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.
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of semi-volatile organic compounds that are formed during the incomplete burning of gas, coal, oil, wood, garbage, or other organic substances. PAHs are a concern because a number of them have been identified as genotoxic and/or carcinogenic. They pose a threat to ecological systems and can cause health problems. A significant source of PAHs is the effluent of wastewater treatment plants. This book explores the occurrence and the treatability of PAHs in wastewater treatment.

"The world water problems are a due to bad governance, not to physical water scarcity." This book is inspired by this statement and explores whether it holds in a specific country, Spain, where climatic conditions - Spain is one of the most arid countries of the European Union - would fully justify saying that water problems are due to physical water scarcity. The metrification of water uses and their monetary value is a first important step in understanding how reallocation of water among users could help mitigating many of current water problems in Spain. However, water reallocation among users or from users to nature is far from simple. Initiatives portrayed as the solution to the water governance 'jigsaw' - e.g. water trade, improved water use efficiency, users collective action, public participation - are not free of difficulties and shortcomings. The book explores the growing need for maintaining Spain's natural capital and the human component of water governance - people's needs, wishes, (vested) interests, aspirations - that often determine the result of decisions and, sometimes, lead water management to a deadlock. This book takes a step forward in showing a more complex - and also closer to reality - picture of water governance in Spain.
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.

The enhanced biological removal of phosphorus (EBPR) is a popular process due to high removal efficiency, low operational costs, and the possibility of phosphorus recovery. Nevertheless, the stability of the EBPR depends on different factors such as: temperature, pH, and the presence of toxic compounds. While extensive studies have researched the effects of temperature and pH on EBPR systems, little is known about the effects of different toxic compounds on EBPR. For example, sulphide has shown to inhibit different microbial activities in the WWTP, but the knowledge about its effects on EBPR is limited. Whereas the sulphide generated in the sewage can cause a shock effect on EBPR, the continuously exposure to sulphide potentially generated in WWTP can cause the acclimatization and adaptation of the biomass. This research suggests that sulphate reducing bacteria can proliferate in WWTP, as they are reversibly inhibited by the recirculation of sludge through anaerobic-anoxic-oxic conditions. The research enhances the understanding of the effect of sulphide on the anaerobic-oxic metabolism of PAO. It suggests that the filamentous bacteria Thiothrix caldifontis could play an important role in the biological removal of phosphorus. It questions the ability of PAO to generate energy from nitrate respiration and its use for the anoxic phosphorus uptake. Thus, the results obtained in this research can be used to understand the stability of the EBPR process under anaerobic-anoxic-oxic conditions, especially when exposed to the presence of sulphide.
This book presents research on a kind of water use conflicts that is becoming more and more common and important: How to best manage moving water in times of increasing demand for electricity as well as environmental services. How should decisions be made between water use for electricity generation or for environmental and recreational benefits? The authors develop a simple general equilibrium model of a small open economy which is used to derive a cost-benefit rule that can be used to assess projects that divert water from electricity generation to recreational and other uses (or vice versa). The cost-benefit rule is then applied to the specific case of a proposed change at a Swedish hydropower plant. The book provides a manual for the evaluation of river regulations which can easily be replicated in other studies.
Incentives in Water Quality Management explores the role of effluent charges in France and the Ruhr area of the federal republic of Germany by delving into both regulatory and economic systems that are utilised in the water quality management of these two areas. Originally published in 1981, these studies place an emphasis on the necessity of legislation in effective water quality management whilst attempting to create a complete picture of the water quality management systems in place in France and the Ruhr area. This title will be of interest to students of Environmental Studies.
As water demand has increased globally and resources have become more limited because of physical scarcity, over-exploitation and pollution, it has been necessary to develop more options for water supplies. These options include the production at large scale of high-quality reused water from municipal sources for potable uses. Their economic, social and environmental benefits have been many as they have addressed supply scarcity, efficient resource use and environmental and public health considerations. This book includes discussions on potable water reuse history; emerging contaminants and public health; public-private partnerships in the water reuse sector; regulatory frameworks for reused water in the United States and Europe; experiences in Australia, China in general and Beijing in particular, Singapore and Windhoek; narratives and public acceptance and perceptions of alternative water sources. The main constraints on implementation of water reuse projects in different parts of the world seem to have been lack of full public support due to perceived health hazards and environmental impacts. A main handicap has been that governments and water utilities have been slow to understand public concerns and perceptions. After several backlashes, public information, communication and awareness campaigns, broader participation and educational programmes have become integral parts of development policy and decision-making frameworks.
This book reviews the sources of soil and groundwater contamination and the potential remediation technologies. It focuses on remediation technologies that are commonly utilized in practice, and discusses a number of innovative technologies that show promise for special problem circumstances.
In The Netherlands, Belgium and other European countries, manganese is removed by conventional groundwater treatment with aeration and rapid (sand) filtration. Such a treatment process is easy to operate, cost effective and sustainable, because it does not make use of strong oxidants such as O3, Cl2, ClO2 and KMnO4 with the associated risk of by-product formation and over or under dosing. However, application of aeration-filtration is also facing drawbacks, especially the long ripening time of filter media. Due to the long ripening time, water companies have to waste large volumes of treated water, making this process less sustainable. Also, costs associated with filter media ripening (man power, electricity, operational and analysis costs) are high. Therefore decreasing the filter ripening time, regarding manganese removal is a big issue. Although already extended research has been carried out into manganese removal, the controlling mechanisms, especially of the start up face of filter media ripening, are not fully understood yet. The emphasis of this thesis is to provide a better understanding of the mechanisms involved in the ripening of virgin filter media, regarding manganese removal and how to shorten or completely eliminate the long ripening period of filters with virgin material. This thesis therefore highlights the role of the formation of a manganese oxide coating on virgin filter media. Characterization and identification revealed that the responsible manganese oxide for an effective manganese removal was Birnessite. It was found that Birnessite, formed at the beginning of the ripening process was of a biological origin. Based on the knowledge that manganese removal in conventional groundwater treatment is initiated biologically, long ripening times may be reduced by creating conditions favouring the growth of manganese oxidizing bacteria, e.g., by limiting the back wash frequency and / or intensity. Additionally, this thesis also shows that the use of freshly prepared manganese oxide, containing Birnessite, can completely eliminate filter media ripening time.

