The phosphorus cascade: Navigating from sources to solutions

This presentation will review the latest research on inputs, budgets, effects, legacies and management related to non-point source nutrient pollution.  Using examples of phosphorus budgets at the national, regional and local scales, Jana Compton from EPA’s Pacific Ecological Systems Division in Corvallis will walk through examples about nutrient impacts, and lessons learned from managing nitrogen.  Her work focuses on analyzing data from EPA’s National Aquatic Resources Survey and National Nutrient Inventory to understand the impacts of land use and watershed processes on stream and lake nutrients across the US.  

Impact/Purpose

The NSF-funded Sustainable Phosphorus Alliance hosts an annual Phosphorus Forum in which knowledge leaders interact around topics related to phosphorus sustainability.  PESD’s Jana Compton will present the keynote talk titled “The phosphorus cascade:  Navigating from sources to solutions.”  She will review the latest research on phosphorus inputs, budgets, water quality condition, legacies and management using examples of phosphorus budgets at the national, regional and local scales.  This work focuses on analyzing data from EPA’s National Aquatic Resources Survey and National Nutrient Inventory to understand the impacts of land use and watershed processes on stream and lake nutrients across the US.
