Perfluorooctanoic acid
4.9ng/L
Each block = 4.0 ng/L federal MCL (2024)
Short answer: PFOA is above its federal limit (a 2024 limit that water systems have until at least 2029 to meet); 3 more are detected with no federal limit, and everything else measured is within its reference or not detected. City of Irving serves 264,546 residents.
Your water bill or annual water quality report names your actual supplier.
The bar is drawn in blocks of the 4.0 ng/L federal MCL (2024), so the length shows how far above it the result sits.

CITY OF IRVING (EPA PWSID TX0570050) delivers surface water to 264,546 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. The utility's 2024 CCR reports chloramine disinfection.
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.
Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
PFOA 4.9 ng/L, above the 4 ng/L limit (+7 more PFAS detected)
lead 1 µg/L, below the 15 µg/L action level (detected below the limit); 466 galvanized lines to replace (context, not a tap measurement)
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.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Irving, PFOA 4.9 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 1 µg/L against the 15 µg/L action level. CITY OF IRVING (PWSID TX0570050) has a Purity Score of 76/100 (confidence: high), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
CITY OF IRVING (PWS ID TX0570050) is the public water system on record for Irving, Texas, serving about 264,546 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2023-07-11 to 2024-04-08), PFOA was measured at 4.9 ng/L against a 4 ng/L federal limit. PFBS (5.6 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (11.9 ng/L, below the 400,000 ng/L state limit), PFHxS (3 ng/L, below the 10 ng/L federal limit) and PFOS (4 ng/L, below the 4 ng/L federal limit) were also detected. PFBA (11.8 ng/L), PFHpA (3.2 ng/L) and PFPeA (11.7 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
CITY OF IRVING's most recent lead 90th-percentile result (2022–2024) was 1 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
PurityMap's current record for Irving holds 33 findings: 1 above a reference, 8 detected within the reference, 3 detected with no limit and 21 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
