Is the chlorine level tested during this period?

Yes, chlorine is tested, and many other compounds in water are monitored continuously. North Texas Municipal Water District (NTMWD) conducts a quarter-million tests each year in a state-certified laboratory to monitor, regulate, and report water quality. In some cases, NTMWD is voluntarily increasing the frequency of testing above what is required. During the disinfectant change in 2018, the Texas Commission on Environmental Quality (TCEQ) also collected 117 samples from 31 public water systems that deliver NTMWD water to confirm compliance.
