PA AMERICAN COATESVILLE (EPA PWSID PA1150106) delivers surface water to 36,960 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.
lead 2 µg/L, below the 15 µg/L action level (detected below the limit); 63 lead service lines; 219 galvanized lines to replace (context, not a tap measurement)
PFBA 5.5 ng/L detected (no federal or state limit) (+1 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 Coatesville, PFBA 5.5 ng/L and PFPeA 3.2 ng/L were detected, with no federal or state limit; the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level. PA AMERICAN COATESVILLE (PWSID PA1150106) has a Purity Score of 98/100 (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 AMERICAN COATESVILLE (PWS ID PA1150106) is the public water system on record for Coatesville, Pennsylvania, serving about 36,960 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 (2024-05-02 to 2025-02-03), PFBA was detected at 5.5 ng/L and PFPeA was detected at 3.2 ng/L. They have no federal or state limit, so PurityMap shows them without grading them. No PFAS with a limit was detected.
PA AMERICAN COATESVILLE'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.
PurityMap's current record for Coatesville holds 31 findings: 1 detected within the reference, 2 detected with no limit and 28 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
