The Oklahoma Department of Environmental Quality (DEQ) has announced that the boil order for the Cardinal Hill Public Water Supply (PWS), located in Marshall County, has been lifted.
The water is now safe for human consumption. The order to boil water was issued due to the presence of E. coli. State and federal
regulations require that customers be notified if, at any time, public drinking water is determined to be unsafe.
DEQ is responsible for regulating more than 1,600 public water supplies in the State of Oklahoma. All public water supplies are required to regularly submit samples to DEQ for routine testing to ensure that water is safe for human consumption.
