Highly experienced in various aspects of hydrogeology, including contaminant hydrogeology (detailed assessment, fate and transport, risk assessment, modelling, remediation), visualisation of hydrogeological data, isotopic hydrogeology (tracers, aging), hydraulic containment modelling for waste management (eg. phytocovers, liner systems), hydrogeological assessments for landfills, groundwater inflows to excavations and other subsurface structures, groundwater flow and transport modelling, groundwater resource mapping and vulnerability assessment. My client base covers a broad spectrum of public and private sectors and activities, with a wide range of issues requiring simple to complex solutions.A particular interest of mine involves the application of horizontal wells for groundwater remediation purposes (which started at the Nyrstar Hobart Zinc Smelter), where I designed and implemented a groundwater interception system consisting of 13 horizontal wells drilled underneath the Smelter plant. Since 2009, the system has prevented the discharge to the Derwent River of approx. 120 tonne/year zinc, 5 tonne/year cadmium and 0.5 tonne/year copper (among other contaminants), and won the Consult Australia Silver Award (Environment) in 2010. I also designed and implemented the first horizontal leachate extraction well in Australia to be retrofitted to a landfill for leachate seepage control. In the right circumstances, horizontal wells can offer a cost-effective alternate solution to difficult-to-reach contamination issues.
