フラッキングについて世間があまり知らない事

抜粋(デタラメ):

・フラッキングの技術それ自体は古く、1947年に遡る。現在、アメリカの油井の 90%はフラッキング技術を用いている。

It isn’t new.

Hydraulic fracturing has risen to prominence over the last five or six years, but the technique itself has been around a lot longer. The first hydraulic fracturing experiment was conducted in Kansas in 1947. It was not successful, but a patent on the process was granted in 1949 and the licensed user of the technique, Halliburton Oil Well Cementing Company, began commercial operations later that year. Since then about 90 percent of U.S. wells have been fracked.

・フラッキングで地下に圧入する物質の 99% 以上の成分は砂と水。

It mainly uses sand and water.

Environmental concerns about fracking center on the possibility of contamination by chemicals used in the process. This leads many people to believe that it is just a chemical cocktail that is being pumped into the ground. In fact, over 99 percent of what is pumped typically consists of sand and water. That doesn’t mean that contamination and environmental damage isn’t possible, but it may not be what you envisage.
