"The primary source of contamination from the companies' oil production near Poplar is brine — essentially salty water with elevated levels of metals and toxins, including benzene and toluene.
The EPA and USGS have been tracking the spread of an underground plume of contamination from the East Poplar oil field for decades. This is the first time the plume has reached public wells.
The wells serve about 3,000 people in and around Poplar, the seat of the Fort Peck Assiniboine and Sioux Tribes." ============
tolulene and benzene are basically paint thinner if I remember my chemistry. Back in the 1980's they were using tolulene as fuel for Formula-1 race cars. In Ozland they still try to slip it into gasoline for better performance. You don't want to breath any of it. God help those indians if it's in their drinking water.
