Hydrogeological Assessment, December 2017

• Landfill is not impacting on offsite groundwater beneficial uses and hence complies with BPEM and the site licence.

• Leachate management is required to reduce leachate levels down to compliance level. These works have gone out to tender.

• With the removal of leachate and exposure of the well perforations, it is anticipated that landfill gas production will increase marginally.

• The most recent groundwater chemistry results indicate leachate is not impacting on groundwater.
