Lead Exposure Risk for Children in Farmington
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.
Lead risk in Farmington appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.

Flood & Climate Risk in Farmington
FEMA data shows 67% of Farmington's ZIP codes mapped into designated flood zones, paired with an NFIP record of 111 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Farmington has a moderate flood history with 111 FEMA claims averaging $10,416 per payout. 67% 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>$1,500</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.
