Canada Study Shows NatGas Pollutes Groundwater
Methane Leaks from Energy Wells Affects Groundwater, Travels Great Distances, Study Confirms; Researchers call for effective monitoring in Canada.

“…[M]ethane gas leaking from energy industry wells can travel great distances in groundwater and pose safety risks, contaminate water, and contribute to climate change…[and] current monitoring for gas leakage, usually at ground level and adjacent to wells, is inadequate to detect contamination [according to Mobility and persistence of methane in groundwater in a controlled-release field experiment]…British Columbia’s floundering shale gas industry has drilled and fracked nearly 10,000 wells in northeastern B.C. over the last decade, causing more than 1,000 earthquakes in the region. Impacts on groundwater are not being systematically monitored…[Researchers tracked] injected methane for more than eight months via monitoring wells as the explosive gas travelled through the ground, entered the atmosphere or dissolved into groundwater, causing subtle but important changes to water chemistry…” click here for more
