Nutrients are the biggest threat to local waterbodies, primarily because it is so common and widespread that people think of it as harmless. Too much fertilizer, grass clippings, and leaves in the water can lead to increased algae growth which is difficult to remedy, but it's easy to prevent. Residents can reduce runoff by installing rain gardens, using Florida Friendly Landscaping practices, using permeable pavement, maintaining proper drainage, and minimizing the use of fertilizers and pesticides.
