Public Water Systems (PWSs) are responsible for protecting their sources of drinking water from contamination. This rule sets forth minimum requirements to establish a uniform, statewide program for implementation by PWSs to protect their groundwater sources of drinking water. PWSs are encouraged to enact more stringent programs to protect their sources of drinking water if they decide they are necessary.

This rule applies to groundwater sources and to groundwater sources which are under the direct influence of surface water which are used by PWSs to supply their systems with drinking water. However, compliance with this rule is voluntary for existing groundwater sources of drinking water which are used by transient non-community water systems.
