Site Description

HQ 10th MTN Division & Fort Drum facility is located at Jones Street and Off North Memorial Drive, in Fort Drum, in the northern portion of New York State approximately 10 miles northeast of Watertown. Fort Drum is the largest Army installation in the northeast, covering about 107,265 acres.

The facility has twenty solid waste management units and seven areas of concern undergoing corrective action, including nine landfills, seven underground storage tank sites, four storage areas, four spill sites, and three explosive ordnance disposal areas.

Beginning in 1980, Ft. Drum conducted investigations and implemented interim corrective actions to evaluate and mitigate releases to the environment. The corrective action program is the responsibility of the US Department of Defense and the Army Corps of Engineers, and it is monitored by New York State Department of Environmental Conservation (NYSDEC) under the Resource Conservation and Recovery Act (RCRA) program.

Site Responsibility and Legal Instrument

The Facility has RCRA interim status. A New York State consent order is being negotiated to ensure implementation of the final remedial measures.

Permit Status

Fort Drum withdrew its Part B RCRA permit application and closed the interim status container storage facility in July 2000. Currently, corrective action is being performed on a voluntary basis until NYSDEC issue an Order on Consent

Potential Threats and Contaminants

Past solid waste disposal practices have resulted in the contamination of soil, groundwater, surface water and sediment of waterways which flow through the facility. The primary sources of contamination are the leaking underground storage tanks which resulted in free product floating on the water table. Other sources of contamination are as follows:

Contamination is primarily on-site, but until recently a groundwater plume consisting of gasoline with methyl tertiary butyl ether (MTBE) extended approximately 800 feet from its origin to the facility boundary including about 50 feet off-site. This plume originated from Building 2140, a former gas station located in the southwest portion of the site near the Black River.

The following three fate and transport pathways were evaluated at Fort Drum:

All potential exposure pathways were also evaluated such as on-site workers, trespassers, construction workers, and military personnel who may potentially be exposed to inhalation, ingestion and dermal contact. A risk estimate was calculated for this site using maximum exposure point concentrations. The result of the estimated calculations show that cumulative risks are within EPA's risk range (10-4 to 10-6) for carcinogens, and below the hazard index of 1.0 for non-carcinogens.

With respect to the landfill seepage to the unnamed creek, dilution of contaminants in the creek occurs rapidly and does not pose an unacceptable risk to downstream recreational activities. That conclusion is supported by results of quarterly sampling performed in the creek. However, there is a potential for contaminant exposure to ecological receptors in the area surrounding the site if the landfill-seepage concentration increases. All personnel working on site (construction and on site workers) follow the appropriate health and safety requirements to eliminate exposure. Trespassers are not anticipated to be exposed to contaminated areas at this facility as access is controlled.

Cleanup Approach and Progress

Fort Drum is implementing Interim Corrective Measures (ICMs), which consist of direct contaminant source removal, groundwater pump and treatment and free oil recovery operations. Approximately 12,000 tons of contaminated soils, 32,500 gallons of free product and 110 million gallons of groundwater have been removed, treated and disposed of as part of the interim measures to date. Ft. Drum is currently conducting an ICM consisting of bioventing and aquifer air sparging in Areas 1395 and 1495 of Gasoline Alley. In addition, Ft. Drum is currently conducting a phytoremediation pilot study, via construction of a wetland, to address impacted surface water from the Old Sanitary Landfill.

The Interim Corrective Measures already implemented include: the Removal of 22 underground storage tanks and contaminated soil along Gasoline Alley; debris removal and composite capping at two landfills; installation and operation of six free product and groundwater recovery systems; installation and operation of two bioventing systems and; demolition and soil removal to address pesticide and herbicide contamination.

The two areas with potential off-site groundwater migration, Area 2140 and Area 1795/World War II Landfill, have been addressed. Offsite migration near Area 2140 is currently being contained by the operation of five extraction wells to collect free product and groundwater as well as five air sparging wells with ozone injection to collect contaminated groundwater at the border. A remedial action approved on March 20, 2007 is also operating near Area 1795 (Gasoline Alley Area), which consists in a combination of Air Sparging and Soil Vapor Extraction, and recent data show that off-site groundwater is under control (below New York State groundwater standards). The remediation for Area 2140 at the property line is working as designed, and to prevent contamination downgradient Ft. Drum has installed two additional aquifer air sparging/bioventing units.

With the successful operation of five extraction wells to collect free product and groundwater as well as five air sparging wells with ozone injection to collect contaminated groundwater at the border, offsite groundwater migration near Area 2140 is under control.

The following is a summary of remedial work that still needs to be completed:
