Hogs and economic miracle or environmental disaster?
Housing thousands of animals, a typical hog farm generates sewage waste equivalent of a small town. Gaseous pollutants and odor are released into the atmosphere, while both solid and liquid hog wastes are pumped into lagoons, liquefied hog waste is regularly sprayed onto nearby agricultural land, much of which is close to homes, schools, churches and businesses. Even when operating as permitted, runoff contaminates surface and ground water.
