Feb. 19, 2013 GREEN BAY, Wis. (WFRV) - Today 400 dairy leaders from around the state gathered in our area for an annual meeting.

Those farmers were met with protestors in Green Bay.

"In Kewaunee County 30% of the wells tested have tested positive for e. coli and nitrates making it unsafe to drink" says Lynn Utesch a member of Kewaunee CARES.

The citizen group voiced concerns about large farms called "concentrated animal feeding operations" or CAFOs.

They are defined by the state as having 715 or more milking cows.

"The bigger you get the more problems you have. It just produces way too much manure for the land we have in Northeast Wisconsin" says Utesch.
