ENVIRONMENTAL PROJECTS

CLIENT: Arnold Air Force Base, Tennessee
PROJECT: Seventy-two-hour aquifer pumping tests were conducted at two sites. Groundwater in the vicinity of these two sites was found to be contaminated by chlorinated solvent compounds. The purpose of the aquifer tests was to evaluate the groundwater flow regime and other aquifer characteristics. This information would be used to design an optimal groundwater remediation system that would capture the solvent plumes and provide for the removal and treatment of the contaminated groundwater. Critical tasks of this project included: (1) literature review; (2) field investigation; (3) determination of pumping well and observation well configurations for the tests; (4) conducting the multi-day, multi-site tests under adverse weather and air traffic conditions while containing the contaminated groundwater discharged during the tests; and (5) evaluating the maximum sustained yield and contaminant plume capture zone for each site.
