Chippewa County Study Links Sand Mining, Agriculture To Stream Declines

Multi-Year Project Uses Computer Modeling To Predict Groundwater Impacts From Soil Compaction, High-Capacity Wells

A multi-year study of groundwater use in Chippewa County shows that stream levels can be negatively impacted by frac sand mining and irrigated agriculture. Authors and stakeholders say the results can inform future regulations on high-capacity wells and industrial sand mining operations.

Researchers from the Wisconsin Geological and Natural History Survey and U.S. Geological Survey (USGS) partnered with Chippewa County, sand mining companies, farmers and other stakeholders to measure potential impacts to groundwater in the county. The study was based on data gathered between 2011 and 2014, as well as predictive computer modeling....


Ken Notes: 2011 and 2014 data, my guess is that it is worse today. New AG with mega farms and large surface mines are new and we need new laws to regulate them.
