Researchers at Duke University have found elevated levels of lead contamination, as well as a number of other toxic contaminants, in the soil in Durham. Using tests they developed, they analyzed 99 soil samples from major streets, city parks, and the yards and foundations of old houses. In a study published in October, they provided a comprehensive assessment of lead introduced into the city by human activity.

The lead author of the study, Zhen Wang, joined Carolina Connection’s Sophia Ramirez to discuss their findings.
