This land is divided among 821 Drinking Water Supply Management Areas (DWSMAs). Water from one or more DWSMAs is aggregated at a PWS before distribution to consumers. We summarize data on the costs and benefits of source water protection at the PWS, DWSMA, and parcel level (Appendices A, B, and C) as appropriate. Our final report addresses three aspects of source water projection planning: 1) mapping land use change and land protection costs, 2) valuation of the multiple public benefits of land protection for clean water, and 3) enabling assessment of equity in source water protection. Our work highlights potential risks and opportunities to protect water quality and provide multiple public benefits, helps to identify programs that protect the value of clean water, and builds capacity among citizens and decision-makers to take action in source water protection areas to improve water quality and realize additional public benefits from land protection.ensource watersocial cost of nitrogenDWSMAReport
