Should we test for anything besides arsenic?

  • 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.
