Housing Age Profile

Housing age is a rough starting point, not an answer. Union Star has a median build year of 2004, but any single home may be older or newer than that figure, may have had plumbing replaced, or may still have original fixtures. Lead can also come from a service line or older brass fittings, so a water test or a check of the utility's service line inventory says more about one address than the citywide build year does.

2004
Median Year Built
29%
Pre-1986 (lead solder era; lead paint banned 1978)
17%
Pre-1970 (Lead Pipes Risk)
Pre-1970 (17%) 1970–1986 (12%) Post-1986 (71%)

Most homes in Union Star were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Protecting Children from Lead in Union Star

29%
Homes Built Before 1986

Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

Several limits apply to the lead numbers for Union Star. The figure shown is an average of 90th-percentile results from ZIP codes in the city, and it is below 0.010 mg/L; the federal action level of 0.015 mg/L applies to each water system's own 90th percentile, not to an average like this one, and being below it does not make water free of lead. About 29% of local homes were built before 1986. A test at the home's own tap shows its level, and a filter certified to NSF/ANSI 53 for lead reduction is an option if a test finds lead.
