11. Water resources: a. Describe surface water and groundwater features on or near the site in a.i. and a.ii. below. i. Surface water - lakes, streams, wetlands, intermittent channels, and county/judicial ditches. Include any special designations such as public waters, trout stream/lake, wildlife lakes, migratory waterfowl feeding/resting lake, and outstanding resource value water. Include water quality impairments or special designations listed on the current MPCA 303d Impaired Waters List that are within 1 mile of the project. Include DNR Public Waters Inventory number(s), if any. There are no surface waters including lakes, streams, wetlands, intermittent channels, and county/judicial ditches on the Site. The soils found over the Site are well drained with rapid permeability characteristics. There two public waters (15P and 4W) within one mile of the Site. Public Water 15P is a protected basin associated with Tibbets Brook and Rice Lake located west of the Site, U.S. 169 and the Elk River Landfill. Public water 4W is a protected wetland located approximately one mile southeast of the Site. Figure 7: DNR Public Waters, shows the locations of nearby public waters. Although there are no wetlands located on the Site itself, the National Wetland Inventory (NWI) indicates a number of wetlands located in the area surrounding the Site. Figure 8: NWI Wetlands, illustrates the location of wetlands in the surrounding area. Based on information available on the MPCA's Impaired Waters Viewer, there are no MPCA 303d Impaired Waters within one mile of the Site.B ii. Groundwater— aquifers, springs, seeps. Include: 1) depth to groundwater; 2) if project is within a MDH wellhead protection area; 3) identification of any onsite and/or nearby wells, including unique numbers and well logs if available. If there are no wells known on site or nearby, explain the methodology used to determine this. 1) The depth to groundwater at the Site ranges from approximately 13 feet to 92 feet below the ground surface with the variability due to the irregular topography. The groundwater elevation ranges from approximately 956 feet above msl in the southwestern portion of the Site to 960 feet above msl in the northeastern portion of the Site. The direction of groundwater flow is towards the southwest. Groundwater elevation data is from the Elk River Landfill Expansion DEIS.9 2) The Site is not located in a Minnesota Department of Health (MDH) Wellhead Protection Area (WHPA) or a Drinking Water source Management Area (DWSMA).10 3) The Minnesota Well inventory11 was used to identify the wells within a half mile of the Site. Geographic Information System Data was downloaded from the Minnesota Well Index website to obtain coordinates of the wells. The Elk River Landfill is located to the west of the Site, across US 169. The Elk River Landfill has four monitoring wells located $https://www.pca.state.mn.us/water/impaired-waters-viewer-iwav 9 Elk River Landfill Expansion Draft Environmental Impact Statement October 2005 io http://www.heaIth.state.mn.us/divs/eh/water/swp/maps/gis/whpa.pdf "http://www.health.state.mn.us/divs/eh/cwi/ Environmental Assessment Worksheet Page 13 Elk River Sand and Gravel Mines: Tiller Corporation and Max Steininger, Inc.
