- Dissolved gas
- Both abiotic and biologically facilitated reactions of contaminants with components of groundwater often produce species that exist in groundwater as dissolved gases. These gases are released into the air when the groundwater depressurizes under surface conditions. Examples: radon, carbon dioxide, methane, ethene, ethane, hydrogen, and acetylene.
