A Texas-based oil and gas company is monitoring air and water quality in Alberta, Canada after its fourth chemical spill in the past year, according to a report from the Northern Journal.
An employee from Apache Corp. recently discovered that an injection well was leaking waste water onto the landscape and into a small creek nearby.
Air quality monitoring at the site has indicated that the waste water is not emitting hydrogen sulfide, a toxic chemical used in oil and gas production. The company will install real time monitoring stations at nine water injection wells.
Three other waste water spills have occurred in the past year in Apache facilities, including one which emitted 15.4 million liters of waste water into 42 hectares of wetlands.
