Consumer Confidence Report Water Quality Report-2016-ENG

2016 W TI R UTILIT AT ER I UTILI A r l i n g to n Wat e r U t i l i t i e s Water Quality Report TI UTILI E AT ER I AT R UTILIT E AT Your water, our responsibility Arlington Water Utilities takes pride in meeting or exceeding all federal and state guidelines. The water sent to Arlington residents, businesses and visitors is treated at the state-of-the-art Pierce-Burch and the John F. Kubala Water Treatment Plants. Ozone is used as the primary disinfectant. Aluminum sulfate and a cationic polymer are added to help dirt and other particles clump together and settle out during treatment. The water is then filtered through granular activated carbon beds to remove smaller particles and substances that are dissolved in the water. The water is treated with chloramine (chlorine and ammonia) as it enters the pipe system. Chloramine is a disinfectant that keeps the water safe on its way to your faucet. In 2015, the Arlington City Council approved an 18-month, $14 million equipment upgrade at the treatment plants. Replacing aged ozone generators and installing advanced control systems will make the plants more efficient and less costly to run. Arlington Water Utilities tests drinking water at over 120 taps all over the city each month. In 2016, the laboratory collected about 5,000 samples and performed about 22,350 tests monitoring 144 analytes. This report contains data collected from Jan. 1, 2016 through Dec. 31, 2016, unless another time frame is noted. Where does Arlington drinking water come from? Arlington gets its water for treatment from the Tarrant Regional Water District. The water comes from four reservoirs - Cedar Creek, Richland- Chambers, Lake Arlington and Lake Benbrook.
