To release methane from coal seams the groundwater trapping the gas must be continually pumped out. The water contains a cocktail of chemicals including carcinogenic hydrocarbons such as benzene, toluene, ethyl-benzene and heavy metals such as arsenic, cadmium, mercury and lead. Coal bed methane wells are hydraulically fractured to increase the flow of water and gas.

Millions of litres of produced water has to be disposed of from each well. Over time this represents a massive volume of water and toxic material released into rivers, estuaries and the sea. In most cases the industry claims that the water does not require treatment or detailed monitoring. Which is not true.

Continuous removal of water from coal seams depletes ground water and may eventually lower farmers boreholes and surface water flows (streams and rivers). It can also change the flow of groundwater drawing fresh water into the coal seams. Lowering the water table has allowed methane and other gases to be released into streams and aquifers in other countries.

Large quantities of methane, hydrogen sulphide, nitrogen oxides (Nox) and other pollutants are emitted from site equipment, diesel generators and trucks. Noise pollution and further emissions of methane and airborne pollutants occur as the gas is processed and pressurised in sprawling temporary infrastructure. Flare stacks burn off unwanted gasses and cause noise and light pollution and more toxic emissions.

Methane Migration into Aquifers

The Coal Bed Methane (CBM) process along with hydraulic fracturing releases methane from coal seams. The gas wells themselves are the most common pathway for methane migration (leakage) but once released, methane can also migrate through the overlying geology. This can lead to high levels of methane in streams, aquifers and eventually drinking water. Methane is 100x dangerous than carbon dioxide as a greenhouse gas.

Leaking wellss are a huge problem.

6% of gas wells leak immediately and 50% of all gas wells leak within 15 years. Exploration requires thousands of wells to be drilled. These wells can never be removed or recycled, the steel and concrete structures plunged deep into the geology decay slowly over time. All gas wells will leak eventually.

Dangerous Work Environments

The jobs created by the fracking industry are small in number for the size of the investment. Local job creation is short term, unskilled and in high risk areas/occupations. These workers are at increased risk of industrial disease and accidents. Exposure to chemicals and produced water creates acute health risks for workers.

The result of this type of dispersed industrial development on the countryside is catastrophic. Wildlife corridors are disrupted. Edge effects created by the cutting up of habitats into smaller and smaller pieces threaten biodiversity and the release and distribution of toxic compounds adds to the cumulative impact.

If this industry is allowed to get in, then number of communities under threat will increases massively. The impacts and dangers are acute and borne by local communities who find themselves living in gasfields. The rewards go to an elite of shareholders, directors and investors. Stopping this industry in India will send a clear message to other countries that the impacts and dangers are unacceptable.

Pipelines, Compressor Stations & Flaring are needed. A sprawling temporary gas infrastructure is needed to connect thousands of sites across the landscape. The pipelines used for transporting gas and waste create the additional danger of leaks and explosions. Pipeline construction cuts scars across the countryside and blights surrounding areas with planning restrictions. Flare stacks burn off unwanted gasses on every site and cause noise/light pollution and toxic emissions. Noise pollution and further emissions of methane and airborne pollutants occur as the gas is processed and pressurised.

Many wells require many sites which in turn require access roads, foundations, floodlights, CCTV and enclosures. This pattern of development divides countryside, threatens rights of way ,damages and slowly destroys the natural beauty and diversity of an area.

Damage to Existing industries is eminent.

Farming and food production, recreation and tourism suffer at all stages of coal bed methane exploration, appraisal and production. An areas reputation and land base are exposed to long term dangers that exist even long after the industry has gone.

Removing liquid and solid waste requires many tanker/truck movements for each site . This is in addition to construction vehicles and drilling and fracking equipment when the site is commissioned. Because the lifetime of each well is short (2-5 years) this armada of heavy vehicles will roll across the countryside.

Road damage is an inevitable consequence of methane exploration due to intensive transportation of materials and machinery. Subsidence and earthquakes may be caused by the process and are quite common in conventional coal mining. The cost of the road damage caused by fracking traffic will surpass the tax revenues generated by them

Home owners in the extraction areas can find themselves trapped in a house they can not sell, re-mortgage, insure or develop. An area already suffering from a decline in existing industries is further impacted by industrialisation (sites & pipelines), air and water pollution and the resultant health impacts.

Methane will not replace other fossil fuels, it will be burned in addition to the oil, coal and gas that has already been discovered. By developing these new energy extraction techniques we are expanding global reserves of hydrocarbons and increasing emissions. The chemistry of the atmosphere is changing and due to drought, flood and starvation the global death toll already stands at 450,000 annually.
