In this June, 28, 2012 photo, a portion of the livestock being raised by hog farmer Robert Young mill around in the climate-controlled hog barn on Young's family farm in Buckhart, Ill. Four years after the U.S. Government Accountability Office raised concerns and 40 years after the Clean Water Act gave the EPA the authority to protect the nation's waterways, the agency still doesn't know the location of many livestock farms, let alone how much manure they generate or how the waste is handled, because most of that information is kept by various state and or local agencies _ or not collected at all.
