Applied Freshwater Ecology explains the study of water quality in a river system. It begins in the field of applied science showing how information is acquired and disseminated. Turning to understanding of the stream system, the book explains the unique properties of water and streams in the landscape of watersheds. The heart of the book covers all aspects of water quality assessment including the physical, chemical and biological monitoring needed to conduct a good survey. The book concludes with explanations of ecology and regulations as they are intertwined into the work of improving our water resources. The book is a good resource for those working in the field of water quality and students learning about this field.

Thomas D. Shahady, Ph.D. is Professor of Environmental Science at University of Lynchburg and Director of the Environmental Education Center focusing on Water Resources in U.S. and Environmental Health in Latin America. He has a Bachelors of Science in Biology and Environmental Studies from Guilford College in Greensboro, NC, a Masters of Science in Environmental Health from University of North Carolina School of Public Health, and a Ph.D. in Zoology with Water Resources Minor from North Carolina State University.
Dr. Shahady has expertise in community based environmental problems. He has researched and consulted on water quality issues in the Finger Lakes Region of New York State, reservoirs throughout North Carolina and Virginia and the impact of urbanization throughout the Chesapeake Bay Watershed. He has worked with industry, EPA, and state regulators on environmental compliance issues. His current work is focused on sound environmental monitoring to manage and improve degraded water quality. He is also focused on how to improve stream restoration and develop good watershed management plans for degraded areas. In Costa Rica, he is working to improve overall sanitation to improve both drinking water and river health. His outreach is helping affected communites monitor their water quality and improve health.
