Update to Publication Boil Water Notice

Figure: 30 TAC §290.47(c)(3)
Boil Water Notice Rescinded
12/03/2025

On 12/02/2025, the Texas Commission on Environmental Quality required the Harlingen Waterworks System public water system, TX 0310002 to issue a Boil Water Notice to inform customers, individuals, or employees that due to conditions which occurred recently in the public water system, the water from this public water system was required to be boiled prior to use for drinking water or human consumption purposes.

The public water system has taken the necessary corrective actions to restore the quality of the water distributed by this public water system used for drinking water or human consumption purposes and has provided TCEQ with laboratory test results that indicate that the water no longer requires boiling prior to use as of 12/03/2025

If you have questions concerning this matter, you may contact Water Services Director Mario A. Gonzalez at (956) 564-0450.
