Enginering -- Civil Engineering -- CIVE448 - Drinking Water Contaminants

Arsenic contamination poses a major environmental problem, especially in Southeast Asian countries like Bangladesh and India. Threatening the health of millions of people due to arsenic's toxicity and carcinogenicity, the major routes of arsenic exposure for humans are either through drinking water or crops. Rice is the crop most affected by arsenic owing to its cultivation in major arsenic contaminated areas, biogeochemical factors in the soil during rice growth, and specific features of rice that enable it take up more arsenic than other crop plants.

Water of sufficient quality to serve as drinking water is termed potable water whether it is used as such or not. Although many sources are utilised by humans, some contain disease vectors or pathogens and cause long-term health problems if they do not meet certain water quality guidelines. Water that is not harmful for human beings is sometimes called safe water, water which is not contaminated to the extent of being unhealthy. The available supply of drinking water is an important criterion of carrying capacity, the population level that can be supported by planet Earth. Typically water supply networks deliver single or multiple qualities of water, whether it is to be used for drinking, washing or landscape irrigation; one counterexample is urban China, where drinking water can be optionally delivered by a separate tap. This book focuses on contamination, toxicity and treatment of drinking water

This new edition of The Drinking Water Handbook is thoroughly revised and updated, and includes a comprehensive discussion of the Flint, Michigan lead contamination event, new coverage of contaminants in water, such as personal care products and pharmaceuticals (PCPP) and endocrine disruptors, and examines the security requirements for waterworks and ancillary procedures.

This work provides those involved in water purification research and administration with a comprehensive resource of methods for analyzing water to assure its safety from contaminants, both natural and human caused.

Broad but reasonably detailed coverage of the environmental and health effects of the heavy P-block elements, with an emphasis on their relevant chemistry. Includes information on concentrations, sources and speciation of the heavy elements in the environment, and their effect on the health of human beings.

Excessive levels of heavy metals can be introduced into the environment, for example, by industrial waste or fertilizers. Soil represents a major sink for heavy metals ions, which can then enter the food chain via plants or leaching into groundwater. In Heavy Metal Ions in the Environment, the author looks at where heavy metals ions come from, how they interact with the environment and how they can be removed from the environment - by a process known as remediation.

In 2002, the Swedish Metal Information Task Force (MITF) engaged the Environmental Research Group (MFG) to update previous monographs on copper, zinc and major alloying metals (such as chromium, nickel and molybdenum) in society and in the environment. This book presents new results on metal fluxes from society to the environment, on metal speciation in water, soil and sediment, and its interpretation in terms of mobility, biological uptake and toxicity.

Bioremediation is an emerging field of environmental research. The objective of a bioremediation process is to immobilize contaminants (reactants) or to transform them into chemical products that do not pose a risk to human health and the environment.

Water dominates the surface of Earth and is vital to life on our planet. It is a remarkable liquid which shows anomalous behaviour. In this book, John Finney introduces the science of water, and explores how the structure of water molecules gives rise to its physical and chemical properties. Considering water in all three of its states as ice and steam as well as liquid, Finney explains the great importance of an understanding of it's structure and behaviour to a range of fields including chemistry, astrophysics, and earth and environmental sciences.
