Acute MCL Coliform
Violation
Within 24 hours of becoming aware of the sample results causing
an
Acute MCL violation, the public water system (PWS) official
must notify their customers using the mandatory language for
issuing an Acute MCL public notification and boil water
notification. The PWS must also contact TCEQ and inform them of the
fecal coliform/E. coli results within 24 hours of the laboratory
notification of the results. If the agency is closed, then you must
notify them of the results no later than the next business day.
Please refer to 30 TAC 290.122 for more information on issuing the
