Testing Options

It is not recommended that homeowners go out and buy a home test kit to check arsenic levels in their water. NJDEP’s Office of Quality Assurance provides lists of certified labs and they can be reached by phone at 609-292-3950 for more information. The labs below are certified to sample private wells and analyze drinking water for arsenic by the most sensitive method available (EPA Method 200.8).  Clicking on the laboratory name will bring you to their website.

If your well water has not been tested within the past 5 years county health officers recommend requesting testing for the full set of Private Well Testing Act contaminants. If your well water has ever exceeded state standards for any of the contaminants it should be tested yearly for those contaminants, including where treatment systems have been installed. Residents of every county where arsenic may be an issue (Bergen, Essex, Hudson, Hunterdon, Mercer, Middlesex, Morrris, Passaic, Somerset, Sussex, Union, and Warren) should also test for total coliform, e. coli if positive for total coliform, nitrate, iron, manganese, pH, VOCs, lead and gross alpha in addition to arsenic. Yearly tests for total coliform, e. coli if positive for total coliform, and nitrates are recommended. As of May 2012, testing costs in these labs ranged from $30 to $100 for arsenic and from $359 to $600 for all ten Private Well Testing Act contaminants.
