Williams Energy and state regulators are working to mitigate the impact of a natural gas pipeline rupture in Marshall County.
Department of Environmental Protection spokeswoman Kelley Gillenwater says inspectors have found benzene and other materials in an unnamed stream.
Gillenwater tells The Intelligencer and Wheeling News-Register that the company has contained the contaminants to the stream. None of the materials has been found in Little Grave Creek.
Gillenwater says Williams Energy also is removing contaminated soil in the area of the spill.
About 132 gallons of condensate spilled into Little Grave Creek after a 4-inch pipeline ruptured northeast of Glen Dale on April 9. Condensate is a mixture of petroleum products found in natural gas.
