Chemical contamination has left over 100,000 Alabamans without drinkable tap water, possibly until the fall, according to a warning issued by officials on Thursday. The West Morgan-East Lawrence Water Authority (WMEL) advised roughly 100,000 Alabama residents not to use their tap water for drinking or cooking, as it has been contaminated with potentially hazardous chemicals that can cause cancer, birth defects, and developmental problems in children.

The warning comes on the heels of a US Environmental Protection Agency (EPA) advisory that revealed higher than previously thought levels of synthetic chemicals known as PFOS (Perfluorooctane sulfonate) and PFOA (perfluorooctanoic acid) in Alabama waters. Scientists found PFOS and PFOA in the blood of “nearly all the people they tested,” but in low concentrations, the EPA said in its May 19 warning. FULL REPORT
