Failure to Submit a Disinfectant Level Quarterly Operating Report (DLQOR)



The SEIS LAGOS UTILITY DISTRICT water system PWS ID 0430057 has

violated the monitoring and reporting requirements set by Texas Commission on

Environmental Quality (TCEQ) in Title 30, Texas Administrative Code (30 TAC),

Section 290, Subchapter F. Public water systems are required to properly disinfect

water before distribution, maintain acceptable disinfection residuals within the

distribution system, monitor the disinfectant residual at various locations

throughout the distribution system, and report the results of that monitoring to the

TCEQ on a quarterly basis.


Results of regular monitoring are an indicator of whether or not your drinking

water is safe from microbial contamination.


  • Submit the report to 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 any questions regarding this matter, you may contact Dewane at (972)

442-6875, the Seis Lagos Utility District business office.
