Once thought to have an essentially inexhaustible groundwater supply, Minnesotans are now realizing our rates of use are regionally unsustainable. Recent advanced modeling by the MN DNR and Metropolitan Council of aquifer supplies, in conjunction with predicted demand, indicate the major metropolitan area aquifers are currently subject to extraction rates that exceed recharge. Simply stated, we are mining our groundwater.
Ensuring natural resource practitioners are applying state-of-the-art approaches is the best way to achieve optimum Best Management Practice (BMP) selection, design, and placement in the landscape, thereby maximizing Clean Water Fund (CWF) benefits. To that end, it is critical to train new staff, create modeling protocols for new BMPs, refine and calibrate models, and test ever-advancing modeling applications.
