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.
PROJECT GOAL: Improve agricultural production and reduce flooding losses while minimizing the unwanted environmental impacts of subsurface drainage.
PROJECT OBJECTIVE: Demonstrate controlled tile drainage as a flood mitigation practice as well as the water quality and quantity benefits. The project is intended to set an example to increase the adoption of drainage water management practices in the Red River Valley.
Controlled drainage and a saturated buffer are both being evaluated as part of this project.
This is a joint project between the United States Geological Survey (USGS), Minnesota Pollution Control Agency (MPCA), North Dakota, and Manitoba. The project is a basin-wide, up-to-date water quality trend analysis using the "QWTrend" program for approximately 40 bi-national river sites to review nutrients, total suspended solids, total dissolved solids, sulfate and chloride from 1980 - 2015.
