It is imperative to understand the potential effects of CO2seepage on the local environment. Accordingly, a flow through column system was designed and carried out to understand the potential impacts caused by CO2seepage, focusing on soil geochemistry changes. The main results of the laboratory experiments indicate that increased levels of CO2generate a quick drop in pH for both limestone sand and silica sand, and slightly increased ions concentration in solution phase. Once the seepage is stopped, a partial recovery for limestone sand towards the initial values of pH is recorded.
