Sequestering CO2 underground has its own set of environmental risks, including the potential migration of CO2
out of the storage reservoir and resulting acidification and release of
trace constituents in shallow groundwater. As part of a special issue
on carbon sequestration in Environmental Science & Technology, a
number of ESD scientists (including Charuleka Varadharajan, LianGe
Zheng, Marco Bianchi, Peter Nico, Nic Spycher, Yuxin Wu, Baptiste
Dafflon, Susan Hubbard, and Jens Birkholzer) participated in a study
(headed by former ESD scientist Rob Trautz) to investigate the potential
impact on groundwater that CO2 injection into geologic formations might have.
