Summary:

"This report presents the geochemical data, quality assurance and quality control (QA/QC) results of the re-analysis of lake sediment samples collected from northeastern Saskatchewan (NTS 064-E, 074-A and H). The original lake survey was conducted in 1984 and the re-analysis in 2021. Original survey results are presented in OF 1643. A total of 1,179 lake sediment samples were re-analyzed, covering an area of 18,000 km², averaging a density of 1 sample per 13 km². Samples were measured for 65 elements via modified aqua-regia - ICP-MS. To ensure high quality data, the geochemical data was evaluated for contamination, accuracy, precision and fitness-for-purpose. QA/QC results have identified a number of elements to be monitored carefully for future analyses. Overall, the data is of good quality"--Abstract, page 2.
