DRMS ANNUAL REPORT - GROUNDWATER MONITORING REPORT <br /> SITE: L.G. Everist, Inc. - Fort Lupton Sand and Gravel, M-1999-120 <br /> DATE: June-2017 Page 2 of 2 <br /> MW11, MW12, MW13, MW16 -These wells are located in and around areas which have been <br /> released from the DRMS permit, and so are now within the City of Aurora's reservoir properties. <br /> L.G. Everist does not have access to them. <br /> MW14-This well is considered internal to LGE operations. The groundwater has dropped <br /> below the baseline level, however this well is located in the southeast section of the Parker- <br /> Panowitz cell. Changes in groundwater levels around this well would only affect LGE, therefore <br /> no mitigation is necessary. Note that the nearest external well, MW45 (located just north of the <br /> Parker-Panowitz slurry wall) is in compliance. <br /> MW49, MW60 -These wells are internal to L.G. Everist operations. They are located within the <br /> confines of the Vincent West slurry wall liner. They have fallen slightly below baseline ranges. <br /> Changes in water levels in these levels would only affect the operator, so therefore no mitigation <br /> is necessary. <br /> MW47, MW52, MW63 -These wells are internal to L.G. Everist operations. They are located <br /> within the Swingle-South slurry wall. They have fallen slightly below baseline ranges, but that is <br /> to be expected being inside a slurry-walled reservoir. Changes in water levels in these levels <br /> would only affect the operator, so therefore no mitigation is necessary. <br /> As mentioned above, all other existing wells are within baseline ranges. Also, as noted above, <br /> L.G. Everist has investigated the data and compared monitoring well results with their locations <br /> and nearby activities, whether LGE or neighboring mining operations. Most wells that have <br /> fallen outside of baseline ranges are internal to LGE operations, and are not affecting anyone <br /> but LGE, therefore no mitigation is necessary. As MW8, MW9 and MW10 are the only external <br /> wells that are outside of baseline ranges and are either close to a neighboring mine, or quite far <br /> from any mine (MW10). The lower water levels are not having an adverse effects on any <br /> neighboring residences. As LGE is not the cause of the groundwater decrease in these three <br /> external wells, mitigation is not required on our part. We continue to monitor all our existing <br /> wells on a monthly basis. <br /> FL-DRMS-AnnRpt&GrWtrMon-2017 docx <br />
