Housing Age Profile
Although a small portion of Rollinsville's homes predate 1986, the median build year of 1993 indicates the majority of the city's residential plumbing was installed after lead solder was banned — which tends to reduce the plumbing-related component of lead exposure at the household level.
Most homes in Rollinsville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Flood & Climate Risk in Rollinsville
Flood risk in Rollinsville occupies the middle ground: 2 NFIP claims and 100% of local ZIP codes within FEMA flood zones. At that level, the risk pathways connecting flooding to water quality — treatment system stress, well infiltration, distribution backflow — become relevant considerations during significant flood events, even if day-to-day water quality is unaffected by flood history.
Rollinsville has a moderate flood history with 2 FEMA claims averaging $98 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>$2,400</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.
