Book excerpt: The development of analytical methods for identifying widespread perchlorate contamination brought about an explosion of research into the environmental problems and their potential solutions along with a corresponding increase in the availability of information. Unlike reference works that focus on only a few aspects of this contaminant, Perchlorate: Environmental Problems and Solutions offers a comprehensive, single source of information on perchlorate contamination in the environment. Summarizing the state of the science and developments in engineering, the book describes: Common sources of perchlorate Its behavior in the environment Methods for analyzing perchlorate in environmental samples Potential risks to human health and the environment Regulatory standards and criteria Techniques for remediating environmental contamination The authors illustrate these points with case studies of perchlorate contamination in soil, groundwater, and surface water. These case studies provide perspective on issues commonly faced by scientists, engineers, and managers of perchlorate-impacted sites. Organized to follow the logical sequence of identifying and solving contamination problems, the book provides the foundation necessary to understand perchlorate's occurrence, environmental behavior, regulatory status, and remediation.

Available in PDF, EPUB and Kindle. Book excerpt: Low concennations (microgram/L of the perchlorate anion ClO4 have been measured in drinking water supplies in many states throughout the United States. Federal and state regulatory agencies are concerned about the possible adverse effects of perchlorate contamination as the anion is known to target the human thyroid gland and its metabolic-hormone-producing function. The provisional aenon level for drinking water established by the EPA and adopted by several states is 18 microgram/L (18 ppb) perchlorate; however other states have set levels as low as 1-4 microgram/L. The major sources of perchlorate contamination in surface and ground waters are propellant manufacturers, military installations defense connactors and agriculture.

Book excerpt: This is a print on demand edition of a hard to find publication. Perchlorate is both a man-made and naturally occurring chemical used in rocket fuel, explosives, fireworks, and other products. Naturally occurring perchlorate is produced through atmospheric processes and then settles on surface water or land. It can disrupt the uptake of iodide in the thyroid, potentially interfering with thyroid function and negatively affecting fetal and infant brain development and growth. This report examined: (1) what is known about the extent to which perchlorate occurs in the nation's water and food supply and its likely sources; (2) what actions DoD, NASA, and DoE have taken to respond to or lessen perchlorate releases; and (3) what actions states, such as CA and MA, have taken to regulate perchlorate.

Available in PDF, EPUB and Kindle. Book excerpt: Perchlorate is the explosive component of solid rocket fuel, fireworks, road flares, and other products. Used heavily by the Department of Defense (DOD) and related industries, perchlorate also occurs naturally and is present in some organic fertiliser. This soluble, persistent compound has been detected in drinking water supplies, milk and many foods. Because of this widespread occurrence, concern over the potential health risks of perchlorate exposure has increased, Members of Congress have urged the Environmental Protection Agency (EPA) to set a federal drinking water standard for this chemical. This book reviews perchlorate contamination issues and related developments.

This book was released on 2005-05-18 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perchlorateâ€"a powerful oxidant used in solid rocket fuels by the military and aerospace industryâ€"has been detected in public drinking water supplies of over 11 million people at concentrations of at least 4 parts per billion (ppb). High doses of perchlorate can decrease thyroid hormone production by inhibiting the uptake of iodide by the thyroid. Thyroid hormones are critical for normal growth and development of the central nervous system of fetuses and infants. This report evaluates the potential health effects of perchlorate and the scientific underpinnings of the 2002 draft risk assessment issued by the U.S. Environmental Protection Agency (EPA). The report finds that the body can compensate for iodide deficiency, and that iodide uptake would likely have to be reduced by at least 75% for months or longer for adverse health effects, such as hypothryroidism, to occur. The report recommends using clinical studies of iodide uptake in humans as the basis for determining a reference dose rather than using studies of adverse health effects in rats that serve as EPA's basis. The report suggests that daily ingestion of 0.0007 milligrams of perchlorate per kilograms of body weightâ€"an amount more than 20 times the reference dose proposed by EPAâ€"should not threaten the health of even the most sensitive populations.

Download or read book Perchlorate written by Brian Scott Aikin and published by Lawyers & Judges Publishing. This book was released on 2006-01 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perchlorate, a naturally occurring and synthesized chemical, is generating intense publicity, scientific debate, regulatory scrutiny, and litigation across the United States. The substance has been widely used for over sixty years in the production of rocket fuel, flares, fireworks, electronics, and munitions, but did not emerge as a significant environmental issue until the mid-1990s, when improved analytical testing methods permitted its detection in groundwater at 4 parts per billion. As of 2005, perchlorate has been detected in forty-nine of the fifty states, and is the focus of mounting regulatory enforcement actions and widespread civil litigation. Perchlorate: A Scientific, Legal, and Economic Assessment is designed to educate and inform business, environmental, legal, and academic audiences about the history and development of the perchlorate controversy. It is also intended to provide practical advice and guidance to those involved in perchlorate litigation, remediation, and regulation. The book identifies and discusses existing and anticipated liability theories and damage claims asserted in perchlorate litigation. The authors explain the theories of environmental liability, identify the tort claims most commonly asserted in environmental litigation, and provide an overview of environmental class actions. The book includes chapters covering key practical issues raised in perchlorate litigation, such as estimating monetary damages, the retention and use of experts, and obtaining insurance coverage for liabilities. These important topics will assist legal and other professionals involved in current perchlorate litigation and provide a broad base of knowledge to apply in future environmental contamination litigation.
