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); everything else measured is within its reference or not detected. Township of Wayne serves 55,000 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.

TOWNSHIP OF WAYNE (EPA PWSID NJ1614001) delivers surface water to 55,000 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.
PFOA 4.9 ng/L, above the 4 ng/L limit
lead 2.93 µg/L, below the 15 µg/L action level (detected below the limit); 36 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 Preakness, 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 2.93 µg/L against the 15 µg/L action level. TOWNSHIP OF WAYNE (PWSID NJ1614001) has a Purity Score of 70/100 (confidence: moderate), 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.
TOWNSHIP OF WAYNE (PWS ID NJ1614001) is the public water system on record for Preakness, New Jersey, serving about 55,000 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 (2024-11-12 to 2025-09-02), PFOA was measured at 4.9 ng/L against a 4 ng/L federal limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
TOWNSHIP OF WAYNE's most recent lead 90th-percentile result (2026) was 2.93 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 Preakness holds 31 findings: 1 above a reference, 1 detected within the reference 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.

Start with the hot-or-cold tap check. Where Township of Wayne reported something related, it's shown below.
Lead at Township of Wayne: 2.93 µg/L (90th percentile, 2026 monitoring period (still open)). Lead has no taste, so a taste neither shows nor rules it out.
