The web site for the Florida chapter of the Sierra Club contains updates and press releases for a number of environmental issues. Information about clean water in Florida can be found at florida.sierraclub.org/water_quality.asp.
A recent update contains the Florida Slime Tracker Map. This is a Google map with markings for rivers, lakes, and wetlands in Florida. Zoom in on your favorite wet spot, click on the blue circle and you’ll see the state of slime for that location.
