  • Landfill gas H2S increase measured with high-range analysers

    Hydrogen sulphide levels (H2S) in landfill gas have increased and Geotech has responded to changes reported by landfill site operators by now offering analysers measuring H2S up to 10,000 ppm. Rapidly rising H2S levels are thought to be caused by waste-to-landfill content changing largely as a result of success in recycling and other initiatives to avoid sending waste to landfill. Previously, H2S ...

  • The latest technology in landfill gas analysis

    Part II A of the Environmental Protection Act 1990 sets the minimum standard for contamination when land is redeveloped - as a minimum, sites must not qualify as contaminated land once they have been developed. The utilisation of brownfield sites therefore necessitates environmental investigation work, but Matthew Penfold from Geotechnical and Environmental Assessment Associates (GEA) says ...
