Questions
Frequently asked questions
Is Henderson tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Henderson, PFOS 4.8 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing. HENDERSON-KERR LAKE REG WTR (PWSID NC0291010) has a Purity Score of 70/100 (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 Henderson?
HENDERSON-KERR LAKE REG WTR (PWS ID NC0291010) is the public water system on record for Henderson, North Carolina, serving about 14,937 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Henderson get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Henderson's water?
Yes. In EPA's UCMR 5 testing (2023-02-28 to 2024-02-20), PFOS was measured at 4.8 ng/L against a 4 ng/L federal limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Is there lead in Henderson's tap water?
Lead is not in Henderson'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.
What does the latest Henderson water report show?
PurityMap's current record for Henderson holds 31 findings: 1 above a reference and 30 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
