Housing & Infrastructure in Chauvin
With 75% 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
Plumbing risk in older housing is defined by two eras: the pre-1970 period when lead pipes were commonly used for service lines, and the 1970-to-1986 period when lead solder remained standard in copper plumbing until the federal ban. Chauvin's median build year of 1976 lands in a range where both eras are heavily represented in the housing stock. That creates an elevated aggregate environment for plumbing-related lead exposure — one that city-level water quality averages don't capture, because the risk sits inside individual properties rather than in the distribution system.
Over half of homes in Chauvin were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Chauvin Homeowners
The equity impact of remediation in Chauvin sits at a moderate level — real enough to plan for, within reach for most.
Remediation costs are moderate relative to home values in Chauvin. The estimated $1,500–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 32% below the Louisiana average.
Lead Exposure Risk for Children in Chauvin
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.
Older interior plumbing shapes the local picture: 75% of Chauvin homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.

Flood & Climate Risk in Chauvin
Flood claims in Chauvin number 3632 under the NFIP, and 100% of ZIP codes fall within FEMA-designated zones — together reflecting a community where flooding is a recurring, significant feature of the local risk environment with direct implications for periodic water supply safety.
Chauvin has a significant flood history with 3,632 FEMA flood insurance claims on record, averaging $25,034 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>$2,300</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.
