Marietta Times, 2-14-13: “A New Matamoras man has pleaded guilty to a violation of the Clean Water Act by allowing oil and gas well wastewater to flow into a tributary of the Little Muskingum River three years ago….

…The reservoir contained about 800,000 gallons of wastewater at the time, most of which entered Rockcamp Run.

Analysis of wastewater from the reservoir showed significant concentrations of barium and sodium.

Ingesting drinking water containing higher levels of barium than the U.S. Environmental Protection Agency drinking water guidelines of 20 milligrams per liter can cause gastrointestinal disturbances and muscle weakness with short-term exposure and kidney damage over a longer period of time.”  more
