Problem
Each of the study areas has environmental problems associated with past practices at Aberdeen Proving Ground, which was formerly a center for the development and testing of chemical warfare agents and is currently an active Army base. Carroll Island and Graces Quarters were open-air test sites for chemical agents from the late 1940's through 1971. The Bush River area contains a chemical agent storage yard, and the Lauderick Creek area includes a former Nike missile battery. Each of the sites is the subject of one or more Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) investigations.
Objectives
- Identify the location and dimensions of disposal and test sites.
- Define the hydrogeologic system.
- Verify whether contaminants were or are being released from disposal and test sites.
- Model the hydrogeologic system.
- Evaluate the hydrogeologic effects of various remediation scenarios.
- Provide technical advice and limited data collection in support of other environmental investigations at the sites.
Approach
- Compile and interpret existing data.
- Collect and interpret hydrogeologic data through well installation, water-level measurements, and hydrologic testing.
- Collect environmental samples and interpret data.
- Construct a ground-water-flow model of Graces Quarters.
- Use the model to evaluate pump-and-treat scenarios.
- Review reports, participate in meetings, and collect water-level data to support other investigations.
- Develop solute-transport models for Graces Quarters.
