| Résumé | (disponible en anglais seulement)
For over three weeks, fire suppression teams sought to control the 2018 Parry Sound 33 Wildfire (covering 11,362 hectares in northeastern Ontario). Following
the fire, the wide spread concern has been the impact of the Parry Sound 33 Wildfire upon the Key Harbour First Nation's and Henvey Inlet First Nation's water security. This in turn has sparked groundwater geochemistry questions. Our research seeks
to understand one question: how can the post-Parry Sound 33 fire water quality research provide guidance for future ground water research in Southern Ontario and across Canada?
Informed by research from i) post fire mobilization of contaminants
into surface water resources; ii) short term impacts of fire events on karst; and iii) community based fire management, this project has several objectives:
a) Provide gap analysis of the post-fire groundwater for drinking water quality
research;
b) Detail how Canadian universities and research institutions take a strategic view of post-fire water quality research to support land use planning and public health and safety initiatives;
c) Document actionable information products
created to communicate to communities how to manage post fire water quality.
This paper presents preliminary results of our research, noting:
Contamination of high quality potable water in groundwater can occur through natural events such as
wildfires because wildfires modify the surface environment by combusting vegetation and changing soil properties;
Most prior research on post-fire water quality research has focused on surface water to determine fire-prone forested water source
areas;
The emerging field of post fire contamination of water sources is receiving considerable attention, evidenced by the 2018 NSERC funded Water Institute/University of Waterloo project. But there is little research being done to understand the
vulnerabilities of groundwater aquifers to post fire debris, sediment and chemical constituents (indicators that could be included in future assessments).
This paper is intended to inform discussions on the preparation of suitable post fire water
management plans in order to maintain drinking water quality in a cost-effective manner. |
