Ground Gas Sampling

Waste disposal, past engineering or contamination can mean a variety of gases may be present in a large site so ground gas monitoring should be considered during any redevelopment or reassessment plan. Understanding the gas profile of a site will ensure safe development and legal compliance. Our ground gas services include:

• Testing for the presence and concentration of gases including methane, carbon dioxide, oxygen, carbon monoxide and hydrogen sulphide, as well as measuring the associated flow rate, relative borehole pressure, atmospheric pressure, and presence of any volatile organic compounds. Our testing equipment includes portable infrared gas analysers, photoionisation detectors and gasclam instrumentation.

• Ground gas sampling using vacuum boxes, vacuum cylinders, and passively and actively pumped sampling media.

• Gas spike surveys.

• Sampling dissolved gas in groundwater or bodies of water.

• FID building surveys.
