A non-hierarchical syncretic framework to assess environmental contaminants by interdisciplinary integration of geoscience methods and culturally-centred Indigenous knowledge exchange approaches

Different soil and water pollution sources around an undisclosed First Nation (The FN) in Northern Ontario (Canada) are linked by community health documents and oral histories to a cluster of blood cancer. The site's environmental hydrogeochemical records available are difficult to follow, whereas geophysical data reveals possible pathways of contaminants displayed as 3D maps of subsoil contrasting geoelectrical properties. Through an Indigenous Integrated Knowledge Translation (IIKT) strategy, we have co-constructed with The FN an interdisciplinary framework of non-hierarchical syncretic exchange between geoscience-based environmental engineering praxes and Indigenous Knowledge. The IIKT is articulated through Talking Circles of flexible multidirectional exchanges between The FN and the research team, to address community-identified needs and maintain qualitative and contextual value in the investigative agenda. The Talking Circles have guided our efforts to collect, handle, integrate, and understand hydrogeochemical and geophysical data. Thus, we build a culturally-appropriate knowledge base for self-sufficient environmental monitoring capacities with the community to ensure informed decisions about the land. The sustainability of the proposed framework relies on the non-invasiveness and low cost of the environmental/engineering tools used, the transparency of the community-driven results obtained, and its scalability to other Indigenous communities.
