Measuring and interpreting gas flow from landfill boreholes case study
Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the 'flow' ...

Flow measurement technology comparison: GA5000 Vs Hot Wire Anemometer
A typical landfill or contaminated land site under investigation will comprise of a suitable number of gas monitoring wells, with a planned series of monitoring visits. The monitoring will include gas flow measurements, which together with methane and carbon dioxide concentrations will be used to calculate gas screening values (GSV) and hence allow the determination of whether any gas protective ...

The latest ground Gas monitoring innovations
The latest Ground Gas monitoring innovations The traditional methodology for ground gas monitoring has been ‘spot monitoring’ – taking event readings at various set times to predict the sub surface gas regime on both on Brownfield and Landfill sites. This methodology is in general current practice under both the EU Landfill Directive 1999/31/EC which is supported by ...

Geotechnical Borehole Logging and Software
Geotechnical Borehole Logging Geotechnical borehole logging involves the use of boreholes to perform investigations on materials from deep underground for geotechnical designs. The approach is applied for obtaining information on ground movements, groundwater levels, material strengths, permeability, and pore pressures. Geotechnical borehole logging is a cost-effective and time-saving technique. ...

Reaching underground resources
Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

Multilevel Groundwater Assessment of Confining Unit in a Bedrock Sequence near Sarnia, Ontario
Untitled Document INTRODUCTION Two sites in southern Ontario were studied through instrumentation of boreholes with Waterloo Multilevel Monitoring Systems. These sites are located approximately 7 km (4.3 miles) apart and lie between Sarnia to the northwest, and Petrolia to the east in lambton County, Ontario, Canada (figure 1). Multilevel monitoring devices were installed to ...
