A laboratory biodegradation test for anaerobic dechlorination of tetrachloroethene (PCE) to ethene was designed to determine the potential for site samples to support rapid PCE transformation by providing a complete mineral supplement and excess electron donor. A 100-mL groundwater sample from one site spiked with 50 {micro}mol PCE produced 17 {micro}mol ethene in 22 days, supporting the proposal that natural attenuation of contamination was occurring. A soil sample from a second site in 100 mL test medium converted 10 {micro}mol PCE completely to ethene in 10 days, providing evidence that the recent spill could be responsible for observed biotransformation products.
