STUART, FL - JULY 11: Dennis McGuire, who works for Ecosphere technologies, looks on as the companies Ozonix EF80 machine is used in an attempt to kill the awful smelling algae at the Outboards Only marina along the St. Lucie River on July 11, 2016 in Jensen Beach, Florida. The algae which is thought to be coming from from Lake Okeechobee as water is released has fouled coastal waterways, created angry communities, closed beaches and has had an economic impact as tourists and others are driven away by the smell and inability to enjoy some of the waterways.
