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 10.8 ppt vs a limit of 4 ppt, PFOS 18.4 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
Lead
Below action level2.2 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 Dec 2023. Your home's pipes can make yours higher.

What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 10 entry points tested May 2023 to May 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.

What the utility says it is doing: The City of Vancouver says construction of a PFAS filter treatment system at Water Station 14 was scheduled to start Sept. 22, 2026, with completion expected by the end of 2027. Systems for Water Stations 4, 9, 3 and 1 are in design.

For context: the PFOA average is higher than at 99% of the Washington systems EPA tested and the PFOS average is higher than at 99% of the Washington systems EPA tested.

29 PFAS tested, 7 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.

Copper 90th percentile: 1.4 ppm (Jun 1992), action level 1,300 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.

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 City of Vancouver water safe to drink?

City of Vancouver 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 City of Vancouver water have PFAS?

Yes. EPA's 2023–2025 testing of City of Vancouver found 7 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS: PFOA 10.8 ppt, PFOS 18.4 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).

What is the lead level in City of Vancouver water?

The most recent 90th-percentile lead result for City of Vancouver is 2.2 ppb, for the period ending Dec 2023. 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.
