How Old Is Cornish's Housing Stock?
With 66% 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
Pre-1986 plumbing is not a rare legacy case in Cornish — it's the dominant profile. The median build year of 1959 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Cornish were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cornish: Remediation Cost in Perspective
Because property values in Cornish comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Cornish 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 Utah average.
Protecting Children from Lead in Cornish
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: 66% of Cornish 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.
