How Old Is Garrison's Housing Stock?
With 45% 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 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Garrison, the median build year of 1983 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Garrison were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Garrison: Remediation Cost in Perspective
What does remediation cost in financial context for Garrison homeowners? Proportionally very little — the equity share here is low, and addressing documented issues is a manageable planning question rather than a material financial burden.
Remediation costs in Garrison are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 8% above the Missouri average.
Protecting Children from Lead in Garrison
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 45% of the Garrison 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.
