Arabi Infrastructure Age
With 82% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Reading the housing age data for Arabi — median build year 1966 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Arabi were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Arabi
In Arabi, the equity share of documented remediation is meaningful enough to move the household financial perspective from routine maintenance into deliberate budgeting territory — the cost-to-value ratio is moderate, and most homeowners benefit from mapping the full scope against available budgets before committing.
Remediation costs are moderate relative to home values in Arabi. The estimated $1,800–$4,000 range is manageable for most homeowners but still worth budgeting for. Home values are 25% above the Louisiana average.
Arabi: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 82% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Arabi.

Arabi: Flood History & Water Damage Risk
Decades of documented flood activity appear in Arabi's NFIP record — 4557 insurance claims filed and 100% of ZIP codes carrying FEMA flood designations. The scale of that record puts water infrastructure vulnerability from flooding into the concrete-risk category.
Arabi has a significant flood history with 4,557 FEMA flood insurance claims on record, averaging $72,942 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,500</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.

What You Can Do in Arabi
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 82% of homes built before 1986, lead solder is a real possibility.
