What is aquifer contamination?

Aquifer contamination refers specifically to the situation where pollutants, which can be various harmful substances such as chemicals, heavy metals, or pathogens, infiltrate and compromise groundwater supplies. This process can occur through various routes, such as industrial discharges, agricultural runoff, or even leaking septic systems. When contaminants enter an aquifer, they can adversely affect the quality of the water, making it unsafe for drinking, irrigation, or other uses. Monitoring and preventing such contamination is crucial for protecting water resources and ensuring safe drinking water for communities.

Climate change's impact on groundwater temperatures, the cleaning techniques for polluted sources, and the collection of surface water do not specifically define aquifer contamination. These options address related but distinct issues in water resource management.
