Summary(Plain Language Summary, not published)
This report presents geochemical data for earth materials collected as part of a regional, low-density geochemical survey (1 site/ 1600 km2) of southern Ontario. The survey provides empirical evidence for natural geochemical background and its variation in unconsolidated mineral particulate deposits. Data in this report support environmental and human health protection by showing geographic variation in relative geochemical hazard potential, and by providing a baseline for estimating levels of contaminant inputs. This report also examines the origins of geochemical variation in unconsolidated deposits in terms of bedrock provenance and mineralogy, surficial geology, weathering, and soil formation. Through that, the report demonstrates how geoscience contributes to the geochemical hazard models that support environmental and human health risk assessment.
