I saw that documentary too[1]. They will see this discovery not as 70 years of clean drinking water, but as 70 years of huge profits. They will do whatever it takes to buy exclusive rights and then pump it out as fast as they can (with little care for the environment), put it in bottles, then cleverly market and sell it to the local people who live there, for prizes that only the middle and upper classes can afford.
They make billions that way. Sickening.
Let's hope the government there will do good and keep multinationals like Nestle from ripping this water off the local people.
