The city of Corpus Christi is advising residents that an unusual earthy or musty taste and odor that affected tap water earlier this week is improving, though some homes may continue to notice the change as water already in the system works through the pipes.
Source and scope of the change
Corpus Christi Water officials say the change in taste and smell was caused by naturally occurring organic material that entered the municipal supply after moving from western reservoirs into the system via the Nueces River. That material reached the city's O.N. Stevens Water Treatment Plant last week and produced the noticeable odor and taste reported by residents.
What the utility is monitoring
City crews reported that those organic compounds were no longer being detected in water entering the treatment plant as of Thursday afternoon. However, water that already had been treated and placed into the distribution system remains in pipes and could carry the odor and taste for several days in some neighborhoods.
Corpus Christi Water is continuing to sample and monitor water quality across the system and says the tap water remains safe to use. Residents with concerns have been directed to call the city's 3-1-1 line, or to follow the recorded instructions if calling after business hours.
"The water remains safe to use."
Why some areas will smell it longer
How long the odor persists in a given neighborhood depends on how quickly water moves through that part of the distribution network. City officials said most areas should see improvements by early this week, but emphasized that some neighborhoods could take longer depending on local flow patterns and how much water with the odor had already filled nearby pipes.
- Initial alert: City first notified residents of the unusual taste and odor on Sept. 16.
- Detection at treatment plant: Organic compounds reached the O.N. Stevens Water Treatment Plant last week.
- Recent status: Compounds not detected entering the plant as of Thursday afternoon.
Maintenance limits typical remedies
Utilities commonly respond to taste and odor complaints by flushing lines to move affected water out of the distribution system. Corpus Christi Water said it is not recommending flushing at this time because crews are working on repairs to the Mary Rhodes Pipeline. That work reduces the city's ability to carry out widespread flushing without risking service interruptions.
The city reiterated that, despite the sensory change, there is no indication of a public health risk connected to the taste or odor event. Officials said monitoring continues and they will provide updates to residents as conditions change.
| Item | Status |
|---|---|
| First city alert | Sept. 16 |
| Organics detected at treatment plant | Last week |
| Compounds no longer detected entering plant | As of Thursday afternoon |
| Recommendation to residents | Water safe to use; call 3-1-1 with concerns |
Residents who continue to notice an earthy taste or smell in their tap water should allow their cold water to run for a few minutes to see if fresher water reaches their tap; however, the city has not advised widespread flushing by the public because of the ongoing pipeline repairs. For persistent issues at a single home or building, callers are encouraged to contact 3-1-1 so crews can evaluate localized conditions.
City utilities officials will post additional guidance and updates as monitoring results become available. In the meantime, the department is urging patience as the distribution system clears and repairs to the Mary Rhodes Pipeline continue.
