Summary

PFAS above the 2024 federal limits. Systems have until 2029 to meet the PFAS limits.

Is it an emergency? No: PFAS limits are about years of exposure, not a glass of water, and nothing in EPA's data calls for you to stop drinking the water today. If your utility ever issues a boil-water or do-not-drink notice, follow it.

PFAS
Above limitPFOA above the federal limit in EPA's 2023–2025 testing (PFOA 7.75 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
Lead
Below action level0 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period Jan 2024 – now, still in progress (results reported so far). Your home's pipes can make yours higher.

What you can do
  • Pregnant, or mixing baby formula with tap water? Babies drink more water for their size, so PFAS exposure matters more for them. Consider bottled water or a filter certified for PFAS for formula, and ask your doctor. Health effects.
  • To lower your PFAS exposure now, a home filter certified for PFAS reduction works (reverse osmosis, or activated carbon certified to NSF/ANSI 53 or 58). Filters for these results.
  • Built before 1986, or not sure what your service line is made of? Check your service line and test your tap. Utility data can't show your pipes.
  • Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
  • Read Washington Township Municipal Utilities Authority's annual water quality report (Consumer Confidence Report). It lists every regulated contaminant tested and is usually on the utility's website or mailed with your bill, and you can also request it at (856) 227-0880. EPA: how to find it.

PFAS (“forever chemicals”)

EPA UCMR 5: 11 entry points tested Mar 2025 to Sep 2025. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.

New Jersey has its own PFAS limits. PFOA 14 ppt (this system's highest average: 7.75 ppt), PFOS 13 ppt (this system's highest average: not detected), PFNA 13 ppt (this system's highest average: not detected). State compliance is judged on the state's own sampling, so ask the utility or the state program whether it meets them.

For context: the PFOA average is higher than at 75% of the New Jersey systems EPA tested.

29 PFAS tested, 5 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.

Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.

Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.

Questions

Is Washington tap water safe to drink?

Most of Washington gets its water from Washington Township Municipal Utilities Authority. Washington Township Municipal Utilities Authority has no health-based violations since 2016. EPA testing found PFAS above the 2024 federal limits, which systems must meet by 2029. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.

Does Washington water have PFAS?

Yes. EPA's 2023–2025 testing of Washington Township Municipal Utilities Authority found 5 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA: PFOA 7.75 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).

What is the lead level in Washington water?

The most recent 90th-percentile lead result for Washington Township Municipal Utilities Authority is 0 ppb, for the monitoring period that began Jan 2024 (still in progress). The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
