Questions

Frequently asked questions

Is Guntersville tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Guntersville, PFOA 6.8 ng/L and PFOS 4.8 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing. GUNTERSVILLE WW & SB (PWSID AL0000943) has a Purity Score of 64/100 (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 Guntersville?

GUNTERSVILLE WW & SB (PWS ID AL0000943) is the public water system on record for Guntersville, Alabama, serving about 13,374 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Guntersville get its drinking water?

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

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

Yes. In EPA's UCMR 5 testing (2023-12-13 to 2024-09-16), PFOA was measured at 6.8 ng/L against a 4 ng/L federal limit and PFOS was measured at 4.8 ng/L against a 4 ng/L federal limit. PFBS (3.3 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (8.7 ng/L, below the 400,000 ng/L state limit) were also detected. PFBA (12 ng/L), PFHpA (3.9 ng/L) and PFPeA (8.7 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 Guntersville's tap water?

Lead is not in Guntersville'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 Guntersville water report show?

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