Edge-of-field monitoring

Edge-of-field monitoring focuses on identifying and reducing agricultural sources of excess nutrients which can threaten the health of streams, rivers, and lakes. Edge-of-field monitoring assesses the quantity and quality of agricultural runoff and evaluates the effectiveness of conservation practices that aim to reduce nutrient loss.

Enhance Great Lakes Beach Recreational Water Quality Decision Making

Important questions about beach closures and management remain unanswered in the Great Lakes where over 500 beaches are routinely used along the nearly 11,000 miles of coastline. The economies of coastal areas are dependent on public confidence in the quality of water at the shoreline, and beach managers need reliable science-based information to make beach closure and beach management...

In the Great Lakes, large volumes of sewage never make it to wastewater treatment plants due to illicit discharges and leaking sewer infrastructure, but contamination can be difficult to detect. This study will define the utility and practicality of using optical sensors to identify the sources and timing of sewage contamination in surface water and storm sewers in real-time field settings....

The Great Lakes are an important freshwater source of drinking water, fisheries, and habitat. Chemicals of concern are introduced to the environment by human activities, but resulting ecological consequences are little understood. With federal and University partners, we are characterizing the presence of contaminants and potential effects to fish in Great Lakes tributaries.
