This case study reviews the site of a chlorinated solvent spill as part of former dry cleaner operations at a retail shopping center in St. Petersburg, Florida. AECOM®, a global environmental consulting firm, was engaged to develop a solution for the site. The application called for an in situ groundwater treatment of low-concentration chlorinated volatile organic compounds (CVOCs). AECOM enlisted REGENESIS® to design and implement an innovative sorption-enhanced reductive dechlorination (ERD) bioremediation approach for treating the CVOC contaminants. The results of the effort led to the Florida Department of Environmental Protection, Southwest District issuing a Site Rehabilitation Completion Order, releasing the property owner from further obligation to conduct remediation at the project site (i.e., site regulatory closure).
