Dr Nicole Mikkelson

Director and Principal Geochemist

Nicole is a low temperature/pressure geochemist with >15 years’ experience in academic research and private consulting. She specialises in identifying and quantifying the mechanisms controlling the chemical composition of surface water, soil/regolith water (unsaturated) and groundwater. Her skills in the fields of geology, geochemistry, hydro-geochemistry, hydrogeology, and numerical modelling are engaged by clients in the mining, industrial and water resource sectors to assess causes and implications of impacts, and to inform environmental management decision making.

As a Principal Geochemist at Geochemical Scientific, she provides quantitative solutions to clients facing a range of environmental challenges including management of soils/regolith and groundwater impacts from anthropogenic sources of metals/metalloids and nutrients; acidic and neutral mine drainage risks; acid sulfate soils; seawater intrusion; dryland salinity, surface water-groundwater interactions and contamination of municipal and irrigation water supplies.

Nicole is regularly engaged to undertake implications/risk assessments that include application of standard and customised methods to characterise mine-waste materials, develop tailored sampling and analytical programs, and apply detailed data interpretative methods including predictive geochemical modelling. Nicole specialising in a range of environmental tracer applications to identify sources of contaminants, assess natural attenuation, identify groundwater recharge zones, assess mixing between different hydrogeologic units, understand surface-water groundwater interactions, investigate pit water – groundwater dynamics, and quantity groundwater “ages” and flow rates.

Nicole is a trusted advisor to clients on matters relating to environmental implications/risks and routinely assists during engagement with environmental regulators to negotiate terms/timeframes of investigation requirements, present findings of technical assessments and respond to regulator feedback.
