Water Quality Information

Annual Drinking Water Quality Report

Southlake Water Utilities adheres to the highest state and federal drinking water standards. We routinely collect samples and run tests required by the EPA, and those test results are reflected in our Annual Drinking Water Quality Report each year. Take a look at the latest 2021 Annual Water Quality Report to see how we measured up this year.

February 21, 2021 Water Quality Report

The City of Southlake provided six samples to the Fort Worth Water Centralized Water and Wastewater Laboratory, exceeding the TCEQ minimum of two. The results report shows on pages 3 and 4, the absence of Coliform and Total Coliform for all six samples submitted. Page 5 of the report, shows the results of a quality control test conducted by the lab to ensure that laboratory parameters were reading results properly. The item that indicates "presence" on that page, was not a result of tests conducted on Southlake samples, but rather an internal control test conducted to ensure that the laboratory was calibrated properly to be able to detect the presence of coliform.
