Well Testing


What’s in your water?

Make sure the water flowing from your tap is pollutant-free.  If your water comes from a private well, it’s up to you to make sure it is safe to drink!

We offer discounted water tests for a wide variety of pollutants to residents. Well test kits are available year round at our 2 office locations in Bedminster and Flemington. To make arrangements to pick up a well test kit and/or learn more about the tests we offer, please contact us.

Community Well Testing in Your Municipality

80% of the households in our region depend upon private wells for drinking water. 

While commercial water companies are required by law to test customers’ water, owners of private wells are on their own. The US Environmental Protection Agency recommends that household water be tested once a year to ensure the well is free from harmful bacteria and nitrates. Testing can be expensive, but RHA has established a program that provides residents of the Raritan Headwaters region water tests by a state-certified lab at reasonable rates. RHA partners with municipalities throughout the region to offer residents the opportunity to test their well water. This program makes the important practice of regular well testing even easier and more convenient for residents.
