The oil and gas industry and trade groups are quick to point out that chemicals typically make up just 0.5 and 2.0% of the total volume of the fracturing fluid. When millions of gallons of water are being used, however, the amount of chemicals per fracking operation is very large.
How deep can an ocean get? Real Deep ;) Actually, it can get to 35,838 feet. That's how deep Challenger Deep in the Marianas Trench off the Marianas Island in the Pacific Ocean gets. The U.S. Navy su â¦ bmersible Trieste reached it in 1960. That's about a mile deeper than Mount Everest is high. And that's real deep.
Its average depth is about 3,688 meters (12,100 ft), and its maximum depth is 10,994 meters (6.831 mi) at the Mariana Trench. Nearly half of the world's marine waters are over 3,000 meters (9,800 ft) deep. The vast expanses of deep ocean (anything below 200 meters or 660 feet) cover about 66% of Earth's surface.
