Is Ridgewood, NJ tap water safe?
Supplied by Ridgewood Water · serves 61,700 people (20,481 connections) · Purchased surface water · EPA ID NJ0251001
Data: U.S. EPA · How we read the data · How we check it
Buys water from Veolia Water New Jersey Hackensack, Hawthorne Water Department, Veolia Water New Jersey Franklin Lakes, Passaic Valley Water Commission. Treated water bought from another system can carry that system's contaminants.
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, PFOS above the federal limit in EPA's 2023–2025 testing (PFOA 30.6 ppt vs a limit of 4 ppt, PFOS 13.3 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level2.61 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 ending Jun 2026. Your home's pipes can make yours higher.
- Violations
- Resolved1 health-based violation since 2016, most recently Jul 2019.
- 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 Ridgewood Water'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 (201) 670-5521. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 17 entry points tested Mar 2023 to Mar 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.
| Contaminant | Highest average |
|---|---|
| PFOA Above limit Limit 4 ppt | 30.6 ppt 7.65× the limit |
| PFOS Above limit Limit 4 ppt | 13.3 ppt 3.32× the limit |
| PFHxS Detected, below limit Limit 10 ppt | 4.8 ppt 48% of the limit |
| PFNA Not detected Limit 10 ppt | – |
| HFPO-DA (GenX) Not detected Limit 10 ppt | – |
| Hazard Index (a combined score for PFHxS, PFNA, GenX and PFBS, where above 1 is over the limit) Detected, below limit Limit 1 | 0.48 |
| PFBS Detected, below limit Guideline 2,000 ppt | 8.2 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 9.7 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 15 ppt |
| PFPeA Detected, no limit | 23.4 ppt |
| PFHpA Detected, no limit | 6.95 ppt |
| PFHpS Detected, no limit | 1.5 ppt |
New Jersey has its own PFAS limits. PFOA 14 ppt (this system's highest average: 30.6 ppt, above it), PFOS 13 ppt (this system's highest average: 13.3 ppt, above it), 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 98% of the New Jersey systems EPA tested and the PFOS average is higher than at 99% of the New Jersey systems EPA tested.
29 PFAS tested, 9 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.
Lithium
Detected in 8 of 38 samples. Highest result 11.9 ppb. EPA's non-enforceable screening level is 10 ppb. Below screening level The screening level is how EPA decides what to study further, not a health limit. There is no federal limit for lithium and no filter is certified to remove it. About lithium.
Lead and copper
Latest 90th percentile: 2.61 ppb lead (Jan 2026 – Jun 2026). Below action level
Highest since 2016: 6.28 ppb (Dec 2016).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2026 – Jun 2026 | 2.61 ppb |
| Jul 2025 – Dec 2025 | 3.91 ppb |
| Jan 2025 – Jun 2025 | 2.76 ppb |
Earlier results (9)
| Jan 2024 – Dec 2024 | 2.7 ppb |
| Jan 2023 – Dec 2023 | 5.12 ppb |
| Jan 2022 – Dec 2022 | 3.49 ppb |
| Jan 2021 – Jun 2021 | 0 ppb |

| Jan 2018 – Dec 2018 | 3.61 ppb |
| Jul 2017 – Dec 2017 | 4 ppb |
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.
Violations
| When | What happened |
|---|---|
| Jul 2019 | The water chemistry that keeps lead from dissolving out of pipes was outside the range the state set. EPA record: Lead and Copper Rule · WQP Entry Point/Tap Treatment Technique Non-Compliance (limit TT ) Resolved |
3 unresolved monitoring or reporting violations: Lead and Copper Rule, E. coli.
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.
Earlier EPA testing (2013–2020)

| Manganese | 26.1 ppb | 300 ppb |
| Chlorate | 210 ppb | 210 ppb |
| Chromium-6 | 2.9 ppb | – |
| 1,4-Dioxane | 0.21 ppb | 0.35 ppb |

Questions
Is Ridgewood tap water safe to drink?
Most of Ridgewood gets its water from Ridgewood Water. Ridgewood Water had 1 health-based violation since 2016, all since resolved. 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 Ridgewood water have PFAS?
Yes. EPA's 2023–2025 testing of Ridgewood Water found 9 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS: PFOA 30.6 ppt, PFOS 13.3 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in Ridgewood water?
The most recent 90th-percentile lead result for Ridgewood Water is 2.61 ppb, for the period ending Jun 2026. 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.
