How Old Is Wilmer's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Wilmer, the median build year of 1997 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Wilmer were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Wilmer: Remediation Cost in Perspective
In Wilmer, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Wilmer are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 14% below the Alabama average.
Protecting Children from Lead in Wilmer
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 stock in Wilmer represents 38% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

Climate-Related Water Risk for Wilmer
Measured across the NFIP's multi-decade tracking period, Wilmer shows a moderate flood record — 7 claims and 100% of ZIP codes carrying FEMA flood zone status. For water quality, that combination matters because flood events at this frequency can periodically stress infrastructure: treatment plants, private wells, and distribution systems all face elevated risk during significant flooding.
Wilmer has a moderate flood history with 7 FEMA claims averaging $6,761 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.
