One of the hottest and driest months of May on record may have contributed to the growth and spread of the toxic algae bloom wreaking havoc in the drinking water in the Salem, Ore., area. The algae bloom was originally spotted in Detroit Lake on May 8, 2018, and reached highly toxic levels around May 21, according to officials.
