4.0 STUDY CONCLUSIONS <br />4.1. Pumping Conditions Impacts On LWWTP <br />It is understood that increases in water table elevations in the vicinity of the <br />LWWTP would be an unacceptable result of the Mining Operation. Pumping <br />conditions will produce the opposite effect, which is to lower the local water table <br />during the life of the mining operation. Monitoring of the local water table <br />indicates that the aquifer is un-confined in this area. Unconfined aquifers do not <br />compress (settle) under dewatering and therefore the ground in an around the <br />LWWTP will not settle as the result of dewatering <br />4.2. Reclamation Impacts On LWWTP <br />It is understood that increases in water table elevations in the vicinity of the <br />LWWTP would be an unacceptable result of the Reclamation Plan. The <br />reclamation grading plan was designed to minimize the potential for any increase <br />in groundwater table elevations on the LWWTP property. <br />The modeling results demonstrate that this strategy is predicted to be a success. <br />Modeled reclamation water table elevations are predicted to be lower in the area <br />of the LWWTP (see Sheet 4). <br />4.3. Impacts On SurFace And Ground Water <br />As outlined in this modeling report the operation will directly influence aspects of <br />the surface and groundwater systems in the area. For example groundwater <br />levels will be lowered in the vicinity of the gravel pits during mining and <br />dewatering operations. Sheets 3,5, & 7 of the modeling report illustrate the <br />maximum drawdown predicted by the model. In addition, the operation will <br />induce increased recharge into the aquifer from the river during dewatering. <br />However, it was not the purpose of this model to quantify effects on the river. <br />4.4. Impacts On Existing Wells <br />There are no alluvial wells within 600 feet of the proposed gravel mines. The <br />wells nearest the project are two stock wells (permits 79969 and 79970) located <br />in the SE of the NW of Section 19, T5N, R68W. These two wells are south of the <br />river approximately 1500 feet from the Gardels mines. They are both owned by <br />the applicant. <br />Gardels Pit <br />Revised Groundwater Modeling Report <br />9of9 <br />
