Housing Age Profile
Some cities skew heavily toward one construction era; Saltillo does not. The median build year of 1998 reflects a housing stock where older and newer homes share the market in meaningful proportions. That mixed profile means the city carries moderate aggregate plumbing-era risk - with older homes, particularly those built before 1986, representing the portion of the stock where lead-soldered joints may still be present.
Most homes in Saltillo were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Saltillo: 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.
Before the federal solder ban, lead solder was a routine plumbing material, and 44% of the Saltillo inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.
