Book Description
In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.

Book Description
This paper outlines the concept of buffer zones and proposes a new definition of the term 'watercourse.' It also reviews the widths of buffer zones, and the activities permitted within those zones, as proposed for establishment under Prince Edward Island regulations. Policies for management of forested stream buffers and for highway construction and maintenance are also proposed.

Book Description
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Description
New Brunswick's Clean Water Act requires 75-meter-wide buffer zones along banks of all watercourses in municipal water supply areas. These regulations are new and need to be tested. This report presents case studies from a project which sought improvements in the underlying rationale for buffer zone width and management. The case studies were used to seek answers to two questions crucial to the project: whether timber harvesting could be carried out within buffers without detriment to water quality, and whether the remaining forests responded in a manner favorable to watercourse protection and future yield. The case study sites were chosen to represent different ecoregions of the province. Information in the case study reports includes terrain and forest condition, harvesting conducted, buffers established, and water quality. The report ends with a discussion of significant factors revealed by the case studies, such as wind hazard.
