Tar sands oil quality
Oil sands, also known as "tar sands," are sediments or sedimentary rocks composed of sand, clay minerals, water, and bitumen. The oil is in the form of bitumen, a very heavy liquid or sticky black solid with a low melting temperature. Oil production from tar sands uses large amounts of land (for open-pit mining), water, and energy, when compared to other oil resources. Open-pit mining also produces a lot of waste (leftover sand, clays, and contaminants contained within the tar sands) that may pose a risk to nearby water supplies. On a lifetime basis, a gallon of gasoline made from tar sands produces about 15% more carbon dioxide emissions than one made from conventional oil. This important difference is attributable to the energy intensive extraction, upgrading, and refining process. Oil sands, sometimes referred to as tar sands, is a mixture of sand, clay, other minerals, water, and bitumen. The bitumen is a form of crude oil that can be separated out from the mixture. In its natural state, it is very dense and highly viscous. Tar sands yield a heavy, thick, low-quality oil that requires significantly more energy to extract and refine than conventional crude.
Water Monitoring and Testing in the Oil Sands. A Surface Water Quality Management Framework was developed as part of the Lower Athabasca Regional Plan (LARP). Water quality triggers and limits are identified to give advance notice of unfavourable trends and establish water quality limits that must not be exceeded.
