Chicken Litter: The Aerial Hunt for Poultry Manure

Ocean City, Md.

Retired Marine officer Rick Dove boarded the four-seat Cessna armed with cameras, binoculars and global positioning devices for his latest mission: chicken farmers. Or, more precisely, aerial reconnaissance of poultry droppings.

"Oh, man, that looks like a hot site," Mr. Dove said as the plane soared 1,000 feet over farms near the Chesapeake Bay. Peering through binoculars, he said, "That pile is at least two stories high." He whipped out his camera and started snapping pictures.

Mr. Dove, 70 years old, suspected the brown mound was chicken manure -- a potential pollutant of the Chesapeake Bay, the huge estuary nestled between the shores of Maryland and Virginia. Mr. Dove, a former military judge whose subsequent fishing business he believes was ruined by pollution, is among the activists who, along with federal regulators, are ratcheting up pressure on poultry farmers to clean up their litter.

Livestock and poultry operations generate about 500 million tons of manure each year, or about three times the amount of human waste in the U.S., according to the Environmental Protection Agency. Much of that waste goes untreated and sometimes can make its way into public waterways. Among other contaminants, manure contains nitrogen and phosphorus that in large quantities can cause algae blooms -- green, gooey splotches on the water surface that can deplete the water's oxygen, killing fish and other organisms. And in some cases, the runoff, which can contain E. coli and other bacteria, can threaten human health.
