Questions

Frequently asked questions

Is North Attleborough tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For North Attleborough, PFOA 9 ng/L and PFOS 8 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 5.1 µg/L against the 15 µg/L action level. NORTH ATTLEBORO WATER DEPT (PWSID MA4211000) has a Purity Score of 51/100 (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.

Who provides tap water in North Attleborough?

NORTH ATTLEBORO WATER DEPT (PWS ID MA4211000) is the public water system on record for North Attleborough, Massachusetts, serving about 31,410 people. Confirm the utility on your water bill before acting on a specific finding.

Where does North Attleborough get its drinking water?

Groundwater (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in North Attleborough's water?

Yes. In EPA's UCMR 5 testing (2024-04-17 to 2024-10-17), PFOA was measured at 9 ng/L against a 4 ng/L federal limit and PFOS was measured at 8 ng/L against a 4 ng/L federal limit. PFBS (6 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (9 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 (6 ng/L), PFHpA (6 ng/L) and PFPeA (14 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.

Is there lead in North Attleborough's tap water?

NORTH ATTLEBORO WATER DEPT's most recent lead 90th-percentile result (2025) was 5.1 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.

What does the latest North Attleborough water report show?

PurityMap's current record for North Attleborough holds 31 findings: 2 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.
