Treatment Marshes for Runoff and Polishing

Treatment wetlands encompass a large diversity of managed ecosystems, and provide an impressive array of water quality improvement mechanisms. This book explains how to calculate the pollutant removal performance of water treatment marshes, which are used for waters that are only lightly polluted.

Treatment Marshes for Runoff and Polishing represents the most comprehensive and up-date-date resource for the design, construction, and operation of marsh treatment systems.

This new edition represents a complete rewrite of the surface flow sections of previous editions of Treatment Wetlands. It is based on the performance hundreds of treatment marshes over the past 40 years. Treatment Marshes focuses on urban and agricultural runoff, river and lake water improvement, and highly treated municipal effluents.

New information from the past dozen years is used to improve data interpretation and design concepts. Topics included in this book are






Diversity of marsh vegetation



Analyses of the human use of treatment marshes



New concepts of underground processes and functions



Spectrum of marsh values spanning mitigation, restoration, enhancement, and water quality improvement



Improved methods for calculation of evapotranspiration and wetland water temperatures



Hydraulics of surface and subsurface flows in marshes



Analysis of long track records for deterministic and probabilistic behavior



Consideration of integrated microbial and vegetative contaminant removals via mass balances



Uptake and emission of gases



Performance of urban and agricultural wetlands



Design procedures for urban and agricultural wetlands



Reduction of trace metals, pesticides, pharmaceuticals, endocrine disruptors, and trace organics



Updated capital and O&M economics, and valuation of ancillary benefits



An updated list of over 1900 references
