If you are a fly-fisher, a rafter, or heck, just a person who drinks water, here is some troubling news: Our waterways are in rough shape. An eye-opening new report (PDF) from Environment America Research and Policy Center finds that industry discharged 226 million pounds of toxic chemicals into America's rivers and streams in 2010. The pollution included dead-zone-producing nitrates from food processors, mercury and other heavy metals from steel plants, and toxic chemicals from various kinds of refineries. Within the overall waste, the researchers identified 1.5 million pounds of carcinogens, 626,000 pounds of chemicals linked to developmental disorders and 354,000 pounds of those associated with reproductive problems.

They all basically told me the same thing: "All discharges meet permit requirements," Cargill said. "This is a natural process that is fully licensed, and included as part of our wastewater discharge reporting," echoed McCain Foods.

We'll have to take their word for it, since the companies are not required to release the results of their chemical safety testing to the public, nor do they have to reveal how much of each chemical they are releasing. The Clean Water Act doesn't even apply to all bodies of water in the United States; exactly how big and important a waterway must be to qualify for protection has been the subject of much debate. Rivers get the big conservation bucks; they're the waterway equivalents of rhinos and snow leopards. But pollutants in oft-neglected ditches, canals, and creeks—the obscure bugs of the waterway world—also affect ecosystems and our drinking water quality.
