Environmental Effects Of Tar Sands On Water

Water facts:-Essential for life.-The more humans on earth, the more water is required.-Water is home to many creatures amongst the Earth.-Many people in poorer nations have no access to clean drinking water.

-Composed of sand and shale particles coated with bitumen, a viscious mixture of long-chain hydrocarbons. (p. 432-chapter 19, Environmental Science: A Global Concern)-Good source to get energy from for the amount of work extracted oil does.-Alberta, Canada has the largest amount of tar sands. -About two tonnes of tar sand is required to produce one barrel of oil.-Cause environmental issues:1. Green house gas emissions2. Land destruction3. Social changes in near communities4. Plenty of water is used to extract oil from tar sands.

Tar Sands & Water

Water is needed to produce oil from tar sands. The Environmental issue in regards to that is, water contamination. The majority of this water is stored in a tailing pond. Nearby communities of humans and ecosystems get disrupted. Storing contaminated water in a separate pile seems like the proper way of dealing with this. These lagoons, sewages, tail ponds pose a hazard.

"Quit extracting oil from tar sands and switch to a greener source of energy.""Fossil fuels out compete green energy for the amount of oil needed to do work."

-Naphthenic acid, a natural constituent of petroleum that becomes dissolved and concentrated in the hot water used to process the tar sands. (greenpeace.org)-Makes other toxic chemicals in pond highly concentrated.-Hard to get rid of within the water.-Harms microorganisms living in water-Leaks into groundwater underneath tail ponds, linked to human health problems; liver damage.-Small portions of Naphthenic acid eventually leak into fresh water supplies.

Tail Ponds

Above is a video in regards to tail ponds. Pretty much where waste goes after extracting oil from tar sands. Not only are insects, microorganisms living in waters/land affected. Clearly birds who migrate back to Northern Territories as well are impacted. This is not good for the bird population.

If water is so valuable. Why is the water use being used foolishly? Rather than dealing with a water shortage in the future, we should be preserving it now.
