Syncrude Tailings Dam
The name Syncrude Tailings Dam often refers to the Mildred Lake Settling Basin (MLSB). This is an embankment dam that is, by volume of construction material, the largest earth structure in the world in 2001. It is located north of Fort McMurray, Alberta, Canada at the northern end of the Mildred Lake lease owned by Syncrude Canada Ltd.. The dam and the tailings artificial lake within it are constructed and maintained as part of ongoing operations by Syncrude in extracting oil from the Athabasca Oil Sands. Other tailings dams constructed and operated in the same area by Syncrude include the Southwest Sand Storage (SWSS),〔 which is the third largest dam in the world by volume of construction material after the Tarbela Dam.

According to Canada’s Oil Sands Innovation Alliance (COSIA), an alliance of oil sands producers formed in 2012, who share research on Environmental Priority Areas (EPAs) such as tailing pond water and greenhouse gases, "Tailings are the sand, silt, clay and water found naturally in oil sands that remain following the mining and bitumen extraction process."〔(【引用サイトリンク】publisher=Canada’s Oil Sands Innovation Alliance (COSIA) )〕 The hot water process used by Suncor and Syncrude in their open-pit mining operations, to extract bitumen from the Athabasca Oil Sands (AOS) produces large quantities of tailings pond sludge which remains stable for decades. By 1990 it was considered to be the "imminent environmental constraint to future use of the hot water process." Oil sands tailings pond water contains toxic chemicals such as "naphthenic acids (NAs) and process chemicals (e.g., alkyl sulphates, quaternary ammonium compounds, and alkylphenol ethoxylates)."
