Ijamsville Infrastructure Age

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 Ijamsville, the median build year of 1999 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Ijamsville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Ijamsville: 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.
When older housing represents 43% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Ijamsville address.
