Question

Pump jacks use upward force and pressure to slowly move oil up a drill shaft. which statement best describes an environmental consequence of this process? soil is created by the force and pressure of the drilling process. salt in the wastewater reduces soil fertility and vegetation growth. wastewater is contaminated with oil and becomes sludge in landfills. chemicals added to the fracking liquid can contaminate the groundwater.

Answer 1

Of the listed options, the best description of an environmental consequence from using pump jacks in oil extraction is that "chemicals added to the fracking liquid can contaminate the groundwater". This is due to the potential for substances in the fracking mixture to leach into groundwater sources if not properly managed, subsequently posing a risk to both local ecosystems and water quality.
