VOLUNTARY REMEDIATION PROGRAM COMPLIANCE STATUS REPORT: THOMASVILLE NATIONAL BANK, 301 N. BROAD STREET, THOMASVILLE, THOMAS COUNTY, GEORGIA
Georgia Department of Natural Resources, 753 pp, 2019

Previous gasoline and dry cleaner operations conducted on the site of what is now the Thomasville National Bank led to VOCs and petroleum contamination in soil and groundwater below the bank building. VOCs were also found in the indoor air. Groundwater monitoring showed PCE, TCE, 1,2-DCE, BTEX, cyclohexane, methylcyclohexane, and MTBE constituents. A remediation test of enhanced reductive dechlorination zero-valent iron (ZVI) injection using ABC+, a mixture of ABC® and ZVI, was performed in March 2015 to verify the treatability effectiveness of injection, refine the technology assessment performance criteria, and evaluate the short-term attainment of preliminary remediation goals. Over 3 days, 9,750 lbs of ABC+ was injected into 10 points in 7 intervals from 12-30 ft below ground and was expected to actively reduce contaminants for up to 12 months. The building serves as a cap to prevent exposure to contaminated soils. Annual inspections will be performed to evaluate the integrity of the controls implemented at the property. Performance of vapor intrusion system diagnostic testing is planned so that effective sub-slab active soil depressurization can be designed and installed to prevent migration of VOCs into the building. https://epd.georgia.gov/sites/epd.georgia.gov/files/RoseCityCleanersCSR.pdf
