The Iowa Source Water Protection program strives to protect all public drinking water from contamination, and is divided into three different phases:

1)  The 'Phase 1' assessment. Provided at no cost to the water supply by the state, these assessments detail the water system’s active wells, source water areas, susceptibility, and known potential contaminants.

2)  The Source Water Plan. If a community decides to protect its drinking water, it is encouraged to write a SWP Plan. These plans detail how the system will start to protect its drinking water resource.

3)  Implementation. After The plan has been submitted, a community can start to implement the items listed in the plan.

Information on each of Iowa’s 1,900 public water systems, including wells, production, protection, and history can be found via the “source water tracker” link at the top right of the page.
