Prince George’s County, MD
GTA is responsible for Phase I and Phase II ESAs for the 45-acre redevelopment of a historic, but environmentally contaminated, former industrial property into residential community for a national home builder. The site was historically used by the Washington Brick Company, which began operations of a brick manufacturing and clay mining facility in the early 1900s. In 1991, the site was partially used for recycling of non-hazardous petroleum impacted soils in conjunction with the brick manufacturing. This site is one of the first developments to be accepted into Maryland Department of the Environment’s (MDE’s) Voluntary Cleanup Program (VCP) that included single-family residences. GTA is implementing a Response Action Plan (RAP) that includes capping and engineering and institutional controls. Laboratory analysis of samples collected from the site reported elevated concentrations of petroleum constituents and metals in soil, and petroleum constituents and VOCs in groundwater. In addition, 26,000 tons of petroleum impacted soil (controlled by the MDE’s Oil Control Program) was removed from the property.
