How Old Is New London's Housing Stock?
With 51% 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
Plumbing risk in older housing is defined by two eras: the pre-1970 period when lead pipes were commonly used for service lines, and the 1970-to-1986 period when lead solder remained standard in copper plumbing until the federal ban. New London's median build year of 1984 lands in a range where both eras are heavily represented in the housing stock. That creates an elevated aggregate environment for plumbing-related lead exposure — one that city-level water quality averages don't capture, because the risk sits inside individual properties rather than in the distribution system.
Over half of homes in New London were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

New London: Remediation Cost in Perspective
In New London, the equity impact of remediation is proportionally small — not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in New London are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 25% above the Minnesota average.
Protecting Children from Lead in New London
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for New London have approached or crossed the regulatory action level on multiple occasions. Combined with 51% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

What You Can Do in New London

- Install a certified water filter. Filters rated for Total Trihalomethanes (TTHM) can reduce the most common contaminant found in New London's water.
- Check your home's plumbing. With 51% of homes built before 1986, lead solder is a real possibility.
