What is polluting Biscayne National Park?

parts/content-body.any.php

Just south of Miami, Biscayne is the largest marine park in the National Park System. For years Florida Power and Light (FPL) has known that their cooling canal system used at their Turkey Point power plant, is polluting and adding salt to the Biscayne Aquifer and Biscayne National Park. Sign the petition demanding that FPL stop the leaks, clean up Turkey Point and save Biscayne Bay: http://bit.ly/SaveBiscayneBay
