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 project goal is to conduct water chemistry monitoring at four subwatershed sites and one basin site in 2016, 2017, 2018 and 2019. Water chemistry monitoring will be conducted at a wide range of flow conditions with emphasis of collecting samples during periods of moderate and high flows after runoff events, as defined in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance. The data collected will be submitted to the Minnesota Pollution Control Agency (MPCA) and used in the FLUX32 model for calculating pollutant loads.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
The goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
This project will provide the monitoring of reaches where there are data gaps, incorporate new data and analyze relevant data, identify pollutant sources, hold a stakeholder meeting, and gather information towards the future development of a Draft Restoration (TMDL) and Protection Plan.
The primary goal of this project is to examine the calibration and validation of recently extended Hydrological Simulation Program – FORTRAN (HSPF) watershed models for the Mississippi River-Headwaters, Mississippi River-Grand Rapids, Mississippi River-Brainerd, Mississippi River-Sartell, Mississippi River-St. Cloud, Leech Lake, Pine River, Crow Wing River, Long Prairie River, and Redeye River watersheds and revise the calibration.
