It could be days before clean tap water is flowing again to several hundred thousand people in West Virginia following a chemical spill.
State officials met Saturday to discuss plans for flushing a West Virginia American Water system contaminated by Thursday's spill.
West Virginia American Water President Jeff McIntyre said at a news conference that sample test results must consistently show the chemical's presence is at or below a safe level before residents can resume using tap water.
The company issued the order Thursday after a chemical used to process coal spilled from a Freedom Industries plant into the Elk River in Charleston. The order applies to about 300,000 people.
A handful of people have been hospitalized since the spill.
