Frac Sand Health and Environmental Impacts

Sand is critical to fracking. After workers drill down into rock, they create fractures jetstream mining pumping in a mixture of water, chemicals and sand. The sand keeps the cracks propped open so that oil and gas are released.

Frac sand mining creates significant air pollution from the handling, mining, and processing of the sand. The important sources of air emissions come from the tiny dust particles - known as particulate matter - scattered during mining and processing.

These tiny dust particles, usually only a few microns in diameter, when inhaled in the lungs can lead to Silicosis - cancer of the lungs that poses a danger to miners and nearby communities.

The chronic silicosis caused by silica exposure poses unique dangers for employees working at frac sand mining sites, what is oil sand mining. Because long-term exposure can be fatal, the Labor Department’s Occupational Safety and Health Administration (OSHA) issued draft regulations designed to reduce the health risk and previously issued a hazard alert.

Sand is basically silica — and breathing in silica is one of the oldest known workplace dangers. Inside the lungs, exposure to the tiny particles has been shown to sometimes lead to serious lung diseases like silicosis and lung cancer.

Workplace safety expert Eric Esswein and his team visited 11 fracking sites in five states: Arkansas, Colorado, North Dakota, Pennsylvania and Texas. At every site, the what is oil sand mining found high levels of silica in the air. It turned out that 79 percent of the collected samples exceeded the recommended exposure limit set by the National Institute for Occupational Safety and Health.

There were some controls in place, what is oil sand mining Esswein, who notes that "at every site that we went to, workers wore respirators."

But about a third of the air samples they collected had such high levels of silica, that the type of respirators typically worn wouldn't offer enough protection.

Neighbors fear for their health

Wisconsinites and Minnesotans (the two states producing most of the frac sand) who live around frac sand mining, processing and transportation facilities are concerned about the long term impacts of their exposure to silica dust.

As a result, some local governments have enacted bans and moratoria.

Mining puts water at risk

Frac sand processing also poses dangers to water sources. Miners commonly use chemicals called flocculants to clean, wash, or remove unwanted minerals or other fine particles from the processed sand. These chemicals can infiltrate in to groundwater after washing.

Long term exposure to common flocculants like polyacrylamides and acrylamides in high concentrations of drinking water can lead to nervous system, blood problems or increased risk of cancer. 

Neither the federal nor state governments have developed drinking water standards for flocculants.

Mining refers to the oil sands extraction process whereby large amounts of earth are removed, mixed with water and transported by pipeline to a plant, where the bitumen is separated.

Oil Sands Mining

Definition

Oil sands are a mixture of sand, water, clay and bitumen found in several locations around the globe, with the largest reserve located in Alberta, Canada. Oil sand can be upgraded into synthetic crude oil and other petroleum products[1]Alberta Energy. What is Oil Sands? (2015). Retrieved from http://www.energy.gov.ab.ca/oilsands/793.asp Alberta Energy. What is Oil Sands? (2015). Retrieved from http://www.energy.gov.ab.ca/oilsands/793.asp Alberta Energy. What is Oil Sands? (2015).

(2015). Retrieved from http://www.energy.gov.ab.ca/oilsands/793.asp .

There are two different methods of producing oil from oil sands: open-pit mining and in situ. Bitumen that is close to the surface (less than 75 metres) is mined. Approximately 20% of oil sands are recoverable through open-pit mining.

Bitumen is extremely thick and too heavy to flow or be pumped, and therefore requires dilution and/or heating during the production process.

Open pit mining is similar to coalmining operations – large shovels scoop the oil sand into trucks that then take it to crushers where the large clumps of earth are broken down. This mixture is then mixed with water to form a slurry that is transported to a plant, where the bitumen is separated from the other components in a froth process. Bitumen normally undergoes a process called upgrading to create synthetic oil that can be refined. 

 

 

Context

In general, unconventional forms of oil including oil sands mining are becoming important in global energy supply due to decreasing reserves of conventional oil. For the Canadian oil sands, debate continues over the industry’s environmental impacts and capacity for export. The International Energy Agency has warned that expanding Canadian production hinges on transportation capacity[2]Hussain, Yadullah, (2014). Financial Post.

Environmental concerns regarding oil sands mining focus on the toxic waste byproduct of the extraction process and land disturbance. After the sand is brought to an extraction plant, it undertakes a dilution process in which it is mixed with hot water and chemicals so that it may flow freely into pipelines. The water that cannot be recycled is contained in tailings ponds, where the thick sediment emits toxins. Additionally, as with all mining, there are significant land disturbances.
