Bio degradation rates were evaluated under ambient anoxic conditions and in the presence of added potential electron acceptors (N03~, N02, S042) or metabolic inhibitors (2-bromoethanesulfonic acid (BESA), Mo042~) to promote different pathways of microbial ca tabolism (denitrification, sulfate reduction, or methanogenesis). Biodegradation rates varied substantially between sites; the various chemical amendments affected biod?gradation rates differently in soils from different sites. The results indicate that the studied sites can be categorized into two general types. Fast soils are characterized by a higher flux of water and nutrients, higher bio degradation rates, and rate enhancement with the addition of nitrate or sulfate. In slow soils, organic contaminants are de graded at lower rates, rates are decreased by adding N03, S042_, or BESA, and rates are increased by adding M0O42. J. Water Pollut.
