Housing Age Profile
The median home in Dassel was built in 1988 — a figure that places most of the city's residential stock in the era when lead solder was still standard in copper plumbing. Homes built before 1986 may have lead-soldered joints; those built before 1970 face the additional possibility of lead pipes in the service line itself.
Over half of homes in Dassel were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Dassel Homeowners
At current valuations, Dassel sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Dassel are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 20% above the Minnesota average.
Lead Exposure Risk for Children in Dassel
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.
Older interior plumbing shapes the local picture: 55% of Dassel homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.
