Your water in Round Rock
The City of Round Rock’s 2025 water quality report names Lake Georgetown, the Edwards Aquifer and Lake Travis water treated by the Brushy Creek Regional Utility Authority as its sources. The disinfectant it lists is chloramine, averaging 2.15 ppm. Hardness averaged 258 ppm as calcium carbonate, across samples from 100 to 358 ppm.
EPA’s pool guidance notes that pool water builds up mineral salts over time and that the buildup has to be managed to prevent scale, so calcium hardness is on the test list at every weekly visit.
