Environmental Remediation of Metropolitan Police Department Firing Range
To convert an abandoned firing range into a one-acre, 77-space parking facility for the Metropolitan Police Department, Volkert Engineering conducted an EA (Environmental Assessment), prepared demolition and remediation plans, and designed the parking lot with a BMP stormwater management facility.
The purpose of the EA was to identify soil, sediment or surface water contamination from small arms firing and target practice activities and to make recommendations for corrective actions.
Phase I involved utility location to identify underground public utilities that may be on or near the property, a visual site inspection and reconnaissance, an environmental record search, a review of historical documents to evaluate past land use, and a surface and subsurface investigation. The primary contaminant of concern was lead in the soil and near the target berm and firing lines. In addition, selected soil samples were analyzed for residues from explosives (nitroaromatics) which may have been stored or used on the property. Surface, subsurface, and surface water samples were collected and analyzed for lead and other metals. The analysis indicated that the surface soils and sediment at the site were severely contaminated with lead but the deeper soils were not.
A Phase II EA was conducted to further delineate the lateral extent of lead-impacted surface soils. Further analysis confirmed that the significantly lead-impacted soil was confined to the surface soils. Volkert Engineering provided plans for demolition of existing buildings and lead remediation of the contaminated soils.
Volkert Engineering provided oversight remediation monitoring of 4,000 tons of lead contaminated soil. Volkert Engineering documented remediation activities (including pre- and post- activities) to verify compliance with OSHA, EPA and the District of Columbia regulatory requirements.
