Housing & Infrastructure in Callaway
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
Check your utility's service line inventory as well as your home's build year; in Callaway, where the median build year is 1997, both pieces help.
Most homes in Callaway were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Callaway
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.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
