Questions

Frequently asked questions

Is Burlington tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Burlington, PFOS 17 ng/L and PFOA 13 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing; one health-based violation is on record (E. coli). BURLINGTON, CITY OF (PWSID NC0201010) has a Purity Score of 56/100 (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 Burlington?

BURLINGTON, CITY OF (PWS ID NC0201010) is the public water system on record for Burlington, North Carolina, serving about 61,365 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Burlington get its drinking water?

Surface water (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in Burlington's water?

Yes. In EPA's UCMR 5 testing (2024-07-12 to 2025-04-14), PFOS was measured at 17 ng/L against a 4 ng/L federal limit and PFOA was measured at 13 ng/L against a 4 ng/L federal limit. PFHxA (4.4 ng/L, below the 400,000 ng/L state limit) and PFHxS (3.2 ng/L, below the 10 ng/L federal limit) were also detected. 6:2 FTS (9.7 ng/L), PFHpA (4.2 ng/L) and PFPeA (4.1 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 Burlington's tap water?

Lead is not in Burlington'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.

Has Burlington's water system had violations?

The federal SDWIS record lists a health-based violation for BURLINGTON, CITY OF within about the last ten years: E. coli (2021). The findings above show each one's status.

What does the latest Burlington water report show?

PurityMap's current record for Burlington holds 32 findings: 3 above a reference, 2 detected within the reference, 3 detected with no limit and 24 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
