Researchers at Airlift Environmental LLC, an SRP-funded small business, are developing slow-release permanganate candles to remove trichloroethylene (TCE) from groundwater through a chemical reaction. TCE is a widely used metal degreasing agent and can move readily through soil into groundwater.
|Technology||Slow-release oxidant candles with pneumatic circulators that are directly inserted into groundwater aquifers|
|Innovation||The candles improve treatment of TCE-contaminated aquifers by providing a way to treat TCE over time. In a five-year performance review, they show that the oxidant candles slowly released potassium permanganate when inserted into an aquifer, which steadily reduced migrating TCE concentrations. They are performing numerous on-site trials so the efficacy of the candles can be quantified under a range of hydrological conditions.|
