Contents

This open file contains geochemical data for lake sediment and water samples collected in the Abitau Lake area (NTS 75-B) in the Northwest Territories in 2015.  Data for 65 elements in lake sediments (Appendix 1) and 65 elements in lake waters (Appendix 2) are included with this report.  Quality control data is listed in Appendix 3.
