North Carolina's ten million hogs produce twice as much feces and urine as the populations of the cities of Los Angeles, New York and Chicago combined. Industrial farms, most with thousands of hogs each, store the waste in open-air pits, called lagoons. They spray the waste, untreated, as manure on adjacent fields.

Neighbors say the stench can be unbearable. The Morning Star Baptist church in Battleboro is about half a mile from a large hog farm. Evelyn Powell runs the church day care center.

EVELYN POWELL: The kids say it stinks out there. They get nauseous, they get sick when it is at a high pitch, and they are unable to go outside and play and enjoy our quality of life at the day care.

McARTHER KING: I like to walk everyday, but sometimes I come out, I can't even walk because the odor is so bad.

JEFFREY KAYE: Powell calls the lagoons "open air toilets," and notes residents have to keep their septic tanks covered.

EVELYN POWELL: The hog farmers can open theirs up and just be a great big football field full of manure all day long and we are supposed to smell it and accept it. I think it should be unconstitutional to mess up somebody's community, the way they have messed ours up.

JEFFREY KAYE: Environmental activists such as Rick Dove of the Riverkeeper Alliance charge that pig waste creates more than just a stink.

RICK DOVE: The land that you're looking at is also very poorly suited for this kind of operation.

JEFFREY KAYE: Dove takes visitors on aerial tours of industrial pig operations. The farms, concentrated in the eastern part of the state, produce more manure than the land can absorb, according to the U.S. Department of Agriculture. Dove often spots pig waste from sprayers being spread on saturated fields, running off into waterways.

RICK DOVE: Wetlands normally process nutrients, and they're the place where the algae grows. They're sort of the filters of the water before it's released to the ocean. The problem is though, you're looking at wetlands that are completely overburdened. These wetlands are being worked to death trying to process these nutrients that run off these hog factories.
