Sean Sterling, a registered Professional Engineer and Professional Geoscientist in Ontario, has over 20 years of specialized experience and expertise in hydrogeological characterization and investigation of fractured bedrock sites. Mr. Sterling’s experience has primarily focused on groundwater resource evaluation / source water protection, contaminant hydrogeology and remediation, and numerical groundwater modelling both in a research and consulting environment.

Mr. Sterling has been actively involved with surface water and groundwater source water protection work (water budgeting, municipal wellhead protection area studies, groundwater vulnerability assessments, etc) throughout Ontario since 2001, particularly in eastern and northern Ontario and acted as the lead hydrogeologist for Mississippi-Rideau Source Protection Region (MRSPR) from 2005-2008.

Recently, Mr. Sterling has acted as the Technical Lead for Drilling and Borehole Monitoring Systems as well as the Lead Supervisor for all field work and data collection associated with the Geoscientific Site Characterization Project (GSCP) of the deep Paleozoic sedimentary bedrock (~870 m below ground surface) at the Bruce Nuclear Power Development (BNPD) site. The focus of this project was to characterize the subsurface geology, hydrogeology, and geochemistry in support of an assessment to locate a Deep Geologic Repository (DGR) for low-level and intermediate-level radioactive waste at the Bruce site. This work is a 5 year study being completed for the Nuclear Waste Management Office (NWMO) with a budget of over $35M.

Mr. Sterling has managed numerous other large deep drilling programs (continuous coring) at fractured bedrock sites in both Canada and USA. Prior to consulting, Mr. Sterling worked as a Research Associate at the University of Waterloo focusing on the development of rock porewater characterization techniques, discrete level and multilevel monitoring systems in fractured bedrock environments and on the prevention of vertical borehole cross-connection in fractured rock systems by using temporary borehole sealing techniques.
