Groundwater sample collection and analysis will be conducted for contaminants of emerging concern (CEC) at large subsurface treatment systems (LSTS) and rapid infiltration basins (RIB), using an enzyme linked immunosorbent assay (ELISA) methodology. Results from the ELISA analysis will be reported to the MPCA and used to conduct follow-up investigations at a select number of these sites.
The Minnesota Pollution Control Agency (MPCA) has identified streamflow alteration as a key stressor on aquatic life, but the characteristics of streamflow alteration acting as a stressor has not been identified in the MPCA Watershed Restoration and Protection Strategy (WRAPS) process. Without indices that characterize streamflow alteration, the MPCA cannot quantitatively associate metrics of aquatic life condition to streamflow alteration. The lack of quantifiable indices limits the ability of the MPCA to assess environmental streamflow needs for streams and rivers throughout Minnesota.
The study will assess existing phosphorus data records and create a model to explain phosphorus loading into the Red River of the North. Studies have found that the majority of nutrient loading in the stream located in agricultural areas occurs with sediment loading since nutrients are typically bound to sediment particles.
The Minnesota Department of Agriculture has partnered with the USDA National Agricultural Statistic Service (NASS) and University of Minnesota researchers to collect information about fertilizer use and farm management. Partners have pioneered a survey tool for characterizing fertilizer use and farm management on a regional and statewide scale. Surveys are conducted over the phone. NASS staff are highly skilled at obtaining critical information over the phone with minimal time and burden on the producer.
The 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 permitting.
