Amendment of Cr(VI)-contaminated soil (approx. 200 mg/kg) with various treatments resulted in greater CO2 evolution and Cr(VI) reduction with organic amendments relative to controls receiving no organics, indicating bacterial reduction of Cr(VI) under anaerobic conditions. Isolation of Cr(VI)-reducing, indigenous bacteria, representative of the dominant soil population, further indicated Cr(VI) reduction by indigenous bacteria. Although desorption of Cr(VI) was evident with some treatments, its reduction was not affected.
