Rate this item
(8 votes)

 What awareness do you have of coal seam gas mining and the related issues?

Significant concerns with Coal Seam Gas are the potential impacts that this industry will have on
•  water security
•  food production
• environment
• health

Water security concerns
• large amounts of water are used in the extraction of the gas
• waste water from the process contains large amounts of salt
• the artesian base may be contaminated by the process

Food production concerns
• mining is happening on good cropping soil
• the mining interrupts the use of farming land
• use of and impact of chemicals on the soil makes it unsuitable for farming
• degradation of and devaluation of farming properties
• eventual impact on Australia’s food production and valuable export industries of beef and wine

Environmental concerns
• gas leaks of methane into the environment increase carbon pollution
• chemical leakage contaminates the land
• chemicals used in the fracking process can cause contamination

 Health concerns
• reports from the USA identify many health issues in areas of high intensity coal seam gas production
• some local areas are already expressing health concerns (nose bleeds, headaches)
• mental health issues could result from the stress of loss of land and livelihood

The ABC has produced the most comprehensive map of Australia's coal seam gas activities to date: ( http://www.abc.net.au/news/specials/coal-seam-gas-by-the-numbers/)

Some of the main points made in this program:

Extraction: Coal seam gas, 98% methane, is extracted by drilling down to the coal seam
Average wells in Queensland are 600 metres in depth
The drilling may pass through the aquifers used for drinking water and irrigation

‘Fracking’: This process is sometimes used and involves water and chemicals being pumped into the coal seam, which creates a network of cracks in the coal, releasing the gas and water trapped inside

Water Content: One of the most contentious issues around coal seam gas is its thirst for water, and what impact this might have on the aquifers of the Great Artesian Basin and stream flows in the Murray Darling Basin.  Agricultural industries rely on underground water supplies in the Great Artesian Basin, which lies under some of the most productive farming areas in Australia.

As the water flows out of cracks in the coal, the gas trapped inside is released.  A mixture of water and gas flows to the surface, where the water and gas are separated and sent for processing.  The water is very salty and may contain toxic chemicals from the fracturing process, as well as those naturally present in the coal seam.

The National Water Commission estimates the use of 300 gigalitres of water each year.  This suggests that 31 million tonnes of salt will be produced over 30 years.

The Principle of Care for Creation

Coal seam gas extraction puts water availability and purity at risk.
All mining activities need to answer questions about environmental concerns.  One of the major issues with CSG is the use of large amounts of water.  Water is one of the most important resources of the planet.  It is also rich in religious symbolism.  We take care of water by ensuring both its preservation and its quality.

The Principle of the Common Good

At a reflection point in the grounds of Metta Karana Reflection Centre in Siem Reap, Cambodia, visitors are invited to draw water from a well.  When the bucket arrives at the surface, the water is pouring out of holes in the sides of the bucket.  A reflective process is then entered into about water belonging to all people, not just to those who own the well.  In many parts of the world, water is being viewed as a commodity to be sold, depriving those who depend on that water for their survival.  In Australia, The Great Artesian Basin is a resource that has been providing water for much of the drier parts of this continent since the first bore was struck in the late 19th century.  Risking contamination or severe reduction of the available aquifers leaves future generations deprived of this resource.

If much of the good cropping land is taken over by CSG mining, then the amount of food produced will be greatly reduced in a time of world food shortages.

The theme chosen for the Day: "Food Prices: From Crisis to Stability," invites us to reflect on the importance of the different factors that can give people and communities essential resources, beginning with agricultural work, which must not be considered as a secondary activity, but as the objective of every strategy of growth and integral development.  This is still more important if we keep in mind that the availability of foods is increasingly conditioned by the volatility of prices and sudden climatic changes.  We observe at the same time a continuous abandonment of rural areas with a global decline in agricultural production and, hence, in food reserves.  Moreover, spreading everywhere, unfortunately, is the idea that food is just one more merchandise and, hence, also subject to speculative movement.

Pope Benedict’s message for World Food Day 2011

The Principle of Participation

The principle of participation can refer to the need for all of earth’s creatures to participate in discussions involving harm to any creature.

In light of our broadened sense of the earth community, our call for participation must go beyond the demands of our human community to ensure that the rights of the natural world are also represented at the table.

The Principle of Accountability

This principle calls for all those involved in issues that may have ethical consequences to make a full disclosure of all information.  In the CSG debates, there is concern that the companies are not sufficiently up front with information regarding their use of chemicals and their thorough investigation into the environmental effects of their processes.  This principle also calls on those who are concerned about the effects of the process to keep pressure on the companies for full disclosure.

Possible Letter to Politicians

Dear Minister Burke

I am writing to you about the proliferation of the Coal Seam Gas Industry in Australia.

I have several concerns:
• the possible contamination of the Great Artesian Basin due to leakage of the chemicals used in the extraction process
• the possible contamination of soil through leakage of chemicals used in the extraction process
• good cropping land is being taken over by the coal seam gas industry when agriculture is such an important base for the Australian economy

There seem to be different rules for the use of water by farmers and the coal seam gas industry.  The strict controls on the use of water placed on Farmers do not seem to apply to those engaged in coal seam gas extraction processes.

I understand that legislation of this industry is a State matter.  However, because of the possible damage to our water and soil, there is a place for Federal intervention in this important issue.

I urge you to be proactive in preserving the integrity of our water and soil in the face of possible contamination that will affect our important farming industry.

Dear State Environment Minister / Local Councillors

I am writing to you about the proliferation of the Coal Seam Gas Industry in Australia.

We keep hearing about the wonderful benefits of this industry in terms of the economy.  However, I believe that there are other issues that must be considered in relation to this industry.

The main issue that needs to be addressed is the possibility of contamination of water and soil in the extraction process.

Our agricultural industry is of vital importance to our economy.  The increasing number of coal seam gas wells is already having an effect on our farmers with the increasing traffic on their properties, and roads and pipelines criss-crossing their properties.

I am asking you for assurance that you are doing everything in your power to safeguard the quantity and quality of our water and that you are supporting our agricultural industry as it faces a huge struggle against the might of mining companies.
