2. Do I really need an arsenic water treatment system?

  • Yes, if arsenic has been detected in your well water above the New Jersey Safe Drinking Water maximum contaminant level (MCL) of 5 micrograms per liter (mcg/L)
  • Arsenic is a toxic element. It is known that people who drink water containing elevated levels of arsenic have an increased risk of a wide range of adverse health effects.
    • Arsenic is known to greatly increase the risk of cancer in humans who drink water with elevated levels. Chronic exposure to high levels of arsenic is associated with a range of serious health problems including skin lesions, skin cancer, lung cancer, liver cancer and bladder cancer.
    • Arsenic exposure has also been associated with increased risk of cardiovascular disorders, neuropathy and diabetes. Studies show arsenic from drinking water has a negative effect on children's IQ.
  • When you sell your home, you will be required to test for arsenic and share the results with the buyer of your home. If the arsenic level is above the New Jersey arsenic standard of 5 mcg/L, a treatment system will be needed.
  • Even though the MCL for arsenic is 5 mcg/L in New Jersey, the US Environmental Protection Agency has set a maximum contaminant level goal of 0 mcg/l for arsenic in drinking water.
