Sampling of pubic and private wells that draw water from Southern New Jersey’s Cohansey aquifer and the Highlands Region of Northern New Jersey have shown elevated levels of naturally occurring radioactivity. For more information on this subject, and on testing your well, please download* one or both of the following documents:

A South Jersey Homeowner's Guide to Radioactivity in Drinking Water: Radium

A North Jersey Homeowner's Guide to Radioactivity in Drinking Water: Uranium

Under the Private Well Testing Act (PWTA), private wells must be tested as a condition of each contract for sale of real property. Please visit the DEP's PWTA website for more information at http://www.state.nj.us/dep/pwta
