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!



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.

Community Well Testing in Your Municipality

RHA partners with municipalities throughout the region to offer residents the opportunity to test their well water. Towns decide when to offer the testing, the test dates are advertised and RHA provides testing kits to town hall. On a designated day, residents bring their water samples to the municipal building where volunteers sort and then deliver the samples to the RHA office, where they are picked up by a state-certified laboratory for analysis. Test results come directly to us, and we share the results directly with residents. This program makes the important practice of regular well testing even easier and more convenient for residents.
