A Watershed Approach to Water Quality Criteriaby Scott J. Kenner, Univ of Florida, Gainesville, United States,
Abstract: Water quality has been managed historically using water quality criteria implemented through the NPDES permitting process. Many water bodies have water quality better than that defined by beneficial use criteria while at the same time some parameters naturally exceed defined criteria. Antidegradation policy provides a tool for establishing criteria that reflect ambient conditions in the watershed. An approach to development of water quality criteria that reflect the ambient watershed conditions has been applied to the Suwannee River basin. The criteria developed reflect both time and spatial variability within the basin.
