Carbon Dioxide
Carbon dioxide is a gas that dissolves in water from air and underground sources. It can make water slightly acidic but is not harmful at typical levels in drinking water.
Carbon dioxide naturally enters water from the air and underground sources like decomposing organic matter and volcanic activity. It readily dissolves, forming carbonic acid which slightly lowers water pH. While not typically a health concern in drinking water, high levels can affect taste and potentially corrode plumbing. Water treatment plants monitor CO2 indirectly through pH testing and may adjust acidity if needed. The presence of CO2 in water is a normal part of the natural carbon cycle.
