Monitoring

 

As a company we employ specialised field technicians for Gas and Groundwater Monitoring at investigation sites. We are also pleased to offer gas and groundwater monitoring as a standalone service for use by external clients for their own projects.

Gas and Groundwater Monitoring 

We utilise a combination of monitoring equipment in order to obtain the most accurate readings possible. A Geotechnical Instruments GA2000 Infra Red Gas Analyser is used to provide measurement of methane, carbon dioxide, carbon monoxide, hydrogen sulphide, oxygen and atmospheric pressure and a Gas Data GF60 flow meter is used to measure gas flow ranges.

These instruments can be used in conjunction with our other monitoring equipment which includes a hand held Photo Ionisation Detector (PID) (calibrated to isobutylene), free product interface meter in-situ water testing kit (capable of testing dissovled oxygen, conductivity, redox potential, temperature and pH).

Gas and Groundwater Sampling 

Both gas and groundwater sampling services are also available, with methods of obtaining water ranging from mini down hole pumps to inertial pumping systems (waterra) or bailed sampling. A discrete sampling method, to obtain samples from specific depths within the installation is also available.

Gas and groundwater sampling can be conducted during any phase of the monitoring visit, either pre or post purge. Gas samples are commonly obtained in both Gresham Tubes and Tedlar bags. If the projects monitoring specification requires, wells can be developed by our technicians to ensure that samples obtained are representative of the entire site regime rather than localised areas.

Clients are able to create bespoke monitoring and sampling solutions to enable site specific data and sample collection.
 
In addition to gas and water monitoring we can arrange for on site earthworks monitoring and testing.
