Source Water Assessments

In 2003, through the Rhode Island Source Water Assessment Program, RI HEALTH and the University of Rhode Island Cooperative Extension completed assessments of all major water suppliers. Assessment results are available as full reports, summary fact sheets, and maps. These assessments focus on the drinking water supply watersheds and groundwater recharge areas where "source water" from streams, lakes, and interconnected underground aquifers recharge water supply wells and replenish water supply reservoirs. In many cases, the water service area is not the same as the source water area where the water comes. To find out where your water comes from or to obtain assessment results for all small public water suppliers not included in this list, go to the RI HEALTH website.

Several wellhead protection areas have been re-delineated within the past several years to take into account new groundwater modeling data. New SWAPs were prepared for these WHPA between 2006 and 2010 using the updated wellhead protection area boundaries. The updated SWAPs are provided below.
