On Friday, a green-ish scum began forming in places along the banks of the Ohio River. At the time, the executive director of the Ohio River Valley Sanitation Commission (ORSANCO) wasn't concerned, but that changed this weekend. 

States in the Ohio River basin will be able to choose whether or not to follow pollution control standards set by the Ohio River Water Sanitation Commission. ORSANCO's board of directors approved the change at a meeting in Covington Thursday morning.
