How Old Is Suncook's Housing Stock?
With 73% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Reading the housing age data for Suncook — median build year 1976 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Suncook were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Suncook: Remediation Cost in Perspective
Low proportionality — that's the Suncook picture when remediation costs are placed against typical home equity.
Remediation costs in Suncook are relatively low compared to home values. The $1,750–$4,700 estimated range is a small fraction of median property value. Home values are 15% below the New Hampshire average.
Protecting Children from Lead in Suncook
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 73% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Suncook.

Climate-Related Water Risk for Suncook
FEMA data shows 100% of Suncook's ZIP codes mapped into designated flood zones, paired with an NFIP record of 139 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Suncook has a moderate flood history with 139 FEMA claims averaging $20,551 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>$3,100</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.
