Williams Energy won't be cited by state environmental regulators for a natural gas pipeline explosion in Marshall County.
The April 5 explosion and fire scorched trees over a 2-acre area near Moundsville. Several homes were evacuated as a precaution.
Department of Environmental Protection spokeswoman Kelley Gillenwater tells The Intelligencer and Wheeling News-Register that the agency didn't find any evidence of groundwater contamination at the site.
An investigation of the explosion's cause is continuing.
Gillenwater says the rupture most likely occurred at a weld point in the 12-inch pipeline.
Williams Energy spokeswoman Helen Humphreys says her company appreciates the DEP's evaluation.
