Water Quality

Many Hopewell Township residents get their drinking water from a private well. Frequent testing is encouraged to protect your family’s health. Water testing is required during all real estate transactions under the New Jersey Private Well Testing Act. Landlords are also required to test their well water once every five years and to provide each tenant with a copy of the test results. Otherwise, it is recommended to test your private well drinking water at the intervals below: 

  • Every year (at least): Total coliform, nitrates, and pH
  • Every five years: Lead, VOCs, arsenic, iron, and manganese
  • At least once: Mercury, gross alpha, and uranium

Per- and Polyfluoroalkyl Substances (PFAS)

Per- and polyfluoroalkyl substances (“PFAS”) are a large family of thousands of manmade chemicals that have been used in industrial and commercial applications for over 70 years. Also known as “forever chemicals,” PFAS repel water and oil and are resistant to heat and chemical reactions. New Jersey currently regulates three substances - PFOA, PFOS, and PFNA - because it was determined that these three PFAS occur in groundwater and drinking water at levels of concern. These chemicals have been linked to numerous adverse health effects, including decreased birth weights, increased cholesterol and liver enzymes, thyroid disease, and kidney & testicular cancers.

PFAS Drinking Water Fact Sheet from NJ Department of Health

To reduce the level of PFAS in drinking water, you can install granular activated carbon filters or reverse osmosis water treatment devices. If a treatment is used, it is important to follow the manufacturer’s guidelines for maintenance and operation. NSF International, an independent and accredited organization, certifies products proven effective for reducing PFAS. (http://info.nsf.org/Certified/DWTU/).
