With limited funds and limited staff time available for targeting critical service areas and implementing Best Management Practices (BMPs), Geographic Information System (GIS)-based tools that pinpoint locations where BMPs will have the highest effectiveness are increasingly important. The Blue Earth County/SWCD Watershed Implementation Targeting project will utilize LiDAR topographic data to determine areas of high importance for BMP implementation. The county is located in the Blue Earth, LeSueur, Watonwan and Middle Minnesota watersheds where there is a high density of impaired waters.
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 Faribault County Soil and Water Conservation District Drainage Engineer will inventory public drainage ditches to identify priority systems and areas where erosion, sediment, and nutrients contribute to water quality degradation. Sites identified for potential side inlet control, buffer strip need, or water storage will be prioritized for landowner contact and follow through by seeking external funding opportunities.
Working with a consultant, a current online database to manage public drainage systems will be enhanced and a corresponding mobile inspection app will be developed to facilitate drainage compliance and improve inspection planning. With these improvements, a long-term, comprehensive, GIS-compatible database will be in place to help plan, collect, document, summarize, and analyze system condition, repair needs, and violations with the overall goal of protecting and improving water quality.
