Edgerton: Lead Risk & Vulnerable Populations
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 60% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Edgerton.

Edgerton: Flood History & Water Damage Risk
FEMA data shows 100% of Edgerton's ZIP codes mapped into designated flood zones, paired with an NFIP record of 89 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Edgerton has a moderate flood history with 89 FEMA claims averaging $23,068 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>$3,300</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.
