What do test results mean?

  • In New Jersey, the standard for arsenic is 5 micrograms per liter (abbreviated as "μg/L"). If arsenic levels are greater than 5 micrograms/liter, we encourage the use of bottled and/or properly treated water for all drinking and cooking, and encourage the installation of a treatment system.
  • Importantly, a negative test for arsenic does not mean that your water is safe with respect to other water quality parameters.
