CHARLESTON, WV - JANUARY 10: Freedom Industries on Barlow St on the banks of the Elk River is seen on January 10, 2014 in Charleston, West Virginia. West Virginia American Water determined Thursday MCHM chemical had 'overwhelmed' the plant's capacity to keep it out of the water from a spill at Freedom Industries in Charleston. An unknown amount of the hazardous chemical contaminated the public water system for potentially 300,000 people in West Virginia. National Journal

Students at a handful of schools in Charleston, W.Va., were sent home last week amid reports of potential water contamination following a chemical spill last month, The New York Times reports.

Students were told to leave after students and faculty noticed the smell of licorice, a distinct odor given off by the chemical MCHM that made its way into the state's Elk River when a chemical storage tank leaked last month.

Testing at the schools that either sent students home or closed entirely indicated that levels of MCHM in the water did not pose a threat to public health. But West Virginia residents remain skeptical.

"If one smells the odor, people know the chemical is in the water," said Dr. Rahul Gupta, the director of the Kanawha-Charleston Health Department. "It's difficult for a lot of people to drink it even if they agree with the science behind it."
