Notes:

  • Sampling was conducted at L8 and S7 only, with the ephemeral water course being dry again. The result for S7 and L8 are within the previously reported range for the site.
  • Notable levels of methane surface emissions at 2600ppm were detected at Waypoint ID W58 - located on top of the cap approx. 3m from edge closest to active landfilling area. Observation made above a crack recorded to be 1.5m long and 3cm wide. This crack has been resealed.
