The “no swimming” advisory was issued after approximately 73,000 gallons of partially treated wastewater discharged to McDowell Creek Cove on Mountain Island Lake on March 26, 2014 at 4901 Neck Road. The discharge was caused by a brief power failure on the disinfection system at the McDowell Creek Wastewater Treatment Plant. Charlotte-Mecklenburg Utilities staff immediately diverted flow in to storage basins until the disinfection process was back on-line.
Water samples will be collected by Charlotte-Mecklenburg Storm Water Services staff. Sampling will continue until levels of fecal coliform bacteria fall below 200-colonies/100 ml, which is the level determined to be safe for swimming. When bacteria counts reach this level, the no swimming advisory will be lifted.
Rusty Rozzelle, Charlotte-Mecklenburg Storm Water Services’ Water Quality program manager, said the advisory is standard procedure. "It was necessary to close the areas to recreation because of the potential risk to human health as Mountain Island Lake is designated as recreational waters,” said Rozzelle.
