Book Description
A memoir of family, mining pioneers and unscrupulous magnates, and the fight for Minnesota’s natural resources In 1855 the Merritt family arrived in Minnesota, where a descendant, Alfred, would one day become one of the “Seven Iron Men”—builders of the first mines to tap the state’s great mineral wealth in the Mesabi Range. Another Merritt, more than half a century later, would lead the efforts to protect Lake Superior from damage caused by mining. Iron and Water is Grant J. Merritt’s memoir of his life’s work on behalf of Minnesota’s people and environment and also the story of a significant family in state history. Merritt’s family played a key role in the struggle over natural resources in Minnesota—for the enrichment of mining pioneers, the prosperity of the state and its people, and the prospect of a secure and healthy future. This complex tale begins with the adventure of discovering iron ore and building the mines, railroads, and docks to move it, then devolves into the intrigues of business partnerships gone bad and attempts by John D. Rockefeller to defraud the Merritts. What follows is an engrossing account of Grant Merritt’s years in the halls of state politics and the trenches of environmental activism in defense of Minnesota’s North Shore and Lake Superior’s waters. The author’s tenure as head of the Minnesota Pollution Control Agency under Governor Wendell Anderson and his service on the first board of the Minnesota Environmental Quality Council take us behind the scenes of landmark legal cases and crucial moments in Minnesota history—particularly the notable Reserve Mining case, in which the company was found liable for serious environmental and health threats on the shores of Lake Superior and ordered to be shut down. In these pages we encounter the people who were critical to this history, from robber baron Rockefeller to judges, activists, and politicians, including Walter Mondale and Jim Oberstar. In chronicling both the discovery of vast iron deposits on the Mesabi Range and the fight to save Lake Superior and Minnesota’s natural riches, Iron and Water reveals how, whether alone or together, individuals wield the power to change the world.

Book Description
Nanotechnology has a great potential for providing efficient, cost-effective, and environmentally acceptable solutions to face the increasing requirements on quality and quantity of fresh water for industrial, agricultural, or human use. Iron nanomaterials, either zerovalent iron (nZVI) or iron oxides (nFeOx), present key physicochemical properties that make them particularly attractive as contaminant removal agents for water and soil cleaning. The large surface area of these nanoparticles imparts high sorption capacity to them, along with the ability to be functionalized for the enhancement of their affinity and selectivity. However, one of the most important properties is the outstanding capacity to act as redox-active materials, transforming the pollutants to less noxious chemical species by either oxidation or reduction, such as reduction of Cr(VI) to Cr(III) and dehalogenation of hydrocarbons. This book focuses on the methods of preparation of iron nanomaterials that can carry out contaminant removal processes and the use of these nanoparticles for cleaning waters and soils. It carefully explains the different aspects of the synthesis and characterization of iron nanoparticles and methods to evaluate their ability to remove contaminants, along with practical deployment. It overviews the advantages and disadvantages of using iron-based nanomaterials and presents a vision for the future of this nanotechnology. While this is an easy-to-understand book for beginners, it provides the latest updates to experts of this field. It also opens a multidisciplinary scope for engineers, scientists, and undergraduate and postgraduate students. Although there are a number of books published on the subject of nanomaterials, not too many of them are especially devoted to iron materials, which are rather of low cost, are nontoxic, and can be prepared easily and envisaged to be used in a large variety of applications. The literature has scarce reviews on preparation of iron nanoparticles from natural sources and lacks emphasis on the different processes, such as adsorption, redox pathways, and ionic exchange, taking place in the removal of different pollutants. Reports and mechanisms on soil treatment are not commonly found in the literature. This book opens a multidisciplinary scope for engineers and scientists and also for undergraduate or postgraduate students.

Book Description
This book is designed to be of use to the reader in two different ways. First, it is intended to provide a general introduction to all aspects of iron chemistry for readers from a variety of different scientific backgrounds. It has been written at a level suitable for use by graduates and advanced undergraduates in chemistry and biochemistry, and graduates in physics, geology, materials science, metallurgy and biology. It is not designed to be a dictionary of iron compounds but rather to provide each user with the necessary tools and background to pursue their ,individual interests in the wide areas that are influenced by the chemistry of iron. To achieve this goal each chapter has been written by a contemporary expert active in the subject so that the reader will benefit from their individual insight. Although it is generally assumed that the reader will have an understanding of bonding theories and general chemistry, the book is well referenced so that any deficiencies in the reader's background can be addressed. The book was also designed as a general reference book for initial pointers into a scientific literature that is growing steadily as the understanding and uses of this astonishingly versatile element continue to develop. To meet this aim the book attempts some coverage of all aspects of the chemistry of iron, not only outlining what understanding has been achieved to date but also identifying targets to be aimed at in the future.

Book Description
This Best Practice Guide on the Control of Iron and Manganese in Water Supply is one of a series produced by the International Water Association’s Specialist Group on Metals and Related Substances in Drinking Water. Iron and manganese are often found in soft upland water sources associated with natural organic matter and are also commonly found in the groundwater abstracted from confined and unconfined aquifers. The presence of iron and manganese in water is one of the most frequent reasons for customers’ complaint due to aesthetic issues (yellow, brown and black or stains on laundry and plumbing fixtures). These two metals can be removed fairly readily by physico-chemical treatment. The municipal treatment systems deployed derive benefit from their larger scale, particularly in relation to control, but the processes used are less suitable for the numerous small supplies that are the most common water supplies throughout Europe, especially in rural areas. One important source of iron in drinking water is from old corroded cast-iron water mains, historically the material used most commonly in supply networks. Replacement and refurbishment is very expensive and the major challenge is how best to prioritize available expenditure. The purpose for this Best Practice Guide on the Control of Iron and Manganese in Water Supply is to give readers the broad view of a problem based on state-of-the-art compilation of the range of scientific, engineering, regulatory and operational issues concerned with the control of iron and manganese in drinking water. The Guide is of interest to water utility practitioners, health agencies and policy makers, as well as students on civil engineering and environmental engineering courses.

Book Description
The acclaimed travel writer's youthful journey - as an 18-year-old - across 1930s Europe by foot began in A Time of Gifts, which covered the author's exacting journey from the Lowlands as far as Hungary. Picking up from the very spot on a bridge across the Danube where his readers last saw him, we travel on with him across the great Hungarian Plain on horseback, and over the Romanian border to Transylvania. The trip was an exploration of a continent which was already showing signs of the holocaust which was to come. Although frequently praised for his lyrical writing, Fermor's account also provides a coherent understanding of the dramatic events then unfolding in Middle Europe. But the delight remains in travelling with him in his picaresque journey past remote castles, mountain villages, monasteries and towering ranges.

Book Description
The principal objective of this research project was to develop a methodology that would assist water distribution engineers estimating the optimum time to replace grey cast iron water mains. The methodology should integrate information on corrosion-induced pit dimensions, effective pipe wall thickness, residual strength of grey cast iron, corrosion rates and the mechanical behavior of metallic water mains. Secondary objectives within the project were: to determine the most effective and practical approaches to measure the residual strength of grey cast iron pipe; to determine whether current or near-term nondestructive testing technology could be used to produce the necessary information on corrosion put dimensions; and to expand the current state of knowledge with respect to the mechanical behaviour of grey cast iron water mains.
