Description:
Soil cores were collected within and adjacent to a trichloroethylene plume that had contaminated the shallow aquifer at Picatinny Arsenal, New Jersey, to study the rate of contaminated cis-1,2-dichloroethylene biotransformation. oil cores also were collected at a highly contaminated site within the plume to determine the effect of different electron donors on the rate of cis-1,2-dichloroethylene biotransformation under methanogenic conditions. round-water samples were analyzed for volatile organic compounds to study the relation between volatile-organic-compound concentrations and the biotransformation of cis-1,2-dichloroethylene. iotransformation in microcosms from sites within the plume ranged from slight to more than 90 percent after an incubation period of 32 weeks. he most extensive biotransformation in soil microcosms occurred at a site near the highest in situ cis-1,2-dichloroethylene concentration measured at the arsenal (710 micrograms per liter). iotransformations was negligible at an uncontaminated site. mendment of soil microcosms inhibited the biotransformation of cis-1,2-dichloroethylene. ombination of methanol and formate had the greatest inhibitory effect.
