“[F]ive issues can be identified that raise concerns about the impact of fracking on health. Firstly, the process of fracking uses a wide variety of chemicals, including friction reducers, surfactants, gelling agents, scale inhibitors, acids, corrosion inhibitors, antibacterial agents and clay stabilisers. Additional naturally occurring heavy metals and radioactive materials may also be mobilised from the rock during its fracture, including arsenic, cadmium, chromium, thorium and uranium and these may also interact with the chemicals in the fluid.
In addition, the possibility of accidental release of chemicals and gases through fire, vandalism, or spills and leaks from poor practices is an ongoing risk.
Toxic mud and fluid by-products from the drilling and fracking, as well as spills of oil and gas wastes, are not uncommon. The health impact of such chemicals depends on factors such as the toxicity, dose, route and duration of exposure, and the vulnerability of the people being affected…
Secondly, air may also be contaminated by volatile chemicals released during drilling (combustion from machinery and transport) and from other operations, during methane separation or by evaporation from holding ponds. Methane gas is also explosive….
Thirdly, fracking requires substantial amounts of water, 1.5 million gallons per well … A shortage of water would pose considerable threats to health and well-being of people living in the area. The company proposes using some of the waste water for fracking. However, this will very possibly involve the burning off some of the toxic residues leading to additional air pollution, as well as storage difficulties.
Fourthly, the soil may be contaminated by drilling sludge, which may contain drilling mud, hydrocarbons, radioactive material and heavy metals. This would have serious consequences for grasslands used for leisure or agriculture purposes. The consumption of meat and or milk from animals grazing on such land would also give rise for concern.
Finally, the British Geological Survey states that it is well established that fluid injections can cause small earthquakes and fracking has been associated with two small quakes near Blackpool.
It is widely recognised that we need to reduce our emissions of greenhouse gasses. The adoption of fracking is a step away from a solution to the problem of climate change. We must leave any remnants of fossil fuel in the ground, instead of seeking ever more expensive and environmentally destructive methods of extracting them. … In the interests of public health, we must not allow fracking in Ireland.
Any tragedy is upsetting; an avoidable tragedy is all the more so.”
