Water quality in the groundwater basin that contributes to springflow has declined in recent years. In particular, the increased concentration of nutrients, especially nitrates, and the decreased clarity of the water at the headsprings are trends that could eventually reduce the beauty of Silver Springs and the Silver River, and reduce the enjoyment of these resources by residents and visitors. There has also been a long-term reduction in the flow of the group of springs in the Silver Springs complex.
The increased nutrients create an overabundance of aquatic plants and algae. This is a threat to the remarkable clarity of water at Silver Springs, and disturbs the balance of the fisheries and aquatic ecosystems within the springs and the river. Community groups are currently contributing many hours of volunteer labor to rid the river of water lettuce in the Silver River and headsprings.
