(WCHS/CNN) - Residents in Charleston, WV, are still feeling the impact from last month's chemical contamination of their drinking water supply.
Three more schools in Kanawha County closed their doors Thursday, dismissing students early. That's in addition to the two schools that closed on Wednesday.
The lingering smell of licorice in the water prompted the closures.
That smell is the first indication residents had last month that their water was tainted.
A methanol compound leaked from a tank farm upstream from Charleston in early January, contaminating the drinking water of more than a quarter million people.
A federal investigation into the spill is now under way.
