Book Description
The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Book Description
This book is part of a two-volume set that offers an innovative approach towards developing methods and tools for assigning conservation categories of threatened taxa and their conservation strategies by way of different phases of eco-restoration in the context of freshwater river systems of tropical bio-geographic zones. The set provides a considerable volume of research on the biodiversity component of river ecosystems, seasonal dynamics of physical chemical parameters, geo-hydrological properties, types, sources and modes of action of different types of pollution, river restoration strategies and methodologies for the ongoing ecological changes of river ecosystems. Volume 2 highlights biodiversity potential in aiding the resistance and resilience of riverine ecosystem functioning and their synergistic effects on ongoing environmental perturbations. Comprehensive information on the conservation of river-associated-wildlife is provided, covering the impacts of pollution, land-use changes, river policies, and ecosystem restoration strategies. The book offers an innovative approach towards developing methods and tools for assigning conservation categories of threatened taxa, and covers their conservation strategies by way of different phases of eco-restoration in the context of freshwater river systems of tropical bio-geographic zones.

Book Description
Despite nearly three decades of efforts intended to protect the nation's waters, and some success against certain forms of chemical and organic contamination, many of our nation's waterways continue to be seriously degraded. The call of the 1972 Clean Water Act -- "to restore and maintain the chemical, physical, and biological integrity of the Nation's waters" -- remains unanswered. Restoring Life in Running Waters discusses freshwater ecosystems in the United States and the need for using biology to understand their present condition. The book makes a case for using indexes that integrate measurements of many biological attributes to assess and communicate environmental health. In a unique and innovative format, the authors present 37 premises and 7 myths that explore the theory and practice of biological monitoring and the use of multimetric indexes. The book explains: why biological monitoring and assessment are needed the historical evolution of biological monitoring how and why living systems give the best signals for diagnosing environmental degradation what multimetric indexes do and why they are effective how multimetric indexes can be used and common pitfalls to avoid in using them why many criticisms of biological indexes are not valid how the principles of biological monitoring and multimetric indexes can be expanded beyond aquatic systems to other environments how information from indexes can be integrated into the regulatory and policy framework Restoring Life in Running Waters provides practical and effective tools for managers and scientists seeking to understand the impact of human activities on natural systems and to determine proper action to remedy problems. It is an essential handbook for conservation biologists; agency personnel at all levels, including technical staff, policymakers, and program managers; and for anyone working to protect and restore the health of the nation's waters.
