Excavation of the third well in downtown Wheatley (APEC 3) has been completed and a temporary venting system installed. Air samples taken from that site have been collected for laboratory analysis.
The next phase in the process will be to place cameras in all three of the wells with the aim of learning more about the construction and depth of the wells.
That process is expected to take place by January 28.
Homeowner access continues in between any investigatory work.
