About the Drinking Water Source Protection Program

The 1996 amendments to the Safe Drinking Water Act required that all states develop source water assessment programs to assess the risk of accidental contamination of all drinking water sources. Source protection requirements are voluntary for EXISTING (i.e., plans and specifications submitted before July 26, 1993) ground-water sources serving transient non-community systems.

Rules have been adopted regarding the protection of public drinking water sources. These rules require that each public drinking water supplier prepare a source protection plan. This plan must be reviewed and approved by the Division of Drinking Water. Source protection requirements apply to both new and existing sources.

Typically, a plan is developed after a hydrogeological evaluation is conducted for each source. The investigation determines what areas must be protected, and the extent of protection which is necessary. Within these protection zones, various activities or facilities may be restricted if they will jeopardize the purity of the drinking water source.
