Disadvantages Of Fracking Flashcards
(35 cards)
What are the 6 main focus disadvantages of fracking?
Water contamination Water usage Seismic hazards Noise pollution Landscape damage Climate Change
What are 3 ways of fracking causing water contamination?
1) Percolation form surface
2) leakage through pipe
3) spreading through fissures
Around what percentage of the fracking fluid is contained underground?
50%-70%
Despite Quadrilla and other groups in favour of fracking saying the water will be treated as a plant what is the argument to undermine this?
Some chemicals are untreatable and undetectable by certain plants. Due to the chemicals being closed off they are unable to adapt the plants
What fraction does the UK get it domestic water supply from the groundwater aquifers?
3/4
How much of the UK water supply comes from our own resources?
38%
What are the regulations and attempts to manage the possible water contamination threat that Quadrilla as stated it will perform?
Impermeable surface membrane to prevent percolation, three layers of casing around drill and pipe, monitoring the fissures and the site 2 years after completion
What are three damaging chemicals that are put in the fracking mixture?
Benzene, hydrochloric acid, menthol
What are some of the chemicals that can come from the underground shale rock and cause water contamination?
Radon gas and Methane
How many chemicals can be injected into the fracking fluid?
700
What is the increase in me being present in areas near to fracking sites compared to those that are not?
17X Higher
What can some of the chemicals in the open pits pose in terms of air pollution?
Ground level ozone and acid rain
How much water do possible fracking sites use for each frack job?
8 to 20,000,000 L of fresh water
How many gallons of water used in the US for fracking every year?
72,000,000,000,000 gallons
Why does the water fracking fluid have to be freshwater?
Because seawater has a higher salinity that can react with the chemicals in the fracking fluid to make it less efficient and more dangerous. Seawater is also impractical to use as most of the fracking sites are further away from the sea
What do those in favour of fracking point towards in terms of counteracting the argument that fracking uses a lot of water?
Underground coal, oil and uranium mining uses around 2.5 times to 13 times the amount of water that fracking sites use
How many faults are there in Lancashire and name a notable example?
50 including the Pennines Fault
What methods do Cuadrilla state that they will use to limits the impacts of seismic hazards?
Traffic light system & monitoring development of faults
What other form of energy production produces considerable earthquakes yet there is no concern as large as there is for fracking?
Nuclear power
What arguments do Cuadrilla and the DECC state in terms of the severity of the possible seismic hazards?
Vibrations caused by trains and trucks cause greater magnitudes and the U.K does not sit on geology of which is as active and extreme as the US
What is the population density per kilometre squared for the UK and US?
UK equals 267/KM2
US equals 36/KM2
Where could some of the possible noise pollution from fracking so come from?
Trucks travelling to and from the fracking site, the drilling process
What might the increased noise pollution in the area near to fracking site cause?
1) Disturbances to the landscape
2) decreased quality of life
3) decreased housing prices
4) emigration away from the rural area
What are Cuadrilla and the government trying to provide in order to mitigate the effects of a close proximity fracking site?
Royalties that consist of a £100,000 grant to the local area and 1% of the revenues. The company has Ineos has furthered this to 6%
