Almost 5 years ago we began working together on research for the U.S. Environmental Protec tion Agency (EPA) to measure the benefits of water quality regulations. EPA had awarded a contract to Research Triangle Inst~ute (RTIl in response to a proposal that Bill wrote on measuring these benefits. After meeting with the EPA project officer, Dr Ann Fisher, the basic outlines of what would become this research were framed. Upon the suggestion of Bob Anderson, then chief of the Benefits Branch at EPA, we selected the Monongahela River as the focal point of a case study that would compare alternative benefit measurement approaches. Exactly how this case study would be done remained vague, but Ann urged that there be a survey and that nonuse benefits be included in the question naire design. Of course, Bill agreed. At the same time, Kerry was independently working on a review article that tied together some of the loose threads in the option value literature. He had also been thinking about how to measure option value, as well as working on ways to generalize the travel cost approach for estimating benefits of site attributes. Glenn Morris at RTI suggested that Bill have lunch with him and Kerry and that they could talk about Bill's research to see if there were any mutual interest. Over the lunch and Bill's ever present dessert in a Chapel Hill restaurant, we found out just how much we have in common.

Water Quality Monitoring and Management: Basis, Technology and Case Studies presents recent innovations in operations management for water quality monitoring. It highlights the cost of using and choosing smart sensors with advanced engineering approaches that have been applied in water quality monitoring management, including area coverage planning and sequential scheduling. In parallel, the book covers newly introduced technologies like bulk data handling techniques, IoT of agriculture, and compliance with environmental considerations. Presented from a system engineering perspective, the book includes aspects on advanced optimization, system and platform, Wireless Sensor Network, selection of river water quality, groundwater quality detection, and more. It will be an ideal resource for students, researchers and those working daily in agriculture who must maintain acceptable water quality. - Discusses field operations research and application in water science - Includes detection methods and case analysis for water quality management - Encompasses rivers, lakes, seas and groundwater - Covers water for agriculture, aquaculture, drinking and industrial uses

This volume describes the methods used in the surveillance of drinking water quality in the light of the special problems of small-community supplies, particularly in developing countries, and outlines the strategies necessary to ensure that surveillance is effective.

This guidebook, now thoroughly updated and revised in its second edition, gives comprehensive advice on the designing and setting up of monitoring programmes for the purpose of providing valid data for water quality assessments in all types of freshwater bodies. It is clearly and concisely written in order to provide the essential information for all agencies and individuals responsible for the water quality.

This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.
