US EPA ON INTRUSION PROBLEMS. Low or negative water pipe pressures, especially below the water table, result in up to 50% of the pipes being contaminated with fecal bacteria and viruses from outside the distribution system (a study of 8 facilities in 6 US states). http://lnkd.in/dduVeJq View in LinkedIn

NO CLEAN CHOICES. "In California, 680 community water systems are forced to rely solely upon a contaminated groundwater source. Nearly 40 percent of these water treatment systems have been in violation of standards, according to the California Department of Public Health." http://www.watertechonline.com/articles/166470-infusing-technology-into-the-drinking-water-industrys-future View in LinkedIn

US WATER QUALITY VIOLATIONS. "In 2011, there were 8,322 reported violations of maximum contaminant levels affecting 14,915,599 people. There were 109,167 total violations from all categories in 2011 — a big increase from 2010 where there were only 75,857 total violations." http://www.watertechonline.com/articles/166470-infusing-technology-into-the-drinking-water-industrys-future View in LinkedIn

FRAGMENTED WATER SYSTEMS. "There are approximately 161,000 public water systems in the U.S., including about 53,000 community water systems, the remainder are non community systems. Of those, an alarmingly high number have been found violating maximum contaminant levels or treatment standards." http://www.watertechonline.com/articles/166470-infusing-technology-into-the-drinking-water-industrys-future View in LinkedIn

INFRASTRUCTURE INVESTMENT UNPOPULAR. “For decades, these systems ... have been ignored by politicians and residents accustomed to paying almost nothing for water delivery and sewage removal. And so each year, hundreds of thousands of ruptures damage streets and homes and cause dangerous pollutants to seep into drinking water supplies.” http://realtruth.org/articles/100709-002-americas.html View in LinkedIn

CRUMBLING US WATER INFRASTRUCTURE. "According to the American Society of Civil Engineers report card, there are about 170,000 public drinking water systems and more than 1 million miles of water mains throughout the country. Some of those pipes are from the Civil War period." http://lnkd.in/dfHUZnx View in LinkedIn

"POINT-OF-USE DEVICES (such as under-the-sink activated-carbon and/or membrane filters or ultraviolet (UV)-light disinfection units) and bottled water are likely to become increasingly popular. However, bottled water and point-of-use devices in California — as currently produced, regulated and marketed — are not reliable alternatives to the available public water supply." http://lnkd.in/dssgvHd View in LinkedIn

LONDON WATER INFRASTRUCTURE. "Every day, Thames Water ... supplies 2.6 gigalitres (2.6×10(9) litres) of ... water from 102 water treatment works via 288 clean water pumping stations through 31,100 km (19,300 mi) to 9 million customers (3.6 million properties) across London ... 30 raw water reservoirs and 235 underground service reservoirs." http://lnkd.in/dPHvd8U View in LinkedIn

POOR COUNTRIES cannot afford complex water purification systems. Point-of-use UV purification has been shown to significantly reduce severe diarrheal diseases in children. In Chiapas Mexico, only 31% of water is fit for human consumption. UV kits are highly effective (99-100%) at eliminating parasites, bacteria and viruses, but in field use they were less effective. http://lnkd.in/dWFacSa View in LinkedIn

EVERY SOURCE OF WATER LEAKAGE is also a potential pathogen and unwanted pollutants entry point into previously treated water. With 19,000 miles of piping and up to 900 mega liters of leakage per day, the London Thames Water system is simply too vast a system to operate without these problems. London is not alone. New solutions are needed. View in LinkedIn
