Pre-1970 (6%) 1970–1986 (21%) Post-1986 (73%)

Most homes in Hallie 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 Hallie

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.

27% of the Hallie housing stock dates from before 1986, the year Congress limited lead in pipes, solder and flux. Water systems report lead as the 90th percentile of their tap samples, and the average of those results across the city's ZIP codes is below 0.010 mg/L. Because lead in drinking water usually comes from corrosion of a building's own service line and plumbing, that average cannot stand in for a single address.
