Examines the daunting hurdles facing the EPA in its critical roles in drinking water, air and water pollution, climate change, and toxic chemicals. This book takes the reader on a journey into some of today's most pressing environmental problems: toxic "forever chemicals" known as PFAS, pervasive agricultural pollution, dead zones in the Gulf of Mexico, and widespread air and water pollution from use of fossil fuels. Delving into the science, politics, and human dimension of these and other problems, the book illustrates the challenges of regulation, how today's war on science is undermining the scientific foundation upon which the agency's legitimacy rests, and why a strong U.S. Environmental Protection Agency is more important than ever before.
