What is the impact of fracking on water systems?

Fracking, or hydraulic fracturing, is a method used to extract natural gas and oil from deep underground. One of the significant concerns associated with this process is its potential to introduce pollutants into water systems.

During fracking, high-pressure fluids are injected into the ground to fracture rock formations, releasing natural gas. This process can result in the leaching of harmful substances such as methane, heavy metals, and various chemicals used in the fracking fluid into nearby groundwater supplies. Additionally, if proper safeguards are not in place, spills and leaks can occur at the surface, further contaminating local water resources. The potential for these pollutants to reach drinking water sources poses significant risks to both human health and the environment.

Understanding this impact emphasizes the need for careful regulation and monitoring of fracking activities to ensure water safety. Thus, the correct answer highlights a critical aspect of fracking's environmental impact—its ability to compromise water quality through contamination.
