The water you drink

- Read your water quality report if it is online, or
- contact your water supplier to get a copy.

If your drinking water comes from a private well, you are responsible for your water's safety. EPA rules do not apply to private wells (although some state rules do), but EPA recommends that well owners have their water tested annually. Contact your state to get a list of certified commercial laboratories that test drinking water.
