How Old Is Hanover's Housing Stock?
With 74% 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
The lead that enters tap water in older homes often comes not from the municipal supply but from the home's own plumbing — from solder used in copper joints before the 1986 federal ban, or from lead pipes installed before 1970. In Hanover, where the median build year is 1975, these older materials are widespread. More than half the residential stock predates the 1986 solder ban, and a significant fraction predates 1970 as well. For residents in those homes, the city-wide water quality picture is a less relevant frame than the specific materials inside their own walls and under their own street.
Over half of homes in Hanover were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Hanover: Remediation Cost in Perspective
Within the Hanover market, estimated remediation claims a small portion of typical property equity — the financial burden is proportionally low.
Remediation costs in Hanover are relatively low compared to home values. The $150–$1,400 estimated range is a small fraction of median property value. Home values are 29% below the New Mexico average.
Protecting Children from Lead in Hanover
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.
Households with kids in the home — for whom CDC guidance places particular weight on minimizing exposure — face a specific local picture in Hanover. 74% of homes here come from the pre-rule era, and aggregate utility samples either approach or cross 0.015 mg/L. A baseline draw-test kit and certified lead-removal filtration are available via retailer networks for households confirming conditions at a specific tap.

What You Can Do in Hanover
- Test your water at home. City-level data shows averages — your tap may differ. Lead testing is especially recommended given the area's lead levels.
- Install a certified water filter. Filters rated for Contaminant 0700 can reduce the most common contaminant found in Hanover's water.
- Check your home's plumbing. With 74% of homes built before 1986, lead solder is a real possibility.
