Perfluorooctanesulfonic acid
6.9ng/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); 1 more is detected with no federal limit, and everything else measured is within its reference or not detected. Winter Springs, City of (3 Wps) serves 34,657 residents.

Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
PFOS 6.9 ng/L, above the 4 ng/L limit (+3 more PFAS detected)
lead 0.6 µg/L, below the 15 µg/L action level (detected below the limit); 127 galvanized lines to replace (context, not a tap measurement)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Winter Springs, PFOS 6.9 ng/L and PFOA 5 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 0.6 µg/L against the 15 µg/L action level. WINTER SPRINGS, CITY OF (3 WPS) (PWSID FL3590879) has a Purity Score of 60/100 (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.
WINTER SPRINGS, CITY OF (3 WPS) (PWS ID FL3590879) is the public water system on record for Winter Springs, Florida, serving about 34,657 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 (2024-10-17 to 2025-04-09), PFOS was measured at 6.9 ng/L against a 4 ng/L federal limit and PFOA was measured at 5 ng/L against a 4 ng/L federal limit. PFHxS was detected below its limit. PFPeA (4 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.
WINTER SPRINGS, CITY OF (3 WPS)'s most recent lead 90th-percentile result (2023) was 0.6 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.
PurityMap's current record for Winter Springs holds 31 findings: 2 above a reference, 2 detected within the reference, 1 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.
