Test your water knowledge

If you are reading this blog, the chances are you know a little something about water.

Here’s your chance to see how much.

Freshwater has a new quiz – about water, water use and water pollution – on our web site.

It will test your knowledge about how much mercury falls on Minnesota every year, why you really need to worry about silver carp and the contaminants that sometimes afflict private wells.

And, lest you think there is not much fun in a quiz like that, there also is a question about an old Hamm’s beer jingle. And there’s an essay question that involves food coloring and water conservation.

The quiz owes a lot to the U.S. Geological Survey’s Water Science School, which we also borrow heavily from in our web site’s updated Kids’ Page.

Take the quiz, see how you do. Then if you are moved to suggest a question for the quiz, go to our Facebook page and post it. We will send a 2014 Minnesota Weatherguide Environment Calendar to whoever suggests the best new question by the end of May.
