Mandatory Language for Monitoring and Reporting Violation
Chemical Sampling
CHEMICAL MONITORING, ROUTINE MAJOR
The HARRIS COUNTY MUNICIPAL UTILITY DISTRICT 418 water system PWSID: TX1013329 has violated the monitoring and reporting requirements set by Texas Commission on Environmental Quality (TCEQ) in Chapter 30, Section 290, Subchapter F. Public water systems are required to collect and submit chemical samples of water provided to their customers, and report the results of those samples to the TCEQ on a regular basis.
We failed to monitor and/or report the following constituents: Asbestos
This violation occurred in the monitoring period 01/01/2022-12/31/2024.
Results of regular monitoring are an indicator of whether or not your drinking water is safe from chemical contamination. We did not complete all monitoring and/or reporting for chemical constituents, and therefore TCEQ cannot be sure of the safety of your drinking water during that time.
We are taking the following actions to address this issue: Harris County MUD 418 completed the required sampling for asbestos during the time period mentioned above, 01/01/2022-12/31/2024. The District failed to pay the invoice on time for this sampling, which delayed the reporting of these results, and caused TCEQ to issue this violation requiring this public notice. All results were within the limits set forth by the TCEQ.
Please share this information with all people who drink this water, especially those who may not have received this notice directly (i.e., people in apartments, nursing homes, schools, and businesses.) You can do this by posting this notice in a public place or distributing copies by hand or mail.
If you have questions regarding this matter, you may contact Melissa Kapsen with Municipal District Services, the operator for Harris County MUD 418, at 281-290-6500.
