How Old Is Mendon's Housing Stock?
With 58% 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
For residents trying to assess tap water risk in Mendon, the median build year of 1989 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Mendon were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Mendon: Remediation Cost in Perspective
In Mendon, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Mendon are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 18% below the New York average.
Protecting Children from Lead in Mendon
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 solder ban, lead solder was a routine plumbing material, and 58% of the Mendon inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Climate-Related Water Risk for Mendon
Flood exposure in Mendon is meaningful by NFIP measures — 12 claims on record and 100% of ZIP codes carrying FEMA flood zone designations. That level of activity makes flood history a relevant factor when evaluating local water quality over time.
Mendon has a moderate flood history with 12 FEMA claims averaging $6,634 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.
