Nutrient pollution is one of the most widespread, costly and challenging problems in the U.S., reflecting a close and complex interaction of nutrient concentrations with human cultural and economic activities and their associated land use. Lakes and coastal zones, often the receiving waters for high nutrient loads, can experience algal blooms, hypoxia and degraded habitats.
Over several decades, fundamental questions about the underlying mechanisms of adverse effects from nutrient pollution have been answered. Additionally, examples of successful remediation and restoration are emerging with greater frequency. With continued progress, these advances have raised the potential for establishing water quality and ecological goals and developing measurements and indicators to evaluate progress toward meeting those goals.
This webinar will examine these changing realities in nutrient management and will provide an overview of new research from EPA that develops and describes methods to quantify water quality and habitat status and trends in coastal waters for the purpose of nutrient management. Jim Hagy from EPA’s Office of Research and Development will present this webinar.
