It’s vital that landfill site operators monitor emissions of gas from their sites to rectify any potential issues. Otherwise, they may breach permit conditions set by the Environment Agency (EA) and generate complaints from members of the public which may result in prosecution and hefty fines.
Environmental monitoring specialist enitial conducts detailed surface emissions mapping surveys of landfill sites to identify any sources of gas (usually methane) so that site owners can take corrective action.
Using topographical information about the site, enitial develops the scope of the survey area and the route of the field technician which is navigable via GPS on a PDA device. Its surface emissions specialists can be on site within a few days of the client’s initial contact to commence the survey after the necessary preparation work had been completed.
enitial’s technicians use the latest TDL500 Laser Diode Methane Detector to take readings from the site’s surface, gas and leachate collection system infrastructure as well as open tipping areas in the case of landfill sites. The
ATEX certified detector is extremely sensitive and can measure methane levels accurately to one part per million. The technician covers the site methodically along a grid provided by the PDA’s inbuilt GPS (typically a 10 metre grid) at certain intervals (usually three to four seconds). The figures are stored on an enidata PDA, a handheld based electronic data collection device and management system, developed by enitial to replace paper-based data recording and improve the efficiency of environmental monitoring.
Once the survey is completed, the data is exported, processed and plotted onto the site’s topographical survey to provide the client with visual representation of the methane concentrations across the site. Hot spots of gas and problem areas can be easily identified on the site survey and located accurately via GPS.
