Monitoring includes well head measurements, valve adjustments and can occur at a frequency that meets the needs or conditions of the system and other site sensitivities. Monitoring typically includes taking the measurements of gas concentrations (methane, oxygen, carbon dioxide/nitrogen, carbon monoxide), vacuum/pressure levels, gas flows and temperature. Water levels are also obtained in gas extraction wells at regular intervals.
Ground surface emission monitoring over the landfill is sometimes conducted to take measure of gas emissions through the landfill cover. Such activities can help assess the effectiveness of active gas collection efforts at a site.
We have developed a proprietary web-based data logging system that provides connection to a dedicated server where all operating data is added to a database. Operating information is relayed to the secure server, where various calculations, data integrations and summaries are performed. This proprietary system has been developed over a number of years in an effort to facilitate emissions credit verification and regulatory environmental monitoring reporting requirements.
