There have been very few, if any, books of a practical nature covering the 'art' of drilling holes in the ground especially for water. Some rather lengthy tomes are and have been available over the years which have been pretty well incomprehensible to the average field man, or indeed, those responsible for the administration of field operations. Most of those books have been written by people with peripheral disciplines to the industry thus haven't had the field experience to really get hold of the heart of the matter. Drilling for Water - 2 has been written to be understandable to field personnel and in their own terms. Everything in it is based on considerable field experience. Following the publication of Drilling for Water, many accolades were forthcoming such as ...packed with information... ...my bible... ...most welcome... ...a breath of fresh air... ...couldn't put it down... etc.

In a simple, straightforward manner, this book presents most of the major process units for wastewater treatment, addressing what the unit is and how it basically works. Along with that it provides some of the math problems associated with each unit. Each math problem, presented in English units, is usually followed by a nearly identical problem in metric units. It also presents new concepts, such as information on process microbiology, in a comfortable language so the reader can concentrate on the subject matter instead of the language used to present it. Simplified Wastewater Treatment Plant Operations provides comprehensive and technically accurate wastewater information in a clear and concise manner. The related workbook provides readers with a place to write in answers and work out problem solutions.

Our interpretations of the world we live in, and the people and institutions that comprise it, are acquired through complex interactions among what we believe to be true, what the world is, and/or what others think it is. Understanding those complex interactions is one of the most important goals of the social sciences. Of the many disciplines that have contributed to that understanding, two take center stage in this book -- psychology and communication. This volume's purpose is to reconnect the partially isolated environments of social psychology and communication. To do so, it utilizes four building blocks: * the cognitive foundations of interpersonal communication as it might be studied from a social psychological perspective * insiders' views of interpersonal communication from a cognitive psychological standpoint * insiders' approaches to interpersonal communication from an AI perspective * a critique of the cognitive enterprise that reflects the strong philosophical grounding of communication. Overall, the chapters typify some of the most interesting cognitive work done in the study of interpersonal communication. As such, the book should promote productive dialogue across disciplinary boundaries and stimulate further work within the field of interpersonal communication.

Lack of clean water is one of the most important public health challenges in less developed communities. Due to insufficient financial and technical resources in places in need, development of low-cost water treatment technologies can play a key role in sustainable water provision. In this context, this PhD research investigated the removal of pathogenic microorganisms in simple sand filtration set-ups supplemented with low-cost adsorbents (hydrochar) produced via hydrothermal carbonization of biowastes. Two types of hydrochar, derived from hydrothermal carbonization of agricultural residue of maize and stabilized sewage sludge from wastewater treatment plant, were evaluated as adsorbents for Escherichia coli removal in saturated sand columns. The removal efficiency of sand columns amended with these adsorbents improved from 20-70% to ~90 % by alkali activation carried out in room temperatures using 1 M potassium hydroxide solution. This PhD research also demonstrates the removal of human pathogenic viruses in sand columns supplemented with hydrochar adsorbents derived from stabilized sewage sludge and fresh swine waste. In order to enumerate human pathogenic rotavirus and adenovirus in virus removal experiments, low-cost polymerase chain reaction assays were developed under this PhD study. These assays show a competent performance in analyzing virus concentrations in both laboratory and environmental samples. Amendment with either hydrochar (without alkali activation) in sand columns was able to remove more than 99% of both viruses.

Selenium is an intriguing element as on one hand it is toxic and on the other hand it is a necessary micro-nutrient for humans. It is also a desirable element due to its unique properties and hence it is used in xerogrpahy, rectifiers, solar cells etc. The presence of selenium in agriculture, acid-mine drainage wastewaters is known and their remediation is necessary. Since, selenium is not mined anywhere, it is important to recover the selenium from waste streams. Bio-remediation of selenium containing wastewater is not only efficient but it also gives insight into the fate of selenium in the bioreactors and environment, thus improving the recovery efficiencies. However, there are still many unknowns in the fate of the selenium present in the wastestreams when treated using microbial processes. One of the biggest unknown is the characteristics of biogenic colloidal elemental selenium nanoparticles (BioSeNPs). These BioSeNPs are present in the bioreactors and are colloidal in nature, hence, present in the effluent of the reactor. BioSeNPs are also known to have the coating of organic polymer on its surface, however the origin of these coating are not known. Moreover, these BioSeNPs are always spherical in shape which is desirable in some cases and not so desirable in many. Furthermore, these BioSeNPs are produced extracellularly and also intracellularly, however the effect of the BioSeNPs' trapping in the biomass is not well understood. This book throws light on the above questions and improves our fundamental understanding on the characteristics and fate of BioSeNPs in the bioreactors and environment. This book also uses the fundamental knowledge to improve the bioremediation process and recoverability of selenium. This study demonstrates that extracellular polymeric substances (EPS) are capping the BioSeNPs and thus providing them colloidal stability and hence mobility, which is in contrast to our conventional understanding on the role of EPS in metal(loid) nanoparticles mobility. All the produced BioSeNPs are known to be spherical but nanowire shape is important to understand their fundamental properties and application. Thus, this study produced biogenic selenium nanowires by reduction of selenite by simply using thermophilic temperatures (55 and 65 oC) and characterized them for their magnetization properties. The practical applications of BioSeNPs were explored by preferentially adsorbing heavy metals in the following order: Cu>Zn>Cd. The development of one-step process for selenium oxyanions removal and BioSeNPs recovery using thermophilic UASB reactor and activated sludge process was attempted. Thermophilic reduction of selenate in an upflow anaerobic sludge blanket (UASB) reactor showed better retention of BioSeNPs and thus, higher total selenium removal as compared to mesophilic reactor. The aerobic reduction of selenite using activated sludge also showed better retention of BioSeNPs, however, continuous operation of the reactor was not achieved. The selenite fed activated sludge trapping BioSeNPs showed improved settling properties and hydrophilicity as compared to control sludge.

