Thanks for visiting the Idaho Source Water Protection Website!


The water in our aquifers, rivers, and lakes that provides drinking water to the public. These natural sources can be vulnerable to contamination from land use practices such as farming and potential contaminant sources such as gas stations within the vicinity of drinking water wells and intakes.

There are many ways to minimize this vulnerability and help keep public drinking water free from contaminants. It is critical that we take steps to protect our source water. 

Source water protection is a voluntary community effort to help prevent contamination of the source water that supplies its public water system. The effort may involve creating a source water or drinking water protection plan and implementing regulatory or non-regulatory management practices. Preventing contaminants from entering a public water system supply benefits the community by minimizing the problems that can occur from contaminants in the water supply such as increased health risks to the public, expanded drinking water monitoring requirements, additional water treatment requirements, and expensive environmental cleanup activities.

Source water protection is the responsibility of many, including the general public, local governments, and public water systems.

Who We Are

The Idaho Source Water Protection Collaborative consists of various federal, state, local, and nonprofit organizations and water purveyors that play a role in protecting Idaho’s drinking water sources.

The collaborative’s members are interested in protecting Idaho’s drinking water sources and recognize that all communities depend on clean drinking water supplies to protect and enhance public health, environmental quality, economic development, public finance, and quality of life.

  • Public water systems and water purveyors
  • Federal, state, and local governments
  • Resource managers
  • Businesses
  • The public
