Answer 1

Answer:

Option A, Chemicals added to the liquid can contaminate groundwater, this statement best describes an environmental consequence of this process.

Explanation:

• Fracking is a process of digging fossil energy sources, which need a lot of water and uses local water resources.
• It is drawn with high-pressure water, sand and elements, creating high pressure to block the porous rock and discharge gas.
• The  spill itself stops energy from the drilling position, and may even make earthquakes, mainly due to the pumping of overflowing wastewater into porous rock types such as limestone.
• The most significant result of water distortion is on groundwater.
