Press Release ISBN Binding List Price Web Discount Price Add to Shopping Cart hardcover International Price The Safe Drinking Water Act directs the U.S. Environmental Protection Agency (EPA) to regulate the quality of drinking water, including its concentration of radon, an acknowledged carcinogen. This book presents a valuable synthesis of information about the total inhalation and ingestion risks posed by radon in public drinking water, including comprehensive reviews of data on the transfer of radon from water to indoor air and on outdoor levels of radon in the United States. It also presents a new analysis of a biokinetic model developed to determine the risks posed by ingestion of radon and reviews inhalation risks and the carcinogenesis process. The volume includes scenarios for quantifying the reduction in health risk that might be achieved by a program to reduce public exposure to radon. Risk Assessment of Radon in Drinking Water , reflecting research and analysis mandated by 1996 amendments to the Safe Drinking Water Act, provides comment on a variety of methods to reduce radon entry into homes and to reduce the concentrations of radon in indoor air and in water. The models, analysis, and reviews of literature contained in this book are intended to provide information that EPA will need to set a new maximum contaminant level, as it is required to do in 2000.

62. Giardia And Cryptosporidium In Drinking Water GIARDIA AND CRYPTOSPORIDIUM IN drinking water. What are Giardia and Cryptosporidium? Howcan drinking water become contaminated with these parasites? http://www.hc-sc.gc.ca/ehp/ehd/catalogue/general/iyh/giardia.htm

Previous GIARDIA AND CRYPTOSPORIDIUM IN DRINKING WATER What are Giardia and Cryptosporidium? Giardia and Cryptosporidium are microscopic parasites that can be found in water. Giardia causes an intestinal illness called giardiasis or "beaver fever." Cryptosporidium is responsible for a similar illness called cryptosporidiosis. How do these parasites cause illness? Both parasites produce cysts that are very resistant to harsh environmental conditions. When ingested, they germinate, reproduce, and cause illness. After feeding, the parasites form new cysts, which are then passed in the faeces. Studies with human volunteers have shown that ingestion of only a few cysts will cause illness. What are the symptoms? Diarrhoea, abdominal cramps, gas, malaise, and weight loss are the most common symptoms caused by Giardia . Vomiting, chills, headache, and fever may also occur. These symptoms usually surface six to 16 days after the initial contact and can continue as long as one month. The symptoms of cryptosporidiosis are similar; the most common include watery diarrhoea, abdominal cramps, nausea, and headaches. These symptoms occur within two to 25 days of infection and usually last one or two weeks; in some cases they stick around for up to a month.

THE MAGNESIUM WEB SITE was last updated on January 27, 2003 Are you getting enough magnesium to keep yourself well? "According to the U.S. National Academy of Sciences (1977) there have been more than 50 studies, in nine countries, that have indicated an inverse relationship between water hardness and mortality from cardiovascular disease. That is, people who drink water that is deficient in magnesium and calcium generally appear more susceptible to this disease. The U.S. National Academy of Sciences has estimated that a nation-wide initiative to add calcium and magnesium to soft water might reduce the annual cardiovascular death rate by 150,000 in the United States."

66. Improvement Of The Drinking Water Supply In The Paraguayan Chaco Article by The Federal Institute for Geosciences and Natural Resources. http://www.bgr.de/b1hydro/fachbeitraege/d199901/e_chaco.htm

Improvement of the drinking water supply for the poor population of the Paraguayan Chaco M. v. HOYER Sources of drinking water are scarce in the thinly populated Paraguayan Chaco. Most of the groundwater is saline, there are no permanent streams or lakes. Drinking water is traditionally obtained by collecting rain water from roofs and storage in cisterns, collecting surface runoff in artificial basins (tajamars) (Fig. 1), and abstraction from small, local fresh water occurrences. In the Technical Cooperation project "Exploration and Development of Groundwater Resources in the Western Part of Paraguay", the results of hydrogeological exploration are used to improve the supply of drinking water to the Indian and Campesino communities. Simple methods adapted to the local conditions are used for the water supply systems. The water is pumped using windmills (Fig. 2). The village communities are fully integrated into the planning and construction activities of the project. Much of the work is done by the local people (Fig. 3). For this reason, the population identify with the project and learn the skills and techniques needed to operate and maintain the system. Fig. 1: Tajamar

Maps, Figures, Photos Charnock MTBE Cleanup Work is underway to clean up groundwater polluted with the gasoline additive MTBE in Southern California's Charnock Sub-Basin. Responsible parties are paying over $3 million per year to provide replacement water to Santa Monica and Culver City residents. The Charnock groundwater sub-basin is located in Southern California within the communities of West Los Angeles and Culver City ( Site Location Map , 111 KB PDF) and is an important source of drinking water for the cities of Santa Monica and Culver City. The City of Santa Monica sought assistance from EPA after shutting down a number of its drinking water wells in 1996 due to the presence of increasing levels of the gasoline additive Methyl tert Butyl Ether (MTBE). Affected residents of Santa Monica and Culver City are currently receiving replacement water. The Charnock Project involves the investigation and cleanup of MTBE and other gasoline-related pollution in areas affecting water quality in the Charnock Sub-basin (see map listed in the Table of Contents below) and the restoration of this sub-basin for use as a drinking water supply.

Recent Additions Contact Us Print Version Search: EPA Home Water Sulfate in Drinking Water Drinking Water and Health Basics Frequently Asked Questions ... Security Sulfate in Drinking Water Background Sulfate is a substance that occurs naturally in drinking water. Health concerns regarding sulfate in drinking water have been raised because of reports that diarrhea may be associated with the ingestion of water containing high levels of sulfate. Of particular concern are groups within the general population that may be at greater risk from the laxative effects of sulfate when they experience an abrupt change from drinking water with low sulfate concentrations to drinking water with high sulfate concentrations. Sulfate in drinking water currently has a secondary maximum contaminant level (SMCL) of 250 milligrams per liter (mg/L), based on aesthetic effects (i.e., taste and odor). This regulation is not a Federally enforceable standard, but is provided as a guideline for States and public water systems. EPA estimates that about 3% of the public drinking water systems in the country may have sulfate levels of 250 mg/L or greater. The Safe Drinking Water Act (SDWA), as amended in 1996, directs the U.S. Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC) to jointly conduct a study to establish a reliable dose-response relationship for the adverse human health effects from exposure to sulfate in drinking water, including the health effects that may be experienced by sensitive subpopulations (infants and travelers). SDWA specifies that the study be based on the best available peer-reviewed science and supporting studies, conducted in consultation with interested States, and completed in February 1999.
