The DNR works with the Minnesota Geological Survey (MGS) to convey valuable geologic and groundwater information and interpretations to government units at all levels, but particularly to local governments, private organizations and citizens.
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 DNR works with the Minnesota Pollution Control Agency and the Minnesota Department of Health to determine the level of contamination from mercury and other harmful chemicals in fish from Minnesota's lakes and rivers and to track the success of efforts to reduce mercury pollution. Clean Water Legacy funding is being used to significantly increase (more than double) the number of lakes and rivers that are assessed for mercury contamination on an annual basis. Fish are collected during DNR fishery surveys, processed for laboratory testing, and analyzed for contaminants.
The Index of Biological Integrity (IBI) is a tool that can identify water pollution problems based on the type and abundance of selected plants or animals. The Minnesota Pollution Control Agency (MPCA) uses IBIs for fish and macroinvertebrates (stream-dwelling insects and other critters) in streams to help determine whether these waterways are impacted by water pollution. The DNR has developed a similar tool for fish in lakes and is developing a tool for aquatic plants. Both are used to help the MPCA identify lakes that may be impacted by water pollution.
This project will complete a Acetochlor Impairment Response Report. This report will combine and coordinate information relating to actions being done in direct response to the acetochlor water quality impairments with those being done and support MDA’s on-going responsibility to assure pesticides are used in a manner that does not cause unreasonable adverse effects on the environment.
This project will establish a groundwater monitoring network in the 11 county metropolitan area. The network will provide information about aquifer characteristics and natural water trends by monitoring healthy aquifers (non-stressed systems). The project will also develop an automated system that captures groundwater level and water use data. This system will enhance evaluation of changes in aquifers that are stressed by pumping from existing wells.
This project will create a high accuracy elevation dataset - critical for effectively planning and implementing water quality projects - for the state of Minnesota using LiDAR (Light Detection and Ranging) and geospatial mapping technologies. Although some areas of the state have been mapped previously, many counties remain unmapped or have insufficient or inadequate data. This multi-year project, to be completed in 2012, is a collaborative effort of Minnesota's Digital Elevation Committee and partners with county surveyors to ensure accuracy with ground-truthing.
The Arts Education in Minnesota Schools Research Project is surveying all public and private schools to collect baseline data on the status of arts education statewide to serve as a resource for making data-driven decisions. A national research and evaluation company, Quadrant Arts Education Research, is conducting the study, comprised of three elements.
Successful long-term treatment of sewage depends on a system capable of providing adequate treatment and effective on-going operation and maintenance. Clean Water Fund Subsurface Sewage Treatment System (SSTS) Program Enhancement and Inventory funds are used by counties to strengthen programs dedicated to SSTS ordinance management and enforcement. These funds are used for a variety of tasks required to successfully implement a local SSTS program including inventories, enforcement, and databases to insure SSTS maintenance reporting programs.
This project will apply the Sunrise River watershed computer model generated under previous projects to selected scenarios of land-cover and land-management changes. The watershed model calibrated to conditions in the late 1990s will form the initial baseline against which all other model runs will be contrasted. Scenarios to be run will include changes in future land cover, agricultural practices, urban practices, and natural resource management.
This project will complete a chloride management plan which will lay out a strategy for addressing chloride impacts to our surface waters for the 7-county metropolitan area. This chloride management plan will satisfy EPA requirements for impaired waters, address waters not yet listed, and develop a strategy to protect waters that are currently meeting the water quality standards.
This project will provide the MPCA and all local partners in the Twin Cities Metropolitan Area (TCMA) the information and tools necessary to improve and/or maintain water quality with respect to chloride for the 7-county metropolitan area during the winter maintenace period.
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.
The DNR's Regional Clean Water Specialists and Area Hydrologists work with other state agencies and local partners to help identify the causes of pollution problems and determine the best strategies for fixing them. A statewide coordinator works with the DNR and external partners to ensure funds are spent in the most effective and efficient manner to meet the State's clean water goals.
The DNR provides technical support regarding the causes of and solutions to drainage impacts, actively engaging with other Minnesota modelers and scientists working on issues related to altered hydrology. We use state-of-the-art models to look at cumulative impacts of drainage and land-use practices and determine the benefits of site-specific best management practices. This involves collaboration with multiple partners and at multiple scales.
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.
