What is a common source of volatile organic compounds (VOCs) in drinking water?

Volatile organic compounds (VOCs) are a group of organic chemicals that can easily evaporate into the air. A common source of VOCs in drinking water is industrial processes. These processes can involve the use of solvents, cleaning agents, and other chemicals that may leach into groundwater or surface water supplies. Industries that manufacture or utilize VOCs can inadvertently contaminate nearby water resources through improper disposal practices, spills, or leakage from storage tanks.

While sources such as agricultural runoff can introduce other types of contaminants, the specific nature of VOCs makes them more prevalent in areas near industrial activities. Natural mineral deposits and forest vegetation generally do not contribute significantly to VOC levels in drinking water compared to industrial sources, which are more directly associated with VOC contamination.
