What can be done to mitigate the potential drastic effects? Whether a landowner, developer or regulator, the objective is the same: to ensure that any existing or proposed development remains or takes place safely.

Due to unexpected temporary weather conditions and seasonal effects on ground gas migration, monitoring has to be undertaken over a potentially wide geographic area, lasting several months. Sampling techniques like soil probes require detailed laboratory analysis using thermal desorption and gas chromatography, and are labor-intensive and costly.

However, there is the possibility to undertake long-term, un-manned, continuous, monitoring using specially designed borehole devices that are battery-powered, record multiple gases and make the data accessible for download for later analysis. 

The GasClam 2 collects unmanned continuous ground gas concentration data as well as parameters that are known to control it, such as subsurface pressure, atmospheric pressure and water level. This device reduces uncertainty by providing the full picture of what is happening below ground. By observing the process of controlling the ground gas regime, workers can predict how it will change in the future.

Using the GasClam 2 provides financial benefits as well. Implementing this instrument to your detection methods reduces the number of site visits by a field engineer. It also reduces the overall length of monitoring programs as it allows for legislative data requirements to be met quicker. Lastly, this device is designed appropriately, rather than over-engineered, to offer solutions based on complete and robust data.

Applications that can benefit and utilize the device are, but not limited to:

  • Brownfield site investigation
  • Landfill perimeter monitoring and control
  • Shale and coal bed methane/seam gas site monitoring
  • Vapor intrusion studies
  • Waste management
  • Refineries and petroleum storage monitoring
