When it comes to lead contamination, it's not just water you should be worried about. The Doctors share how a study from Tulane University found a link between the lead in soil and the lead in children’s blood.

"Lead is one of the most significant environmental hazards we face," she says, explaining lead usually concentrates in the top two to three inches of soil.

She notes children under 5 are particularly vulnerable to lead poisoning and it can affect their brain development and may cause lower IQs and behavioral issues. She advises that parents with children under 5, speak to their doctor about lead testing, as the symptoms of lead poisoning are not always obvious.
