Everything You Wanted To Know About Drinking Water,
But Didn't Know Who To Ask

I developed this web site to provide a comprehensive resource for anyone searching for information about the safety and quality of their drinking water. Topics discussed include: Contaminants That Could Be In Your Drinking Water (view) (lead, chlorine, disinfection byproducts, cryptosporidia, giardia, bacteria, endocrine disrupters, pesticides, etc.) What Various Contaminants Can Do To Your Health   (with an emphasis on  children and pregnancy) What's The Best Drinking Water Purification Method For You? (view) (filtration, reverse osmosis, distillation, bottled water, KDF, emergency treatment, etc.) (Visit my new site:  Four steps to help you select a water treatment method) Drinking Water Scams (Oxygenated H20) (Other) (Beware of product claims to alter water's structure & provide greater health benefits) Headlines: Prescription drugs found in drinking water across U.S.   3/10/08 (AP) -- A vast array of pharmaceuticals -- including antibiotics, anti-convulsants, mood stabilizers and sex hormones -- have been found in the drinking water supplies of at least 41 million Americans...   To be sure, the concentrations of these pharmaceuticals are tiny, measured in quantities of parts per billion or trillion, far below the levels of a medical dose. Also, utilities insist their water is safe... Pharmaceutical Reduction Certain common pharmaceutical compounds are effectively removed by  advanced oxidation practices, i.e., ozone and ultraviolet (UV) or ozone and hydrogen peroxide. In addition, membrane filtration and filtration with granular activated carbon are thought to be highly effective. Nano-filtration and reverse osmosis eliminated all drugs tested. I have distilled the results  of many hours of research into the discussions and the lists of drinking water related sites on the pages indexed to the right.  I hope that the information here will be helpful in your search for answers to this important health issue. Although the site discusses contaminants found in water from both municipal water companies and from private wells, the treatment methods discussed, are mostly Point of Use (POU) - water is treated at the point where it will be used for drinking, cooking, etc.  Many private well water problems, bacteria, iron, heavy metals, pH imbalances, etc., need to be treated either at the well, or as the water enters the home.  I do not go into much detail about these treatment methods, but I provide references to some sites that do discuss these treatment options. The majority of web references for which I have provided links can be considered authoritative. The sites you will find listed here include: Government sites, like the Environmental Protection Agency, The National Library of Medicine, and The Centers for Disease Control and Prevention;  Environmental organizations, like the National Resource Defense Council and the Environmental Working Group;  Water industry groups and treatment facilities, like NSF International, the American Water Works Association, the Association of Metropolitan Water Agencies, and Denver Water, and the National Drinking Water Clearinghouse; University based cooperative extension services and research groups, like the North Carolina Cooperative Extension Service and the Research Division of Biology, Kansas State University;  Media publications, like Popular Science and various newspaper articles. Summary of Water Treatment Methods: Importance of Certification Purification/Disinfection Filtration General   Activated Carbon    - Solid Block (SBAC)    - Granular (GAC)   Reverse Osmosis   KDF   Sediment Bottled Water Boiling Distillation UV Disinfection Ozone Disinfection Chlorine Disinfection Ion Exchange Water Related Topics of Special Interest Special focus on lead as it relates to pregnancy and young children.       (Prompted by two questions I received in one week)     If you are are just browsing water issues and are not in the high risk category for lead poisoning     (pregnant or have a young child), but  you  know someone who is pregnant or has young children,     please suggest they read this information as soon as possible! Bottled water reports by Reader's Digest (2/08) and National Geographic (2/06)     Summary: Bottled water is no better regulated and not necessarily any safer than most tap water,     and although bottle labels often portray the source water as originating in  pure, exotic locations, over     25% of bottled water (including many top name brands) comes from municipal sources.  Bottled     water costs hundreds to thousands of times more than tap water.   Bottle manufacture and water     treatment use resources and create waste products.  Transporting the full bottles to the store uses     resources and creates waste.  An estimated 90% of the billions of water bottles produced in a year     wind up in land fills. Don't miss "Penn and Teller's "The Truth About Bottled Water".  The pair are     a bit crude, and perhaps their experiments are not as "scientific" as they could be, but some very     interesting results are demonstrated about the power of suggestion. The Placebo Effect episode     further illustrates how suggestion and an uncritical willingness to believe can explain not only     people's perceptions about bottled water but their acceptance of claims from downright fraudulent     companies. (More about bottled water) Water Lead-Levels Misrepresented - Dozens of the nation's largest drinking-water utilities     have tried to hide lead contamination and failed to correct problems, the Washington Post reported     Tuesday. The newspaper analyzed data from 65 large water systems in the United States and found     that high lead levels were concealed from regulators. (NPR, All Things Considered) Disinfiction Byproducts (DBPs) According to a study in the November {2006} issue of the     American Journal of Epidemiology, a team of researchers at the University of North Carolina School     of Public Health headed by David A. Savitz, Ph.D., Director of the Center of Excellence in     Epidemiology, Biostatistics, and Disease Prevention at MSSM, and formerly Chair of the Department     of Epidemiology at the University of North Carolina at Chapel Hill, have determined that drinking water     DBPs -- in the range commonly encountered in the US -- do not affect fetal survival. This finding is     particularly important because previous research has suggested that exposure to elevated levels of     drinking water DBPs might cause pregnancy loss.    A  Houston Chronicle series exploring the safety of the nation's  tap water and     explaining the dangers threatening our water and what communities can do to protect it.     (October 1996) The newspaper has retained the article, for which I am glad, but removed the high-level links and       index, for which I am NOT glad.  I attempted to recreate links to the original stories.    (note the common themes in this series, the 2002 articles, and the 2004 stories) U.S. News and World Report on Drinking Water (8/12/02)     The coming water crisis  Across the country, long-neglected mains and pipes, many more     than a century old, are reaching the end of their life span. When pipes fail, pressure drops and sucks     dirt, debris, and often bacteria and other pathogens into the huge underground arteries that deliver     water......     While pregnancy-risk research {on chlorine byproducts} is hotly debated, the EPA decided that     cancer risk from chlorine by-products is high enough that it ordered water system reductions earlier     this year......    Do it yourself If there's trouble at the tap  Consumers are embarking on their own efforts to     ensure safe drinking water at home. But choices about testing water, filtering it, or switching to     bottled are far from clear.......     Most bottled water is clean. But in 1999, a Natural Resources Defense Council study showed that     four of 103 tested brands of bottled water violated federal standards for chemicals or coliform     bacteria, while one quarter fell short of stricter California standards for other contaminants...... National Public Radio report on drinking water contaminants:     Weak Drinking Water Laws Blamed in D.C. Lead Scare - April 19, 2004     News of dangerous levels of lead in Washington D.C.'s drinking water sparks an outcry from the     community -- especially because city water officials knew about the problem and did little to warn     the public. In the first of two reports, NPR's Daniel Zwerdling explains that weak federal laws     regulating drinking water are to blame.     Aging Water Systems Plague Cities - April 20, 2004     Lead in drinking water in Washington, D.C., is just part of a larger, more profound problem that     affects cities across the country. In his second report about contaminated drinking water, NPR's     Daniel Zwerdling reveals that many cities are still getting their drinking water from systems that date     back to the 19th and early 20th centuries.
