Your water bill or annual water quality report names your actual supplier.
OKLAHOMA CITY (EPA PWSID OK1020902) delivers surface water to 644,000 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. Water hardness and disinfectant type are pending the utility's own annual report.
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
173 lead service lines; 6 galvanized lines to replace
PFPeA 4.7 ng/L detected (no federal or state limit)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2024-01-08 to 2024-10-07), PFPeA was detected at 4.7 ng/L. It has no federal or state limit, so PurityMap shows it without grading it. No PFAS with a limit was detected.
Lead is not in Oklahoma City's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
PurityMap's current record for Oklahoma City holds 31 findings: 1 above a reference, 1 detected with no limit and 29 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
