Everyone has a role to play in keeping our sources of drinking water safe and clean. If you would like to know what the Susceptibility Rating of your watershed is, please visit the Source Water Assessment Program (SWAP) page. This number tells you how susceptible your drinking water supply may be to contamination due to natural conditions and potential contamination sources. What it does not (currently) account for are the many ways we can protect water supplies and ensure its safety due to non-point sources of pollution such as runoff from cities and farms. We need your help to institute these protections and better ensure protection of our water resources. Here are a few things you can do to help out.
