When deformed frogs-many with missing legs or eyes, footless stumps, or misshapen jaws-began to emerge from Minnesota wetlands, alarm bells went off. What caused such deformities? Pollution? Ultraviolet rays? Biological agents? And could the mysterious cause also pose a threat to humans? Former government biologist Judy Helgen provides an inside view of a highly charged environmental issue that continues to spark controversy among scientists, politicians, and government agencies.

Over the past decade, interpretations of Supreme Court (SC) rulings removed some critical waters from Fed. protection, and caused confusion about which waters and wetlands are protected under the CWA. As a result, important waters now lack clear protection under the law. This draft guidance clarifies how the EPA and the U.S. Army Corps of Engineers (ACE) will identify waters protected by the CWA and implement the SC¿s decisions concerning the extent of waters covered by the Act. It clarifies how the EPA and the ACE understand existing requirements of the CWA and provides guidance to agency field staff in making determinations about whether waters are protected by the CWA. This is a print on demand report.
