The Source Water Assessment Program was required by the federal Safe Drinking Water Act Amendments of 1996 to determine the potential susceptibility of public water supply systems to contamination. The state's source water assessment plan document was submitted to the U.S. Environmental Protection Agency (EPA) in 1999 and the mandated completion date for all assessments was May 6, 2003. Although the work on the program took place from 2000 - 2003, information obtained during the assessments serves as the foundation for the Drinking Water Protection Program. Assessments will continue to be conducted for new or expanding water systems.
