Housing & Infrastructure in Grant
With 51% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Grant's median build year of 1985 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Grant 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 Grant Homeowners
Throughout Grant, fixing documented water and safety issues carries an equity weight that moves remediation out of routine planning territory and into structured financial decision-making.
At 2.1% of home value, remediation costs in Grant represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $800–$1,800. Home values here are 67% below the Louisiana average.
Lead Exposure Risk for Children in Grant
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 51% pre-rule share in Grant keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Flood & Climate Risk in Grant
Within the NFIP's national dataset, Grant falls in moderate-exposure territory — 6 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Grant has a moderate flood history with 6 FEMA claims averaging $10,809 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$1,200</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.
