Questions
Frequently asked questions
Is Broken Arrow tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Broken Arrow, PFOS 51.3 ng/L (limit 4 ng/L) and PFHxS 15.2 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing; the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level. BROKEN ARROW MUNICIPAL AUTHORITY (PWSID OK1021508) has a Purity Score of 55/100 (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 Broken Arrow?
BROKEN ARROW MUNICIPAL AUTHORITY (PWS ID OK1021508) is the public water system on record for Broken Arrow, Oklahoma, serving about 116,330 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Broken Arrow get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Broken Arrow's water?
Yes. In EPA's UCMR 5 testing (2023-02-06 to 2023-12-05), PFOS was measured at 51.3 ng/L against a 4 ng/L federal limit and PFHxS was measured at 15.2 ng/L against a 10 ng/L federal limit. PFBS (4.5 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (6.9 ng/L, below the 400,000 ng/L state limit) were also detected. PFBA (6.4 ng/L) and PFPeA (6.5 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 Broken Arrow's tap water?
BROKEN ARROW MUNICIPAL AUTHORITY'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.
What does the latest Broken Arrow water report show?
PurityMap's current record for Broken Arrow holds 31 findings: 2 above a reference, 3 detected within the reference, 2 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.
