There was a release of heat transfer oil at the Mobley gas processing facility in Wetzel County, West Virginia, Saturday.
MarkWest Energy Partners said the oil has reached the North Fork of Fishing Creek, near Pine Grove, WV.
The mayor of Pine Grove alerted residents not to drink or use the water until water officials can test it. As a result, residents can pick up bottled water at a local community center.
Federal and state regulatory agencies have been notified and MarkWest is coordinating its response efforts with the agencies and local officials. MarkWest is working with environmental professionals and has deployed protective booms in the creek at various locations.
Officials closed the Pine Grove Water Works water intake located downstream from the release site and Pine Grove has switched over to an alternate source of water as a precaution.
