Ask the editor: Minnesota's ground water problem
Not often. So that makes some people wonder how much it matters whether an irrigator gets one. I think one reason it's unusual is that typically a well owner has to ask for the permit after he’s made a significant investment in drilling the well. There’s a fairly new provision in state law that lets someone ask for a preliminary assessment before he invests. My understanding is that has led the DNR at least in a few cases to tell farmers they may have trouble getting a permit.
