Thompson Engineering provided construction engineering and inspection (CEI) and Quality Assurance/Quality Control (QA/QC) for 0.6 miles of floodplain restoration and stream restoration at Kilby Ditch in Montgomery, Alabama. The shallow groundwater plume that discharges into the ditch contains trichloroethylene (TCE), a colorless, volatile liquid that is produced in large volumes for commercial use.
The Alabama Department of Transportation (ALDOT) developed a Corrective Measures Implementation Plan (CMIP) for Kilby Ditch to control and treat the groundwater containing TCE. Thompson Engineering provided oversight for the implementation of the CMIP, which included:
Thompson also managed environmental documents and provided progress reports throughout the 361-day project.
