Phase 2 initial borehole drilling and testing at IG_BH04/05/06, Ignace area: WP07 data report - opportunistic groundwater sampling for IG_BH06

The Phase 2 Initial Borehole Drilling and Testing at IG_BH04/05/06 project in the Wabigoon Lake Ojibway Nation (WLON) – Ignace area of Ontario, is part of the Phase 2 Geoscientific Preliminary Field Investigations of the Nuclear Waste Management Organization's (NWMO) Adaptive Phased Management (APM) Site Selection Phase. This project involves testing of deep borehole IG_BH04 and the drilling and testing of deep boreholes IG_BH05 and IG_BH06 in the Revell site within the identified Potential Repository Area (PRA). The work comprised of a total of eleven work packages and was carried out by a team led by Golder Associates Ltd. (now WSP Canada Inc.) on behalf of the NWMO. The IG_BH06 program is described in a Borehole Characterization Plan (BCP) for IG_BH06. This report describes the methodology, activities and results for Work Package 7 (WP07): Opportunistic Groundwater Sampling for IG_BH06, which includes identification of permeable intervals during drilling (WP02 and WP03) and hydraulic testing (WP06), collection and in-field analysis, and laboratory analysis of samples. This report also describes the analysis of the fresh water collected as part of Work Package 2 (WP02): Borehole Drilling and Flushing for IG_BH06. IG_BH06 is an inclined borehole, all depths referred to in this report are in meters below ground surface along the length of the borehole (mbgs along hole), rather than true vertical depth. (author)
