Project Experience: CL&N - Bill's Gulf


Client: CL & N Associates, Inc.

Location: Bill's Gulf Service Station, Cheshire, CT

Project: UST Contamination Assessment, Remedial Action Plan, Remediation System Design, Installation, Operation and Maintenance

Description:

Performed a contamination assessment, subsurface investigation, UST compliance history, and Clean-up Fund application preparation for the past and present gasoline tanks at the site. The project included direct involvement with the CTDEP and local fire marshal to determine the status of past and present operations and problems. A remedial action plan was developed and prepared, including remediation system design and specifications, and recommendations for upgrading UST operations to meet current regulations and requirements.

Based on the findings of the investigations, an aggressive remediation system was designed to remediate the groundwater and soil on the subject site and potential off-site contamination. The remediation included air and oxygen sparging, soil vapor extraction, bioremediation, and pump and treat with air stripping with GAC polishing. The system design was presented to the CTDEP and UST Clean Up Fund Review Board and approved for reimbursement as a Third Party. The remediation system was installed and start up completed in February 1997, with continued operation and maintenance, along with ongoing groundwater monitoring.
