New Orleans has a lead crisis that most residents don't know about — and a four-month investigative series by Verite News, published February 20, 2026, has put the numbers in stark terms for the first time.
Between September 2022 and May 2025, the Sewerage and Water Board of New Orleans (SWBNO) conducted a free home water testing program. About 70% of the more than 1,100 participating households had lead detected in their water. Nearly every home with detectable lead exceeded the American Academy of Pediatrics' recommended limit of 1 ppb. The worst test recorded lead 100 times the federal action level of 15 ppb.
Construction to replace lead pipes citywide is not expected to begin until late 2027 — a one-year delay from previous projections, due to a procurement dispute at the SWBNO.
The Scale of the Problem
The SWBNO is one of the oldest water systems on the Gulf Coast. The city's water infrastructure includes pipes more than 100 years old, and the system has historically lacked a comprehensive lead pipe inventory. The utility now predicts that 50–60% of its 150,000 metered service lines will need at least partial replacement.
To understand the scale: Chicago — one of the cities most prominently associated with the US lead pipe crisis — has approximately 400,000 lead service lines in a city of 2.7 million. New Orleans, with a population under 380,000, faces a comparable proportional challenge in a much smaller and financially weaker city.
The testing data: The SWBNO's first free testing program isn't a scientific sample — participants were self-selected, and the program was promoted in neighborhoods more likely to have lead lines. But it's the most complete recent snapshot available, and the results are alarming. One block in the Upper Ninth Ward had lead detected in seven of eight households tested.
Why Replacement Is Delayed
The SWBNO has been attempting to hire a project management firm to run the lead pipe replacement program. The process has been derailed by a procurement dispute:
- The selection committee awarded a contract to engineering firm CDM Smith
- A competing bidder, EquiFlow NOLA, protested the decision
- The utility's hearing examiner rejected the protest in September 2025
- SWBNO Executive Director Randy Hayman overruled the hearing examiner in December 2025 and restarted the procurement process
The utility is now accepting new bids. Deputy General Superintendent Rebecca Johnsey said they'll try to shorten the procurement timeline to award a contract by end of 2026 and begin construction in late 2027.
The funding complication: The 2021 Bipartisan Infrastructure Law dedicated $15 billion for lead pipe replacement nationally. That funding ends in 2026, and Congress has already redirected $125 million of the remaining pool to other purposes. Future federal funding for lead replacement is uncertain under the current administration — a particular concern for New Orleans, where local resources are limited.
What's been done so far: As of December 2025, the SWBNO had replaced lines serving 14 schools and 144 residences, plus conducted more than 350 service line inspections. This represents a small fraction of what's needed.
The Climate Wildcard: Saltwater and Corroding Pipes
New Orleans has a second lead-related threat that is unique among major US cities: saltwater intrusion in the Mississippi River.
In 2023, a saltwater wedge from the Gulf of Mexico pushed unusually far upriver during a drought year, threatening to reach New Orleans' Carrollton Water Treatment Plant. The Army Corps of Engineers built an emergency underwater silt sill to slow the intrusion. The water supply was ultimately protected, but the near-miss revealed a structural vulnerability.
The connection to lead: saltwater corrodes pipes faster than freshwater. If saltwater reaches New Orleans' distribution system in a future event, it would accelerate corrosion of lead pipes and dramatically increase lead leaching into the water. Climate change-driven drought on the Mississippi increases the frequency of such events.
This is why lead pipe replacement in New Orleans isn't just an aging infrastructure problem — it's also a climate resilience problem.
What's Currently in New Orleans Tap Water
Lead: Active Crisis
The Carrollton Water Treatment Plant produces lead-free treated water. Lead enters the water supply at the service line and interior plumbing level. Given that 50–60% of service lines are predicted to need replacement, and that 70% of tested homes showed lead, this is an active and ongoing exposure risk for a significant share of New Orleans residents.
Highest-risk populations:
- Children under 6 (no safe level of lead exposure exists for developing brains)
- Pregnant residents (lead in bones releases during pregnancy and can affect fetal development)
- Residents of the oldest neighborhoods with century-old pipe infrastructure: Uptown, Garden District, Bywater, Marigny, Ninth Ward, Mid-City, Treme
- Anyone who has not tested their water
PFAS: Present in Mississippi River Watershed
The Mississippi River drains 41% of the contiguous United States. Industrial, agricultural, and military PFAS sources throughout this massive watershed contribute PFAS to the river. The Carrollton Plant's treatment process does not currently include specialized PFAS removal (granular activated carbon at the plant level or RO). EWG data shows PFAS detected in New Orleans water at levels above their health guidelines.
