This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials.Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality.With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. [As taken from Syndetics]

World Water Development Report 4

Electronic copies of the 3 volumes of the 4th edition of the UN World Water Development Report (WWDR4) is now available for download at the UNSECO web page at http://www.unesco.org/new/en/natural-sciences/environment/water/wwap/wwdr/wwdr4-2012/. Publication information about the report describes the WWDR4 as a milestone in the World Water Development Report (WWDR) series. “While providing a comprehensive assessment of the world’s water resources it also introduces a strong thematic element. Building on the WWDR3 in the recognition of the externalities, the WWDR4 elaborates on the interactions between water and the drivers of change. The WWDR4 describes the major changes, uncertainties, and risks taking place in the world and their links to water resources. It gives account of the status and the trends related to water supplies, uses, management, institutions and financing; highlights regional hotspots, and addresses issues such as gender equality, water-related disasters, health and the role of ecosystems.”

longterm Title:  Long-term hazard to drinking water resources from landfills
Editors:  Peter Spillmann, Timo Darrie and Michael Struve

Summary
The co-disposal of domestic waste with industrial waste can represent a serious hazard to prime sources of drinking water throughout the world. Containing the latest research on the risks to groundwater over time, this book provides a scientific case for more sustainable landfill construction – over overwhelming implications for changes in waste management legislation as well as engineering practice. Examining each of the main stages of landfill decomposition and using extensive real-scale testing, the book trades theory for pragmatism and shows just how vulnerable groundwater is to contamination from old ‘dormant’ landfills. It then provides a new method for measuring the extent to which the ingress and egress of water can be controlled in landfill and the associated risks of groundwater contamination. The authors also offer practical suggestions for developing more sustainable and affordable waste management projects. Coverage includes: • Long-term real-scale tests of landfills • Reducing risks to groundwater from old landfills • Aerobic treatment of landfill • Aeration and excavation • Protection of drinking water • Guidance on developing affordable water management projects.

Title:  A simulation tool to assess contaminant warning system sensor performance characteristics
Authors:  Wayne Einfeld, Sean A. McKenna, and Mark P. Wilson

Summary
Water utilities are faced with the ongoing need to provide safe, contaminant-free water to their customers. Contamination sources can include compromised source water that penetrates treatment barriers or intentional contamination attacks from disaffected groups or terrorist organizations. In nearly all contamination event scenarios, early detection and response can help reduce public health risk and impact. To that end, contaminant warning systems offer advantages over more traditional and slower means of contaminant detection and the ability to evaluate various contaminant warning system designs using simulation methods prior to procurement and installation is a desirable capability. The purpose of this project was to develop a simulation tool to assess overall contaminant warning system (CWS) performance under various contamination event scenarios and to incorporate specific sensor performance characteristics in the tool to more realistically assess how sensor operational parameters can influence overall system performance.
