Private Well Testing

Did you know that if you drink water out of a private water supply, you should test your water source at least once each year and anytime the well is serviced or the water changes in look, smell or taste?

Did you know the contaminants that you should test for can be dependent on where you live in the state? The testing you need will depend on the actual source of your water, the historic and current land use practices, and your specific worries or concerns about your water and your overall health.
