The Lynchburg Fire Department said in a Facebook post that crews responded to a 911 call about a creek near Hendricks Street that had turned "almost completely white in color." Advertisement Investigators soon determined the white color was due to waste milk from the Westover Dairy plant. The department said a clogged drain line at the plant led to the milk overflowing into a storm sewer and making its way into the creek. The clog was cleared and the overflow stopped, firefighters wrote. The post said local and state water resources officials were informed of the incident. The department said "there is no public health threat" from the waste milk.
