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 on site or <br />nearby, explain the methodology used to determinethis. <br />1) The depth to ground water appears to vary greatly across the site. During the geotechnical <br />evaluation of the site 16 soil borings were completed across the site. Water tables, when <br />they were observed, ranged from 894.9' to 919.1' MSL. A map of the boring locations and <br />boring logs documenting water tables observed is included in Appendix D — Geotechnical <br />Report. <br />The Minnesota Department of Natural Resources Cooperative Groundwater Monitoring <br />Website maintains data on ground water levels. The closest, actively read, observation <br />well to the Project site is DNR Observation Well #02012 (MDH #208573), which is located <br />approximately 2 miles north of the Project site. The water level in the most recent data <br />record (September 27, 2024) was measured at 890.57' MSL. <br />2) The Project site is not located within any Wellhead Protection Area (WHPA). However, the <br />Project site is located within close proximity to the Lino Lakes East WHPA. The boundary <br />of the Lino Lakes East WHPA is illustrated on Appendix A — Figure 9. <br />Per the City's 2015 Wellhead Protection Plan, the Project site is located within the <br />moderate vulnerability portion of the City's 2020 Drinking Water Supply Management <br />Area (DWSMA) Evaluation that incorporated Well No. 6, which will appear in the City's <br />next Wellhead Protection Plan update around 2025. <br />3) According to the Minnesota Department of Health — Minnesota Well Index, there is one <br />identified well located within the Project site. This was Well #420603, a domestic well. <br />Groundwater resources located within and adjacent to the Project site are illustrated on <br />Appendix A — Figure 9. <br />b. Describe effects from project activities on water resources and measures to minimize or mitigate <br />the effects in Item b.i. through Item b.iv. below. <br />i. Wastewater - For each of the following, describe the sources, quantities and composition of <br />all sanitary, municipal/domestic and industrial wastewater produced or treated at the site. <br />1) If the wastewater discharge is to a publicly owned treatment facility, identify any <br />pretreatment measures and the ability of the facility to handle the added water and <br />waste loadings, including any effects on, or required expansion of, municipal <br />wastewater infrastructure. <br />The Project site is located within the City of Lino Lakes' Sewer District 4. Per The 2040 Plan, <br />future improvements within this district will discharge to the White Bear Township trunk <br />sanitary sewer in Centerville Road, then to the Metropolitan Council Environmental <br />Services (MCES) regional interceptor collection system, and ultimately to the MCES <br />Metropolitan Wastewater Treatment Plant (WWTP). <br />Page 15 <br />
