What the title says, there's a 40 grams of CO2 and it's holding 840 kg of polluted water in place. And I don't even have a way to get rid of it since I can't send duplicants to "mop" the CO2.
High pressure liquids should force the obstructing gases away in similar manner how built tiles do.
Steps to Reproduce
Load attached save, check the flooded battery and gases/liquids around it.
