SHILLINGTON MUNI AUTH (EPA PWSID PA3060067) delivers surface water to 13,300 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.
2health-based violations 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.
43 galvanized lines to replace
PFBS 4.3 ng/L, below the 2000 ng/L EPA health advisory (+2 more PFAS detected)
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 Shillington, PFAS were detected below their limits, and PFBA 6.6 ng/L and PFPeA 3.8 ng/L with no federal or state limit. SHILLINGTON MUNI AUTH (PWSID PA3060067) has a Purity Score of 96/100 (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.
SHILLINGTON MUNI AUTH (PWS ID PA3060067) is the public water system on record for Shillington, Pennsylvania, serving about 13,300 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 (2023-01-13 to 2023-11-20), PFBS was detected at 4.3 ng/L, below the 2,000 ng/L EPA health advisory. PFBA (6.6 ng/L) and PFPeA (3.8 ng/L) were also detected; they have no federal or state limit.
Lead is not in Shillington'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 Shillington 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.
