Chlorination of drinking water and wastewater generates a group of byproductsincluding haloacetic acids (HAAs) that pose serious risks on human health. Dominantbacterial populations functioning in the biodegradation of HAAs in drinking water, pipewall biofilm, granular activated carbon (GAC) filter biofilm, and wastewater wereinvestigated by continuous enrichment and isolation of organisms capable of growth withthree dominant HAAs, monochloroacetic acide (MCAA), dichloroacetic acid (DCAA), ortrichloroacetic acid (TCAA), as sole carbon and energy source. Phylogenetic analysis,dehalogenase genes, and characterization of HAA degradation of the organisms in theenvironment is underway. Includes 16 references, figures.
