Specialist hydrogeological and geochemical investigations are carried out on greenfields sites, predominantly as a specialist study for the authorisations undertaken by the Environmental Management team, as well as for other consultants within the environmental management field.

Specific services include:

• Field work investigation
  › Geophysics: gravity, resistivity, electromagnetics, magnetics, radar
  › Soil / waste sampling and analysis: including Waste Classification, XRD, XRF, acid base  accounting etc.
  › Hydrocensus; identifying groundwater users and collecting borehole data.
  › Borehole drilling: percussion / mud rotary / odex / diamond drilling
  › Pump testing to determine aquifer parameters

• Sampling and analysis
  › Inorganic, organic, trace elements, radioactivity, stable isotopes, biological and toxicity.

• Modelling
  › Conceptual models
  › Flow modelling (including impacts associated with mine dewatering / post-closure filling)
  › Geochemical modelling
  › Mass transport modelling
  › Modelling of the effectiveness of mitigation measures

• Mitigation measures
  › Source removal or isolation
  › Cut-off systems / Dewatering and treatment
  › Waste stabilisation
  › Natural attenuation

• Design and implementation of mitigation measures
  
• Monitoring of the effectiveness of mitigation measures
