A laboratory study of the initial effects of dissolved carbon dioxide (CO2) on metal release from shallow sediments

Sequestration of carbon dioxide (CO2) into deep geologic reservoirs is a potential approach for controlling the rise of CO2 concentrations in the atmosphere. Proper characterization and permitting of storage sites is expected to include an assessment of the potential impacts of CO2 intrusion into overlying groundwater formations. In most natural settings, the dissolution of CO2 into groundwater will decrease the pH and can also release carbonate...
