Only chemicals that are approved by the National Safety Foundation for treatment of drinking water. The annual AGUA SUD Consumer Confidence Report or CCR indicates the chemicals we use.

Most, if not all, drinking water in the valley comes from the Rio Grande River and from time to time, the algae and organics impart a musty odor to the water. Sometimes the odors intensify as the chlorine used for disinfection comes in contact with these organics.

All public water systems in the state of Texas are required to maintain a minimum chlorine level of 0.5 (tested at the end of the system) by state law. We maintain a level of 2.0 through 3.0 at the source (tested at the beginning of the system). Our chlorine levels are tested daily to ensure safety. Unless you hear of a “boil water” notice from an emergency situation, your water will always be safe to drink.
