DRY BRANCH, W.Va.- For Bonnie Wireman, the white plastic bag covering her kitchen faucet is a reminder that she can't drink the water.
The 81-year-old woman placed it there after forgetting several times the tap water was tainted after a coal processing chemical leaked into the area's water supply. Every time she turned on the water, she quickly stopped and cleaned her hands with peroxide - just to make sure she was safe.
The widow of a coal miner, Wireman was angered about the chemical spill that's deprived 300,000 West Virginians of clean tap water for four days, but doesn't blame the coal or chemical industries.
Employees of the South Charleston Public Works Department assist residents in obtaining cases of water and filling the containers they brought with them Sunday after a chemical spill Thursday in the Elk River that has contaminated the public water supply in nine counties.
"I hope this doesn't hurt coal," said Wireman, who lives in an area known as Chemical Valley because of all the plants nearby. "Too many West Virginians depend on coal and chemicals. We need those jobs."
And that's the dilemma for many West Virginians: The industries provide thousands of good paying jobs but also pose risks for the communities surrounding them, such as the chemical spill or coal mine disasters. The current emergency began Thursday after a foaming agent used in coal processing escaped from a Freedom Industries plant in Charleston and seeped into the Elk River. Since then, residents have been ordered not to use tap water for anything but flushing toilets.
Gov. Earl Ray Tomblin said Sunday water tests were encouraging, but he didn't give a timetable for when people might be able to use water again.
"The numbers look good. They are very encouraging," Tomblin said.
Schools, restaurants and other businesses were to close Monday, but the governor said all state offices would be open.
Maj. Gen. James Hoyer, of the West Virginia National Guard, said testing near the water treatment facility has consistently been below one part per million for 24 hours, a key step officials needed before they can lift the ban. Some tests have shown the chemical was not present at all in water coming in and out of the plant.
West Virginia American Water President Jeff McIntyre said they will lift the water bans by zone, but he didn't say how soon it would be.
West Virginia is a picturesque, mountainous state, with deep rivers and streams that cut through lush valleys. But along the twisting, rural roads there are signs of the state's industrial past and present: Chemical plant storage tanks rise from the valley floor. Coal mines - with heavy equipment and steel structures used to extract and then transport the fuel - are part of the rural landscape. White plumes of smoke drifting from factories offer a stark contrast to the state's natural beauty.
"You won't find many people in these parts who are against these industries. But we have to do a better job of regulating them," said Wireman's son, Danny Scott, 59, a retired General Electric worker who has been helping take care of his mother. "The state has a lot to offer. We don't want to destroy it."
West Virginia is the second-largest coal producing state behind Wyoming, with 538 mines and 26,619 people. The state has about 150 chemical companies that employ 12,000 workers.
Over the years, there have been accidents in both industries that have killed workers and harmed the environment. In January 2010, a worker died at a DuPont plant after inhaling a lethal dose of phosgene, which was used as a chemical weapon during World War I and today is used as a building block in synthesis of pharmaceuticals and other organic compounds. An explosion at the Upper Big Branch coal mine killed 29 people in 2010.
