Chlorinated solvent contamination (TCE and PCE) impacted groundwater at multiple wells (MW-04, MW-07, MW-44) at depths of 20–30 feet below ground surface at a former manufacturing plant in southern Georgia. Both source area treatment and off-site migration control were required to achieve site remediation objectives.
Large-scale treatment using BAM (14 DPT points, 2,800 gallons) and ABC+ soybean electron donor with zero valent iron (6 DPT points, 1,200 gallons) was applied around MW-04 and MW-07, with 40 injection points per well. A BAM/ABC+ mixture was installed as a barrier wall around MW-44 to intercept and treat migrating contamination.
Three rounds of post-treatment sampling confirmed greater than 99% overall chlorinated solvent reduction site-wide at the former manufacturing plant in southern Georgia. MW-04 reached 95.3% reduction, MW-07 reached 99.9% reduction, and MW-44 reached 99.8% reduction. The combined BAM and ABC+ soybean electron donor with zero valent iron injection program addressed both source area contamination at MW-04 and MW-07 and off-site migration at MW-44, where a barrier wall configuration intercepted and treated migrating TCE and PCE. Treatment was delivered to depths of 20–30 feet below ground surface through 14 BAM DPT points and 6 ABC+ DPT points, with 40 injection points per well at the source area wells.
