Perfluorooctanesulfonic acid
24.8ng/L
Each block = 4.0 ng/L federal MCL (2024)
Short answer: PFOS is above its federal limit (a 2024 limit that water systems have until at least 2029 to meet); everything else measured is within its reference or not detected. Apopka, City of (5 Wtps) serves 71,917 residents.

APOPKA, CITY OF (5 WTPS) (EPA PWSID FL3480200) delivers groundwater to 71,917 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.
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.
A tap test can confirm levels at your home before you choose treatment.
PFOS 24.8 ng/L, above the 4 ng/L limit (+1 more PFAS detected)
Each card names which Apopka findings its current certification covers, and which it doesn't.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Apopka, PFOS 24.8 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing. APOPKA, CITY OF (5 WTPS) (PWSID FL3480200) has a Purity Score of 57/100 (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.
APOPKA, CITY OF (5 WTPS) (PWS ID FL3480200) is the public water system on record for Apopka, Florida, serving about 71,917 people. Confirm the utility on your water bill before acting on a specific finding.
Groundwater (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2024-03-11 to 2024-09-19), PFOS was measured at 24.8 ng/L against a 4 ng/L federal limit. PFBS (3.8 ng/L, below the 2,000 ng/L EPA health advisory) was also detected. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Lead is not in Apopka'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.
PurityMap's current record for Apopka holds 31 findings: 1 above a reference, 1 detected within the reference and 29 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
