There’s an old saying among veterans of water wars: “Whiskey’s for drinking, water’s for fighting over.”

Our pals over at Minnesota Public Radio will undoubtedly have a much more civilized – and sober – discussion of that state’s water quality battles today.

The chat, called "Farming and Pollution," will include a corn and soybean farmer from western Minnesota and the water quality director for the Minnesota Center for Environmental Advocacy.

The live conversation – viewable here – follows MPR’s “Cleaning Minnesota’s Water” series.
