USGS Release: East Poplar Brine-Contaminated Groundwater Plumes Continue to Move (4/2/2014 11:00:00 AM)

HELENA, Mont. – A new report by the U.S. Geological Survey describes the extent and movement of contamination in the East Poplar oil field area in northeastern Montana. The contamination in shallow groundwater and the Poplar River is brine, which is saltier than seawater and is a byproduct as part of the process of extracting crude oil in the East Poplar oil field. The study determined likely source areas, brine plume extents, and movement of the plumes.
