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.
The project will involve monitoring twelve stream sites and one lake in Jackson County. The stream sites are known to be impaired. The purpose of monitoring in multiple locations is to determine the source of the impairments.
A Level III Feedlot Inventory in the West Fork Des Moines River Watershed identified the need for a new manure storage basin. The Heron Lake Watershed District will be partnering with Murray County, Murray Soil and Water Conservation District, and Southwest Prairie Technical Service Area to construct the basin to ensure that manure and milk house wastewater will be properly stored. In addition, the project will decrease the size and usage of open lots using buffer strip and pasture to significantly reduce nutrient loading.
The West Fork Des Moines Headwaters Water Sampling Project consists of collecting water samples and along with field data from three sampling sites within the West Fork Des Moines River Headwaters located in Murray County, MN. The sampling will take place from May 2014 through September 2014, and then again from June 2015 through August 2015. During this sampling regime, the three stream sites will be sampled sixteen times. Field replicates as well as blanks will be collected also. The three sites identified for sampling are the West Fork Des Moines RIver, Beaver Creek, and Lime Creek.
The Statewide Sediment Network was established to measure the levels of suspended sediment concentrations and particle size distributions at eight sites across Minnesota to evaluate the amount of sediment carried by rivers. USGS sample collection and laboratory analysis techniques provide a more rigorous, robust, and technically accurate measure of sediment in water than the current use of total suspended solids as the measure of sediment in water.
The Southwest Prairie Technical Service Area 5 (SWPTSA), located in the southwest corner of Minnesota, encompasses 11 Soil and Water Conservation Districts (SWCDs): Cottonwood, Jackson, Lac Qui Parle, Lincoln, Lyon, Murray, Nobles, Pipestone, Redwood, Rock, and Yellow Medicine. This project will protect natural resources within the three major river basins of Minnesota, Missouri and Des Moines Rivers. The SWPTSA will assist member SWCDs in locating and identifying priority subwatersheds that have soil erosion and water quality issues using terrain analysis.
The goal of this project is to establish a framework that the local government can use to guide their involvement as the WFDMR Watershed Project progresses over the next four years. This will enhance the success of the overarching goal of providing a framework for which the local government and watershed organizations can engage the public in a manner that will lead to water quality improvement. This will result in strategies to protect or restore the waters in this watershed.
