Source Water Protection Program

Montana is required under 1996 amendments to the federal Safe Drinking Water Act to carry out a Source Water Assessment Program (SWAP). Among other things, the SWAP requires the participation of all public water systems (PWSs) in identifying and protecting their water sources.
Montana’s program has been developed using the maximum possible public participation, including input from PWSs.
