The City of Arlington's tap water meets and in many cases is much better than Texas and USEPA drinking water standards that are set after robust scientific research and standard setting procedures. In 2021, our laboratory analyzed 6,131 samples for 372 different substances. The results of these tests are featured in our 2021 Consumer Confidence Report, available since May 2 at this web address: The USEPA standards are set to provide a national standard that spans the enormity of the United States with vigorously scientifically researched standards to provide consistency and enforcement.

Past Water Quality Reports

Residents who want to change the water profile with regard to taste/odor or hardness qualities should do independent research and then select the system that would address their concerns. Our laboratory experts remind residents of the importance of maintaining any system to prevent problems. The department recommends evaluating independent research. Fact sheets on various home water filter systems are available at this link.
