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.

Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

If you work in the water quality management field, you know the challenges of monitoring and controlling pollutants in our water supply. The increasing problem of agricultural nonpoint source pollution requires complex solutions. Agricultural Nonpoint Source Pollution: Watershed Management and Hydrology covers the latest techniques and methods of managing large watershed areas, with an emphasis on controlling non-point source pollution, especially from agricultural run-off. Written by leading experts, the book includes topics such as: nitrate and phosphorus pollution, pesticide contamination, erosion and sedimentation, water-table management, and watershed management. The authors discuss the effects of agricultural run-off - one of the most intransigent problems now faced by environmental engineers and hydrologists. They explore each issue with an eye towards the integrated management of water quality and water resources over a defined area or region. This single-source reference gives you a complete understanding of the whats, whys, and hows of nonpoint source pollution - and more importantly of how to monitor and manage it. Agricultural Nonpoint Source Pollution: Watershed Management and Hydrology provides a broad but detailed overview that helps you to comprehend the intricacies of the problem and puts you on the path to finding the answers.

"Presents and compares all major stormwater/runoff control strategies ; New data on pollutant removal efficiencies, design, costs, environmental impacts and more ; Where and why to use the best techniques for limiting/monitoring diffuse pollution ; Provides the tools to meet regulations and improve water quality in urban/suburban watersheds"--From publisher's description.

Over 1.6 million miles of dirt and gravel roads exist within the United States providing a vital part of the nation's transportation system. An environmentally sensitive road maintenance practice is a practice that when implemented reduces the adverse effect of a road on the environment by treating the cuase of the problem and is in keeping wtih the natural landscape. This illustrated field guide provides examples of environmentally sensitive maintenance practices, which if implemented reduce erosion and sediment, maintain subsurface hydrologic connectivity, restore drainage density to more natural conditions, and eliminate diversion potential. It is organized to identify visual signs and problems associated with CAUSES and SOLUTIONS for the most commonly encountered road problens (road surface, ditch, cutbank, etc.) Highway inspectors, public works construction inspectors, to include some construction and building inspectors and engineers that must meet compliance with specifications, building codes, and other regulations, Additionally, City engineers, concrete masonry contractors, road maintenance specialists and workers, and technicians, as well as County Road Supervisors may ber interested in this volume. Students pursuing degree programs for Civil Engineering or certificates of study for Industrial Maintenance Technology or Public Works training in clases such as Roadway Asset Management Essentials, or Inspecting Pavement Markings or certified Public Infrastructure Inspector courses may be interested in this print field guide as a handy reference.

This guide shows you how to develop and implement a Storm Water Pollution Prevention Plan specifically designed for your construction site. It should answer any questions you have regarding the NPDES General Permit for Storm Water Discharges from Construction Activities that are classified as "Associated with Industrial Activity" (referred to as EPA's Baseline Construction General Permit). Step-by-step guidelines and checklists walk you through the process of setting up your plan, which makes the book invaluable for consultants, regulators, and construction managers and engineers.
