Housing Age Profile
What does a median build year of 1965 mean for water safety in Shelby? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used - making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Shelby were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Shelby: Remediation Cost in Perspective
Remediation costs in Shelby are small relative to typical property values - the cost-to-value ratio here is favorable.

Protecting Children from Lead in Shelby
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 78% of the Shelby inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.
