Why test for lead in Rhode Island
On a private well, lead almost always comes from the metal the water touches on its way to your glass, and corrosive water decides how much. Read our lead explainer.
About 112,853 people in Rhode Island used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [1] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: Rhode Island.
