MODERN WATER PURIFICATION PLANTS are very complex, and require well trained staff to run them. Read a thorough essay on the process from source to tap, and be prepared to be surprised. Your water is not a simple process. http://lnkd.in/dxmqCmv View in LinkedIn

UBIQUITOUS CHLORINATED WATER. "Every day, approximately 170,000 (U.S. EPA, 2002) public water systems treat and convey billions of gallons of water through approximately 880,000 miles of distribution system piping to U.S. homes, farms and businesses." http://www.waterandhealth.org/drinkingwater/wp.html View in LinkedIn

CONCENTRATION OF CHLORINE IN DRINKING WATER. "Chlorine is present in drinking water at 0.2-1.0 mg/Liter. Chlorine is present in water as hypochlorous acid and hyperchlorites." http://lnkd.in/dXvsKvD View in LinkedIn

CHLORINATED WATER IS TAKEN FOR GRANTED. "According to the American Water Works Association, 98 percent of modern U.S. water treatment facilities use chlorine disinfectants to disinfect drinking water." http://lnkd.in/dJS6auR View in LinkedIn

CHORINE KILLS MICROORGANISMS. "Washing whole and cut produce by dipping or submerging in chlorinated water has a sanitizing effect, although reduction in microbial populations is minimal and is usually less than 100-fold. Chlorine was generally more effective at 2,000 ppm than at 200 ppm. Inactivation of microorganisms occurred essentially within 1 min." http://www.ingentaconnect.com/content/iafp/jfp/1998/00000061/00000010/art00008 View in LinkedIn

"CHLORINE is a highly efficient disinfectant, and is added to public water supplies to kill disease-causing pathogens ... that commonly grow in water supply reservoirs, on the walls of water mains and in storage tanks ... cholera, typhoid fever, and dysentery killed countless people annually before disinfection methods were employed routinely." http://en.wikipedia.org/wiki/Water_chlorination View in LinkedIn

POLYDADMAC AND EIPDMA are used in water pre-treatment as coagulants, and they "have been associated with the formation of nitrosamines. There are about 9 compounds in this general group that can be produced as DBP from chlorination. These compounds are toxic and may be carcinogenic." http://lnkd.in/dxmqCmv View in LinkedIn

INDUSTRY SAYS POLYDADMAC IS SAFE. But it results in "fewer disinfection byproduct precursors." Discovered in 1957, it is a very high molecular weight polymer." This is far from the full story. http://lnkd.in/ddASPkbhttp://lnkd.in/dTyfxpm View in LinkedIn

US PUBLIC WATER PRE-TREATMENTS include ... aluminum sulfate, iron sulfate, aluminium chlorohydrate, poly aluminium chloride, aluminium chlorohydrate, polyaluminium chlorosulphate, polyaluminium silicosulphate, sodium alumina the, polyferric sulphate, ferric chloride, or inorganic polymers such as PolyDADMAC ... as coagulants." http://www.wioa.org.au/conference_papers/05/paper10.htm View in LinkedIn

"PUBLIC DRINKING WATER IN THE US is treated rather differently from that in Europe, where ozone purification is most common, in contrast to chlorine, chloramine, or sodium hypochlorite treatment. Chloramine is becoming more popular in the US as it does not form carcinogenic byproducts." Not completely correct. http://lnkd.in/dTyfxpm View in LinkedIn
