COMMON QUESTIONS
Is New Orleans tap water safe to drink in 2025?
New Orleans water meets EPA legal standards, but meeting legal standards is not the same as being free of health concerns. EPA limits are set based on treatment feasibility, not always on what independent scientists consider safe. New Orleans has lead contamination which is a significant concern — certified filtration is strongly recommended.
Does New Orleans water have PFAS?
EPA UCMR5 monitoring data for New Orleans (water system LA1029011) is shown above. PFAS — sometimes called "forever chemicals" — are synthetic compounds that don't break down in the body. Only reverse osmosis systems or NSF 58-certified carbon block filters reliably remove PFAS from tap water. Standard pitcher filters do not remove PFAS.
Does New Orleans water have lead?
Lead in tap water almost always comes from the pipes inside your home or building, not the treatment plant. Homes built before 1986 in New Orleans are most at risk because they may have lead solder, brass fittings, or lead service lines. The EPA has no safe level for lead in children. An NSF/ANSI 53-certified filter or reverse osmosis system removes lead at the tap.
What water filter is best for New Orleans?
For New Orleans's water profile — lead contamination, disinfection byproducts — a reverse osmosis system addresses the widest range of contaminants. Under-sink RO (Waterdrop G3P800, Aquasana SmartFlow) is the gold standard for homeowners. Renters can use a countertop RO like the Waterdrop D4 — zero installation required. Clearly Filtered pitchers are the best non-RO option for PFAS and lead.
How do I get my New Orleans water tested?
For the most accurate results for your specific tap, use a certified mail-in lab test rather than relying on city-wide data. SimpleLab Tap Score tests for 100+ contaminants including PFAS, lead, arsenic, and nitrates. Results come with a detailed health assessment and filter recommendations. City-wide EPA data like what you see above is a strong baseline, but your home's plumbing can add contaminants after the water leaves the treatment plant.
As of October 2024, all US water utilities must publish a public inventory of their lead service lines — the pipes connecting the water main to your home. Even if your utility water tests clean at the treatment plant, lead can leach from these pipes into your tap. Homes built before 1986 are most at risk.

City-wide data is just the start. Enter your ZIP to see your exact water system's EPA report, PFAS levels, and violation history — then get the right filter for your home.
