(PhysOrg.com) -- Drinking water can transmit a number of diseases, including typhoid, dysentery, cholera, and diarrhea, which can then spread explosively throughout an entire service area. To avoid this problem, drinking water must be disinfected. After treatment and disinfection, the water is usually safe. http://www.physorg.com/news180767147.html Chemistry Wed, 23 Dec 2009 05:06:57 EST news180767147 (AP) -- Federal regulators under President Barack Obama have sharply shifted course on long-standing policy toward pharmaceutical residues in the nation's drinking water, taking a critical first step toward regulating some of the contaminants while acknowledging they could threaten human health. http://www.physorg.com/news180713428.html Space & Earth Tue, 22 Dec 2009 14:20:03 EST news180713428 India's giant Tata Group on Monday unveiled a new low-cost water purifier, hoping to do for health what it did for motoring and provide affordable, safe drinking water for millions and cut disease. http://www.physorg.com/news179390123.html Technology Mon, 07 Dec 2009 06:36:53 EST news179390123 Researchers Researchers at the Swedish medical university Karolinska Institutet have discovered a mechanism that controls the brain's ability to create lasting memories. In experiments on genetically manipulated mice, they were able to switch on and off the animals' ability to form lasting memories by adding a substance to their drinking water. The findings, which are published in the scientific journal PNAS, are of potential significance to the future treatment of Alzheimer's and stroke. http://www.physorg.com/news177089678.html Medicine & Health Tue, 10 Nov 2009 15:35:20 EST news177089678 (PhysOrg.com) -- It was the "yuck factor" of reclaimed water that got Karyna Rosario thinking. As communities increasingly turn to reclaimed water as a source for irrigation - and some communities consider using it for drinking water - Rosario, a PhD student at USF`s College of Marine Science, became increasingly curious about exactly what viruses are present in reclaimed water. http://www.physorg.com/news173351209.html Biology Mon, 28 Sep 2009 10:20:01 EST news173351209 (AP) -- Over the last decade, the drinking water at thousands of schools across the country has been found to contain unsafe levels of lead, pesticides and dozens of other toxins. http://www.physorg.com/news173077186.html Space & Earth Fri, 25 Sep 2009 06:00:23 EST news173077186 Exposure to tetrachloroethylene (also known as perchlorethylene, PCE) may cause congenital birth defects. A study of expectant women exposed to PCE in drinking water, published in BioMed Central's open access journal Environmental Health, found an increased risk of oral clefts and neural tube defects in their children. http://www.physorg.com/news172953232.html Medicine & Health Wed, 23 Sep 2009 19:35:06 EST news172953232 Climate change is shrinking three of the nation's most studied glaciers at an accelerated rate, and government scientists say that finding bolsters global concerns about rising sea levels and the availability of fresh drinking water. http://www.physorg.com/news168849624.html Space & Earth Fri, 07 Aug 2009 08:20:13 EST news168849624 The stomach ulcer bacterium Helicobacter pylori is not transmitted through drinking water as previously thought, but rather through vomit and possibly faeces. This is shown in a thesis at the Sahlgrenska Academy, University of Gothenburg, Sweden. It is therefore possible to prevent the spread of the bacterium in developing countries through some fairly simple measures. http://www.physorg.com/news165066763.html Medicine & Health Wed, 24 Jun 2009 12:53:35 EST news165066763 Rice University researchers today announced that the first field tests of "nanorust," the university's revolutionary, low-cost technology for removing arsenic from drinking water, will begin later this year in Guanajuato, Mexico. http://www.physorg.com/news162642319.html Nanotechnology Wed, 27 May 2009 11:26:02 EST news162642319 The ability to mount an immune response to influenza A (H1N1) infection is significantly compromised by a low level of arsenic exposure that commonly occurs through drinking contaminated well water, scientists at the Marine Biological Laboratory (MBL) and Dartmouth Medical School have found. http://www.physorg.com/news162048605.html Medicine & Health Wed, 20 May 2009 14:33:54 EST news162048605 Although perhaps the greatest public health achievement of the 20th century was the disinfection of water, a recent study now shows that the chemicals used to purify the water we drink and use in swimming pools react with organic material in the water yielding toxic consequences. http://www.physorg.com/news157717913.html Space & Earth Tue, 31 Mar 2009 11:32:24 EST news157717913 Both cancer cells and the chemicals used to make bombs can foil detection because they appear in trace amounts too small for conventional detection techniques. Tel Aviv University has developed the ultimate solution: a molecule that can magnify weak traces of "hidden" molecules into something we can detect and see. http://www.physorg.com/news157645544.html Chemistry Mon, 30 Mar 2009 15:26:36 EST news157645544 The device looks deceptively simple - a porous clay pot placed in a five-gallon plastic bucket with a spigot - but Vinka Craver believes it can save millions of lives each year. http://www.physorg.com/news156436938.html Technology Mon, 16 Mar 2009 15:43:37 EST news156436938 When mice are exposed to arsenic at federally-approved levels for drinking water, pores in liver blood vessels close, potentially leading to cardiovascular disease, say University of Pittsburgh researchers in the Dec. 1 issue of the Journal of Clinical Investigation, available online Nov. 13. The study, while preliminary, also reveals how an enzyme linked to hypertension and atherosclerosis alters cells, and may call into question current Environmental Protection Agency standards that are based solely on risks for cancer. http://www.physorg.com/news145818421.html Medicine & Health Thu, 13 Nov 2008 17:07:01 EST news145818421 An anticipated increased incidence of climate-related extreme rainfall events in the Great Lakes region may raise the public health risk for the 40 million people who depend on the lakes for their drinking water, according to a new study. http://www.physorg.com/news142703663.html Medicine & Health Wed, 08 Oct 2008 16:54:23 EST news142703663 Microbiologically contaminated water plagues approximately 1.1 billion people in rural and peri-urban populations in developing countries. Roughly 2.2 million people without safe access to drinking water die each year from the consumption of unsafe water, and most of them are children under 5 years of age. http://www.physorg.com/news141486132.html Biology Wed, 24 Sep 2008 14:42:12 EST news141486132 Nanotechnology could be the answer to ensuring a safe supply of drinking water for regions of the world stricken by periodic drought or where water contamination is rife.
