The goal of the project is the development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
This project will quantify and qualify the effectiveness of herbicide treatments and native plant re-establishment at Duck Lake through systematic vegetative surveys pre and post herbicide application and following mid-summer die-off of curly-leaf pondweed. The data and analysis will ultimately be used in the development of TMDLs, implementation and protection strategies for other lakes in the Middle Minnesota Major Watershed.

The objectives of this study were to examine ditch sediment and water samples for the presence and numbers of E.coli and to determine what proportion of the E.coli were stable member of the microbial community (i.e. indigenous to the sites) and what proportion were likely transient or only present because of run-off. Researchers used sophisticated DNA technology to determine the potential sources of E.coli present in the ditch sediment and water samples.
