Housing Age Profile
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Crumpton, the median build year of 2008 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Crumpton were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Crumpton
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.
Although citywide aggregate readings pass cleanly and just 30% of Crumpton housing comes from the pre-rule era, the difference between what utilities sample and what arrives at one specific faucet remains a structural feature of how monitoring works. Households with kids in the home can find a certified lead-removal filter and a draw-test kit through retailer-verified channels. That step is independent of system-level data.

Flood & Climate Risk in Crumpton
Measured across the NFIP's multi-decade tracking period, Crumpton shows a moderate flood record — 2 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.
Crumpton has a moderate flood history with 2 FEMA claims averaging $26,021 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>$1,800</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.
