Chemicals of Concern in the Great Lakes Basin

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.

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...

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....

MMSD Watercourse Corridor Study: Ecological Assessments and Trends

Changes in streams that result from urban development such as loss of stream habitat, inadequate or flashy streamflow, and degraded water quality can adversely affect communities of aquatic organisms. MMSD Watercourse Corridor Study ecological assessments evaluate water quality over time by pairing community assessments of aquatic organisms with chemical assessments using passive samplers.

Monitoring and predicting the impacts of trees on urban stormwater volume reduction

Much has been learned about how effectively individual green infrastructure practices can reduce stormwater volume, however, the role of urban trees in stormwater detention is poorly understood. This study will quantify the effect of tree removal on the urban hydrologic cycle and measure the impact that trees have on stormwater runoff volume.

Arsenic in Minnesota groundwater—Occurrence and relation to hydrogeologic and geochemical factors

Geologic-sourced arsenic is common in Minnesota groundwater. Drinking-water managers, well owners, and well contractors need to know where and why high arsenic in groundwater is likely to occur in wells in order to take measures to protect public health. The USGS is assessing the spatial distribution of high arsenic groundwater in Minnesota, and identifying factors affecting arsenic...

Using leaf collection and street cleaning to reduce nutrients in urban stormwater

Decaying organic materials, like leaf litter, can release excess nutrients into local streams and lakes, causing eutrophication and algal blooms. To determine if a municipal leaf collection and street cleaning program can reduce nutrients in stormwater runoff, the USGS measured phosphorus and nitrogen in stormwater from residential areas in Madison, Wis.

The cold-loving fungus (Pseudogymnoascus destructans, or Pd) that causes white-nose syndrome, a disease that has killed millions of North American bats during hibernation, could also spread in summer months. Bats and humans visiting contaminated caves and mines can inadvertently contribute to the spread of the fungus, according to a recently published study by the U.S. Geological Survey.
