Leaks found in shale-gas wells in Quebec

Natural resources inspectors have discovered 11 incidences of natural gas migrating outside of shale gas wells in Quebec. All of the wells are considered to be in an “acceptable” state, and the inspector’s report says the leaks are normal and located far away from residences. However, the report also expresses concern about the release of greenhouse gas and how the leaks could potentially contaminate aquifers or, under the right conditions, cause explosions. An additional eight wells also had leaks, but they were contained within a protective casing and did not reach the surrounding environment.
