Map shows the estimated location of thousands of abandoned wells
An abandoned gas well is likely the source of the hydrogen sulfide gas that was detected ahead of an explosion in Wheatley,Ont., according to Chatham-Kent officials.
The blast injured 20 people and reduced two buildings in the downtown core to rubble.
CBC Windsor has learned there are thousands of abandoned natural gas and oil wells across the province.

Old oil and gas wells are typically decommissioned by capping and pouring cement, Scott Mundle, one of Canada's foremost experts in identifying gases from abandoned wells, told CBC Radio's Windsor Morning in June.
Hydrogen sulphide is present in naturally occurring reservoirs as well as in sewer gas. It is flammable and highly toxic, he said.
