Selected Project Experience
Risk Assessment of seven closed landfills
This project included the installation of targeted groundwater monitoring bores and landfill gas bores and associated groundwater/gas monitoring to assess the likely risks associated with the former landfills. The risk assessment process resulted in a risk prioritisation of the former landfill sites and a program of work to address data gaps uncovered in the risk assessment process. Monitoring work is ongoing at many the closed sites.
Landfill Gas Investigations and Risk Assessment
Landfill “1”: Landserv carried out low cost, practical and focussed investigations to remove the buffer zone around an old landfill where encroachment occurred. The project involved targeted test pitting to characterise the waste and assess landfill gas generation potential. In addition, the scope of work included the installation and monitoring of perimeter landfill gas bores. The data collected from these activities was compiled alongside historical information to produce a conceptual site model and a landfill gas risk assessment with recommendations as to the removal or reduction (as appropriate) of the buffer. Furthermore, the investigation also provided the basis for satisfying the Ministerial Direction No. 1 issued by the Ministry of Planning for a number of rezoning decisions.
Peer Review (Various Development Applications) – Melbourne
Landserv has an ongoing engagement with a local Council to conduct peer reviews of landfill gas risk assessments submitted in support of planning applications. Landserv provides recommendations on whether permit conditions are satisfied and advises council planners accordingly.
Landfill Gas Investigation and Risk Assessment – Warrnambool
Landserv carried out investigations into a former landfill in an urban area. The investigations were staged to address the key risk issues in line with Council’s expectations and budgets. A series of landfill gas bores were installed, and a monitoring and risk assessment undertaken to ensure surrounding land uses are not at risk.
