The goal of this project is to collect and analyze samples from lake, stream, wild rice paddy, and experimental field sites across a spectrum of sulfate concentrations and wild rice plant abundance. The scientific information developed will be part of the evidence used by the MPCA in its decision as to whether or not a change to the existing sulfate standard is necessary, and if so, what the revised standard should be.
The MPCA is undertaking a study to investigate the potential effects of elevated sulfate on the growth of wild rice. One high-priority hypothesis is that the conversion of sulfate to sulfide in anoxic subsurface sediment may harm the roots of wild rice, either directly, or indirectly. The goal of this project is To observe and develop an understanding of exposure of wild rice roots to changes in concentration of sulfide and related chemicals over time and space (depth of sediment and distance from roots).
This project will provide lab analyses and interpretation required for 2012 wild rice field survey. The 2012 lab analyses will be merged with the 2011 field survey data and determine what additional work, if any, is needed during the 2013 field season.
The MDH Environmental Laboratory provides essential analyses of water for the MPCA Wild Rice Standards Study, which is gathering information about the effects of sulfate on the growth of wild rice. For this study, the lab developed a ultra-sensitive test for hydrogen sulfide, which greatly facilitated the research. For this large study, the lab staff analyzed several thousand water and sediment samples from lakes, wetlands, rivers, rice paddies, experimental mesocosms, and hydroponic experiments.
This project will produce a Winter Maintenance Assessment tool prototype that allows users to create a customized approach to modify their existing winter maintenance program that will reduce their road salt use. The tool will allow users to take inventory of their current practices and evaluate how they are doing today and where they have the most potential to reduce salt usage.
The goal of this project is to maintain and make enhancements to the Winter Maintenance Assessment tool (WMAt), which is a necessary technical resource and planning tool for stakeholders and permittees to implement the chloride reduction strategies described in the Chloride Management Plan. The WMAt is critical for assisting stakeholders in meeting the water quality goals of the Chloride Management Plan without compromising public safety, and allowing for consideration of the varying resources and conditions for each individual winter maintenance program.
The goal of this project is the development of an automated planning tool to complete the Twin Cities Metropolitan Area Chloride Watershed Watershed Restoration and Protection Strategy (WRAPS).
Wolverton Creek is a 25 mile long tributary to the Red River of the North. Its watershed drains approximately 105 square miles located in Wilkin and western Clay Counties. Wolverton Creek is the outlet for numerous ditch systems and natural drainage in the area and is a significant contributor of sediment to the Red River. The City of Moorhead and other downstream communities obtain drinking water from the Red River. Since 85% of Moorhead's drinking water comes from the Red River, high turbidity results in
higher treatment costs for their drinking water system.
The United States Environmental Protection Agency (USEPA) requires the Minnesota Pollution Control Agency (MPCA) to carry out the Total Maximum Daily Load Program (TMDL) in the state of Minnesota. Minnesota has an abundance of lakes and river reaches, many of which will require a TMDL study. In an effort to expedite the completion of TMDL projects, the MPCA has decided to construct watershed models. These models have the potential to support the simultaneous development of TMDL studies for multiple listings within a cataloging unit or 8-digit Hydrologic Unit Code watershed.
This project will train MPCA field staff in the proper calibration, deployment, maintenance and storage of water quality collection Sondes. Training event will cover general sonde overview, sonde maintenance, calibration procedure, short-term storage, long-term storage and 650MDS overview.
