In memory: Mr. Leslie Strachan

Memorial Service: Council for Geoscience Auditorium, Friday 4 October 2013, 13:00 onwards

Mr. Leslie Strachan, born 16 October 1959, has worked for the past 24 years in the water sector focusing on hydrogeological mapping, groundwater-based rural water supply projects, and research relating to mine water contamination and its management. At time of his death, he was employed as Senior Geohydrologist of the Water Geoscience Unit at the Council for Geoscience, where he is responsible for research relating to mine water management leading to the development of mine water management strategies and regional mine closure in Witwatersrand gold mines (both operational and non-operational), mine water rebound predictive modelling, pollution source and liability apportionment using geochemical modelling and chemometrics, and remediation of contaminated groundwater. Leslie has worked on a number of regional consultancies in several SADC countries in both the mining and groundwater water field. Previously, he was a founding member of the consultancy company Hydro Aqua Earth cc, involved in groundwater, mine water management, and environmental consultancy, after a prior period of employment at the Council for Geoscience, where he worked initially as a senior researcher and later as business unit manager where he was responsible for the development and management of the unit, coordination and management of research and consultancy projects as well as development of capacity. Earlier in his career, Leslie was the Technical Director Groundwater Services (Pty) Ltd., whose core business was groundwater source characterization, optimal borehole siting, drilling and groundwater-based water supply systems installation and monitoring. Before his employment at Groundwater Services (Pty) Ltd., he was a hydrogeologist with the Geological Survey and Mines Department of Swaziland, focusing on comprehensive and detailed hydrogeological mapping.

Leslie completed his undergraduate and honours training at the University of Reading (United Kingdom), whereupon he was involved in coal exploration activities in Swaziland. He thereafter embarked upon a B.Sc. degree in Mining Engineering at the Pennsylvania State University (United States of America). Leslie has worked on several research projects dealing with groundwater exploration, environmental management, mine water management, mine closure issues, and pollution issues. He has also worked extensively on groundwater assessments and assessments of sustainability of groundwater-based water supply schemes in rural South Africa.
