WebDescription. Cometabolic bioremediation occurs when an enzyme or cofactor, produced by a microbe to catalyze the degradation of its metabolic substrate, is also capable of degrading target compounds. Cometabolic bioremediation is designed to target contaminants of concern (COCs) by stimulating or augmenting this biological process. WebTrichloroethylene (TCE) [ZIP] Tetrachloroethylene (PCE) [ZIP] Guidance Documents. Three categories of guidance documents provide some of the best ways to investigate and clean up contamination in soil and ground water. They differ from the Remediation Closure Guide in that they do not include rules or requirements. cancer council ads
