Overview

Nutrient enrichment of lakes is a ubiquitous problem, impacting ecological and human health on a global scale by accelerating the pace of eutrophication, often resulting in algal blooms, depleted dissolved oxygen concentrations, and economic harm to surrounding communities. In many lakes, bed sediments are a major but unrecognized source of phosphorus to the water, a process known as internal phosphorus loading. Internal loading is notoriously difficult to measure and manage given the need to access processes operating on and within the lakebed. In addition, climate change threatens to promote internal loading. For example, warming of lakes can increase the release of phosphorus from sediments due to 1) longer and stronger periods of lake stratification resulting in sediment anoxia and 2) enhanced microbial decomposition of organic matter. Degraded water quality not only impairs ecological health but also can influence social pride and community morale. This is the first book dedicated to the understanding of internal phosphorus loading in lakes and examines the causes, the ecological and societal impacts, and options for managing this complex phenomenon. With contributions from leading experts, this edited volume provides a broad view of internal phosphorus loading, methods for measurement, management practices for water quality improvement, case studies from around the world, and recommendations for addressing this growing concern. It is essential reading for environmental and engineering professionals involved in lake and reservoir management, students and faculty in limnology, state and federal authorities involved in water quality regulation, and lakefront homeowners and management boards interested in maintaining lake water quality and managing algal blooms. Key Features: First-ever comprehensive volume on internal phosphorous loading that clearly details what it is and why it occurs Identifies and explores the drivers of internal phosphorus loading Provides methods, techniques, and models for measuring internal phosphorous loading Features over 150 color figures and photographs to illustrate important concepts and procedures Includes 17 detailed case studies written by experts from around the world to highlight key research principles, treatment options, and management strategies for major lakes affected by internal phosphorus loading

Author Information

Bryan Spears, Ph.D., is a Principal Scientific Officer with the Freshwater Restoration and Sustainability Group at the Centre for Ecology & Hydrology (CEH), Edinburgh, UK, part of the Natural Environment Research Council. He has worked at CEH since 2007 in which time he has published over 100 scientific articles and research reports. Much of Bryan's work has focused on identifying ecological responses to man-made pressures in inland and coastal waters. These pressures include climate change, industrial pollution, and nutrient enrichment and their interactions. He has managed national scale surveys of biogeochemical cycling in rivers and estuaries in Scotland and initiated a series of whole lake experiments to examine geoengineering in lakes for internal phosphorus loading control in the UK, coordinating international efforts in this field through networking initiatives. In recognition of his contribution to teaching and research, Bryan serves as an Honorary Fellow at the University of Edinburgh, Department of Geosciences, UK. He has supervised 12 Ph.D. students, mostly in the field of lake restoration and biogeochemical cycling in aquatic ecosystems. Bryan serves as an Associate Editor for the journals Inland Waters and the Journal of Environmental Quality and has served as a Guest Editor for the journals Water Research and Hydrobiologia. He is a member of the United Nations Environment Programme's Global Phosphorus Task Team, reporting to the Global Partnership for Nutrient Management, through which he raises awareness of the wide-spread problems caused by phosphorus enrichment of lakes, including the importance of internal loading and its management. Bryan's work on lake restoration has a strong focus on delivering benefits to local communities in the UK and internationally. Bryan, in collaboration with Miquel Lürling, Wageningen University, the Netherlands, co-founded the International Society of Limnology Working Group on Lake Restoration which works collectively to deliver knowledge and expertise to those countries that need it most. Dr Spears holds a Ph.D. in Limnology from St Andrews University, UK; an M.Sc. in Aquatic Ecology from Simon Fraser University, Canada; and a B.Sc. (hons) In Environmental Sciences from Robert Gordon University, Aberdeen, UK. Alan Steinman, Ph.D., is the Director of Grand Valley State University's Annis Water Resources Institute, a position he has held since 2001. Previously, he was Director of the Lake Okeechobee Restoration Program at the South Florida Water Management District. Steinman has published over 175 scientific articles, book chapters, and books; has been awarded over $55 million in grants for scientific and engineering projects; and has testified before the U.S. Congress and the Michigan and Florida state legislatures. Among his awards are Phi Beta Kappa, the 2017 Award of Excellence from the National Garden Clubs, the U.S. Army Corps of Engineers Outstanding Planning Achievement Award, the Joan Hodges Queneau Palladium Medal from the National Audubon Society, Paul Harris Fellow, Keiser Distinguished Lecturer in Life Sciences from Ohio Northern University, and the Patricia B. Johnson Award for Leadership and Innovative Grantmaking from the Community Foundation for Muskegon County. Al is a member of science advisory boards for the U.S. EPA, the International Joint Commission, Michigan DEQ, Sea Grant, Healing our Waters, University of Michigan's Water Center, and the Cooperative Institute for Great Lakes Research. He currently serves as Associate Editor for the journal Freshwater Biology and has served on the State of Michigan's Groundwater Conservation Advisory Council and Phosphorus Advisory Committees. Steinman's research interests include aquatic ecosystem restoration, harmful algal blooms, phosphorus cycling, and water policy.
