PA AMER WATER CO NEW CASTLE (EPA PWSID PA6370034) delivers surface water to 43,279 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.
1health-based violation in the last 10 years
From EPA SDWIS. Counted once per contaminant per year, as in the Track record score.
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.
Every filing is listed; the Track record score counts at most one per contaminant per year.

Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 2 µg/L, below the 15 µg/L action level
PFHxA 3 ng/L, below the 400000 ng/L state limit (+2 more PFAS detected)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Screening: quick check, not lab-grade
Safe Home (EnviroTestKits)
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 New Castle, PFAS were detected below their limits, and PFBA 5.9 ng/L and PFPeA 3.1 ng/L with no federal or state limit; the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level; one health-based violation is on record (E. coli). PA AMER WATER CO NEW CASTLE (PWSID PA6370034) has a Purity Score of 97/100 (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.
PA AMER WATER CO NEW CASTLE (PWS ID PA6370034) is the public water system on record for New Castle, Pennsylvania, serving about 43,279 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
In EPA's UCMR 5 testing (2024-02-05 to 2024-11-04), PFHxA was detected at 3 ng/L, below the 400,000 ng/L state limit. PFBA (5.9 ng/L) and PFPeA (3.1 ng/L) were also detected; they have no federal or state limit.
PA AMER WATER CO NEW CASTLE's most recent lead 90th-percentile result (2025) was 2 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.
The federal SDWIS record lists a health-based violation for PA AMER WATER CO NEW CASTLE within about the last ten years: E. coli (2017). The findings above show each one's status.
PurityMap's current record for New Castle holds 32 findings: 1 above a reference, 2 detected within the reference, 2 detected with no limit and 27 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
