SourceKill™ Destroys both Chlorinated Solvents and Freon-113 in Groundwater

Recently, TEA received various inquiries asking about the effectiveness of using our chlorinated solvent destroyer that treats source areas, SourceKill™, to treat sites affected by both chlorinated solvents and Freon-113 (trichlorotrifluoroethane). Freon-113 is often found in older TCE contaminated sites since it acted as both a stabilizer and an enhancement for the degreasing properties of solvents in cleaning of equipment.

In 2006, a federal government entity asked TEA to develop a bench scale test to test the efficacy of using emulsified zero-valent iron, (EZVI/SourceKill™) to treat TCE and Freon-113. We turned to a major university to design the bench scale test and to perform the treatability studies under strict university laboratory conditions. 

Private testing laboratories were also involved in the test to confirm the results. The university bench scale tests showed dramatic reductions in both TCE and Freon 113 in just four (4) days! (The study affirmed the continued effectiveness of EZVI/SourceKill™ to treat chlorinated solvents.) TCE concentrations were dropped by 98.8% and Freon 113 concentrations were reduced by 99.4%

Using this data, TEA designed and implemented both a field pilot study and a full-scale remediation for several sites with both COCs. Similar results were produced in these field applications.

SourceKill™ continues to prove that it is the nation’s leading source area, chlorinated solvent destroyer….and has the same efficacy to destroy Freon 113.
