MMSD Watercourse Corridor Study: Contaminants in Water and Sediment

There are many kinds of chemical, physical, and biological contaminants contained in water and sediment, and new or “emerging” contaminants are continually being discovered. USGS investigations of contaminants in the MMSD Watercourse Corridor Study include studies of PFAS, PAHs, microplastics, and wastewater contamination as well as modeling long-term trends in water quality.

Lake monitoring and research

Studying lakes provides an improved understanding of lake ecosystem dynamics and valuable information that helps lead to sound lake-management policies. The USGS collects hydrologic data in lake settings, studies water and nutrient budget development, conducts source-loading analysis, explores groundwater interactions, and performs lake water-quality modeling.

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 decisions...

Using optical sensors to detect sewage contamination in the Great Lakes

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.

Dane County water-quality monitoring program

Many Dane County, Wis., streams and lakes have been degraded due to excessive nutrients and sediment contributed primarily by agriculture and urbanization. The goal is to build a long-term base of streamflow, lake stage, and water-quality data essential for water-resource planning and assessment purposes for streams and lakes in Dane County, with a focus on the Yahara River Basin.
