Like many communities in the desert southwest, Phoenix, Arizona's water supply includes wells with arsenic concentrations exceeding 10 ppb. Long before the USEPA revised the arsenic rule from 50 parts per billion (ppb) to 10, the City of Phoenix began bench and pilot scale studies for arsenic removal options. Early investigations focused on well-known processes like activated alumina and ion exchange as well as less proven concepts such as coagulation-assisted microfiltration.

A public water agency in California contacted Xylem to treat remove arsenic from a groundwater supply. They needed to achieve a 1 ppb effluent level from the treatment system, 90% lower than the current drinking water standard in California. In addition they needed to have the treatment operating within weeks.

The Water Division provides continuous high quality water to approximately 43,500 that call Moline home. It utilizes the Mississippi River as its source to treat, pump, and meter water to over 17,000 homes and businesses. The variable quality of the water in the Mississippi source poses unique treatment challenges to the Water Division. Moline’s LT2 water study revealed that significant levels of Cryptosporidium are periodically present in the source water.

The 34 MGD Otay Water Treatment Plant in San Diego, California serves a population of approx. 200,000. The plant receives raw water from two sources - imported water from the Colorado River and runoff from three local reservoirs.

Santa Clarita is located about 35 miles north of Los Angeles. The Santa Clarita Valley Water Agency (SCV Water) services nearly 74,000 customers and obtains about 50% of its drinking water through local groundwater aquifers. Positioned behind the William S. Hart community baseball and softball fields three two-vessel systems have been installed to remove PFAS from drinking water.

SES Water supplies 160 million litres of clean water daily to over 735,000 people in the UK across parts of Surrey, Kent West Sussex and South London. Westwood Water Treatment Works in Surrey is central to keeping its supply of water safe for local residents.

The source of the contaminated water was located approximately 250 meters away from the municipal well, at a former industrial site. Upon learning of the elevated test results, the state issued a “do not drink” order to the 450 residents served by the municipal water supply until the water source could pass quality testing again.
