Questions
Frequently asked questions
Is Croydon tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Croydon, PFOA 4.5 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing. AQUA PA BRISTOL (PWSID PA1090001) has a Purity Score of 76/100 (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 Croydon?
AQUA PA BRISTOL (PWS ID PA1090001) is the public water system on record for Croydon, Pennsylvania, serving about 28,727 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Croydon get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Croydon's water?
Yes. In EPA's UCMR 5 testing (2024-02-08 to 2024-10-30), PFOA was measured at 4.5 ng/L against a 4 ng/L federal limit. PFHxA (4.4 ng/L, below the 400,000 ng/L state limit) was also detected. PFPeA (4.5 ng/L) was also detected; it has 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 Croydon's tap water?
Lead is not in Croydon'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 Croydon water report show?
PurityMap's current record for Croydon holds 31 findings: 1 above a reference, 1 detected within the reference, 1 detected with no limit and 28 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
