Chlorinated ethanes
WebThe degradation of selected halogenated ethanes was studied in anoxic sediment-water suspensions at 1 to 20% sediment concentrations. Batch kinetic experiments were used to quantify decay. Eh measurements of all suspensions were below -100mV (vs SHE), indicating reduced environmental conditions. WebGroundwater at an active industrial facility located in São Paulo, Brazil, impacted with CVOCs, including chlorinated ethenes, ethanes and methanes. There are two separate plume areas of concern. The first plume measures 50 m long x 50 m wide x 4 m deep (from 14 to 18 mbgs) with baseline total CVOCs concentrations up to 7,926 µg/L.
