PFAS (“forever chemicals”)
EPA UCMR 5: 2 entry points tested Feb 2024 to Nov 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 | – |
Pennsylvania has its own PFAS limits. PFOA 14 ppt (this system's highest average: not detected), PFOS 18 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, 0 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 8 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 9.78 ppb lead (Jun 2025 – Sep 2025). Below action level
Highest since 2016: 14.2 ppb (Sep 2022).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jun 2025 – Sep 2025 | 9.78 ppb |
| Jun 2022 – Sep 2022 | 14.2 ppb |
| Jun 2019 – Sep 2019 | 12.9 ppb |
Earlier results (9)
| Jun 2016 – Sep 2016 | 11.3 ppb |
| Jun 2013 – Sep 2013 | 11.5 ppb |
| Jan 2010 – Dec 2010 | 9.8 ppb |
| Jan 2007 – Dec 2007 | 12 ppb |
| Jan 2004 – Dec 2004 | 7 ppb |
| Jan 2001 – Dec 2001 | 6.8 ppb |
| Jan 2000 – Dec 2000 | 4.1 ppb |
| Jan 1999 – Dec 1999 | 12.8 ppb |
| Jul 1992 – Dec 1992 | 12.1 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 |
|---|---|
| Apr 2026 | The running annual average for TTHM was above the legal limit. EPA record: TTHM · Maximum Contaminant Level Violation, Average · measured 0.082 mg/l (limit 0.080 mg/L) Archived |
| Oct 2024 | The running annual average for TTHM was above the legal limit. EPA record: TTHM · Maximum Contaminant Level Violation, Average · measured 0.082 mg/l (limit 0.080 mg/L) 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 | 3.9 ppb | 300 ppb |
| Molybdenum | 1.6 ppb | 40 ppb |
| Strontium | 0.15 ppm | 1.5 ppm |
| Chromium-6 | 0.08 ppb | – |

Is Wilkinsburg-Penn Joint Water Authority water safe to drink?
Wilkinsburg-Penn Joint Water Authority had 2 health-based violations 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 Wilkinsburg-Penn Joint Water Authority water have PFAS?
EPA tested Wilkinsburg-Penn Joint Water Authority for 29 PFAS between Feb 2024 and Nov 2024 and none were detected above the reporting limits (about 2 to 20 ppt depending on the chemical).
What is the lead level in Wilkinsburg-Penn Joint Water Authority water?