The principle of transferable groundwater rights is that by making water rights capable of being traded in the market, water resources can be used more sustainably and efficiently. Groundwater would achieve its economic value, by switching from the high volume-low value irrigation, which is prevalent with many farmers, particularly in South Asia, to low volume-high value urban supply or the growing of intensive horticultural or cash crops. This book discusses transferable groundwater rights in their broader context. It starts with a detailed description of the physical aspects of groundwater, which non-technical readers should find useful, followed by a discussion of legal and economic aspects. Water transfers and the international experiences in transferable groundwater rights are dealt with in detail in two subsequent chapters. A model is presented to guide those involved in water resources management and planning in their decision process to introduce transferable groundwater rights and water rights trading. The author concludes that transferable groundwater rights potentially offer a better alternative to land-based water rights systems. However, he casts serious doubt on whether groundwater rights trading on its own can achieve water resources sustainability, environmental protection and social equity. Government intervention seems to be almost always needed to assist the water rights market and take responsibility for any of its adverse consequences.

Examining the water, development and security linkages in Central Asia can feel a bit like solving a Rubik's cube. The Rubik's cube starts to usually find structure and the different pieces find their places when its solver adopts a systematic approach. Still, solving the whole cube takes time and perseverance. This is also the case with water and security in Central Asia as demonstrated by the chapters in this book. In the case of water and security in Central Asia, there are many "faces", including not only the Central Asian states but also the neighbouring countries and other players of global geopolitics; "stickers" such as policies, practices, causes, and impacts; and "colours" such as the different stakeholders, ranging from the micro and meso levels to the macro level. Understanding all these, or getting clarity on the nexus, can seem extremely challenging. Even though none of the chapters alone answers the question of what constitutes water and security in Central Asia, each of them gives thoughtful ideas and information on the complexity of the issue. This book was published as a special issue of the International Journal of Water Resources Development.

This book represents a landmark effort to probe and analyze the theory and empirics of designing water disaster management policies. It consists of seven chapters that examine, in-depth and comprehensively, issues that are central to crafting effective policies for water disaster management. The authors use historical surveys, institutional analysis, econometric investigations, empirical case studies, and conceptual-theoretical discussions to clarify and illuminate the complex policy process. The specific topics studied in this book include a review and analysis of key policy areas and research priority areas associated with water disaster management, community participation in disaster risk reduction, the economics and politics of 'green' flood control, probabilistic flood forecasting for flood risk management, polycentric governance and flood risk management, drought management with the aid of dynamic inter-generational preferences, and how social resilience can inform SA/SIA for adaptive planning for climate change in vulnerable areas. A unique feature of this book is its analysis of the causes and consequences of water disasters and efforts to address them successfully through policy-rich, cross-disciplinary and transnational papers. This book is designed to help enrich the sparse discourse on water disaster management policies and galvanize water professionals to craft creative solutions to tackle water disasters efficiently, equitably, and sustainably. This book should also be of considerable use to disaster management professionals, in general, and natural resource policy analysts. This book was published as a special issue of the Journal of Natural Resource Policy Research.

Harmful algal blooms (HABs) occurring in freshwater, and the associated toxins they produce, are dangerous to animals and humans. Mitigating the increasing presence of HABs presents a major challenge to water managers and drinking water utilities across the world. This book explores the current research on removal of HABs and toxins from drinking water. It provides the necessary tools so that treatment plant operators, engineers, and water managers can understand the vulnerability of drinking water treatment plants to HABs and develop treatment processes to minimize the impact of these contaminants. Although conventional treatment processes can be effective for the removal of HAB cells and some HAB toxins under optimal conditions, the potential exists for significant breakthrough of toxins during normal operation. As a result, there is a recognized need for more advanced techniques. Possible advanced processes for removing HAB toxins include granular activated carbon (GAC), powdered activated carbon (PAC), or oxidative processes. This book reviews both conventional and advanced treatment processes and presents clear and easy-to-understand procedures for the design of systems for optimal cell or toxin removal.

First published in 1992, this title offers an experienced and constructive evaluation of the ways in which water resources have been developed in Africa. Adams argues that the best hope of productive development lies in working and engaging with local people and using local knowledge of the environment effectively. Modern, large-scale developments that have largely been ineffective are examined, and emphasis is placed on the importance of using the skills and concerns of those affected, such as small farmers, to develop ingenious water projects - an approach that can be applied worldwide. This is an interesting and relevant title, which will be of particular value to those with an interest in the developments in water resource conservation over the past two decades.
