PFAS (“forever chemicals”)
EPA UCMR 5: 3 entry points tested Nov 2023 to Aug 2024. "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 One sample above limit Limit 4 ppt | 2.75 ppt 69% of the limit |
| PFOS Not detected Limit 4 ppt | – |
| PFHxS Not detected Limit 10 ppt | – |
| 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) Not detected Limit 1 | – |
| PFBS Not detected Guideline 2,000 ppt | – |
| PFBA Detected, below limit Guideline 6,000 ppt | 3.65 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 1.1 ppt |
| PFPeA Detected, no limit | 2.73 ppt |
New Jersey has its own PFAS limits. PFOA 14 ppt (this system's highest average: 2.75 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.
29 PFAS tested, 4 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 2 of 10 samples. Highest result 14 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: 0.85 ppb lead (Jan 2026 – Jun 2026). Below action level
Highest since 2016: 6.71 ppb (Jun 2022).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2026 – Jun 2026 | 0.85 ppb |
| Jul 2025 – Dec 2025 | 0.98 ppb |
| Jan 2025 – Jun 2025 | 1.08 ppb |
Earlier results (9)
| Jul 2024 – Dec 2024 | 0.62 ppb |

| Jul 2023 – Dec 2023 | 1.22 ppb |
| Jan 2023 – Jun 2023 | 1.22 ppb |

| Jul 2021 – Dec 2021 | 0.86 ppb |
| Jan 2021 – Jun 2021 | 1.02 ppb |
| Jul 2020 – Dec 2020 | 0.97 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 |
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)
| Contaminant | Highest | Guideline |

| Manganese | 29 ppb | 300 ppb |
| Chromium-6 | 0.48 ppb | – |
| Chlorate | 140 ppb | 210 ppb |
| Strontium | 7.76 ppm | 1.5 ppm |
| Molybdenum | 20.1 ppb | 40 ppb |

Questions
Is Woodbridge tap water safe to drink?
Most of Woodbridge gets its water from Middlesex Water Company. Middlesex Water Company had 1 health-based violation since 2016, all since resolved. EPA testing found no PFAS above the federal limits. 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 Woodbridge water have PFAS?
Yes. EPA's 2023–2025 testing of Middlesex Water Company found 4 PFAS at least once. None of the averages were above the federal limits.
What is the lead level in Woodbridge water?
The most recent 90th-percentile lead result for Middlesex Water Company is 0.85 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.
