Solvent Assessment and Remediation, Textile Manufacturing Facility
A historical textile facility utilized a 6,000-gallon underground storage tank and later a 6,000-gallon aboveground storage tank to store solvents used for dry-cleaning operations. BLE was retained to investigate the extent of the contamination, which was ultimately identified in soil and groundwater throughout the site and adjoining properties. Two pump and treat systems and a soil-vapor extraction system (SVE) were installed as remedial measures. As part of a real estate transaction, BLE supported negotiation of a Brownfield agreement. To enhance and expedite remedial efforts, BLE identified that waste milk solution was routinely generated at the neighboring dairy facility. BLE performed a pilot study, which ultimately lead to injection of the milk solution to enhance bioremediation of the contamination. This green-sustainable bioremediation technology completely replaced the high cost and less efficient legacy remedial technologies formerly in-use at the site. This bioremediation project has substantially reduced contaminant mass and was the impetus for the successful property transaction.
