Concerns raised about toxic exposure in the aftermath of Helene floodwaters

Local officials, academic researchers, and volunteer responders have raised concerns about chemical and biological contamination brought by the floodwaters of Hurricane Helene in the southeastern U.S. last week, which potentially threaten the safety not only of drinking water but also the quality of soil—leading experts to call for tighter regulations on stored pollutants.

Helene struck Florida as a Category 4 hurricane on September 26 and swept through a number of states in the days that followed.
