This project will provide notification of the potential for coal tar contamination, establish a storm water pond inventory schedule, and develop best management practices for treating and cleaning up contaminated sediments. The sampling design includes 15 stormwater ponds, 5 each from residential, commercial, and industrial land use areas. Municipalities in the metro area with MS4 permits of stormwater ponds will be contacted to nominate candidate sites for this study. GPS coordinates will be taken at all sampling sites.
USGS will complete the following activities in support of the SCSU project Assessing the Contribution of Microhabitat Differences on Biological Effects in Bluegill Sunfish in Sullivan Lake, MN-Continuation of MN Lakes Study 2010-2011. Geospatial analysis of maps, aerial photography, satellite imagery, GIS data, and field mapping (topography, bathymetry, vegetation, habitat); Bulk characterization of the physical and chemical features of the littoral zone, inflows, and outflows.
This project will create a high accuracy elevation dataset - critical for effectively planning and implementing water quality projects - for the state of Minnesota using LiDAR (Light Detection and Ranging) and geospatial mapping technologies. Although some areas of the state have been mapped previously, many counties remain unmapped or have insufficient or inadequate data. This multi-year project, to be completed in 2012, is a collaborative effort of Minnesota's Digital Elevation Committee and partners with county surveyors to ensure accuracy with ground-truthing.
This project will assess the exposure and effects of WWTP effluent on a model vertebrae organism, the fathead minnow. Through a series of controlled experiments, to be conducted on-site of the WWTP utilizing the Mobile Exposure Laboratory Trailer (MELT),SCSU will address (1) onset and timing of acute exposure effects, (2) downstream exposure effects, and (3) reproductive consequences of exposure for male and female fathead minnows. MPCA EAO staff will provide technical assistance and oversight of the project.
This project will develop databases to manage TMDL activities and track progress. It will also provide assistance to promulgate rulemaking. This project will also support agency operations to review civic engagement proposals from basin and sub basin organizations. Assistance provided to establish a coalition between organizations creating productive environments where citizens and stakeholders can come together to dialogue about issues of concern to them and create their own visions and strategies for TMDL-related change/issues in their communities.
