Environmental repercussions of the tar sands

This is a result of the huge amount of energy primarily from burning natural gas required to generate the heat needed to extract bitumen from the tar sands and upgrade it into synthetic crude. At the same time we need to speed the implementation of real solutions.

These operations are located much farther from the river and, as a result, rely mainly upon groundwater.

For certain in situ drilling operations, significant amounts of water are required to create steam to be injected underground.

About two tons of tar sands are required to produce one barrel of oil. Nonetheless, the government has failed to implement regulations that would require tar sands withdrawals to stop when the health of the river is at risk.

The science of climate change demands that we rapidly transition away from fossil fuels, meaning there would be no future for the tar sands. Tar sands are an increasingly common—but expensive and dirty—source of oil.

Modelling of the impacts of approved tar sands development, which includes three operating mines and three operations at various stages of planning and construction, shows that maximum predicted ambient air concentrations of NOX and SO2 would exceed provincial, national and international guidelines.

Because the steam condenses into water and is pumped up with the bitumen, the water can be recycled. There are over sq. Environmental impacts of tar sands Surface mining versus in situ tar sands extraction.

Oil Sands Truth

It is projected that tar sands production will reach million barrels per day by and could grow to 5 million barrels per day byif not sooner. Pembina Institute Tar sands also known as oil sands are a mixture of mostly sand, clay, water, and a thick, molasses-like substance called bitumen.

According to Environment Canada the Canadian equivalent to the U.

Environmental health risks of Alberta oil sands likely underestimated: study

But because they require fresh water, the salty water must be treated, which produces large amounts of waste sludge that must be disposed of. Regulations introduced in early are so fraught with loopholes and gaps that greenhouse gas pollution from tar sands is predicted to triple by Most of us regard addictions to anything as inherently unhealthy and admission of the problem as the first step toward getting clean.

Canada exports 66 percent of its domestic crude oil production and since the United States has received 99 percent of these exports. The pipelines would trample Treaty and Indigenous rights, endanger the water supply of millions of people across the country, and lock us into a high carbon resource for decades to come.

The governments of the United States and Canada must collectively commit to implementing regulations that will make North America a global leader in fuel efficiency.

The current technology, which has evolved relatively little since it was first developed in the early 20th century, is a hot-water-based separation process that requires huge quantities of water and energy see diagram. It also passes directly through the boreal forest being cleared and strip-mined, and serves as the primary source of water used to separate the bitumen from the mined tar sands.

Growing awareness about the global warming and environmental consequences of relying upon growth in tar sands production throws into sharp relief the perils of our addiction to oil in the 21st century. SinceAlberta has been the industrial air pollution capital of Canada. It also passes directly through the boreal forest being cleared and strip-mined, and serves as the primary source of water used to separate the bitumen from the mined tar sands.

Some of these extraction methods require large amounts of both water and energy for heating and pumping. These techniques include steam injection, solvent injection, and firefloods, in which oxygen is injected and part of the resource burned to provide heat.

The Harm the Tar Sands Will Do

One of the most important ones right now is to stop the proposed pipelines from ever getting built. What do you consider is the greatest achievement so far in your activist life? For certain in situ drilling operations, significant amounts of water are required to create steam to be injected underground.

The tar sands mining procedure releases at least three times the CO2 emissions as regular oil production and is slated to become the single largest industrial contributor in North America to Climate Change.

Regulations introduced in early are so fraught with loopholes and gaps that greenhouse gas pollution from tar sands is predicted to triple by Blake walked out of class by himself. The fires that raged through Alberta and forced tens of thousands from their homes is a sign of climate change and a warning of what is to become far more frequent the longer we fail to act.

In fact, the government explicitly allows the tar sands industry to continue withdrawing water no matter how low the river flows become. Story continues below advertisement "Our study shows that emissions of PAH estimated in environmental impact assessments conducted to approve developments in the Athabasca oilsands region are likely too low," reads the study published Monday in the U.

Tar Sands Fever

It is the prospect of this growth that has led Canadian Prime Minister Stephen Harper to label Canada an "emerging energy superpower. This important difference is attributable to the energy intensive extraction, upgrading, and refining process. Using computer models, researchers studied emissions estimates from environmental reports to predict chemical concentrations from direct oilsands industrial activity such as mining, processing and vehicle traffic.

Since Alberta has been the industrial air pollution capital of Canada. The tar sands industry is now focused on quintupling production as quickly as possible. But with growing reliance on this source of oil, numerous American refineries are converting or expanding in order to handle tar sands-derived synthetic crude oil or raw bitumen.Mining Tar Sands Produces Much More Air Pollution Than We Thought Research shows that emissions of a class of air pollutants are two to three orders of magnitude.

The tar sands are the largest industrial, capital and energy project on the planet with the environmental and human rights impacts to match. Oversq. km, an area the size of Florida, are available for tar sands leasing. Tar Sands The majority of oil used by the United States as well as internationally soon may come from the tar sands in Alberta, Canada.

Extracting oil from tar sands is an extremely costly and immensely dirty way of obtaining fuel. The following pictures show oil mining, where the sand is dug from the ground and the oil's separated through a lengthy and messy process. There are drilling sites in the oil sands, and those are highlighted in the photo essay at the end of this one.

A new study suggests the environmental health risks of oilsands operations in Alberta's Athabasca region have probably been underestimated. Researchers say emissions of potentially hazardous air pollution that were used in environmental reviews done before approving some projects did not include evaporation from tailings ponds or other.
