A landslide caused a pipeline to rupture and spill a liquid gas near a Wetzel County stream over the weekend.
Kathy Cosco of the West Virginia Department of Environmental Protection said officials have not been able to take samples at the Rocky Run area where the spill occurred because gas levels remained too high.
Cosco said Friday that the MarkWest Energy pipeline carried an unspecified "wet gas." She says many natural gas liquids, which are byproducts of natural gas drilling, vaporize when they come into contact with water. Evidence of a fish kill was found, but Cosco says no residents live close enough to the site to be in danger.
A MarkWest spokesman says the 10-inch, 27-mile pipeline will remain shut down until repairs are made.
