OFFICIALS WORKING TO IMPROVE TASTE OF WATER BEING PROVIDED TO COLLEYVILLE
While the taste of the water in Colleyville has temporarily changed, officials from the Trinity River Authority (TRA) and the Tarrant Regional Water District (TRWD) have assured the city that the water continues to be safe. The water has been tested and all test results have met or exceeded Texas Commission on Environmental Quality (TCEQ) requirements.
When a change in the taste of the water was detected, the city contacted the Trinity River Authority (TRA), our water provider. They in turn, talked to the Tarrant Regional Water District (TRWD), TRA’s water supplier, since TRWD determines the blend of raw water delivered to Lake Arlington (Colleyville’s primary source for water). TRWD uses several water sources to provide raw water, including Benbrook Lake, Richland Chambers Lake, and Cedar Creek Lake. Once the water is at Lake Arlington, TRA receives it for treatment.
Water from Benbrook Lake has a history of high levels of Geosmin, an organic compound with a distinct earthy flavor and aroma, as well as MIB (2-Methylisoborneol, another organic chemical with strong odor). Warmer water temperatures in area lakes have increased algae growth that forms MIB. Both Geosmin and MIB can affect the taste of the water.
Officials now have reduced the amount of water coming from Benbrook Lake. TRA is also analyzing samples and adjusting treatment techniques to address the taste concerns. In addition, Tarrant County Water Supply Project (TCWSP), the entity responsible for treating the raw water that comes to Colleyville, has increased the ozone feed rate and added hydrogen peroxide to reduce MIB levels. TCWSP has lowered their storage levels and is working with the city to change out the water in the city’s system. The taste of the water is expected to improve in the next few weeks.
