The Food, Land & Water Project consists of four Workgroups to cover four distinct topics: polluted surface water, groundwater quality, groundwater quantity, and the future of Wisconsin working lands. The Groundwater Quantity Workgroup is considering competing uses of shared aquifers and the potential to reduce conflicts within communities. This Workgroup will focus on the water quantity issues in the “Central Sands” region and other areas in Wisconsin experiencing groundwater use conflicts. Four Workgroup meetings were held with the ideas, goals, and recommendations presented at the Food, Land & Water Conference on October 16 and 17, 2017. Below are some documents related to this ongoing progress:
- Groundwater Quantity Workgroup Charter
- Workgroup Meeting #1 (August 2016) Agenda and Minutes
- Workgroup Meeting #2 (November 2016) Agenda, Presentations (Central Sands Water Use Trends and Impacts Part 1 and Part 2, and WI Groundwater Law and Regulatory Program), and Minutes
- Groundwater Quantity Workgroup Interim Report to the Steering Committee (January 10, 2017) and Steering Committee Feedback Memorandum (February 2, 2017)
