| Résumé | (disponible en anglais seulement)
The Ontario Geological Survey (OGS) and Geological Survey of Canada (GSC) groundwater collaboration in Southern Ontario is currently half-way through a five
year project cycle ending March 31st 2019. Following earlier updates on work completed this update will be provided under five principal themes.
1. Framework for Sustainable Groundwater Use: The 3D bedrock modelling activity has developed a 57
layer formation working model. This model is being used to guide QA/QC throughout the stratigraphy. Database enhancements are focussed on shallow formation of significance to potable water. A wrap-up document to the November 24th 2015 workshop on a
Groundwater Framework was released as a GSC publication. The surficial modelling work is continuing on data capture and development of an authoritative stratigraphic reference framework and online access via the Groundwater Information Network
(GIN).
2. Supporting Great Lakes Water Accords: Work has advanced on development of a conceptual framework for evaluating groundwater - surface water interactions and impacts on the quality and quantity of water and ecosystems. This aligns well
with issues identified in Annex 8 of the Great Lakes Water Quality Agreement.
3. Methods Development for Regional Groundwater Studies: Methods are being advanced through analysis of seismic reflection, downhole geophysics, geochemistry data and
infrared survey data. Passive seismic data was collected in the Wasaga Beach area in the vicinity of OGS boreholes and OGS-GSC seismic data. The objective is to verify the utility of this technique to mapping depth to bedrock surface. The value of
collecting down-hole seismic profiles using the mini-vibe was investigated and demonstrated to provide significantly improved results. Regional methods for soil moisture studies using Radarsat II and SMOS are ongoing. Data were captured along 20 km
of Lake Simcoe shoreline by an infrared airborne survey to investigate groundwater - surface water interaction and to coordinate with a lake based radon survey.
4. Case Studies: Data collection has been completed in a number of areas. Seismic
reflection data were collected in Simcoe central and Niagara area complimented by borehole geophysics. pXRF analysis of continuous core to develop a subsurface chemostratigraphic framework has been expanded to include Simcoe County and Waterloo. A
geostatistical approach was applied within the Innisfil Creek subwatershed to determine the uncertainty of 18 hydrostratigraphic units. Characterization of Newmarket Till cementation was initiated and preliminary results are available on carbonate
cementation in the matrix. Contract work was initiated on consolidation of information on municipal well information within Source Water Protection documents. Additionally work is ongoing on the hydrostratigraphic classification of wells within the
PGWMN.
5. Science and Technology Exchange: Manuscript submissions are in progress for a special issue of Canadian Journal of Earth Sciences with ten manuscripts in various states of review. It is hoped that a 2017 publication remains feasible.
Project results are available via OGS - GSC publication streams, conference proceedings, and journal publications. An overview document on the project was published in the Ontario Geological Survey Report of Activities for 2016. |

Procès-verbaux pour la géoscience des eaux souterraines à échelle régionale Organisée par la Commission géologique de l'Ontario, la Commission
géologique du Canada et les géoscientifiques de Conservation Ontario. La journée portes ouvertes est prévue pour 2017-03-01 et 02. L'objectif est l'engagement du public et la diffusion de la géoscience dans le sud de l'Ontario au cours de la dernière
année. |
