U.S. News & World Report looks at how pig farming has gone high tech and is creating new pollution woes. Human waste or industrial discharges must be treated to federal or state clean water standards, but giant hog factories are regulated no differently than small farms, where waste rules are minimal. Last summer, hog wastes were blamed as the major cause of pollution that killed more than 10 million freshwater fish in North Carolina rivers. Wastes from big pig farms also threaten well water and surface water with parasites, bacteria and viruses. (Jan. 22, 1996)
