Middlesex Water Co. and 3M Agree to $4.9M Settlement for PFAS Water Contamination

Middlesex Water Co. and 3M struck a deal. They’ll pay $4.9 million to roughly 60,000 customers whose tap water carried PFAS contaminants. The class-action suit, launched almost four years back, accused the companies of letting residents drink water tainted with PFOA at levels that broke state rules.

In October 2021, the problem came to light. The water company mailed warnings to residents after tests showed PFOA concentrations hit 36.1 parts per trillion — more than double New Jersey’s ceiling of 14 parts per trillion.

The deal was announced Oct. 3, 2025. Checks go out once a judge gives the green light.

Each household can grab a base payout of $50 without showing receipts. But families who saved proof of buying bottled water, filters, or paying for doctor visits connected to the tainted water can ask for as much as $2,500. This money pays back what people spent trying to protect themselves when the crisis hit.

Stephen DeNittis, the lawyer who ran the case, says this marks the state’s largest PFAS consumer victory. The lawsuit doesn’t chase personal injury claims. It zeroes in on returning money people paid out of their own pockets.

PFOA belongs to PFAS, which is shorthand for thousands of man-made chemicals rolled out since the 1940s in items like non-stick pans, rugs, and rain-resistant jackets. These compounds refuse to decompose in nature or inside human bodies. The World Health Organization’s cancer research division stamps them as Group 1 carcinogens.

The water company’s warning letter told residents that drinking this water over years might trigger high cholesterol, liver damage, weakened immune responses, and trouble with male fertility. Pregnant women, babies, older adults, and anyone with compromised immune systems got special advice: drink only bottled water and talk to your physician.

By 2023, Middlesex Water Co. had poured $52 million into carbon filtration systems and now hits state benchmarks. Testing revealed that more than half a million New Jersey residents across 34 water systems faced similar contamination threats, but this provider stood at the eye of the storm.

The EPA rolled out national PFAS caps on six chemicals during the Biden years in spring 2024. Come May 2025, the new administration pushed compliance deadlines back to 2031 and scrapped regulations for four of those six substances. Environmental watchdog groups dragged the rollback into court.

New Jersey imposed the country’s strictest PFOA threshold in 2020 after research tied it to tumors, thyroid disorders, and babies born underweight. The state keeps enforcing its 14 parts per trillion cap no matter what happens at the federal level.

Claim forms will show up in mailboxes for affected households scattered across central New Jersey. Residents need to watch for directions on turning in receipts if they want bigger payouts.
