Image title	Freer Water Control and Improvement District Manager Diana Adame checks the status of the Arsenic Removal System media tanks by using a graphical computer interface in the operations office, on Tuesday June 18, 2013, in Freer Texas. The city and water district benefits from the financial assistance of the U.S. Department of Agriculture (USDA) Rural Development (RD) to complete a two-phase approach to meeting the city’s water supply and safety needs, on Tuesday, June 18, 2013. Although, the naturally occurring arsenic levels have remained constant for more than a century, the safe level standards have established lower levels of arsenic to be safe for human consumption. To meet those levels the City of Freer approached USDA and was awarded a $986,000 loan for Phase I, to install two new water wells, each rated at 167 gallons per minute; 13,600 feet of well collection lines; and 15,000 linear feet of well control line to remotely control the input of water into a reservoir holding-tank at the new ArsenicRemoval System (Phase II). Previously, water was manually controlled by personnel who knew when and how long to manually opened and closed water valves or started well pumps to ensure reservoir tank levels were within operating levels during peek and slack times of the day. Phase II was a combination of a $1,832,000 loan and a $1,258,750 grant, which provided for the customized arsenic removal system, seen in these photos. The system includes a new 3,530 sp. ft. facility, on a .76-acre site, and houses the operations room, computer and power system, laboratory room, and pump systems. The entire operation can be monitored through a desktop computer interface system. The pump system, which works in sequence, maintains a constant pressure to the system. The computer-controlled system ensures remote pumps keep holding tanks filled to the proper level, then the water is pumped through (blue) filtration media tanks to separate arsenic from the water, and then to a water reservoir tank that feeds the residential and commercial needs of the city. Samples of water are periodically tested; and so far the arsenic levels have been below 1 part per billion, well under dangerous levels. USDA Photo by Lance Cheung.
