The water is bad in West Virginia

The nation has its eyes on a nine-county area in West Virginia that’s under a state of emergency. A coal-processing chemical leaked into a river and poisoned the drinking water there. Cleanup is ongoing. As they attempt to flush the chemical out of their drinking water systems, officials are trying to determine what level of the chemical is safe.

Ken Ward Jr. of the West Virgina Gazette reports that local and federal officials are saying that "1 part per million" of  crude 4-methylcyclohexanemethanol (the coal processing chemical) is safe for people to drink.

But Ward is having a tough time finding out what they based that number on:
