An excerpt from the opening of the article should suffice to get you over there to read it:
A “Cow Palace” in Washington State threatens public health with its acres of untreated animal waste.
A city in Iowa spends nearly $1 million a year to keep illness-causing nitrates, generated by farm runoff, out of public drinking water.
And who can forget the plight of Toledo, Ohio, residents whose water last summer was so contaminated by farm runoff that they couldn’t even bathe in it, much less drink it?
For decades, America’s chemical-intensive, industrial farming operations have spewed nitrates and other toxic chemicals, animal waste, ammonia, antibiotics, carbon dioxide, nitrous oxide and methane gases into public air, waterways and communities.
How do they get away with it? Largely because lobbyists have seen to it that Big Ag is exempt from many of the rules and regulations that other industries, and even municipalities, are required to follow under the Clean Air Act (comments on exemptions here), the Clean Water Act (comments on exemptions here), the Resource Conservation and Recovery Act (RCRA), the Safe Drinking Act, and others.
