        Steps in assessing vulnerability

        Nevada's Source Water Assessment Program consists of a 4 step program:

        • Step 1: Determine the water system sources and delineate the assessment area. In the case of wells the assessment area is the capture area or area near the well that is within 2 year, 5 year, and 10 years of pumping of the well.
        • Step 2: Conduct an inventory of potential sources of contamination with the assessment area of each intake. Potential sources of contamination include those locations or sites that use or store chemicals, water bodies, and natural deposits.
        • Step 3: Determine the contamination vulnerability of each water system source (wells, springs, and intakes) to contaminants. Regulated contaminants include those designated by both the federal government and the state of Nevada.
        • Step 4: Publish the results of the Source Water Assessment Program for each public water system in the form of assessment summaries and reports. Links to published summaries and reports can be found below. The results from the SWAP program can be used in Source Water Protection Programs in the future. These protection programs will enable the protection of valuable sources of public drinking water from potential contamination.
