     Treatment should be carried out on prepared pads. However, due to site constraints it may be more
      practical to mix the lime insitu in 300 mm layers prior to excavation. This would require verification
      testing of the material before removal off site.

     Verification sampling and analysis is to be carried out on the treated soil to confirm that appropriate
      amounts of the neutralising agent have been incorporated into the soil at a rate of 1 sample per 50 m2 of
      natural material removed.

     Groundwater quality should be monitored through new groundwater monitoring wells located across the
      site.

     Management of groundwater seepage and rainfall collected in excavations and other works areas on
      site, including treatment recommendations, must be incorporated into the ASS MP.

     During construction, it is recommended that all waters collected from groundwater or surface water
      inflow, be retained, monitored and if needed, treated to comply with the appropriate discharge criteria
      prior to discharge offsite.
