Drinking Water In Brief FAQ Arsenic in Drinking Water What are the possible health effects of arsenic in drinking water? Does it occur often? How can I find out whether my drinking water contains arsenic? How can I interpret the consequences of the level of arsenic in my drinking water? ... I drink bottled water do I have to worry about arsenic? 1. What are the possible health effects of arsenic in drinking water? According to a 1999 study by the National Academy of Sciences, arsenic in drinking water causes bladder, lung and skin cancer, and may cause kidney and liver cancer. The study also found that arsenic harms the central and peripheral nervous systems, as well as heart and blood vessels, and causes serious skin problems. It also may cause birth defects and reproductive problems. 2. Does it occur often? NRDC analyzed data compiled by the U.S. Environmental Protection Agency on arsenic in drinking water in 25 states. Our most conservative estimates based on the data indicate that more than 34 million Americans drink tap water supplied by systems containing average levels of arsenic that pose unacceptable cancer risks. We consider it likely that as many as 56 million people in those 25 states have been drinking water with arsenic at unsafe levels and that's just the 25 states that reported arsenic information to the EPA. 3. How can I find out whether my drinking water contains arsenic?

EPA recommends secondary standards to water systems but does not require systems to comply. However, states may choose to adopt them as enforceable standards.

Whether it's the stream that meanders through town, the lake where we fish and swim, the majestic ocean beaches that inspire our awe of nature, or simply the glass of water we drink, clean water is essential to our well-being. NRDC fights to safeguard drinking water, to protect, preserve and restore our rivers, streams, lakes, wetlands and coastal waters, and to promote conservation and better water management in the arid western states. Clean Water at Risk Does the Bush administration care about clean water? White House moves to lift wetlands, streams protections Clean Water Laws Under Fire: Report TV ad Act now! Wetlands at Risk: Imperiled Treasures America's wetlands, which provide critical wildlife habitat and reduce pollution and flooding, are drained, filled and polluted at an alarming rate. This July 2002 report from NRDC and the National Wildlife Federation looks at the potentially damaging consequences of a January 2001 Supreme Court decision regarding "isolated wetlands" and illustrates the vital role these areas play in ecosystems across the United States.

MCL Update Until an MCL is in place, DHS uses a 4-microgram per liter (µg/L) advisory action level to protect consumers from perchlorate's adverse health effects. Monitoring Update Click here for the monitoring update Drinking Water Vulnerability to Perchlorate California's early findings (1997) showed perchlorate to be a drinking water contaminant. Since then, 20 states have confirmed perchlorate releases in ground or surface water. Disposal of large volumes of perchlorate has occurred since the 1950s (US EPA, 2002). Recognizing facilities, processes or products that use or contain perchlorate can be helpful in identifying activities that may affect drinking water supplies. According to US EPA (2002), perchlorate (an oxidizing anion that originates from the dissolution of ammonium, potassium, magnesium, or sodium salts) is exceedingly mobile in aqueous systems, persisting for many decades under conditions typical for ground and surface water. Ammonium perchlorate is the primary ingredient in solid propellant for rockets, missiles, and fireworks. Perchlorate salts are used on a large scale as a component of air bag inflators, and also in nuclear reactors and electronic tubes, as additives in lubricating oils, in tanning and finishing leather, as a mordant for fabrics and dyes, in electroplating, in aluminum refining, and in rubber manufacture, and in the production of paints and enamels. Chemical fertilizer has been reported as a potential source of perchlorate contamination, but US EPA, based on new investigations, does not consider it to be an issue for agricultural applications (US EPA, 2002).

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 (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? (filtration, reverse osmosis, distillation, bottled water, KDF, etc.) Terrorism and Drinking Water (everything I have been able to find about the subject on the web) 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:
