). Inorganics detected above CVs include arsenic (3.9 ppm), cadmium (32.2 ppm), calcium (754B ppm), lead (907 ppm), magnesium (394B ppm), potassium (309B ppm), and sodium (152B ppm). (LANTDIV 1996).

Consensus for No Further Action (NFA) in June 2002 (LANTDIV 2002). This IRP site does not currently pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact with low levels of substances detected in soils is not expected to have affected health.
IRP site 19
Wharf Area, Building M5
Inactive unit located between building M-5 and Building 190. There is a tidal marsh to the east side of this site. Ordnance items may have been dropped into the river sediments located near here during management activities. (LANTDIV 2000b). No ordnance has been found at this site (NEHC 2003b).

The Navy sampled soil and groundwater for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives, in 1996. Sampling found DDT, DDE, DDD, alpha chlordane, Aroclor-1254, dieldrin, endrin, and PAHs in the soil. The one groundwater sample contained acetone and methylene chloride (LANTDIV 2000b).

Soil: One SVOC was detected above its CV, benzo(a)pyrene (0.48J ppm). One pesticide/PCB was detected above its CV, dieldrin (0.055P ppm). Inorganics detected above CVs include antimony (120 ppm), arsenic (24.3 ppm), cadmium (396 ppm), calcium (774B ppm), chromium (1,040 ppm), copper (42,500 ppm), lead (6,200 ppm), magnesium (550B ppm), potassium (354B ppm), and sodium (21.4B ppm) (LANTDIV 1996).

Shallow Groundwater: One VOC was detected above its CV, methylene chloride (11 ppb). Inorganics detected above CVs include arsenic (12 ppb), calcium (9,640 ppb), lead (15.3 ppb), magnesium (30,400 ppb), potassium (12,800 ppb), sodium (16,400 ppb), and vanadium (42.7B ppb) (LANTDIV 1996).

Recommended for further study to confirm the presence of arsenic and methylene chloride in the groundwater, and to address contaminants found in surface soil (LANTDIV 2002). This IRP site does not currently pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact to soils at detected levels is not be expected to have affected health. Groundwater beneath this site is not used for drinking or other purposes.
IRP site 20
Wharf Area Sediments
Inactive unit located adjacent to the former wharf. Loading and unloading operations may have dropped munitions and unexploded ordnance here, in the area of the former pier and in the area of the current pier (LANTDIV 1981). There is a fence between the wharf area and the site lands.

A magnetometer survey conducted by the Navy found 68 buried contacts surrounding the former wharf pilings, many in random locations between pilings, particularly along the center west side of the pilings, between the river bank and the pilings. Contacts do not necessarily indicate the presence of buried ordnance. Divers identified some metal and deep silt in the area of the old pier. No visual confirmation of the contacts were made during the data collection study (LANTDIV 2000b). The Navy sampled sediment for VOCs, SVOCs, pesticides/PCBs, inorganics, and explosives, in 1996. No explosive constituents were detected.

Sediment: One SVOC was detected above its CV, benzo(a)pyrene (0.68J ppm). Inorganics detected above CV include arsenic (2.4 ppm), calcium (967B ppm), magnesium (1,190 ppm), potassium (1,000B ppm), and sodium (1,820 ppm) (LANTDIV 1996).

Recommended for No Further Action (NFA) under CERCLA in February 2002. The Navy Range Program will post signs to indicate potential UXO in sediments and to prevent intrusive activities. LANTDIV Real Estate documents will be annotated to reflect this situation, and a notice will be sent to USACE to prevent dredging without proper UXO clearance (LANTDIV 2002). Local residents that use the Elizabeth River for recreational purposes (swimming, boating, fishing) are expected to contact sediments only incidentally. However, boats that attempt to land at the shore or drop anchors near the wharf area or near the former pier area may be at risk from unexploded ordnance. This site is considered a physical hazard; however recreational users can protect themselves by following the warming signs posted by the Navy Range Program.
IRP site 21 Building 187 Soil Staining Inactive unit, formerly used as a locomotive shed and for locomotive maintenance. The soil at this site is mostly paved over. The area around the locomotive shed is saturated with oil (LANTDIV 2000b). There are no surface water drainages or other pathways by which site-related chemicals could be transported away from this site, and there are no known discharge points for groundwater (LANTDIV 2002).

The Navy sampled soil and groundwater, in 1996, for VOCs, SVOCs, pesticides/PCBs, and inorganics (LANTDIV 2000b). The soil sampling appears to have been conducted outside of the oil-saturated area around the shed.

Soil: Inorganics detected above CV include arsenic (2.6 ppm), calcium (7,660 ppm), magnesium (3,040 ppm), potassium (1,520 ppm), and sodium (67.4B ppm) (LANTDIV 1996).

