Ask your utility first

Find out if your building has a lead service line

Water utilities keep an inventory of service-line materials. Ask West Jefferson Waterworks District 2 whether your address is on it before you replace pipes.

Local help

Think your plumbing may be adding lead?

Call to be connected with a local plumbing provider about lead service lines, repiping or fixture replacement.

Is this right for my home?

Choose your situation

Your situation
Your path: I live in an older buildingLead from plumbing is the main question

Older buildings may have lead service lines, solder or fixtures. Jefferson Parish (West Bank)’s record shows lead at 2.374 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.

Look forLead reduction: NSF/ANSI 53 (lead)
How to test your tap →
Your path: I care about PFASCheck what was tested

1 of 29 PFAS tested was detected in Jefferson Parish (West Bank)’s record (PFBA 6.5 ng/L). If PFAS matters to you, a filter certification names each compound it covers.

Look forNSF/ANSI 53 or 58, with each compound you care about named on the listing

Your path: My water tastes of chlorineThe disinfectant is not in this record

Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.

Look forNSF/ANSI 42 (chlorine taste and odor)

Your path: I have scale or hard waterJefferson Parish (West Bank) water is hard (7.9 gpg)

Scale is a comfort and appliance issue, not a health one.

Your path: I want the broadest reductionReverse osmosis at one tap

Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.

Is Jefferson Parish (West Bank) tap water safe to drink?

For Jefferson Parish (West Bank), PFBA 6.5 ng/L was detected, with no federal or state limit; the lead 90th-percentile result was 2.37 µg/L against the 15 µg/L action level. W JEFFERSON WW DISTRICT 2 (PWSID LA1051004) has a Purity Score of 96/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured.

Methodology: how we analyze water. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.

Methodology

How PurityMap reads Jefferson Parish (West Bank)’s water

  1. 01Source data

    EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.

  2. 02Normalize

    Units converted to one basis; a non-detect kept distinct from zero.

  3. 03Classify

    Each result tagged by reference type: MCL, action level, screening level or aesthetic.

  4. 04Compare to the named reference

    Every value sits against its own reference, never a blended one.

  5. 05Score

    Measured subjects summarised at the water-system level; an open health-based violation caps the score.

  6. 06Match treatment

    Treatment is matched to what was found; a product is called certified only when its current certification names it.

What the Purity Score means: a summary of this water system’s published record, capped while a health-based violation is open. It is not a test of any tap. W JEFFERSON WW DISTRICT 2 · PWSID LA1051004 · Purity Score 96/100 (Excellent) · Confidence: moderate · Assessed at the water-system level
