The Florida Department of Environmental Protection says varying levels of cyanotoxins have been identified, increasing chances that the discharge at Piney Point will trigger a blue-green algae bloom. Researchers monitoring water quality near the former Piney Point phosphate plant have identified increased levels of blue-green algae in the area where more than 200 million gallons of polluted water was discharged recently.
