Track record

0health-based violations in the last 10 years

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.

Questions

Frequently asked questions

Is Cayce tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Cayce, PFOS 6.3 ng/L (limit 4 ng/L), PFOA 5.5 ng/L (limit 4 ng/L) and HFPO-DA (GenX) 11.6 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing. CAYCE CITY OF (SC3210003) (PWSID SC3210003) has a Purity Score of 66/100 (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 Cayce?

CAYCE CITY OF (SC3210003) (PWS ID SC3210003) is the public water system on record for Cayce, South Carolina, serving about 17,460 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Cayce get its drinking water?

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

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

Yes. In EPA's UCMR 5 testing (2025-02-24 to 2025-12-10), PFOS was measured at 6.3 ng/L against a 4 ng/L federal limit, PFOA was measured at 5.5 ng/L against a 4 ng/L federal limit and HFPO-DA (GenX) was measured at 11.6 ng/L against a 10 ng/L federal limit. PFBS (3.8 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (4.9 ng/L, below the 400,000 ng/L state limit) were also detected. PFPeA (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 Cayce's tap water?

Lead is not in Cayce'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 Cayce water report show?

PurityMap's current record for Cayce holds 31 findings: 3 above a reference, 2 detected within the reference, 1 detected with no limit and 25 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
