PFAS & Water Safety
Read the facts
What is PFAS?
PFAS (per- and polyfluoroalkyl substances) are known as "forever chemicals." In 2021 the NJDEP adopted the strictest groundwater standards in the nation. Municipalities, including Mahwah, had to begin monitoring in 2022.
The reality in Mahwah
In December 2021, Mahwah was one of roughly 30 North Jersey towns notified that one of its wells, Well 19, exceeded the new PFAS limits. The township took the well offline and immediately began designing a filtration system to bring it back online.
The water wasn’t suddenly unsafe
The standard changed. Mahwah acted quickly.
$2.4 million in grants
$800,000 from the federal government and $1.6 million from the State of New Jersey. Grants covered most of the cost.
7 wells
Mahwah operates seven ground wells, which supply about 68% of the township’s water. The remaining 32% comes from Veolia.
Mahwah worked to get funded
Under the Administration, Mayor and Council, including Robert Ferguson, a member of the Council at the time, worked with State and federal legislators to secure the funding. Grant money goes to the towns that show up, document the need and keep asking.
More filtration. All wells.
The funding wasn’t just for Well 19. It allowed the township to enhance filtration in all of the wells and strengthen the long-term safety of our water system.
Ongoing funding opportunities
The EPA has announced $33.6 million for New Jersey under its Emerging Contaminants program, funding available for testing, planning and treatment infrastructure.
- Mahwah didn’t wait. The well was taken offline when it failed the new standard.
- The standard changed, not the safety of our water. New Jersey adopted the strictest PFAS limits in the country and 30 North Jersey towns were affected.
- Grants covered most of the cost: $800,000 federal and $1.6 million State, $2.4 million in all.
- The remainder is carried by the water utility on the rate, not the property tax levy.
