EPA IN BIOFILM CONTROL, and the considerable challenges of this old problem. http://lnkd.in/dnZinXQ View in LinkedIn

BIOFILMS IN WATER PIPES. "Biofilms were found to comprise a complex mixture of microorganisms, viz. fungi, yeasts, protozoa (Bodo sp.), free amoebae (Hartmannela, Vannella, Cochliopodium and Naegleria), and bacteria (up to 10(6) cells.cm−2), 19% of which were actively respiring." http://www.tandfonline.com/doi/abs/10.1080/08927019309386235 View in LinkedIn

FUNGI IN BIOFILMS IN WATER PIPES. "Uncertain ramifications of fungi in potable water have led to a limited number of investigations which show that fungi are present in a significant proportion of tap water samples; however, species abundance and diversity are extremely variable." http://lnkd.in/d6x-a3X View in LinkedIn

QUORUM SENSING IN BIOFILMS. "Quorum sensing is a system of stimulus and response correlated to population density. Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population. Quorum sensing can function as a decision-making process in any decentralized system." http://en.m.wikipedia.org/wiki/Quorum_sensing View in LinkedIn

WHY ARE CONSUMERS BUYING BOTTLED WATER? Bottled water is virtually unregulated and has no assurances of quality. If ever there was an indicator of the enormous public distrust of municipal water, it is this strong trend. http://lnkd.in/dDkmndD View in LinkedIn

BOTTLED WATER. "A report by Food And Water Watch says that almost half of all bottled water is derived from tap water. 47.8% (in 2009), to be exact. A 2009 Gallup poll said that 84% of people worry a “great deal” or a “fair amount’ about polluted drinking water." And tap water is barely regulated. http://lnkd.in/dvmGAsD View in LinkedIn

$100 BILLION PER YEAR INDUSTRY. "The U.S. drank 9 billion gallons of bottled water in 2008, at an average of 30 gallons per person. The production of water bottles uses 17 million barrels of oil a year, and it takes three times the water to make the bottle as it does to fill it." http://lnkd.in/dvmGAsD View in LinkedIn

WATER SHOCKER. "The commoditization of water has partially happened. "Designer" or bottled water is already more expensive than oil." http://www.financialpost.com/scripts/story.html?id=4b015243-8ded-409f-bddc-d1cb8924a0ff View in LinkedIn

NRDC STUDY OF BOTTLED WATER. "About 22 percent of the brands we tested contained, in at least one sample, chemical contaminants at levels above strict state health limits. If consumed over a long period of time, some of these contaminants could cause cancer or other health problems." http://lnkd.in/dphTWNT View in LinkedIn

PLASTICS LEACHING IN BOTTLED WATER: "phthalates, which are known to disrupt testosterone and other hormones ... there are no legal limits for phthalates in bottled water -- the bottled water industry waged a successful campaign opposing the FDA proposal to set a legal limit for these chemicals." http://lnkd.in/dphTWNT View in LinkedIn
