Abstract:

In 1986, the U.S. Environmental Protection Agency EPA issued a Hazardous Waste Management Permit to Aberdeen Proving Ground APG, Maryland. The permit required a Resource Conservation and Recovery Act RCRA Facility Assessment RFA of sites in the Aberdeen Area AA of APG. Recommendations from a draft RFA report suggested further investigations at the Fire Training Area FTA. This study is in response to the recommendations. Three soil borings and twelve groundwater monitor wells were installed. Three rounds of groundwater sampling and analyses were conducted. APG lies in the Coastal Plain Physiographic Province which is underlain by sediments consisting of three major units, the Potomac Group, the Talbot Formation, and Recent Holocene sediments. The Lower Cretaceous sediments of the Potomac Group lie unconformably on the older Precambrian rocks. In the early 1960s fire training was initiated and training has been conducted as often as once a week. Trenches were ignited after being filled with oil and water. The exercises concluded in 1989. During the RFA shallow boring soil gas surveys were conducted for volatile organic compound VOC contamination at the FTA. Deeper borings were conducted for monitor wells and geologic mapping. Sampling and monitoring of groundwater, surface water, and soils was conducted. Analyses of groundwater from the monitor wells and two supply wells indicate the AFTA is contributing chemical contaminants to the upper aquifer, which is at a depth of approximately 30 feet below ground surface. ....Aberdeen Proving Ground, Maryland, Hydrogeology, Groundwater, Site characterization, Groundwater contamination.