PFAS are a secondary concern relative to lead in New Orleans — the acute lead risk dominates — but residents who want comprehensive protection should use RO filtration that removes both.
Disinfection Byproducts: Elevated
The Mississippi River carries high organic loads from agricultural and urban runoff throughout its basin. Chlorine disinfection at the Carrollton Plant produces TTHMs and HAAs. EWG data shows haloacetic acids at levels hundreds of times above their health guideline. These are within federal MCLs but among the higher levels nationally for a major city.
Arsenic: Above EWG Guideline
EWG data shows arsenic levels above their health guideline, though below the federal 10 ppb MCL. Source is geological — the Mississippi floodplain's geological context.
What New Orleans Residents Should Do Right Now
This is one of the clearest cases where filtration is not optional. With 70% of tested homes showing lead, and pipe replacement not beginning until at least late 2027, New Orleans residents — particularly those with children, pregnant household members, or who live in older neighborhoods — should not wait.
Step 1: Get Tested
The SWBNO's free water testing program is still ongoing. Residents can request a testing kit. This tells you your current lead level and helps the utility map the problem.
Additionally, the SWBNO provides a free lead-filtering water pitcher to residents with confirmed lead waterlines (contact SWBNO to request one). However, replacement filters after the first six months are not provided for free.

Step 2: Use a Certified Filter
While waiting for pipe replacement, a filter certified for lead reduction is the most practical protection. Look specifically for NSF/ANSI Standard 53 certification listing lead reduction.
Best options for New Orleans:
Pitcher filter (most accessible, free option through SWBNO):
- Clearly Filtered Pitcher (~$90) — independently certified for lead, PFAS, DBPs, and 360+ contaminants; best non-RO pitcher available
- Brita Elite (~$40) — NSF 53 certified for lead (blue Elite filter only); accessible budget option
- SWBNO's free pitcher (request through the utility) — NSF certified for lead; free for residents with confirmed lead lines
Under-sink filter (for higher-risk situations with children/pregnancy):
- Frizzlife SK99 (~$90) — NSF 53 certified for lead, no drilling required
- PUR PLUS Faucet Filter (~$35) — NSF 53 certified, installs in minutes; lowest-barrier option
Under-sink RO (comprehensive protection — lead + PFAS + DBPs + arsenic):
- APEC ROES-50 (~$215) — NSF 58 certified; removes lead to non-detectable levels plus PFAS, DBPs, and arsenic
- Bluevua RO100ROPOT-LITE Countertop RO (~$299) — no-installation countertop RO; good for renters in New Orleans' large rental market
Step 3: Use Cold Water and Run Before Use
- Never use hot tap water for drinking, cooking, or baby formula (lead concentrates in hot water)
- Run cold water for 2–3 minutes before using for drinking or cooking, especially first thing in the morning or after the water has been sitting unused
The Environmental Justice Context
New Orleans is a majority-Black city with a high poverty rate, and the neighborhoods with the oldest housing and worst lead infrastructure — Upper Ninth Ward, Treme, Seventh Ward, Central City — are predominantly low-income communities of color. Lead exposure doesn't affect all neighborhoods equally: old infrastructure concentrates in areas that faced decades of disinvestment.
Dr. Adrienne Katner, Associate Professor at LSU-Health School of Public Health, who assisted with the Verite News investigation, noted that the SWBNO's historic failure to notify residents of lead risks has left many people exposed without knowing it.
The Water Collaborative of Greater New Orleans has emphasized "structured urgency" — the need for speed in replacement while ensuring equity in prioritization.
The Bottom Line for New Orleans Residents
New Orleans' lead problem is serious, active, and affecting a majority of households in older parts of the city. Pipe replacement won't begin citywide until late 2027 at the earliest. In the meantime, filtered water for drinking, cooking, and baby formula is not a precaution — it's a necessity.
Request a free test kit from the SWBNO. Get the free pitcher if you have confirmed lead lines. For households with children or pregnant residents, invest in under-sink filtration or RO.
