ATLANTA – The U.S. Environmental Protection Agency (EPA) has begun remedial action (RA) work at the Sanford Dry Cleaners Superfund site in Sanford, Fla. The RA involves the actual construction or implementation phase of Superfund site cleanup.

The RA to address contamination at the site will be conducted in five phases:
• Site preparation;
• contaminated soil excavation;
• In Situ Enhanced Bioremediation (ISEB) injections;
• Soil Vapor Extraction (SVE) treatment system installation;
• and site restoration.

The work will involve excavating, backfilling, and restoring areas not covered by site buildings that contain soils with concentrations of contaminants of concern above soil cleanup levels. Soil removal will be performed using a backhoe or similar excavation equipment. Excavated soil will be loaded directly onto dump trucks and hauled to an appropriate landfill for disposal. Excavated areas will be backfilled with clean soil and restored to match pre-excavation conditions.

ISEB injections will involve injecting chemical compounds into the groundwater to increase the number and vitality of native microorganisms to treat the contaminated plume. The SVE Treatment System phase includes installing six vapor extraction wells inside the Site building. The systems will be used to extract contaminated vapors from soils. This process is expected to remediate contaminated soils beneath the building and mitigate contamination in indoor air. The SVE system will be equipped with off-gas treatment to protect the surrounding community from being exposed to the extracted vapors.

After RA completion, several long-term operation and maintenance (O&M) tasks will be implemented to ensure the effectiveness and protectiveness of the remedy. This will include: O&M of the SVE system; periodic sampling and analysis of the groundwater and indoor air; and the performance of five-year reviews at the site to ensure that the cleanup conducted remains fully protective of human health and the environment.
