Source Water Assessment

Why have a Source Water Assessment Program?

Source water is the groundwater or surface water that provides drinking water for a public water system. The federal Safe Drinking Water Act Amendments of 1996 required states to develop and implement Source Water Assessment Programs to analyze existing and potential threats to the quality of the public drinking water throughout the state.

The 1996 amendments required the state of Nevada to delineate the areas that are sources of public drinking water, identify potential contaminant sources within the delineated area, assess the water systems' susceptibility to contamination, and to inform the public of the results.

The Nevada Division of Environmental Protection, Bureau of Safe Drinking Water, is the agency with primacy for development and implementation of the state of Nevada Source Water Assessment Program. Primacy designation by the federal Environmental Protection Agency (EPA) allows states to administer Source Water Assessment programs within their respective states.
