Fresh off a significant court victory in its battle to preserve Florida's freshwater springs, leaders of the Florida Springs Council appeared on WMNF WaveMakers to discuss how the public can get involved.Florida has the highest concentration of freshwater springs in the world but they are under stress from pollution, over-pumping and neglect, said Ryan Smart, executive director of the nonprofit Florida Springs Council. One of the greatest sources of pollution is nitrogen and phosphorus caused by fertilizer runoff from urban lawns, said Michael McGrath, works for the Florida Sierra Club and is a board member for the Springs Council.
