Perfluorooctanesulfonic acid
6.1ng/L
Each block = 4.0 ng/L federal MCL (2024)
Short answer: Two PFAS, PFOA and PFOS, are above their federal limits (2024 limits that water systems have until at least 2029 to meet); a past health-based violation (E. coli) is on record. Fort Oglethorpe serves 8,313 residents.

FORT OGLETHORPE (EPA PWSID GA0470001) delivers surface water to 8,313 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. Water hardness and disinfectant type are pending the utility's own annual report.
1health-based violation in the last 10 years
From EPA SDWIS. Counted once per contaminant per year, as in the Track record score.
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.
Every filing is listed; the Track record score counts at most one per contaminant per year.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Fort Oglethorpe, PFOS 6.1 ng/L and PFOA 4.5 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing; one health-based violation is on record (E. coli). FORT OGLETHORPE (PWSID GA0470001) 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.
FORT OGLETHORPE (PWS ID GA0470001) is the public water system on record for Fort Oglethorpe, Georgia, serving about 8,313 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2025-02-10 to 2025-11-04), PFOS was measured at 6.1 ng/L against a 4 ng/L federal limit and PFOA was measured at 4.5 ng/L against a 4 ng/L federal limit. PFBS (20 ng/L, below the 2,000 ng/L EPA health advisory) was also detected. PFBA (9.4 ng/L) and PFPeA (3.3 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.
Lead is not in Fort Oglethorpe'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.
The federal SDWIS record lists a health-based violation for FORT OGLETHORPE within about the last ten years: E. coli (2016). The findings above show each one's status.
PurityMap's current record for Fort Oglethorpe holds 32 findings: 3 above a reference, 1 detected within the reference, 2 detected with no limit and 26 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
