Where Somerset County's water comes from

Somerset County homes get water from New Jersey American Water's Raritan system, and private wells in less developed areas. New Jersey's Private Well Testing Act requires a certified-lab well test when a home is sold, and every five years for landlords[1].

Key issues

  • Hard water and chloramine: New Jersey American Water reports 5–13 gpg hardness and chloramine disinfection for its Raritan system[2]. See hard water and chloramine.
  • Arsenic in wells: 5.7% of 89,206 tested New Jersey wells exceeded 5 µg/L, with the highest rates in Bergen, Hunterdon, Mercer, and Somerset counties[3]. See arsenic.
  • PFAS: 11.2% of New Jersey private wells tested from December 2021 through 2023 had at least one PFAS above a state standard[1], and many utilities reported PFOA or PFOS above the 4.0 ppt federal limit that takes effect in 2029 in EPA sampling[4].
