Perfluorooctanoic acid
12ng/L
Each block = 4.0 ng/L federal MCL (2024)
Short answer: Two PFAS, PFOA and PFOS, are above their federal limits (2024 limits that water systems have until at least 2029 to meet); a past health-based violation (E. coli) is on record. Abington/Rockland Joint Wtr. Works serves 33,387 residents.

ABINGTON/ROCKLAND JOINT WTR. WORKS (EPA PWSID MA4001000) delivers surface water to 33,387 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.
PFOA 12 ng/L, above the 4 ng/L limit (+7 more PFAS detected)
lead 4 µg/L, below the 15 µg/L action level
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

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 Abington, PFOA 12 ng/L and PFOS 7 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 4 µg/L against the 15 µg/L action level; one health-based violation is on record (E. coli). ABINGTON/ROCKLAND JOINT WTR. WORKS (PWSID MA4001000) has a Purity Score of 48/100 (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.
ABINGTON/ROCKLAND JOINT WTR. WORKS (PWS ID MA4001000) is the public water system on record for Abington, Massachusetts, serving about 33,387 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 (2024-05-17 to 2025-02-06), PFOA was measured at 12 ng/L against a 4 ng/L federal limit and PFOS was measured at 7 ng/L against a 4 ng/L federal limit. PFBS (3 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (18 ng/L, below the 400,000 ng/L state limit) and PFHxS (4 ng/L, below the 10 ng/L federal limit) were also detected. PFBA (25 ng/L), PFHpA (8 ng/L) and PFPeA (32 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.
ABINGTON/ROCKLAND JOINT WTR. WORKS's most recent lead 90th-percentile result (2025) was 4 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 ABINGTON/ROCKLAND JOINT WTR. WORKS within about the last ten years: E. coli (2025). The findings above show each one's status.
PurityMap's current record for Abington holds 32 findings: 3 above a reference, 4 detected within the reference, 3 detected with no limit and 22 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
