That is why our SENTINEL packages pair a whole-home system with a PureGuard RO & PureGuard ULTRA drinking water system. The softener and AquaCarb handle the water that goes on you. Reverse osmosis handles the water that goes in you. Salt delivery and filter changes are covered by the UnitedCare Membership.

About This Report

Test results come from the Texas Commission on Environmental Quality (TCEQ) Drinking Water Viewer, covering samples collected October 2023 through October 2026. Legal limits and health goals are from the U.S. Environmental Protection Agency's National Primary and Secondary Drinking Water Regulations. "Average found" is the average of samples where the contaminant was detected.

Utility reports show the water the utility delivers. What comes out of your tap also depends on your home's plumbing. Lead and copper results come from samples taken at customers' taps. The best way to know what is in your water is to test it at your sink. We do that for free.

Every utility listed here is required to meet federal standards, and finding a contaminant above a health goal does not mean a utility is out of compliance.
