Housing Age Profile

Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Callaway, the median build year of 1997 indicates that plumbing age is a material factor in local lead risk - with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.

Est. Remediation
$2,200
Remediation as % of home value 0.6%

Lead Exposure Risk for Children in Callaway

34%
Homes Built Before 1986

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.

In recent monitoring under the Lead and Copper Rule, citywide samples for Callaway have approached or crossed the regulatory action level on multiple occasions. Combined with 34% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
