How Old Is Fitzwilliam's Housing Stock?
With 69% 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.

Housing Age Profile
Decades of residential development in Fitzwilliam took place before the two main regulatory milestones that reduced plumbing-era lead risk: the phase-out of lead pipes before 1970, and the federal ban on lead solder in 1986. With a median build year of 1977, the housing stock here is anchored in that earlier period. The distinction between pre-1970 and 1970-to-1986 construction matters: the oldest homes may have lead pipes in the service line and lead solder in the copper joints, while the 1970-to-1986 tier still carries the solder risk even after lead pipes became less common. Together, these two risk layers affect a majority of the residential properties in the city — a fact the aggregate water quality data doesn't directly reveal.
Over half of homes in Fitzwilliam were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Fitzwilliam: Remediation Cost in Perspective
Cost-to-value data for Fitzwilliam produces a high remediation-share classification — the equity impact here is elevated, placing this market in the tier where financial preparation is a meaningful factor in how homeowners approach documented issues.
At 2.1% of home value, remediation costs in Fitzwilliam represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $3,560–$8,120. Home values here are 25% below the New Hampshire average.
Protecting Children from Lead in Fitzwilliam
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.
Before the federal action against lead-bearing solder, that material was routinely permitted in new plumbing — and 69% of Fitzwilliam housing dates from that earlier era. Citywide utility samples have also moved past the regulatory action level. Two independent indicators are aligned here: a majority of buildings carry pre-rule interior lines, while system-level concentrations sit beyond the federal benchmark. Households with kids or pregnant residents can find an in-home test and a certified lead-removal filter through certified retail channels.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

Climate-Related Water Risk for Fitzwilliam
Fitzwilliam's flood exposure sits in the moderate range: 2 NFIP claims on record and 100% of ZIP codes within FEMA-designated flood zones. Residents with private wells or older infrastructure have reasonable grounds to factor flood timing into their water quality awareness.
Fitzwilliam has a moderate flood history with 2 FEMA claims averaging $3,019 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>$5,740</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.

What You Can Do in Fitzwilliam
