Our Services

Government regulatory and compliance

Geochemical Scientific assists clients in the mining, oil and gas and industrial sectors with the following regulatory compliance obligations:

  • Annual groundwater review and reporting (AGMRs)

  • Annual reviews of groundwater management plans (GMPs), seepage interception systems (SISs) and seepage management plans (SMPs)

  • Progressive Rehabilitation and Closure Plans (PRCPs)

  • Environmental Evaluation Notices (EENs)

  • Environmental Enforcement Order (EEO) – formerly Environmental Protection Orders (EPOs)

and more

Groundwater technical assessments

Geochemical Scientific offer water quality services relating to the following:

  • Conceptual models

  • Groundwater contaminant source and implications/risk investigations

  • Natural attenuation capacity assessments (qualitative and quantitative)

  • Groundwater “tracer” methods to: identify groundwater recharge zones; determine groundwater ages; and differentiate between mine and natural “contaminant” sources.

  • Derivation of site-specific trigger values (SSTVs)

and more

Acidic and/or Metalliferous Mine Drainage (AMD) assessments

  • Mine waste (rock, tailings, spoil) and sediment geochemical characterisation

  • Application of static and kinetic AMD characterisation approaches endorsed by regulators

  • Application of geochemical testing approaches (international academic methods) to further assess risks of AMD for PRCP or EA amendment applications.

  • Mine water quality assessments – seepage, recharge, pit water including hydrochemical profiling to assess stratification.

and more

Modelling

Geochemical Scientific offer specialised numerical modelling techniques to determine the following:

  • Geochemical Modelling

  • Numerical and Analytical Groundwater Flow and Solute Transport modelling

  • Numerical Reactive Transport Modelling (RTM) – coupled groundwater flow, solute transport and attenuation or mobilisation reactions

  • Numerical RTM modelling of vertical seepage and recharge of mine impacted waters

  • Numerical and analytical pit lake water quality modelling predictions (numerical)

and more
