Tag: Caffeine in water

According to a study published by the National Institutes of Health, caffeine has been detected in surface and groundwater systems due to human waste. So, is there caffeine in water that comes from your tap or is it only in specialty products? The simple answer is that naturally, no, but human activity can introduce trace amounts, and certain commercial waters are explicitly caffeinated.

According to a 2022 global study, caffeine was detected in over 50% of 1,052 river sampling sites, highlighting its widespread presence as a pollutant. This raises a critical question: is caffeine found in water? While it doesn't belong there naturally, human consumption patterns ensure trace amounts can enter and remain in the water supply.
