E JEFFERSON WW DISTRICT 1 (EPA PWSID LA1051001) delivers surface water to 275,163 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. The utility's 2025 CCR reports hard water.
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.
lead 2.65 µg/L, below the 15 µg/L action level
PFBA 6.6 ng/L detected (no federal or state limit)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Screening: quick check, not lab-grade
Varify
17 strip readings, including lead, chlorine, fluoride, iron and hardness, plus 2 coliform bacteria tests
What it can't tell you: Strip colors give rough ranges, not lab numbers, and it cannot detect PFAS or arsenic.
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 Metairie, PFBA 6.6 ng/L was detected, with no federal or state limit; the lead 90th-percentile result was 2.65 µg/L against the 15 µg/L action level. E JEFFERSON WW DISTRICT 1 (PWSID LA1051001) has a Purity Score of 97/100 (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.
E JEFFERSON WW DISTRICT 1 (PWS ID LA1051001) is the public water system on record for Metairie, Louisiana, serving about 275,163 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 (2023-07-18 to 2024-04-29), PFBA was detected at 6.6 ng/L. It has no federal or state limit, so PurityMap shows it without grading it. No PFAS with a limit was detected.
E JEFFERSON WW DISTRICT 1's most recent lead 90th-percentile result (2023–2025) was 2.65 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 Metairie holds 32 findings: 2 above a reference, 1 detected within the reference, 1 detected with no limit 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.
Metairie's water is recorded as 7.8 gpg, hard. Hardness is an aesthetic and plumbing characteristic, not a health-based limit.
