After E.coli bacteria were found in a test sample from a well field on Wednesday, the South Broward public water supply was declared unsafe and residents of the area were warned to avoid tap water, or to boil it before use.
Bottled water has long since disappeared from the shelves of stores, as the Sun-Sentinel reports, and warning signs are everywhere at the airport, hospitals and other public places.
Dr. Nabil el-Sanadi, the county emergency medicine director, said the danger is primarily to those with weakened immune systems, as CBS Miami reports.
Health officials hoped to be able to lift the warning on Friday after new tests are complete.
