Today in Texas, over 1500 colonias in the counties along the Mexican border are home to some 400,000 people. Often lacking basic services, such as electricity, water and sewerage, fire protection, policing, schools, and health care, these "irregular" subdivisions offer the only low-cost housing available to the mostly Hispanic working poor. This book presents the results of a major study of colonias in three transborder metropolitan areas and uncovers the reasons why colonias are spreading so rapidly. Peter Ward compares Texas colonias with their Mexican counterparts, many of which have developed into fully integrated working-class urban communities. He describes how Mexican governments have worked with colonia residents to make physical improvements and upgrade services-a model that Texas policymakers can learn from, Ward asserts. Finally, he concludes with a hard-hitting checklist of public policy initiatives that need to be considered as colonia housing policy enters its second decade in Texas.

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.

Encompassing papers form the 2019 Water and Society Conference, this book is a collection of latest trans-disciplinary research on issues related to the nature of water, and its use and exploitation by society. This book demonstrates the need to bridge the gap between specialists in physical sciences, biology, environmental sciences and health. Over the centuries, civilisations have relied on the availability of clean and inexpensive water. This can no longer be taken for granted as the need for water continues to increase due to the pressure from growing global population demanding higher living standards. Agriculture and industry, major users of water, are at the same time those that contribute to its contamination. Water distribution networks in urban areas, as well as soiled water collection systems, present serious problems in response to a growing population as well as the need to maintain ageing infrastructures.Many technologically feasible solutions, such as desalination or pumping systems are energy demanding but, as costs rise, the techniques currently developed may need to be re-assessed. The research contained in this book addresses the interaction between water and energy systems.The socio-political implications of a world short of clean, easily available water are enormous. It will lead to realignments in international politics and the emergence of new centres of power in the world.The following list covers some of the subjects included in this book: Water resources management; Agribusiness; Water as a human right; Water quality; Water resources contamination; Sanitation and health; Water and disaster management; Policy and legislation; Future water demands; Irrigation and water management; Management of catchments; Groundwater management and conservation.

Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

"A properly designed, constructed and maintained storage tank that is filled with treated drinking water should be capable of providing water that is safe to drink for the full duration of time the water remains in storage and distribution. Poorly-designed water storage, lack of regular inspections, improper cleaning and repair of drinking water storage tanks can pose serious health and safety risks to users/ consumers, increasing the risk of water contamination and/or water quality deterioration during storage"--Introduction, page 2.

This contributed volume covers a comprehensive account of the sources, toxic biological as well as environmental impacts, and possible remediation strategies for contamination by heavy metals. In biological systems, toxic metals affect the integrity of cellular organelles and act as carcinogens causing chromosomal aberrations or as systemic toxicants leading to cardiovascular, neurobehavioral, and immunological disorders. In plants, they interfere with photosynthesis, fertility, metabolite, and chlorophyll synthesis. Toxicity induced by heavy metals involves mechanistic approaches that need to be understood properly. They cannot be degraded by biological or chemical means and thus can only be converted to less harmful forms. The conventional detection methods include biosensors, voltammetry, atomic absorption spectrometry, and inductively coupled plasma with atomic emission spectrometry. All such strategies for metal detection and mitigation strategies are covered in this title under one section. This book incorporates classical views along with modern scientific approaches to develop an understanding of the subject matter suitable for academicians, researchers, planners, policymakers, NGOs, and environmental consultancies and raise awareness on this concern. Topics representing diverse sections namely environmental impacts, biological effects, and methods used for detection and remediation have been included to address all possible contemporary issues on the topic in one concise volume.

The water storage system is a critical component in the multiple-barrier approach to safeguarding water supplies. Storage facilities have a significant effect on the quality of water that flows through the distribution system and on to the customer's tap. Unfortunately, storing water can also lead to the degradation of a water supply. Excessive water age causes problems such as microbial growth and chemical changes in the water.