Selenium (Se) and tellurium (Te) are metalloids of commercial interest due to their physicochemical properties. The water soluble oxyanions of these elements (selenite, selenate, tellurite and tellurate) exhibit high toxicities; hence, their release in the environment is of great concern. This study demonstrates the potential use of fungi as Se- and Te-reducing organisms. The response of Phanerochaete chrysosporium to the presence of selenite and tellurite was evaluated, as well as its potential application in wastewater treatment and production of nanoparticles. Growth stress and morphological changes were induced in P. chrysosoporium when exposed to selenite and tellurite. Synthesis of Se0 and Te0 nanoparticles entrapped in the fungal biomass was observed, as well as the formation of unique Se0-Te0 nanocomposites when the fungus was cultivated concurrently with Se and Te. The response of P. chrysosporium to selenite exposure was investigated in different modes of fungal growth (pellets and biofilm). A bioprocess for selenite removal and Se0 nanoparticles recovery using an up-flow fungal pelleted reactor was developed. 70% selenite removal (10 mg Se L-1 d-1) was achieved under continuous mode. The use of Se0 nanoparticles immobilized in P. chrysosporium pellets as a new sorbent material for the removal of heavy metals from wastewater was demonstrated.
Reservoir operation is a multi-objective optimization problem, and is traditionally solved with dynamic programming (DP) and stochastic dynamic programming (SDP) algorithms. The thesis presents novel algorithms for optimal reservoir operation, named nested DP (nDP), nested SDP (nSDP), nested reinforcement learning (nRL) and their multi-objective (MO) variants, correspondingly MOnDP, MOnSDP and MOnRL. The idea is to include a nested optimization algorithm into each state transition, which reduces the initial problem dimension and alleviates the curse of dimensionality. These algorithms can solve multi-objective optimization problems, without significantly increasing the algorithm complexity or the computational expenses. It can additionally handle dense and irregular variable discretization. All algorithms are coded in Java and were tested on the case study of the Knezevo reservoir in the Republic of Macedonia. Nested optimization algorithms are embedded in a cloud application platform for water resources modeling and optimization. The platform is available 24/7, accessible from everywhere, scalable, distributed, interoperable, and it creates a real-time multiuser collaboration platform. This thesis contributes with new and more powerful algorithms for an optimal reservoir operation and cloud application platform. All source codes are available for public use and can be used by researchers and practitioners to further advance the mentioned areas.
In this book, first published in 1965, the authors identify the technological opportunities and costs of water recirculation and water quality adjustment in thermal plants, relating them to the possibilities for minimal expenditure and maximum efficiency in the use of water for servicing an entire region with thermal power. Water Demand for Steam Electric Generation will be of interest to students of environmental studies.
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. |
