Stream Water Quality
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.
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 GLRI Urban Stormwater Monitoring effort brings together the expertise of the USGS with local and national partners to assess the ability of green infrastructure to reduce stormwater runoff in Great Lakes urban areas.
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.
The USGS Mercury Research Lab is a national leader in advancing mercury research and science, specializing in low-level mercury speciation and isotope analysis and mercury-source fingerprinting. The MRL leads national cutting-edge collaborative studies, including state-of-the-art sample analysis, methods development for field and lab procedures, and data interpretation and dissemination.
Fluvial geomorphology studies provide an understanding of the physical processes responsible for shaping the character of streams and their riparian zones across both glaciatied and unglaciated regions of Wisconsin and the midwestern U.S.
The TC Chamberlin Modeling Center provides one-stop access to advanced computing so no project is limited by a lack of computer power. The Center can provide hardware access, assistance with migration and implementation, and training. We also develop, test, and disseminate state-of-the-art computational and analytical techniques and tools so models can be more effectively used in decision-...
The effectiveness of green infrastructure (rain gardens and decreased impervious surfaces) at reducing stormwater runoff is being assessed at a redevelopment project at Gary City Hall (Gary, Indiana). This study will evaluate pre- and post-construction hydrologic conditions using data collected by monitoring storm-sewer flow, groundwater levels, soil moisture, and meteorological conditions....
Assessing stormwater reduction using green infrastructure: Niagara River Greenway Project (Buffalo, NY)
The effectiveness of green infrastructure (porous asphalt, planter boxes, rain gardens, and the removal of impervious pavements) at reducing stormwater runoff is being assessed at the Niagara Street redevelopment project in Buffalo, New York. This study will monitor pre- and post-construction storm-sewer flow, groundwater levels, evapotranspiration, precipitation, and soil moisture.
The effectiveness of green infrastructure (including urban land conversion and bioswales) at reducing stormwater runoff is being assessed at RecoveryPark, a redeveloped urban farm in Detroit, Michigan. This study will monitor pre- and post-construction storm-sewer flow, groundwater levels, precipitation, and potential evapotranspiration.
Great Lakes Restoration Initiative edge-of-field monitoring focuses on identifying and reducing agricultural sources of excess nutrients which threaten the health of the Great Lakes. The USGS supports these efforts by utilizing edge-of-field monitoring to assess the quantity and quality of agricultural runoff and evaluate conservation practices that aim to reduce sediment and nutrient loss....
Evaluating chloride trends due to road-salt use and its impacts on water quality and aquatic organisms
Chloride, a key component of road salt, is soluble, highly mobile in water, and, at high concentrations, can be toxic to aquatic vegetation and wildlife. USGS scientists have been analyzing temporal, seasonal, and environmental trends in chloride concentrations across the U.S. to determine the effects that road salt may be having on water quality and aquatic organisms.
