The GAC treatment system will be expanded to allow all three well to operate simultaneously.

Two GAC vessels will be added to the westerly site (11505 Pioneer) so that well 3 will have its own GAC treatment with lad/lag configuration. Additionally, a permanent chemical building will be added to each site, and the hyropneumatic tank will be removed from the easterly site. The current chemical building at each site will be removed.
