Housing & Infrastructure in Oronogo
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Housing age is a rough starting point, not an answer. Oronogo has a median build year of 1992, 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.
Most homes in Oronogo were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.
Source: U.S. Census Bureau ACS B25034.
Lead Exposure Risk for Children in Oronogo
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.
A tap test is the direct way to learn the lead level in a given Oronogo home; 28% of local housing predates 1986.
