From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.

Frequently asked questions
Is York tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For York, PFAS were detected below their limits, and PFPeA 3.9 ng/L with no federal or state limit. YORK CITY OF (SC4610001) (PWSID SC4610001) has a Purity Score of 100/100 (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 York?
YORK CITY OF (SC4610001) (PWS ID SC4610001) is the public water system on record for York, South Carolina, serving about 11,137 people. Confirm the utility on your water bill before acting on a specific finding.
Where does York get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in York's water?
In EPA's UCMR 5 testing (2024-04-10 to 2024-11-20), PFHxA was detected at 3.4 ng/L, below the 400,000 ng/L state limit. PFPeA (3.9 ng/L) was also detected; it has no federal or state limit.
Is there lead in York's tap water?
Lead is not in York'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.
