In nature, lakes and rivers contain carbon dioxide in concentrations smaller than 10 mg/L (or ppm), however, stagnant or contaminated water can contain higher concentrations because of organic decomposition. This creates a problem for fish farming applications.
Carbon dioxide is added to drinking water during the final phases of the purification process. In water softening processes carbon dioxide must be kept at a certain level in order to prevent corrosion.
