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

Andover: Flood History & Water Damage Risk
Within the NFIP's national dataset, Andover falls in moderate-exposure territory — 210 documented incidents spanning multiple decades, with 20% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Andover has a moderate flood history with 210 FEMA claims averaging $38,947 per payout. 20% 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>$1,960</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.