Shallow Groundwater: VOCs detected above CV include methylene chloride (160BDJ ppb) and trichloroethylene (2400B ppb). Inorganics detected above CV include arsenic (2.4B ppb), calcium (5,880 ppb), magnesium (4,280B ppb), manganese (602 ppb), potassium (1,920B ppb), and sodium (21,600 ppb) (LANTDIV 1996).

Recommended for further study based on the maximum contaminant level exceedences of VOCs in groundwater (LANTDIV 2002). This IRP site does not currently pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact to the low levels of contamination detected is not expected to have affected health. Groundwater beneath the site is not used for drinking or other purposes.
EPIC AOC 1 E Street and Marsh Road Ground Scarring, Northernmost area of annex Inactive unit located at the corner of E Street and Marsh Road (LANTDIV 2000b). Marine shell fragments were observed in the soil during a site visit, indicating that this area may have been filled with dredge fill. This site is located near Blows Creek and site-related contaminants, if any, could be transported to Blows Creek via surface run-off (LANTDIV 2002).

The EPIC study identified this as a possible waste disposal area, based on aerial photos from 1937. 1949 aerial photos show that buildings 181 and 182 were built to the north of, and directly on top of, this area (LANTDIV 2000b). The Navy tested soil at this area for inorganics, pesticides/PCBs, SVOCs, and VOCs, in 2001.

Soil: SVOCs detected above CVs include benzo(a)anthracene (15,000 ppb), benzo(a)pyrene (11,000 ppb), benzo(b)fluoranthene (12,000 ppb), and dibenz(a,h)anthracene (1,500 ppb) (LANTDIV 2002).

Recommended for further study based on analysis of site data that suggested further consideration was needed to address elevated PAH levels in surface soil (LANTDIV 2002). This site does not pose any health hazards to the local community. There is no public access to this site. ATSDR expects that residents of on-site housing areas had little or no access to industrial areas (before the Navy closed the housing areas), and limited contact to the contaminants detected in the soil is not expected to have affected health.
EPIC AOC 2 Piers in front of Building 83 Inactive unit, formerly used as a storage area. Unit is located at the piers in front of Building 83 (LANTDIV 2000b). The EPIC study identified this as a possible storage site for ordnance materials, based on aerial photos from 1974 (LANTDIV 2000b). No chemical releases have been reported from this area (LANTDIV 2002). The Navy, VDEQ, and EPA reached consensus on No Further Action (NFA) in June 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 3 Ground Scarring at Building M5 Inactive unit located to the east of Building M-5 (LANTDIV 2000b). The EPIC study identified a 70-foot-diameter circular area with many areas of ground scarring, near building M-5, based on aerial photos from 1949 (LANTDIV 2000b). Observations made during the November 1999 site visit suggest that ground scarring observed in aerial photographs resulted from fill material, not from chemicals in the soil (LANTDIV 2002). The Navy, VDEQ, and EPA reached consensus on No Further Action (NFA) in June 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 4 Parking Area South of Building M1 Inactive unit located in the parking area to the south of Building M-1 (LANTDIV 2000b). The EPIC study identified an area of soil staining based on aerial photos from May 1958 (LANTDIV 2000b). Additional review of aerial photographs suggested that the "tanks" that had been identified in earlier photos were trailers, and that observed soil staining may have resulted from parked cars (LANTDIV 2002). The Navy, VDEQ, and EPA reached consensus on No Further Action (NFA) in June 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 5 Possible Soil Staining Between Buildings 87, 88 Inactive unit located between buildings 87 and 88 (LANTDIV 2000b). The EPIC study identified possible soil staining, based on aerial photos from April 1949 (LANTDIV 2000b). Observations made during the site visit in November 1999 suggest that the identified staining was likely the result of standing water or wet soil with poor drainage (LANTDIV 2002). The Navy, VDEQ, and EPA reached consensus on No Further Action (NFA) in June 2002 Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 6 Ground Scarring East of Site 2 Inactive unit located across from Waste Disposal Area B, and south of Building 1555 (LANTDIV 2000b). The EPIC study identified ground scarring and possible waste disposal, based on aerial photos from October 1964 (LANTDIV 2000b). Based on a reevaluation of this area, the apparent "ground scarring" was caused by construction of high voltage transmission towers (LANTDIV 2002). The Navy, VDEQ, and EPA reached consensus on No Further Action (NFA) in June 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 7 City of Portsmouth Outgrant Area Inactive unit located in the city of Portsmouth, outgrant area, south of ball fields and west of creek (LANTDIV 2000b). The EPIC study identified a ground disturbance, scarring, and mounded material, based on aerial photos from October 1974 (LANTDIV 2000b). There is no history of disposal of hazardous materials here, nor any storage or operations that involve hazardous materials; the identified ground disturbance is assumed to have been from filling the area with soil (LANTDIV 2002). The Navy, VDEQ, and EPA reached consensus on No Further Action (NFA) in June 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 8 Possible waste Disposal, Northeast and adjacent to Building 176 Inactive unit. This is a flat area that is maintained as a grassy field, approximately 300 feet long and 60 feet wide and located to the northeast of Building 176, southeast of EPIC AOC 1 (LANTDIV 2000b). The EPIC study identified a possible waste disposal area, bulk material, and storage, based on aerial photos from October 1974 (LANTDIV 2000b). A geophysical survey identified three anomalies: one appeared to be caused by above-ground features such as fences and metal structures, and the other two by small buried man-made objects (LANTDIV 2002). The Navy, VDEQ, and EPA reached consensus on No Further Action (NFA) in June 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 9 Ground scarring southwest of Building 74 Inactive unit located to the southwest of Building 74 (LANTDIV 2000b). The EPIC study identified a 40-foot-square area of ground scarring, based on aerial photos from October 1974 and then also seen in photos from the early 1970s and early 1980s (LANTDIV 2000b). Further review of photographs, and evaluation of current past site conditions, suggested that the "ground scarring" appeared to be due to steam from overhead steam lines (LANTDIV 2002). The Navy, VDEQ, and EPA reached consensus on No Further Action (NFA) in June 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 10 Ground scarring in wharf area Inactive unit located to the south of Building M-5 (LANTDIV 2000b). The EPIC study identified ground scarring along the wharf areas (believed to be from building demolition) based on aerial photos from June 1986. This is the former location of buildings 244, 245 and 256 (LANTDIV 2000b). The ground scarring may be associated with the demolition of those buildings (LANTDIV 2002). Recommended for No Further Action (NFA) in February 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 11 Open storage area northeast of Building 55 Inactive unit, formerly used as open storage, possibly open storage of drums. Located to the northeast of Building 55 (LANTDIV 2000b). The EPIC study identified possible open drum storage and material from Building 55, based on aerial photos from 1985 and 1986. There is evidence of storage in this area in previous and subsequent photos (LANTDIV 2000b). However, there is no evidence of a release of hazardous materials at this area (LANTDIV 2002). Recommended for No Further Action (NFA) in February 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
EPIC AOC 12 E Street and March Road Ground Scarring, North of Buildings M1 and M-5

