Water Quality

Yes, absolutely. BPUB's water meets all federal Safe Drinking Water Act standards and TCEQ requirements. We conduct thousands of tests every year, and results consistently show our water is safe for drinking, cooking, and all household uses.

Our latest Consumer Confidence Report provides detailed test results and compliance information.

Chlorine is added to water as a disinfectant to kill harmful bacteria and viruses. The taste and odor of chlorine indicates proper disinfection is occurring. TCEQ requires water systems to maintain a chlorine residual throughout the distribution system.

If the chlorine taste is bothersome:

• Refrigerate water in an open container for a few hours to allow chlorine to dissipate
• Use a pitcher-style water filter certified to reduce chlorine taste and odor
• Run cold water for a few seconds before use

Yellow or brown water discoloration can be caused by several factors:

• Manganese: A naturally occurring mineral in groundwater that causes yellow tint
• Sediment disturbance: Hydrant flushing, water main work, or system disturbances
• Internal plumbing: Rust from galvanized pipes in older homes

While usually not a health concern, discolored water should be reported. Learn more on our Yellow Water information page.

BPUB conducts continuous water quality monitoring:

• Daily: Automated testing at treatment plants (24/7)
• Weekly: Bacteria testing throughout the distribution system
• Monthly: Comprehensive sampling at dozens of locations
• Annually: Lead and copper testing at customer taps
• Tri-annually: Additional specialized contaminant testing

All testing follows EPA and TCEQ requirements, and results are reported to regulators.

BPUB's water supply comes from two primary sources:

1. Rio Grande River - Surface water treated at our water treatment facilities
2. Groundwater Wells - Deep aquifer wells providing supplemental supply

Both sources are treated to meet drinking water standards before distribution. Learn more about our Water Strategy.

BPUB's laboratory focuses on testing for regulatory compliance at the water main and distribution system. For concerns about water quality entering your home, we can:

• Dispatch a Water Quality Specialist to investigate
• Collect samples if needed
• Provide guidance on resolving issues

For testing of internal plumbing or private wells, you may need to contact a private certified laboratory. Contact us at (956) 983-6300 for guidance.

In the rare event of a boil water notice:

1. Boil water vigorously for at least one minute before use
2. Use boiled or bottled water for drinking, cooking, ice, brushing teeth, and washing dishes
3. Follow instructions provided by BPUB (via media, website, phone alerts)
4. Wait for official "all clear" notification before resuming normal use

BPUB will notify affected customers through multiple channels and provide regular updates until the notice is lifted.
