The first four zones of West Virginia American Water Company customers, part of the areas in nine counties that have been under a do-not-use order since Thursday night, were cleared to begin a prescribed flushing process on Monday.
Those areas were in Downtown Charleston from the Elk River east to the
“We’re finally at a point where the do-not-use order is being lifted in certain areas,” announced Governor Earl Ray Tomblin on Monday.
The flushing process for homes and businesses involves three steps: running all hot water taps for 15 minutes, running all cold water taps for five minutes and then running all remaining faucets, including those outside, and appliances for five minutes.
“Only customers located within zones that have been lifted should begin flushing. If we have problems with pressure in the system, we will not be able to open up additional zones until those pressures are restored,” said Jeff McIntyre, president of West Virginia American Water.
He said the timetable for fully restoring service for all customers would depend on ongoing chemical tests in the individual zones and the demand on the system as more and more homes and businesses resume normal water usage.
“If all the customers in the entire system, or even in small zones, opened all their taps at the same time, they could use ten to 20 times of the water that we can produce in a day,” said McIntyre of the reasoning behind the zone opening process.
“You will extend the time of recovery if you flush too early. You will cost yourself money and you will waste your effort because you’ll be doing it before the water is safe,” said McIntyre to the thousands of people who will have to wait.
Even after flushing, McIntyre said there could be a lingering licorice-like smell, which is expected, but not considered a health issue, since the odor threshold for the chemical that prompted the do-not-use water order is about ten times lower than what is considered a safe level for drinking water.
An estimated 7,500 gallons of crude MCHM, made up primarily of 4-methylcylohexane methane, leaked from a storage tank at Freedom Industries along the Elk River in
On the interactive map, water usage is allowed in the blue zones, following flushing, while the do-not-use order is still in effect for the red zones. The “go” zones were changed from green to blue to assist people who are colorblind.
Automated phone calls are also going out to those in zones that are cleared for water restarts.
“We’ve made a lot of progress, but I ask all
