Regional lake-sediment geochemical data from northwestern Manitoba (NTS 064-F) : re-analysis and QA/QC evaluation / J.B. Bourdeau. : M183-2/8948E-PDF
"This report presents the geochemical data, quality assurance and quality control (QA/QC) results ofthe re-analysis of lake sediment samples collected from north-western Manitoba (NTS 064-F). The original survey was conducted in 1984 and the re-analysis in 2021. Original survey results are presented in OF 1104. A total of 1,024 lake sediment samples were re-analyzed, covering an area of 13,400 km², averaging a density of 1 sample per 13 km². Samples were analyzed for 65 elements via modified aqua-regia – ICP-MS and 35 elements via INA. To ensure high quality data, the geochemical data was evaluated for contamination, accuracy, precision and fitness-for-purpose (ANOVA). QA/QC results have identified a number of elements to be monitored carefully for future analyses. Overall, the dataset is of good quality"--Abstract, page 2.
