Union: Lead Risk & Vulnerable Populations

19%
Homes Built Before 1986

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.

In Union, the older-stock footprint runs at 19% — a contained slice — and aggregate utility readings land safely under the EPA action mark. That keeps lead off the local priority list, with a one-faucet draw remaining the only direct read on a specific address.

Union: Flood History & Water Damage Risk

Measured across the NFIP's multi-decade tracking period, Union shows a moderate flood record — 12 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.

Est. Claims/Year

Union has a moderate flood history with 12 FEMA claims averaging $12,156 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>$1,600</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.
