Housing Age Profile
Some cities skew heavily toward one construction era; Delta Junction does not. The median build year of 1983 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 Delta Junction were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Delta Junction: 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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 48% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Delta Junction.
