Perfluorooctanoic acid
24.4ng/L
Each block = 4.0 ng/L federal MCL (2024)
Short answer: Two PFAS, PFNA and PFOA, are above their federal limits (2024 limits that water systems have until at least 2029 to meet); 5 more are detected with no federal limit, and everything else measured is within its reference or not detected. Veolia Water Delaware, Inc serves 100,495 residents.

VEOLIA WATER DELAWARE, INC (EPA PWSID DE0000564) delivers surface water to 100,495 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 24.4 ng/L, above the 4 ng/L limit (+8 more PFAS detected)
lead 2 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 Brookside, PFOA 24.4 ng/L (limit 4 ng/L) and PFNA 11.6 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing; the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level. VEOLIA WATER DELAWARE, INC (PWSID DE0000564) has a Purity Score of 55/100 (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.
VEOLIA WATER DELAWARE, INC (PWS ID DE0000564) is the public water system on record for Brookside, Delaware, serving about 100,495 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2023-02-08 to 2023-12-11), PFOA was measured at 24.4 ng/L against a 4 ng/L federal limit and PFNA was measured at 11.6 ng/L against a 10 ng/L federal limit. PFBS (3.7 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (31.7 ng/L, below the 400,000 ng/L state limit) were also detected. PFBA (40.6 ng/L), PFDA (4.7 ng/L), PFHpA (27.7 ng/L), PFPeA (32.1 ng/L) and PFUnA (3.8 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.
VEOLIA WATER DELAWARE, INC's most recent lead 90th-percentile result (2021–2023) was 2 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 Brookside holds 31 findings: 2 above a reference, 3 detected within the reference, 5 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.
