Environmental Sciences & Management - Baseline Geohydrological Investigations
Specialist geohydrological 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.
› 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
