Injecting CO 2 into deep geological formations can be an effective carbon removal and storage technology to mitigate global climate change. Interaction of injected CO 2 with rock formations changes pH and hydrochemistry within the deep injection zone (> 800 m depth). However, cap rocks and multip...
