Restoring Life in Running Waters
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 ...
Biological Assessment and Criteria
Biological Assessment and Criteria presents a state-of-the-art overview of the applications of biological assessments and biocriteria for water quality management in fresh waters. The book presents case studies which illustrate how bioassessment has been used to identify and diagnose water quality problems. It also provides examples of the use of qualitative and quantitative biocriteria as regulatory tools to complement water quality criteria and standards. The first book to present the technical foundation, rationale, program and policy relevance, and legal basis for the most accurate tools used to assess freshwater natural resource and regulatory efforts, this book provides useful and timely information for water quality managers.

Living in Integrity
This innovative book takes a new look at environmental ethics and the need for ecological and biological integrity. Laura Westra explores the necessity for radical alteration not only of interpersonal ethics, but also of social institutions and public policy. In the process, Westra denies the validity of majority rule in environmentally ethical concerns. Issues discussed in the book include the link between ecological integrity and human health; an environmental evaluation of business and technology; biotechnology and transgenics in agriculture and aquaculture; and the environmental ethics of the ancient Greeks and Kant. Living in Integrity is a valuable book for philosophers and environmentalists alike.
