Geochemical Analysis

Geochemical Analysis

Geochemical modeling to predict the behavior (fate and mobility) of contaminants in groundwater, including:

Source term definitions
Pit lake models
Block Cave discharge predictive models
Solute transport models to evaluate liner requirements for tailings and waste rock disposal
Third party evaluations of models prepared by others
Kinetic based dissolution/precipitation models including transport

 

Geochemical Fingerprint analysis to define sources or distinct waters or other forensic applications using:

Major ion characteristics
Trace metals
Stable isotope ratio analysis

 

Mine permitting issues involving:

Acid Base Accounting
Evaluation of leach testing results
Humidity cell tests
Closure issues

 

ss
ss2

Design and implementation of client specific testing plans: 

Sequential Batch Tests
Barrel and larger scale tests
Field programs
Specialized laboratory testing
To estimate sorption parameters
To evaluate reactions paths
To evaluate specialized treatment options

 

Geochemical training through short courses and client requested seminars

Statistical and geostatistical analysis of chemical data sets

Expertise in the behavior of specific metals and contaminants in groundwater including:

Arsenic
Uranium
Barium
Copper
Sulfate
Cyanide
Chromium
Nickel
Lead
Fuels and fuel fingerprinting
Fate and mobility of organic compounds

 

Geochemical Modeling using PHREEQC, MINTEQA2, Geochemist’s Workbench, EQ3NR/EQ6, WPHAST, HYDRA/MEDUSA, and EnviroInsite.
