Housing Age Profile

With a median build year of 1997, Grand Bay's housing stock reflects a city built across multiple eras.

mg/L Avg Lead (Limit: 0.015)

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.

Routinely in Grand Bay, where 39% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

Flood damage can add significantly to the estimated <strong>$1,800</strong> remediation cost per household.
