BIOREMEDIATION TO THE PIGPEN It was a stinky summer at the EnviroPork hog facility near Larimore, N.D., with penalties pending for violating state odor regulations, and neighbors complaining loudly about the foul fragrance. Making matters worse, the manure lagoon associated with the facility threatened groundwater supplies. Happily, researchers from the University of North Dakota Energy and Environmental Research Center (EERC) had a low-tech solution: barley straw. Using a cannon, they shot a
