I have been a consulting hydrogeologist for 10 years, with my primary experience being in the mining environment throughout Africa. I have work experience within the South African environment, as well as in countries such as DRC, Mali, Madagascar, Zambia, Tanzania and Botswana.
I have been working as a numerical modeller for the past 8 years, focussing on the development and execution of contaminant transport and groundwater flow models using MODFLOW, as well as FeFlow in some instances.
My key strengths are my leadership and technical skills, as well as my passion for hydrogeology.

I am a senior hydrogeologist at GEOSS South Africa with a BSc Honours through Stellenbosch University and an MSc in Geohydrology from Free State University. I joined GEOSS as a full-time employee at the end of 2015 where I have worked since, predominantly on groundwater exploration and development projects for the agricultural, industrial and municipal sectors. Notable projects include borehole drilling, testing and production management for the towns of Calvinia, Brandvlei, Makana/Grahamstown, Paarl and Wellington in South Africa. My main work responsibilities revolve around the test pumping of boreholes for the purposes of aquifer parameter estimation and production recommendations. I have been involved in MAR projects and in 2019 attended the IAH MAR Training Workshop in South Africa, ISMAR 10 Symposium in Madrid, Spain, and more recently ISMAR 11 in California, USA. My international work experience includes Sierra Leone and Botswana, which consisted of on-site drilling supervision and management, as well as injection testing for MAR.

With over 30 years of experience, I have worked in mining and exploration, groundwater consulting and mine de-watering. I have completed many geological projects, including gold and platinum exploration and was fortunate to be involved with the initial exploration and start-up of the ultra-deep Northam Platinum mine and the low grade/high tonnage Tarkwa Open-cast mine. Here I led a >$1 million / year diamond drilling programme at what is now a world class operation.

My groundwater consulting has exposed me to a broad spectrum of projects, including exploration and feasibility studies, developing water for urban municipalities and rural communities, developing sanitation/WASH protocols, compiling impact assessments for EIA's, assessing water quality and contamination investigations, monitoring and audits for environmental compliance and undertaking drought relief interventions etc.

Typically, my clients have included municipalities, government departments, NGO's, property developers, organised agriculture, manufacturing and industry, waste disposal contractors, renewable energy utilities and bottled water plants etc
