Red Creek Quarry Baseline Water Investigation Section 1 <br /> <br /> <br />1-2 <br />DRAFT for review purposes only. Use of contents on this sheet is subject to the limitations specified at the end of this document. <br />• Section 6 presents interpretations of the results. <br />• Section 7 presents the conclusions of the RCQ baseline investigation. <br />• Section 8 lists the limitations of this report. <br />• Section 9 lists the references cited throughout this report. <br />• Appendices A through I: The appendices include groundwater well completion logs, field project <br />documentation, laboratory analytical reports, data validation reports, plots of hydrologic data, <br />and tabular analytical data. <br />1.1 Baseline Water Investigation Objectives <br />To meet the requirements of the DRMS permit application, BC developed a general scope of work to <br />investigate surface and groundwater conditions at the Site. The objectives of the Baseline Water <br />Investigation are to: <br />• Evaluate whether water is present within the mined limestone product (or underlying material) <br />and if it be impacted by future mining pit development. <br />• Assess the timing of depletions from water consumptively used during mining operations. <br />In addition to meeting the DRMS permit requirements, the Baseline Water Investigation was <br />developed to collect water quality and quantity data to provide Holcim with scientific, defensible <br />evidence of the water quality at the site prior to any proposed mining activities. Additionally, the <br />baseline study provides metrics for comparisons of the water quality or quantity of the site to identify <br />any potential impacts. <br />1.2 Baseline Water Investigation Scope of Work <br />The scope of work for the Baseline Water Investigation included the following tasks: <br />1. Collect field data. <br />2. Establish the baseline surface and groundwater quality prior to mining activities. <br />3. Assess the location and estimate the volumes of surface water flow within Red Creek. <br />4. Assess groundwater flow and direction across the Site. <br />5. Estimate the amount of mined product below the water table to evaluate the impact of <br />groundwater flow that may contribute to Red Creek. <br />
