Water: Source Water Protection

Septic Systems and Source Water Protection

Septic systems treat and disperse relatively small volumes of wastewater from individual homes or small numbers of homes and commercial buildings. When properly sited, designed, constructed and operated they pose a minimal threat to drinking water sources but when improperly used or operated, septic systems can be a significant source of ground water contamination. Septic system regulation is usually a state, tribal or local responsibility.
