Landfill Gas and Vapour Risk Assessment
Potentially hazardous ground gases, either naturally occurring or from past site contamination, include methane, carbon dioxide, carbon monoxide, hydrogen sulphide, mercury, and various volatile organic compounds (VOCs).

Landfill Gas and Vapour Risk Assessment
Potentially hazardous ground gases may exist naturally, or be present as a consequence of contamination resulting from former use of the site. Typical potentially hazardous gases include methane, carbon dioxide, carbon monoxide, hydrogen sulphide, mercury and often a variety of volatile organic compounds (VOCs).
Historically, contaminated land assessment has focussed on the risks to human health and the environment from soil and groundwater contamination. More recently, there has been a number of high-profile ‘gassing’ sites resulting in a heightened awareness of the potential acute and chronic risks to human health from hazardous ground gases.
While there are a growing number of national and international guidelines related to this area, Core Environmental Projects believe that each site presents its own unique situation and certainly no development is the same. Therefore, whether it is a simple or complex site, we adopt a site-specific risk assessment approach underpinned by science, engineering, legislative requirements, best-practice and risk assessment principles.

Landfill Rehabilitation and Redevelopment
Core Environmental Projects were initially engaged to prepare a concept gas collection and interception design based on existing landfill gas investigations and risk assessments. Early in the review, Core identified several areas of opportunity where the landfill gas risks could be downgraded via detailed landfill gas investigation to support the completion of a quantitative landfill gas risk assessment.
