Carson City Infrastructure Age
With 72% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Carson City's median build year of 1964 places it squarely in that category.
Over half of homes in Carson City were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Carson City
At current valuations, Carson City sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Carson City are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 23% below the Michigan average.
Carson City: Lead Risk & Vulnerable Populations
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted — but 72% of the Carson City inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.
