This provides a project manager to work with regulated parties to identify new or more efficient ways of meeting standards at wastewater treatment facilities (municipal and industrial).

The Watershed Health Assessment Framework (WHAF) is a web-based tool for resource managers and others interested in the ecological health of Minnesota's watersheds. The framework uses five ecological components to organize and deliver information about watershed health conditions in Minnesota. The five components are hydrology, connectivity, biology, geomorphology, and water quality. Statewide GIS data from DNR and partner agencies are used to calculate health scores that reveal similarities and differences between watersheds.

The DNR provides technical support related to the causes of altered hydrology and watershed management solutions. We use state-of-the-art models and statistical methods to look at cumulative impacts of drainage and land-use practices and determine the benefits of best management practices. This involves collaboration with multiple partners at multiple scales.

This project delineates and maps watersheds (drainage areas) of lakes, rivers, streams, and wetlands for the state of Minnesota and provides watershed maps in digital form for use in geographic information systems. These maps become the basis for clean water planning and implementation efforts.

DNR regional clean water specialists and area hydrologists work with regional staff from other state agencies and with local partners to help identify the causes of pollution problems and determine the best strategies for fixing them. We collect and analyze stream channel stability and streambank erosion data to help identify root causes of certain water quality impairments in streams.

This project will apply science to identify viable and priority wetland restorations and rehabilitations that will deliver sustainable water quality benefit, along with flood storage and habitat benefits. Decision tools will be developed to assist with selection of restoration projects.

The MPCA is currently collecting additional information needed to evaluate the 10 mg/liter wild-rice-based sulfate standard and has received funding through legislation passed during the 2011 Special Session to implement a wild rice research plan and contract with scientific experts to further understand the effects of sulfate on the growth of wild rice. The goal of this project is to determine responses of wild rice to sulfate and the products of geochemical transformations of sulfate.

This project makes an additional plant growth chamber available to increase efficiency for the MPCA Wild Rice Standards Study, which is gathering information about the effects of sulfate on the growth of wild rice.

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.

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).

Youth Energy Summit (YES!) expands its successful model to improve local waterways by mobilizing over 20 youth-led teams in Minnesota communities to complete water quality related projects, moni-toring and reporting.

There has been a sharp decline in participation in outdoor recreation and education amongst youth, particularly in urban areas. Some argue that youth who have meaningful outdoor education experiences are more likely to become engaged in environmental stewardship and invested in outdoor resources as adults.

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.

Zebra mussels are an aquatic species that are invasive in Minnesota and severely threaten native fish and other aquatic species by disrupting food webs and damaging spawning habitat. Their range continues to expand within Minnesota lakes and rivers, where they are spread through the transporting of water, vegetation, or equipment from an infested water body. Once established zebra mussels are very difficult to control and there is an immediate need for safe and effective control measures to reduce their impacts in the state.
