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

mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

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.

Pre-1986 construction accounts for about 25% of Middleton homes; older plumbing in any of them can still add lead at the tap.
