Continued Statewide Endocrine Disrupting Chemical Study

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. Collection of field parameters (temperature, pH, dissolved oxygen, specific conductance), nutrients (chemetrics), and organic matter (fluorescence); Identify set of suitable monitoring wells or supply wells within 1 km of the lake shore. Collect water-level data and develop potentiometric map; Synthesize geospatial, physical and chemical characterization, and hydrological data into a map of the 4 major microhabitats (with detailed subclassifications). MPCA EAO staff will provide technical assistance and oversight of the project.
