The County Well Index (CWI) contains well and boring records wells within Minnesota; over 400,000 records. It is the principal source of well construction information and geologic interpretations of well records and also contains soil boring records, mineral exploration test hole records, and scientific/research test hole records.
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 determine the magnitude and frequency of contamination from endocrine active compounds (EAC's) and other contaminants of emerging concern in shallow groundwater in non-agricultural areas of Minnesota. EACs and other contaminants of emerging concern in this study include compounds typically found in waste water, including, pharmaceutical compounds, antibiotics, and hormones. This project supports the third phase, including laboratory analysis of samples for an additional 80 wells to be sampled by MPCA staff.
BWSR will administer funding to eligible County projects that provide funds and other assistance to low income property owners to upgrade or replace Noncompliant Septic Systems. BWSR will also manage annual reporting completed by each County.
The Minimal Impact Design Standards (MIDS) project represents the next generation of stormwater management in Minnesota. MIDS offers guidelines, recommendations and tools that help low impact development practices be implemented more uniformly across Minnesota's landscape and provides guidance to effectively implement the concepts and practices of low impact development. Products include performance goals for new development, redevelopment and linear projects, a graphic user interface calculator and flexible treatment options for sites design.
The Minimal Impact Design Standards (MIDS) project represents the next generation of stormwater management in Minnesota. The consultant was hired to conduct research and design specifications for permeable pavement and turf.
This project will develop a reasonable statewide estimate of recharge using the Soil-Water-Balance (SWB) Code (Westenbroek and others, 2010), validate the simulation results, and conduct a parameter sensitivity analysis to identify the most sensitive model parameters. For the purposes of this application of the SWB application, comparing the simulation results will be conducted on selected watershed basins in the state against previously established recharge estimates.
This project will provide an interpretive assessment of nitrogen concentrations in Minnesota rivers and streams, including spatial and temporal trends based on historical data sets. The trends analyses will provide information useful for evaluating nitrogen reduction efforts in the past couple of decades.
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.
This project will improve water management in the State of Minnesota. The result will be a water management tool that can be used by the Minnesota Pollution Control Agency (MPCA) to determine low flow statistics when establishing permit discharge limits and by the Minnesota Department of Natural Resources (MDNR) to help in water appropriations and permitting. This tool will also be used by watershed districts in understanding and quantifying the State's water budget, the Nature Conservancy in its Ecological Limits of Hydrologic Alteration (ELOHA) process, and the U.S.
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.
