Perfluorooctanoic acid
5.5ng/L
Each block = 4.0 ng/L federal MCL (2024)
Short answer: PFOA is above its federal limit (a 2024 limit 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. Mount Dora, City of (2wps) serves 39,710 residents.
EPA lists this system for the city. Your water bill or annual water quality report names your actual supplier.

MOUNT DORA, CITY OF (2WPS) (EPA PWSID FL3350858) delivers groundwater to 39,710 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.
Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
PFOA 5.5 ng/L, above the 4 ng/L limit (+4 more PFAS detected)
225 galvanized lines to replace
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

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 Mount Dora, PFOA 5.5 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing. MOUNT DORA, CITY OF (2WPS) (PWSID FL3350858) has a Purity Score of 70/100 (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.
MOUNT DORA, CITY OF (2WPS) (PWS ID FL3350858) is the public water system on record for Mount Dora, Florida, serving about 39,710 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 (2024-09-25 to 2026-01-13), PFOA was measured at 5.5 ng/L against a 4 ng/L federal limit. PFBS (4.2 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (3.4 ng/L, below the 400,000 ng/L state limit) and PFHxS (5.2 ng/L, below the 10 ng/L federal limit) were also detected. PFPeA (5.6 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.
Lead is not in Mount Dora'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 Mount Dora holds 31 findings: 1 above a reference, 3 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.
