FEROXSM Treatment of Freon-113
Recently completed laboratory studies looked at the effectiveness of FEROXSM in reducing 1,1,2-trichloro-1,2,2-triflouroethane (Freon–113). At one of our client's sites, Freon-113 was identified at elevated concentrations in both soil and groundwater. A treatability study was set up using representative soils and groundwater obtained from the site and entailed creating individual reactor vials with known quantities of Freon-113 (approximately 20 mg) and varying dosages of ZVI powder (0.0 g, 0.2 g, 1.0 g, 2.0 g, and 5.0 g). The reactors were analyzed at specific time periods (Day 0 through Day 52) by a certified laboratory.
The results of the treatability studies showed Freon-113 was effectively reduced to non-detect levels within 52 days in reactors containing 1.0 g of iron or more. ARS is encouraged by this data supporting FEROXSM treatment of Freon-113.
