Abstract
The system delivers liquid CO2 125 into the casing screened interval of an eductor pipe 110 within a water well. The eductor pipe 110 assembly extends from the top of the well (or land surface) to the top of a disk interval isolation assembly 123. The disk assembly isolates a predetermined length of screened interval, so liquid CO2 125 can be injected and contained within the interval and immediately outside the casing.
