More West Virginia customers cleared to drink tap water after spill

By Karen Brooks
    Jan 15 (Reuters) - West Virginia officials on Wednesday gave
more residents the green light to drink tap water after a
chemical spill that fouled drinking water for hundreds of
thousands of people across the state.
    Some 51,000 water customers are now cleared to drink or wash
with tap water after nearly a week without it, according to a
statement by West Virginia American Water.
    Consumers were instructed to flush their systems before
using the water, which had been barred for use except for
toilets since the chemical discharge into the Elk River on
    More than 300,000 consumers were affected after as much as
7,500 gallons (28,000 liters) of 4-methylcyclohexane methanol,
or crude MCHM, leaked into the river.
    Officials have said it might be several days before the
entire system, with its hundreds of miles (km) of pipe, was safe
to use.
    The crude MCHM chemical, which is used in coal processing,
leaked into the river from a tank at a Freedom Industries site
about a mile (1.6 km) upriver from an American Water treatment
plant, the biggest in the state.
    Freedom Industries, which makes specialty chemicals for the
cement, mining and steel industries, has apologized for the
    Water tainted by crude MCHM smells faintly of licorice.
Contact with the water can cause nausea, vomiting, dizziness,
diarrhea, rashes and reddened skin.
    The tainted water has flowed downstream into the Ohio River,
and utility spokesmen in Kentucky and Ohio said they were
monitoring water quality to be sure consumers were not affected.
    The U.S. Chemical Safety Board and the U.S. attorney for the
Southern District of West Virginia are investigating the spill.
