Louisiana PWS
What this means for you
- Is it safe to drink right now?
- Based on the latest EPA data, Louisiana PWS has no unresolved health-based violations from the past year. Water that meets federal standards is generally considered safe to drink for most healthy people.
- Should I use a filter?
- It's worth considering. Louisiana PWS has a D because of its violation record over the past 5 years (9 health-based), even though nothing is flagged as unresolved in the last year. A filter matched to the contaminants in its violation history is a reasonable precaution.
- What kind of filter?
- See matched standards and product picks.
This is general information from public EPA data, not medical advice. Lead often comes from a home’s own pipes, so only a test of your tap can tell your exposure. If you are pregnant, caring for an infant, or have a weakened immune system, ask your doctor or health department.
PFAS (“forever chemicals”), EPA UCMR 5
| Chemical | Highest location average | Highest single sample | Federal limit | Detections/samples |
|---|---|---|---|---|
| PFBA | 4.1 ppt | 8.3 ppt | none | 2/4 |
5 PFAS tested and not detected
PFOS, PFOA, PFHxS, HFPO-DA, PFNA (4 samples each, below EPA minimum reporting levels).
Hazard Index (PFHxS, PFNA, GenX, PFBS): 0 (limit 1.0, proposed for repeal).
Averages are per sampling location across UCMR 5 samples (non-detects counted as 0), approximating the rule’s running annual average. Not an official compliance determination; PFOA/PFOS MCL compliance begins April 26, 2029.
Lithium (also tested in UCMR 5, not a PFAS; no federal limit): highest location average 2.3 ppb.