Inactive unit. A sandy flat area without vegetation, and located north of buildings M-1 and M-5, directly adjacent to Blows Creek, near wetlands (LANTDIV 2000b). Surface run-off from this site may flow to Blows Creek (LANTDIV 2002).

Shell fragments found at the site confirm the area had been filled during the development of the area (LANTDIV 2000b).

The EPIC study identified an area devoid of vegetation, based on aerial photos, but the site appears to have been filled in during development (LANTDIV 2000b). A geophysical survey found four anomalies: one was likely due to partially-buried concrete blocks, two others likely caused by buried man-made objects, and the fourth due to the adjacent railroad tracks (LANTDIV 2002). Recommended for No Further Action (NFA) in February 2002. Further review of aerial photographs and historical site use, and a July 2001 site visit indicate this AOC is not a threat to human health or the environment (LANTDIV 2002). This site does not pose any health hazards to the local community. No evidence of chemical releases was found.
Petroleum contamination at Building 201 Inactive unit. A former pump island. Two 12,000-gallon USTs were located to the northwest of Building 201 (LANTDIV 1995). In 1990, LANTDIV sampled soil and groundwater, and found BTEX in soil up to 0.167 ppm, and BTEX in groundwater up to 0.007 ppm. In 1991, further sampling found background light-end petroleum hydrocarbons in soil and groundwater. In 1993, investigations found that soil gas was primarily found in areas local to the former pump island, and lead (0.481 ppm) was detected in groundwater. BTEX (5.21 ppm) was detected in soil gas beneath this site in 1993 (LANTDIV 1995). The corrective action plan recommended a groundwater depression system, in conjunction with manual bailing and a vapor extraction system as a remediation alternative (LANTDIV 1995). This site is not a health hazards to the local community. There is no public access to this site. On-base residents may have had access to this site, but exposures are not expected to affect health. Groundwater beneath this site is not used for drinking or other purposes.
Other Past Inhalation Exposure due to Operations at St. Juliens Creek Annex In addition to the burning of trash and ordnance, past operations at St. Juliens Creek Annex included metal plating; degreasing; painting; operation of hydraulic equipment, vehicles and locomotives; ordnance loading, testing, disassembly, and destruction; pest control; maintenance of lead-acid batteries; and printing. ATSDR was unable to identify any permits for air releases held by St. Juliens Creek Annex. No past air sampling data have been identified. The past sources of air emissions are no longer active. While the actual exposure to the chemicals released to the air by these operations is indeterminate; it is unlikely that they would have generated air emissions at a level that could have affected the health of either the on-base or off-base residential communities.
