Assessment and control of nonpoint source pollution of aquatic ecosystems

the long version

"Why is nonpoint source pollution a problem? What topics are most important to the policy-maker? What are the characteristics of nonpoint source pollution? What factors affect its extent? What human activities and land uses are involved?" "These are among the questions addressed by a multi-national team of authors in this book. The aim is to review existing knowledge and experience regarding the assessment and control of nonpoint source pollution, and bring this knowledge together in a form that is useful for both scientific and management purposes. The book is not meant to be an extensive technical treatise, but rather to provide sufficient information to allow interested persons to acquire a broad, general knowledge of the assessment, causes and control of nonpoint source pollution."--Jacket.
