Response Complete

We haven't independently confirmed the location of every site. If you notice a site placed at the incorrect location, please contact us.

Not all sites in the DOD data include location information, so there may be sites listed below that are missing from the map. The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.

38 Active Sites

Sites where military cleanup actions are still ongoing. The risk level of a site refers to a relative risk assessment made by the DOD, which prioritizes the cleanup of sites that pose greatest threat to safety, human health, and the environment.

Contaminated Areas

Groundwater: High Risk

Contaminants are present in the groundwater, which is very shallow (less than 2 feet deep). Groundwater plume extends more than 200 feet off site toward the northwest. Human receptors are possible with usage of shallow wells for lawn care, car washing. Human and waterfowl, aquatic life exposure in surface water in wetlands adjacent to site is unlikely but possible, due to very shallow groundwater table.

Contaminants: Benzene 18.0 ug/L 1,1-Dichloroethylene 29.0 ug/L Vinyl Chloride 41.0 ug/L Tetrachloroethylene 87.0 ug/L 1,2-Dichloroethylene (trans) 120.0 ug/L Naphthalene 560.0 ug/L 1,4-Dichlorobenzene 740.0 ug/L Trichloroethylene (TCE) 6400.0 ug/L 1,2-Dichloroethylene (cis) 14000.0 ug/L

Surface Water (Fresh): Medium Risk

Groundwater may recharge surface water. Animals may drink the surface water.

Contaminants: Trichloroethylene (TCE) 1.0 ug/L PCB 5.0 ug/L

Surface Water: Low Risk

Groundwater may recharge surface water. Several site control procedures will be implemented to reduce worker and public exposure to chemical, physical, biological, and safety hazards.

Contaminants: Trichloroethylene (TCE) 1.0 ug/L PCB 5.0 ug/L

Contaminated Areas

Groundwater: Medium Risk

Floating product was detected in one of the wells at the site. Groundwater contaminants at the site consist of dissolved fuel constituents. Although a drinking water well exists at the site, it is installed in a deeper formation than the shallow petroleum contamination.

Contaminants: Benzene 50.0 ug/L Toluene 1000.0 ug/L Ethyl benzene 2500.0 ug/L

Soil: Low Risk

Soils have been noted with saturated petroleum product near former fuel lines and tanks. Petroleum has migrated through soils and along backfill for piping at site. Although a drinking water well exists at the site, it is installed in a deeper formation than the shallow petroleum contamination.

Contaminants: Ethenylbenzene 0.03 mg/kg Toluene 0.03 mg/kg Benzene 0.05 mg/kg

Evidence (i.e., no controls to limit migration) indicates the lead contamination could move from the MRA boundaries. Significant evidence indicates the lead contamination has been moving along water channels within the MRA. This also allows any PAH contam Humans and ecological receptors have complete access to the contamination when in the MRA. . This MRA lies within the flightline security fence, limiting exposure of human receptors.

Contaminated Areas

Groundwater: Low Risk

Groundwater plume has not migrated since 1997 sampling. Most downgradient well results are 0.16 ug/L for napthalene (MW-12) in Mar 1999 sampling. Receptors would be limited to workers conducting excavation at source area. Groundwater does not discharge to sensitive area near site. However, vapors have been reported in the past in the housing. Following bioventing, this problem has ceased.

Contaminated Areas

Groundwater: Medium Risk

Metals on the site may leach into groundwater, as groundwater moves radially away from the airfield towards several drainages. Receptors exist in the various drainages that recieve groundwater emanating from the airfield. Such as Piscataway Creek, Charles Branch.

Contaminants: Lead 20.0 ug/L

Soil: Low Risk

Rainfall may promote leaching of metals from the sludge into groundwater, or runoff into surface water. Limited amount of runoff due to extensive infiltration in airfield makes recptors of affected surface water limited. No known groundwater receptors.

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.

Note: The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.

Data: All data comes from the Defense Environmental Restoration Program and the U.S. Army Corps of Engineers, and will be released soon at the ProPublica Data Store. Read our methodology »
