The Scary New Math of Factory Farm Waste
One CAFO can produce as much manure as a medium-size city in the United States — with one critical difference: A medium-size city in the U.S. is required under the Clean Water Act to have a municipal wastewater treatment plant. CAFOs have no such treatment plant.
INDEPENDENT MEDIA INSTITUTE: ‘It has been almost a year since Hurricane Florence slammed the Carolinas, dumping a record 30 inches of rainfall in some parts of the states. At least 52 people died, and property and economic losses reached $24 billion, with nearly $17 billion in North Carolina alone. Flood waters also killed an estimated 3.5 million chickens and 5,500 hogs.
A lesser-known impact of the devastating hurricane was revealed through satellite photos released after the storm. Excessive rainfall flooded concentrated animal feeding operations (CAFOs) in low-lying areas, carrying riverbed sediment and animal waste previously stored in open-air lagoons into nearby waterways and then into the Atlantic. The difference between the photos, taken just five months apart before and after the storm, is striking.
Generally, CAFOs dispose of animal waste by spraying it as fertilizer and storing the excess in massive underground pits or open-air lagoons, where sulfur-eating bacteria often turn the mixture bright pink. Given that cropland can absorb only so much, a good deal of the waste ends up in groundwater, rivers, streams and the ocean. In fact, agriculture is the leading cause of pollution in the nation’s rivers and lakes, according to the U.S. Environmental Protection Agency (EPA), much of it emanating from large-scale factory farms.
Floods can have even more devastating consequences for water quality. The risk is particularly pressing for North Carolina, a state regularly smacked by hurricanes, because it houses more than 2,200 hog CAFOs and 3,900 poultry CAFOs, and produces up to 10 billion gallons of animal waste a year. These estimates come from the Environmental Working Group (EWG). One problem is that they are just that — estimates.
The truth is no one really knows how much factory farm waste is escaping into our environment because no federal agency collects consistent and reliable information on the number, size and location of large-scale agricultural operations, nor the pollution they’re emitting. This means there is considerable variation on how thoroughly states track and monitor CAFOs. Without this information, no one can monitor and hold CAFOS accountable for mismanaged waste and related health and environmental damage…
The health and environmental impact of CAFOs is indeed enormous. “CAFOs are large-scale facilities that house thousands if not tens of thousands of animals in very small spaces,” said Ho. “One CAFO can produce as much manure as a medium-size city in the United States” — with one critical difference: A medium-size city in the U.S. is required under the Clean Water Act to have a municipal wastewater treatment plant. CAFOs have no such treatment plant’. SOURCE…
