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.
Source: U.S. Census Bureau American Community Survey (ACS).
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.

Historical Flood-Claim Evidence for Mendon
Historical NFIP data for Mendon contains 13 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $9,201. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$2,400</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
