Groundwater

September 2016 Update - The U.S. Army Corps of Engineers, Baltimore District has finalized the Final Groundwater Remedial Investigation report for the Spring Valley Formerly Used Defense Site (FUDS). The Remedial Investigation report details the groundwater investigation findings to include a review of all the data collected to determine the nature and extent of groundwater contamination in Spring Valley from past Army activities. The Groundwater RI also includes a Human Health Risk Assessment, which evaluates risk to human health using different potential exposure scenarios for groundwater, including the potential future use of groundwater as a drinking water source.  As a reminder, Spring Valley groundwater is not currently used as a drinking water source.  

The Groundwater RI concluded that there is no unacceptable risk posed by groundwater under the current land use. Perchlorate and arsenic in groundwater were detected at levels that would pose a risk if groundwater was used as a drinking water source in the future in the area near Kreeger Hall on American University and near the Glenbrook Road disposal areas.  A Feasibility Study will be completed to evaluate a range of alternatives that would address the risk posed by the potential future use of groundwater as a drinking water source.
