Perfluorooctanesulfonic acid
20.7ng/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); 4 more are detected with no federal limit, and everything else measured is within its reference or not detected. BCWWS 1a serves 75,305 residents.

BCWWS 1A (EPA PWSID FL4060167) delivers groundwater to 75,305 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.

Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
PFOS 20.7 ng/L, above the 4 ng/L limit (+8 more PFAS detected)
lead 1.6 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.

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 Lauderdale Lakes, PFOS 20.7 ng/L and PFOA 7.2 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 1.6 µg/L against the 15 µg/L action level. BCWWS 1A (PWSID FL4060167) 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.
BCWWS 1A (PWS ID FL4060167) is the public water system on record for Lauderdale Lakes, Florida, serving about 75,305 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 (2024-04-04 to 2024-10-22), PFOS was measured at 20.7 ng/L against a 4 ng/L federal limit and PFOA was measured at 7.2 ng/L against a 4 ng/L federal limit. PFBS (6 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (10.6 ng/L, below the 400,000 ng/L state limit) and PFHxS (3.4 ng/L, below the 10 ng/L federal limit) were also detected. 6:2 FTS (5.5 ng/L), PFBA (10.1 ng/L), PFHpA (4.9 ng/L) and PFPeA (14.6 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.
BCWWS 1A's most recent lead 90th-percentile result (2025) was 1.6 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 Lauderdale Lakes holds 31 findings: 2 above a reference, 4 detected within the reference, 4 detected with no limit and 21 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
