DP Spring <br /> The field parameters were measured on July 25, 2023. The flow is measured by timing the fill rate <br /> of a five-gallon bucket. Field parameters from DP Spring are measured in the stock tank located <br /> at the spring. The field sampling form is provided in Appendix 3. Flow rates and field parameters <br /> at DP Spring are summarized in Appendix 1, Attachment 4, laboratory data are included in <br /> Appendix 5. <br /> In conjunction with monitoring activities, EFRI Environmental Field Technician, Trent Holliday, <br /> accompanied by Bruce Smith, Principal Hydrogeologist from Western Water & Land, Inc., <br /> performed a pedestrian survey of the Top Rim sandstone within Lumsden Canyon. In accordance <br /> with Exhibit T (Environmental Protection Plan) of the DRMS-approved 112d Permit Application, <br /> one perceived seep was observed, measured for approximate flow rate and sampled for laboratory <br /> analysis. Flow rates and field parameters for the grab sample are summarized in Appendix 1, <br /> Attachment 11. The field sampling form is provided in Appendix 3. Survey notes are included in <br /> Appendix 4. Analytical laboratory results are summarized in Appendix 2, Table 7 and laboratory <br /> data is provided in Appendix 5. <br /> Mr. Smith suspects that the perceived seep may be derived from DP Spring and potentially other <br /> shallow groundwater in the vicinity. According to Mr. Smith, it cannot be said that this water or a <br /> portion of this water originates from the Top Rim Sandstone, simply because an outcrop is not <br /> present at this location to observe such flow. <br /> PR Spring <br /> An analytical sample was collected, and parameters were measured at PR Spring on July 25,2023. <br /> The flow is measured by timing the fill rate of a five-gallon bucket. Field parameters from PR <br /> Spring are measured in the stock tank located at the spring. The field sampling form is provided <br /> in Appendix 3. Flow rates and field parameters at PR Spring are summarized in Appendix 1, <br /> Attachment 5. The historical analytical data from PR Spring are summarized in Appendix 2,Table <br /> 2. <br /> Monitoring Well W-1 <br /> Monitoring Well W-1 was installed on October 12, 2008 for the purpose of characterizing and <br /> monitoring groundwater quality downgradient of the waste rock storage area. <br /> Monitoring Well W-1 was sampled and measured for the static groundwater level and field <br /> parameters on July 25, 2023. The field sampling form is provided in Appendix 3. <br /> Water levels and field parameters are summarized in Appendix 1, Attachment 6. The analytical <br /> data from Monitoring Well W-1 are summarized in Appendix 2, Table 3. <br /> 3 <br />
