How is water managed? In Alberta , if water is removed from a coal seam, it may be discharged. In the case of saline water, it must be reinjected back into formations approved by government regulators. These formations are not connected to any fresh water sources.
Horseshoe Canyon Coals
• These coals are ‘dry’ meaning they store little to no water and do not produce water as part of the extraction process.
• These coals are being drilled at shallow depths and require minimal permanent surface equipment.
Mannville Coals
• Where these coals are currently being tested they produce saline water (two to three times as salty as ocean water). Alberta regulations require that the produced water from this zone must be re-injected back into the ground in an approved formation.
