A multi-partner effort has begun to study the amount of nitrate-nitrogen (nitrate) leaching loss that occurs below an agricultural field recently converted from timber land to irrigated row crop production. The landowner has made the property and their staff available to better understand the deep drainage and nitrate leaching dynamics following this type of land use change. This study is unique.
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 Lake Superior Beach Monitoring and Notification Program exists to test recreational beach water and notify the public if bacteria levels become unsafe. This project will expand the Beach Program to include additional outreach efforts, sanitary surveys and testing of new technologies to improve the Beach Program. Monitoring results will be used to inform the public, find the sources of bacterial contamination and address polluted runoff from improper waste disposal.
The objective of this project is to build on previous efforts aimed at determining the public health risk due to virus contamination in Minnesota groundwater. The Minnesota Department of Health will examine the occurrence of viruses in non-disinfecting groundwater sources in Minnesota as well as evaluate the association between source water virus occurrence and community acute gastrointestinal illness.
This project was part of a three-state partnership to test, demonstrate and promote a simple, inexpensive and reliable new system for edge-of-field water monitoring. The University of Wisconsin-Platteville Pioneer Farm, in collaboration with UW-Platteville Engineering, has developed a low cost monitoring system that can obtain good quality, edge-of-field monitoring data in agricultural settings. By eliminating unnecessary features and assembling components in-house, the prototype monitoring system derives the majority of cost savings with minimal sacrifice in accuracy.
Staffing support to evaluate the performance of existing stormwater infiltration sites, as identified in the Minimal Impact Design Standards (MIDS) project. Monitor the range of existing infiltration devices in Minnesota and compare to design criteria, maintenance records, and quantify year-round infiltration rates. Develop and refine pretreatment options and standards for municipal stormwater treatment.
This project supports activities by Minnesota Pollution Control (MPCA) Watershed Division staff that provide technical assistance, project oversight, coordination, outreach and other agency activities associated with assessing, listing and conducting Total Maximum Daily Load (TMDL) studies throughout the State of Minnesota. Project also includes lab analysis, equipment, and fieldwork expenses associated with TMDL work at the MPCA.
This project supports monitoring and assessment activities by MPCA EAO staff and includes lab analysis, equipment, and fieldwork expenses associated with monitoring and assessment activities within the described priority watersheds. Lake Monitoring: Lakes are monitored for nutrients, clarity and other information to provide the data needed to assess the aquatic recreation use support. Biological and Water Chemistry Stream Monitoring: Monitoring to assess the conditions of streams in each watershed.
The Minnesota Pollution Control Agency (MPCA) uses a watershed-oriented approach to assess surface water quality and define restoration and protection measures. Each of Minnesota's 81 major watersheds is assessed intensively every 10 years, based on a staggered schedule that addresses, on average, eight watersheds per year. To increase the amount of data directly available to the public online, and to make internal operations more efficient, the MPCA started a multi-year Watershed Data Integration Project (WDIP).
Arsenic occurs naturally in soil and minerals and is commonly found in groundwater throughout much of Minnesota. The occurrence and distribution of arsenic in groundwater is difficult to predict. Research is steadily increasing our understanding of the mechanisms and geologic conditions that determine arsenic occurrence in groundwater. The arsenic concentration in a new well, measured at the time of construction, is sometimes higher or lower, compared to subsequent sampling results.
MPCA will administer funding to eligible Local Governmental Units to use MPCA-approved Advanced Inspectors to conduct work in accordance with Minn. Rules 7080, 7081, and 7083, which requires proper location, design, installation, use and maintenance of an individual subsurface sewage treatment system (SSTS) with a design flow of 2,500 gallons per day or more that protects the public health, safety, general welfare, and the environment by the discharge of adequately treated sewage to the groundwater. Multiple contracts will be awarded.
