Housing Age Profile
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Hartshorn's median build year of 1972 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Hartshorn 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 Hartshorn
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Hartshorn is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Hartshorn are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 32% above the Missouri average.
Hartshorn: 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.
Older stock in Hartshorn represents 60% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
