Data & Mapping
Use the interactive map to determine how many children are impacted by lead poisoning.
Childhood lead poisoning has decreased in recent years, but there are still many cases each year in Delaware County. In 2022, a total of 307 children had an elevated blood-lead level (EBLL) in Delaware County. An EBLL means one venous blood test result of 3.5 μg/dL or higher, or two capillary tests of 3.5 μg/dL or higher, within 12 weeks. Like in other areas in Pennsylvania, testing is limited, with an estimated fewer than 10% of children in Delaware County under age 15 having had their blood tested in 2022. This low testing rate means more children could have lead poisoning than we realize.
According to the CDC, those at increased risk of childhood lead poisoning include children from low-income households, children less than 6 years old, immigrant and refugee children, and children whose parents work in industries or have hobbies that expose them to lead.
