					 comparison between centralized or decentralized treatment and disposal and
					 IOWDS
18. Fecal Coliform -
					 indicator bacteria common to the digestive systems of warmblooded animals that
					 is cultured in standard tests to indicate either contamination from sewage or

ml
or most probable number (MPN)
19. Federal Clean Water Act - federal
					 legislation amended in 1972 to regulate discharges of pollutants into the water
					 of the United States. It gave the
United States Environmental

					 pollutants from a point source into navigable waters, unless a permit was
					 obtained under its provision
20.
					 Functioning - an IOWDS that has no hydraulically overloaded soil conditions,
					 seepage or discharge to the surface of the property of the generator
21. Failure - breakage, weakness, or defect
					 that causes a malfunction in the treatment, distribution, disposal, or
