News and Events
Dick Jackson published an opinion piece in GeoStrata, the journal of the Geo-Institute of the American Society of Civil Engineers. This journal provides technical discussions and topical issues to the geotechnical and geoenvironmental members of the ASCE. The article – obtainable from Geofirma – is entitled “Civil Engineering Educators Must Teach Applied Geology to Their Students”.
It discusses the need to re-think the way that civil engineers are taught the applied earth sciences in university – if indeed they are taught such critical information. As was observed as long ago as 1981 in an ASCE journal a “large proportion of civil engineering graduates have had none, or only minimal, exposure to applied geology in our universities.” This situation is somewhat better in Canada than the USA, but not markedly so. How is this possible when we are building ever-longer tunnels within complex stress regimes in rock masses, deep geological repositories for nuclear waste, pipelines and highways for routes crossing active faults and terrain with evidence of landslides and rockfalls?
The applied earth science behind such engineering practice is discussed in some detail in Dick Jackson’s new textbook published this month by Cambridge University Press and to be released in North America in March. It is titled: Earth Science for Civil and Environmental Engineers.
Ken Raven co-authored on a recent paper published in the Canadian Journal of Earth Sciences concerning the origin and Rb-Sr age dating of porewaters in low-permeability Ordovician sedimentary rocks at the Bruce Nuclear Site, Tiverton Ontario.
Geofirma Engineering was recently awarded a 5 year contract by the Nuclear Waste Management Organization (NWMO) to assist the NWMO in evaluating the performance of proposed Deep Geologic Repositories (DGRs) for the safe long term disposal of used nuclear fuel. The NWMO program is now in a site selection phase with several potential sites for hosting a DGR in in crystalline rock in Northern Ontario and sedimentary formations in Southern Ontario. Site characterization activities are underway and have advanced to initial borehole drilling and testing. Geofirma will be creating detailed numeric models that integrate geoscience data with repository designs to assess the long term repository performance (over 1 million years). The transport of radionuclides in groundwater to potential impact points such as water supply wells and surface water will be simulated for a number of scenarios. Geofirma will also perform gas transport modelling of corrosion products to assess both gaseous radionuclide concentrations and potential repository pressurization. Geofirma was selected to perform this work based on our more than 15 years experience in modelling DGR performance for hypothetical repository settings and designs. Geofirma also completed similar assessments to support the ongoing licensing process for the proposed Ontario Power Generation (OPG) DGR for Low and Intermediate Level Radioactive Waste at the Bruce Nuclear Power site.
Nicola Calder presented at the TOUGH2 Symposium in San Francisco October 8-10. The first presentation is a poster, “ Concurrent Simulation Of Linked Models At Multiple Scales Of Repository Gas Generation And Transport”, based on work conducted with John Avis for the NWMO. The poster and associated paper discusses modifications to T2GGM (a TOUGH2 variant developed by Geofirma and their partner Quintessa) to link the boundary conditions of separate models to be solved concurrently and the application of this approach to modelling repository scale gas generation and transport in a deep geologic repository for high-level radioactive waste in a Canadian sedimentary rock setting. Secondly, Nicola presented an oral presentation for Robert Walsh, entitled “A Numerical Study of Barometric Loading in Groundwater Monitoring Wells using TOUGH2”. This talk presents work conducted by Robert Walsh with Nicola Calder and Nicholas Sgro to clarify the physics involved in barometric loading effects on water levels in groundwater monitoring wells.
Robert Walsh will be attending the 27th World Gas Conference (WGC 2018) in Washington DC from June 25-29. Along with his co-presenter Steve Pardy from Union Gas, he is presenting a talk and paper entitled “Expanding Capacity in Ontario’s Storage Pools.” This work describes the qualitative and quantitative techniques employed to better understand risk in natural gas storage applications, and outlines the systematic approach used to demonstrate that the maximum pressure could safely be increased beyond historical levels. We hope to see you there.
Dick Jackson was appointed to become Chair of the Board of Directors of the A.E. Lalonde Accelerator Mass Spectrometry Laboratory at the University of Ottawa in May.

Geofirma Staff presented at GeoOttawa 2017;
John Avis presented “Groundwater Transport of Radionuclides in a Crystalline Geosphere“. He discussed the relative importance of different transport processes is important in terms of defining site characterization requirements for actual repository sites. Sensitivity cases addressing geosphere transport parameters provided initial insight into dominant transport processes. Probabilistic simulations were used to further investigate relative importance of various transport processes and the sensitivity to parameters describing the processes.
Sean Sterling presented “Elevated Background Metals in Champlain Sea Deposits – Ottawa Region“. This work presents a thorough review of approximately 60 studies with soil concentrations in fine grained Champlain Sea deposits near Ottawa and uses the data from 285 representative samples to calculate geo-regional background soil standards to better represent the native materials in Eastern Ontario. These newly calculated values are proposed to replace the current MOECC O.Reg. 153/04 Table 1 background standards and follow the same methodology and rationale as the original MOEE Table 1 background standards for the Province of Ontario in 1993.
Othman Nasir presented “A Concept for Modelling Evolution of Permeability in Re-hydrating Bentonite“. He described a simple model developed in the TOUGH2 code based on changes in multi-scale porosities to predict the evolution of bentonite permeability during the hydration process.
Robert Walsh presented “Measurement and modeling of stress changes caused by underground pressurization of gas“. This talk and paper describe how the mechanical response of caprocks isolating underground gas storage reservoirs was modeled using combined two-phase flow (TOUGH2) and geomechanical (FLAC3D) models. Data obtained from a deep borehole also provided indirect observations of the geomechanical response of the caprock.
Dick Jackson presented a review of a 2 km gasoline contamination plume in San Diego, California and its remediation for which he had been the City’s advisor for 12 years. Entitled “Qualified Success of a Monitored Natural Attenuation of Gasoline Contamination in an Extremely Long Plume”, the talk focused on how a misinterpretation of the hydrogeology of the aquifer transmitting the contamination led to the failure by the polluter to capture the leading edge of the plume. Overall, the use of soil vapor extraction was successful in removing most, but not all, gasoline LNAPL, while monitored natural attenuation and groundwater extraction did cause the removal of BTEX and MTBE compounds, although not the TBA at the leading edge of the plume. The TBA contaminated the most transmissive section of the aquifer, that part that had been used by the City of San Diego prior to World War II as its groundwater supply.
Dick Jackson was also co-author of three other papers at GeoOttawa on redox measurements, seepage pathways in hydraulic fracturing and brine disposal in southwestern Ontario.

They demonstrate that the daughter TBA plume is longer than the parent MTBE plume because of the remedial response at the site in San Diego. A companion paper has been recently published by Rob Sengebush of INTERA and Dru Heagle and Dick Jackson in Environmental & Engineering Geoscience on the Quaternary History and Groundwater Quality in this aquifer.
