CHARLESTON, W.Va. (AP) — There may be a light at the end of the tunnel for about 300,000 West Virginians in nine counties who are into a fifth day of using bottled water to wash, cook and brush their teeth due to a leaked chemical.

Over the weekend, tests showed levels of the licorice-smelling chemical used in coal processing were consistently below a toxic threshold.

Officials won't say a water use ban will be lifted today, but they expect it to be soon.
