Source Water Protection

Lakes, streams, rivers, and aquifers are sources of drinking water for communities. In order to ensure a safe, adequate water supply, communities should protect water sources in critical groundwater and watershed areas through careful planning and land use decisions. Communities that plan for and maintain safe and plentiful supplies of fresh water can save money in the long run by avoiding costs associated with the cleanup of polluted water sources or finding alternative sources.

For information on source water protection, see APA’s Policy Guide on Water Resources Management,  "Protecting Drinking Water Resources under the Source Water Assessment Program" from the Winter 2001 issue of The Commissioner, and the June 2009 featured response on protecting water quality from the Planning Advisory Service’s Inquiry Answer Service.
