page 9 <br /> <br />NOTE: For silica sand projects, the EAW must include a hydrogeologic investigation assessing the <br />potential groundwater and surface water effects and geologic conditions that could create an increased <br />risk of potentially significant effects on groundwater and surface water. Descriptions of water <br />resources and potential effects from the project in EAW Item 11 must be consistent with the geology, <br />soils and topography/land forms and potential effects described in EAW Item 10. <br /> <br /> <br />11. Water resources: <br />a. Describe surface water and groundwater features on or near the site in a.i. and a.ii. below. <br />i. Surface water - lakes, streams, wetlands, intermittent channels, and county/judicial ditches. <br />Include any special designations such as public waters, trout stream/lake, wildlife lakes, <br />migratory waterfowl feeding/resting lake, and outstanding resource value water. Include <br />water quality impairments or special designations listed on the current MPCA 303d Impaired <br />Waters List that are within 1 mile of the project. Include DNR Public Waters Inventory <br />number(s), if any. <br /> <br />The DNR’s Public Waters Inventory and National Wetlands Inventory maps were reviewed <br />and there are no surface water features within the project area (Figure 12). There are no listed <br />MPCA 303d Impaired waters within 1 mile of the project; however, the Mississippi River <br />(approximately 2.3 miles west) is listed as impaired for bacteria, and water from this area of <br />Saint Anthony drains to the river. <br /> <br />ii. Groundwater – aquifers, springs, seeps. Include: 1) depth to groundwater; 2) if project is <br />within a MDH wellhead protection area; 3) identification of any onsite and/or nearby wells, <br />including unique numbers and well logs if available. If there are no wells known onsite or <br />nearby, explain the methodology used to determine this. <br /> <br />Based on data gathered from well logs (Appendix C), the depth to groundwater varies <br />between 68 - 125 feet across the project area. Based on the preliminary findings from the <br />developer’s environmental consultant, water is present approximately 6 feet below the <br />surface in some areas. This is most likely a perched groundwater condition. <br /> <br />The project is not located in a MDH wellhead protection area. The project is in Minneapolis’s <br />Drinking Water Supply Management Area for Surface Water. The wells listed below in <br />Table 5 and shown in Figure 13 are within or adjacent to the project area: <br /> <br />Table 5: Wells within 350 feet of Project Area <br />Well ID Type Status Static Water Level <br />(below land surface) <br />256760 Domestic Inactive 68 ft. <br />276877 Domestic Active 109 ft. <br />247102 Other Abandoned unknown <br />257353 Unknown Sealed 107 ft. <br />507600 Monitor Sealed unknown <br />233267 Commercial Active 125 ft. <br />233887 Domestic Active unknown <br />44
