Landfill Aftercare and Remediation

The end of the working life of a landfill does not signal the end of its lifecycle, nor the end of the potential impact it may have upon the environment. EnviroWaste provides a full range of landfill aftercare services, ranging from soil and groundwater testing and remediation through to site rehabilitation and capping.

EnviroWaste routinely conducts monitoring work at both its own landfill facilities and contracted aftercare sites. Monitoring includes tests for:

• Groundwater
• Stormwater runoff
• Leachate collection
• Landfill gas migration
• Flare stack emissions

In addition to this, EnviroWaste has the capacity to deploy specialist staff and equipment for projects involving sampling and analysis at closed or uncontrolled waste disposal sites.

Rehabilitation of closed landfill sites is the final step in the lifecycle of a landfill. EnviroWaste has rehabilitated several landfill sites, such as the Devonport Landfill on the North Shore in Auckland. This site has been successfully converted into a park for the enjoyment of local residents and visitors to the area.
