Beginning in 2003, the RI Department of Health and the University of Rhode Island Cooperative Extension completed assessments of all major water suppliers as part of the Rhode Island Source Water Assessment Program (SWAP). These assessments focus on the drinking water supply watersheds and groundwater recharge areas where “source water,” from streams, lakes, and interconnected underground aquifers, recharges water supply wells and replenishes water supply reservoirs. In many cases, the water service area is not the same as the source water area from where the water comes.
To find out where your water comes from, visit the RI Water Resources Board.
To obtain assessment results for small community public water systems not included here, visit the RI Department of Health website.
