CO2 Sequestration – What could go wrong?

Risks to underground drinking water from improperly managed carbon dioxide sequestration projects can include CO2 migration into the water table, causing
leaching and mobilization of contaminants (such as arsenic, lead and salt), the EPA said. Lawrence Berkeley National Laboratory is evaluating the potential for leakage of sequestered CO2 to mobilize trace elements of contaminants such as arsenic, barium, cadmium, mercury, lead, antimony, selenium, zinc, and uranium.

Carbon dioxide has been tried on a large scale at four sites, the agency said: at Sleipner in the North Sea, at In Salah in Algeria, at Snohvit in Norway, and in the Weyburn Field in Alberta, Canada. There have been no documented cases of leakage from these projects, the EPA said.

Wow! 4 Pilots less than 5 years old worldwide. I feel better that this will be required, since the science is settled.
