Jon Whittier has been characterizing complex hydrogeologic systems and modeling groundwater flow for over 12 years. He has developed models to design and manage wellfields, evaluate capture, simulate groundwater / surface water interactions, and evaluate impacts to environmentally sensitive areas. He has also designed and implemented models that predict the impacts to water resources both during and after the closure of open-pit mining operations.
One current focus area is modeling brine aquifers in Andean salars to support resource / reserve estimates for lithium and potassium under Canadian Securities Administrators National Instrument (NI) 43-101 and Australasian Joint Ore Reserves Committee (JORC) guidelines. These projects entail using density-dependent flow-and-transport models to simulate brine movement during extraction. Jon also supervises the development of conceptual and geologic block models. Another area of expertise is providing modeling support to evaluate the conceptual design of recharge and recovery facilities for the indirect potable reuse (IPR) of recycled water.
Jon is proficient in MODFLOW, MODFLOW-SURFACT, MODPATH, MT3D, and PEST.
