About seven weeks have passed since Greenville restaurants and some day cares were shut down, and people were told the water could be contaminated. Greenville Utilities Commission said people should boil their water or use bottled water after fecal coliform was found in a sample near County Home Rd. Back then, officials didn't know what caused the bacterial contamination. Today, the exact cause is not still not clear.
Greenville Utilities says their investigation has determined that the contamination was a one-time event, not an ongoing problem. GUC says they ruled out nearly every possibility for why the water got contaminated, and its possible that the culprit could have been "backflow." In a nutshell, that's when water flows the wrong way. Several simple scenarios can cause backflow, along with new construction.
GUC says they're now doing more water sampling and pressure tests than ever before to make the water in Greenville safer.
