No one has recorded when well digging started, but surely humans imitated elephants in digging holes in the sand to access cooler water that didn’t make the children sick. Eventually, humankind began to redesign, maintain, and repair the wells they constructed, but when wells became "commodities" in the twentieth century, this maintenance ethic was fogotten. Recapturing that ethic, Sustainable Wells: Maintenance, Problem Prevention, and Rehabilitation is a guide to keeping well systems operating at peak capacity. The book focuses on how to prevent and forestall problems, and manage the problems with wells as they age. Examining the many challenges that come with maintaining well performance, the book provides a comprehensive yet readable state-of-the-art summary of performance maintenance, problem prevention, and rehabilitation or restoration practice with the goal of sustaining optimal performance over the long run. Rather than focusing on a certain aspect of well cleaning, or a particular technical approach, it covers the scope of maintenance and rehabilitation, from planning to evaluation testing. It also addresses the crucial subjects of preventive design, maintenance monitoring from electrical to biofouling, and evaluation testing. An exploration of the subject without a vendor or strong regional bias, the book is based on the authors’ extensive hands-on experience serving well-operating clientele. In addition to water supply wells, it addresses the problems and maintenance issues of monitoring, plume control, and other "environmental" wells. Compiling information from existing literature into a single source, and combining that information with experience, the book provides recommendations based on historical performance. Copiously illustrated with approximately ninety black and white photographs, figures, and a color insert, the book reflects the changes in the profession that have occurred during the past decade or so. These features and more make this the first resource to turn to when devising solutions for maintaining and improving well performance.

Blueprint for Green Affordable Housing is a guide for housing developers, advocates, public agency staff, and the financial community that offers specific guidance on incorporating green building strategies into the design, construction, and operation of affordable housing developments. A completely revised and expanded second edition of the groundbreaking 1999 publication, this new book focuses on topics of specific relevance to affordable housing including: how green building adds value to affordable housing the integrated design process best practices in green design for affordable housing green operations and maintenance innovative funding and finance emerging programs, partnerships, and policies Edited by national green affordable housing expert Walker Wells and featuring a foreword by Matt Petersen, president and chief executive officer of Global Green USA, the book presents 12 case studies of model developments and projects, including rental, home ownership, special needs, senior, self-help, and co-housing from around the United States. Each case study describes the unique green features of the development, discusses how they were successfully incorporated, considers the project's financing and savings associated with the green measures, and outlines lessons learned. Blueprint for Green Affordable Housing is the first book of its kind to present information regarding green building that is specifically tailored to the affordable housing development community.

Groundwater has provided great benefits to agriculture irrigation in semi-arid OECD countries, but its intensive use beyond recharge in certain regions has depleted resources and generated significant negative environmental externalities.

Water Wells and Boreholes focuses on wells that are used for drinking, industry, agriculture or other supply purposes. Other types of wells and boreholes are also covered, including boreholes for monitoring groundwater level and groundwater quality. This fully revised second edition updates and expands the content of the original book whilst maintaining its practical emphasis. The book follows a life-cycle approach to water wells, from identifying a suitable well site through to successful implementation, operation and maintenance of the well, to its eventual decommissioning. Completely revised and updated throughout, Water Wells and Boreholes, Second edition, is the ideal reference for final-year undergraduate students in geology and civil engineering; graduate students in hydrogeology, civil engineering and environmental sciences; research students who use well data in their research; professionals in hydrogeology, water engineering, environmental engineering and geotechnical engineering; and aid workers and others involved in well projects.

'This is an immensely useful and important book. By applying sustainability theory and practice to all areas of business management for firms of all sizes it has the potential to make a significant difference to the long term viability of businesses and the societies in which they operate.' – Juliet Roper, The University of Waikato, New Zealand Recent surveys of international CEOs confirm that companies increasingly see sustainability as critical to their business strategy. The rigorous academic framework for the field of sustainable business required to respond to this need is now emerging. This book presents important new work in the theory of the sustainable firm, in the application of sustainability principles to key management disciplines, in sustainable business in practice, and in the international challenges that are critical to sustainability demands. Sustainable Business will prove invigorating for both undergraduate and graduate students on business, society and sustainability themed courses. Policymakers and practitioners will find the urgent global sustainability issues and sub-disciplines essential.

Balochistan’s agriculture and related economic development during the last four decades has been driven by an enhancement in canal command areas and widespread use of tubewells. While it enabled yield increases and the growth of high value horticulture, it led to excessive mining of ground water. It is not only threatening sustainable agriculture and livelihoods but also creating severe environmental repercussions. It is generally believed that this unchecked groundwater extraction has been a result of policy regime, such as promoting installation of tubewells through various incentive schemes and tubewells subsidy which allows farmers to pay only 5-10% of the actual cost, and as a result the Federal and provincial governments have been paying PKR 23 billion per year.
