- Detected, below limit1 of 29 PFAS found at least once. All averages below the federal limits.
- 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 2026 – now, still in progress (results reported so far). Your home's pipes can make yours higher.

PFAS (“forever chemicals”)
EPA UCMR 5: 2 entry points tested Dec 2023 to Sep 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 Not detected Limit 4 ppt | – |
| 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 Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
| PFPeA Detected, no limit | 1.1 ppt |
29 PFAS tested, 1 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
Not detected in 6 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 0 ppb lead (Jan 2026 – now (in progress)). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2026 – now (in progress) | 0 ppb |
| Jan 2023 – Dec 2025 | 0 ppb |
| Jan 2020 – Dec 2022 | 0 ppb |

| Jan 2005 – Dec 2007 | 3 ppb |
| Jul 2002 – Dec 2002 | 8 ppb |

| Jan 1992 – Jun 1992 | 10 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
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 | 48.1 ppb | 300 ppb |
| Chromium-6 | 0.11 ppb | – |
| 1,4-Dioxane | 4.7 ppb | 0.35 ppb |
| Chlorate | 220 ppb | 210 ppb |
| Strontium | 0.054 ppm | 1.5 ppm |
| Vanadium | 0.54 ppb | 21 ppb |

Questions
Is Wilmington tap water safe to drink?
Most of Wilmington gets its water from CFPUA-Wilmington. CFPUA-Wilmington has no health-based violations since 2016. 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 Wilmington water have PFAS?
Yes. EPA's 2023–2025 testing of CFPUA-Wilmington found 1 PFAS at least once. None of the averages were above the federal limits.
What is the lead level in Wilmington water?
The most recent 90th-percentile lead result for CFPUA-Wilmington is 0 ppb, for the monitoring period that began Jan 2026 (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.
