Contaminated soil or rock can act as a source of pollution for groundwater that directly flows through it. When an aquifer is contaminated with pollutants, it can pose serious health risks to humans and animals that depend on the groundwater for drinking or irrigation. Therefore, it is essential to clean the contaminated soil or rock in the aquifer to prevent further contamination of the groundwater and to safeguard the environment and public health. Groundwater remediation techniques such as pumping and treating contaminated water, soil vapor extraction, and bioremediation are commonly used to clean up contaminated aquifers.
