Perfluorooctanesulfonic acid
8.3ng/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. Pace Water System, Inc. serves 49,328 residents.

The bar is drawn in blocks of the 4.0 ng/L federal MCL (2024), so the length shows how far above it the result sits.

PACE WATER SYSTEM, INC. (EPA PWSID FL1570671) delivers groundwater to 49,328 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.
PFOS 8.3 ng/L, above the 4 ng/L limit (+1 more PFAS detected)
lead 2.6 µg/L, below the 15 µg/L action level
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 Pace, PFOS 8.3 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 2.6 µg/L against the 15 µg/L action level. PACE WATER SYSTEM, INC. (PWSID FL1570671) has a Purity Score of 54/100 (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.
PACE WATER SYSTEM, INC. (PWS ID FL1570671) is the public water system on record for Pace, Florida, serving about 49,328 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 (2023-11-01 to 2024-05-06), PFOS was measured at 8.3 ng/L against a 4 ng/L federal limit. PFHxS was detected below its limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
PACE WATER SYSTEM, INC.'s most recent lead 90th-percentile result (2023) was 2.6 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 Pace holds 31 findings: 1 above a reference, 2 detected within the reference and 28 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
