Questions

Frequently asked questions

Is Greenwood tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Greenwood, HFPO-DA (GenX) 91.1 ng/L (limit 10 ng/L), PFOS 8.7 ng/L (limit 4 ng/L) and PFOA 5.9 ng/L (limit 4 ng/L) were measured above their limits in EPA's 2024 testing; the lead 90th-percentile result was 4 µg/L against the 15 µg/L action level. GREENWOOD CPW (2410001) (PWSID SC2410001) has a Purity Score of 52/100 (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 Greenwood?

GREENWOOD CPW (2410001) (PWS ID SC2410001) is the public water system on record for Greenwood, South Carolina, serving about 52,022 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Greenwood get its drinking water?

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

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

Yes. In EPA's UCMR 5 testing (2025-03-04 to 2025-12-03), HFPO-DA (GenX) was measured at 91.1 ng/L against a 10 ng/L federal limit, PFOS was measured at 8.7 ng/L against a 4 ng/L federal limit and PFOA was measured at 5.9 ng/L against a 4 ng/L federal limit. PFBS (4.6 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (6.1 ng/L, below the 400,000 ng/L state limit) were also detected. PFPeA (7 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 Greenwood's tap water?

GREENWOOD CPW (2410001)'s most recent lead 90th-percentile result (2021–2023) was 4 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

What does the latest Greenwood water report show?

PurityMap's current record for Greenwood holds 31 findings: 3 above a reference, 3 detected within the reference, 1 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.
