Washington Department of Health
January 2017
Overview
The Safe Drinking Water Act requires every state to develop a wellhead protection program. The state Department of Health (DOH) administers the wellhead protection program in Washington.
Most public water supply wells are located in or near communities. Washington’s wellhead protection requirements are designed to prevent contamination of groundwater used for drinking water. The requirements apply to all Group A1 public water systems that use wells or springs for
source water, except those that purchase their water or get their water through interties.
Public water systems must work with local governments and regulatory agencies to develop and implement their own local wellhead protection programs.
