Water Quality and Ecology of Gunston Cove

The video discusses the Gunston Cove, a freshwater embayment downstream from a major sewage treatment plant in Fairfax County. It highlights the importance of clean water, detailing the primary, secondary, and tertiary treatment systems that process 45 million gallons daily. The video emphasizes the significance of maintaining low nutrient and bacteria levels to support the ecosystem. A long-term study with George Mason University has shown improvements in water quality and underwater vegetation, which benefits fish habitats. The efforts have gained national and international recognition.
