Bacteria that can use either dissolved oxygen or chemically derived oxygen (from nitrate, sulfate or carbonate) for respiration and use organic materials for energy and growth. In other words, facultative heterotrophs can live under aerobic, anoxic or anaerobic conditions.
Fecal Coliform Bacteria
Coliform bacteria (microorganisms) found in the intestinal tract of warm-blooded animals (including humans). Unlike total coliforms, which include a number of normal soil inhabitants that are harmless, fecal coliforms are more reliable indicators of fecal contamination, which may result in the spread of intestinal disease.
Federal Safe Drinking Water Act
The Safe Drinking Water Act (SDWA) was established to protect the quality of drinking water in the U.S. This law focuses on all waters actually or potentially designed for drinking use, whether from aboveground or underground sources. The Act authorized EPA to establish safe standards of purity and required all owners or operators of public water systems to comply with primary (health-related) standards. State governments, which assume this power from EPA, also encourage attainment of secondary standards (aesthetic-related).
