Nutrient Management: Regulatory Approaches to Protect Water Quality Volume 1 -Review of Existing Practices iiiThe project team would like to acknowledge and thank the wastewater utilities involved in nutrient total maximum daily loads and NPDES permitting whose experiences were used as references in preparation of this report, including the Alexandria Sanitation Authority,
Abstract:Utilities work with regulators to treat wastewater to levels that protect human health and ecosystems. Water quality criteria and permits are based on scientifically defensible and shared understanding of sources of pollutants in a watershed, as well as treatment capabilities and costs to control these in the aquatic environment. The national discussion of nutrient impacts on water quality continues to evolve -issues in high...
