This book was released on 2009-09-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1980s, two water-supply systems on the Marine Corps Base Camp Lejeune in North Carolina were found to be contaminated with the industrial solvents trichloroethylene (TCE) and perchloroethylene (PCE). The water systems were supplied by the Tarawa Terrace and Hadnot Point watertreatment plants, which served enlisted-family housing, barracks for unmarried service personnel, base administrative offices, schools, and recreational areas. The Hadnot Point water system also served the base hospital and an industrial area and supplied water to housing on the Holcomb Boulevard water system (full-time until 1972 and periodically thereafter). This book examines what is known about the contamination of the water supplies at Camp Lejeune and whether the contamination can be linked to any adverse health outcomes in former residents and workers at the base.

Part II: Mixtures explores the issues surrounding multiple-chemical exposure from drinking water and reviews options for grouping compounds so their toxicity in mixtures can be reliably assessed. The book describes alternative approaches and considers the option of developing a modified "hazard index" for chemical compounds.

Download or read book Drinking Water Health Advisory written by Jennifer Orme-Zavaleta and published by CRC Press. This book was released on 1990-11-16 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Health Advisories (HAs) are prepared by the Criteria and Standards Division, Office of Drinking Water (ODW) of the United States Environmental Protection Agency (USEPA) in Washington, D.C. Documents summarized in this volume are part of the Health Advisory Program sponsored by ODW in response to the public need for guidance during emergency situations involving drinking water contamination. They provide technical guidance to public health officials on health effects, analytical methodologies, and treatment technologies associated with drinking water contamination. The HAs for 15 unregulated volatile organic chemicals were developed jointly by the Environmental Criteria and Assessment Office and ODW. Each HA contains information regarding the nature of adverse health effects associated with the contaminant and contaminant concentrations that would not be anticipated to cause an adverse effect following various periods of exposure. In addition, the HA summarizes information on occurrence, analytical methods, environmental fate, and treatment techniques for the contaminant.

Download or read book Drinking Water Distribution Systems written by National Research Council and published by National Academies Press. This book was released on 2007-01-22 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

This book was released on 2005 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concentrations of 54 volatile organic compounds (VOCs) were measured in İzmir drinking water, and associated health risks due to ingestion of these compounds were investigated using a semi-probabilistic sampling design. 100 houses were visited in different districts of İzmir and drinking water samples were collected from consumer taps and bottled waters. Using questionnaires, demographics and drinking water consumption rates were determined. Individual and population based exposures and risks were estimated by employing deterministic and probabilistic approaches, respectively.Trihalomethanes (THMs) (i.e., chloroform, bromodichloromethane, dibromochloromethane, and bromoform), benzene, toluene, p-xylene, and naphthalene were the most frequently detected VOCs in İzmir drinking water with concentrations ranging from below detection limit to 35 .g/l. None of the samples exceeded the maximum contaminant levels stated in the Turkish, European, and American drinking water regulations. For all VOCs, the concentrations measured in metropolitan area were greater than those in other districts. All THM species were detected in higher concentrations in tap water.Noncarcinogenic risks attributable to ingestion of VOCs in İzmir drinking water were negligible whereas the mean carcinogenic risk estimates for bromodichloromethane and dibromochloromethane were above the acceptable level of one in a million (10-6). Deterministic approach revealed that 23%, 29%, and 2% of individuals had lifetime cancer risks greater than 10-6 associated with ingestion of bromodichloromethane, dibromochloromethane, and bromoform, respectively. The results of this study show that exposures to drinking water contaminants and associated risks may be higher than the acceptable level even if the concentrations fall below the drinking water standards.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.
