Book Description
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.

Book Description
Water quality is the physical, chemical and biological characteristics of water. It is most frequently used by reference to a set of standards against which compliance can be assessed. The most common standards used to assess water quality relate to drinking water, safety of human contact, and for health of ecosystems. The vast majority of surface water on the planet is neither potable nor toxic. This remains true even if sea water in the oceans (which is too salty to drink) isn't counted. Another general perception of water quality is that of a simple property that tells whether water is polluted or not. In fact, water quality is a very complex subject, in part because water is a complex medium intrinsically tied to the ecology of the Earth. Industrial pollution is a major cause of water pollution, as well as runoff from agricultural areas, urban stormwater runoff and discharge of treated and untreated sewage (especially in developing countries). This book gathers the latest research from around the globe in this field.

Book Description
The Environmental Monitoring and Assessment Program was created by EPA to develop the capability for tracking the changing conditions of our natural resources and to give environmental policy the advantages ofa sound scientific understanding of trends. Former EPA Administrators recognized early that contemporary monitoring programs could not even quantify simple unknowns like the number of lakes suffering from acid rain, let along determine if national control policies were benefiting these lakes. Today, adding to acidification impacts are truly complex problems such as determining the effects of climate change, of increases in ultraviolet light, toxic chemicals, eutrophication and critical habitat loss. Also today, the Government Performance and Results Act seeks to have agencies develop performance standards based on results rather than simply on levels of programmatic activities. The charge to EMAP of ecosystems is, therefore, the same today as it was a with respect to measuring the condition decade ago. We welcome the increasing urgency for sound scientific monitoring methods and data by efforts to protect and improve the environment. Systematic nationwide monitoring of natural resources is more than anyone program can accomplish, however. In an era of declining budgets, it is crucial that monitoring programs at all levels of government coordinate and share environmental data. EMAP resources are dwarfed by the more than $500 million spent on federal monitoring activities each year.
