The facilities built at this site were of block construction and similar to other NIKE sites. Facilities constructed at the Launch Area include the Acid Fueling Building, Barracks, Gate House, Generator Building, Kennel, Missile Assembly and Test Building, oil shed, sand filter building, three USTs, three missile silos, electrical utility system, and other miscellaneous site improvements. The facilities built at the Control Area include nine control and barracks buildings as well as art aeration pond, radar tower, sewage treatment Facilities, five USTs, an electrical distribution system, and other site improvements. The installation was not subject to other than DOD use and control during the period the property was used by the Army. The former Launch Area is currently leased by Charles County to the Maryland Indian Heritage Society for use as cultural center. The Maryland Indian Heritage Society uses all former DOD site improvements with the exception of one UST and the missile silos The facilities at the former Control Area are currently unused; however, Charles County maintains the site grounds. Portions of the former access road property are currently owned and used by Charles County, Prince Georges County and the GSA. The former Launch Area buffer zone is owned and used by Percontee, Inc. All former DOD improvements associated with the site have been removed or used by subsequent property owners, except the items proposed for removal. (Source: U.S. Army Corps of Engineers) « see less
2 Hazardous Sites
Below are the locations of hazardous sites associated with this military installation, according to the DOD. A site’s contamination may affect a much larger area, including public and private lands and the water supplies beneath them.
High Risk
Medium Risk
Low Risk
Risk Not Evaluated or Not Required
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.
1 Active Site
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.

This site is under ongoing monitoring until Sep 2043
Contaminated Areas
Groundwater: Medium Risk
Contaminated groundwater has moved off-site and migrated under several down gradient lots, which are undeveloped at this time. The lots above the groundwater do not have homes, but building is planned for the near future. Modeling shows that contaminant concentrations should not cause vapor problems in basements of the proposed homes. Drinking water in the area is supplied by a public water system.
Contaminants: DDD 0.03 ug/L Benzene 0.4 ug/L Toluene 0.7 ug/L Methyl tertbutyl ether (MTBE) 4.0 ug/L Trichloroethylene (TCE) 7.0 ug/L Chloroform 19.0 ug/L Carbon tetrachloride 180.0 ug/L
Soil: Low Risk
Contaminantion migration caused by surface runoff. Site is largely inaccessible based on the security fense. Potential for trespassers.
Contaminants: Beryllium and compounds 0.82 mg/kg DDT 1.8 mg/kg Benzo[b]fluoranthene 2.4 mg/kg Benz[a]anthracene 3.3 mg/kg Chrysene 3.5 mg/kg Pyrene 4.9 mg/kg Fluoranthene 6.9 mg/kg Lead 241.0 mg/kg
Surface Water (Human): Low Risk
Contaminants detected in water accumulated in former missile silos. Access to missile silos is limited.
Contaminants: Lead 70.0 ug/L
1 Inactive Site
Sites where military cleanup actions are complete, according to the DOD. Note that this status does not necessarily mean the site is no longer hazardous, as many of these sites are put under long-term monitoring or other restrictions.

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.
