The Project approach is based on our Project team’s familiarity with the MDH requirements, and staff who have completed more than 40 Part 1 WHP Plan projects in Minnesota, and conducted hydrogeologic assessments of the Ordovician-age Prairie du Chien and Cambrian-age Jordan Sandstone aquifer that the City’s wells are completed in. Spheros has compiled and reviewed the following information, which provided the basis for our Project approach: the MDH Scoping Decision Notice, well logs from the MWI Database, maps from the Minnesota Department of Natural Resources (MDNR) and Minnesota Geological Survey (MGS) Washington County Hydrogeologic Atlases, MetroModel 3 (MM3) groundwater model, USGS’ and DNR’s Northeast Metro groundwater modeling, communication with MDH staff, and the previous 2013 Part 1 WHP Plan completed by our Project team. A successful Part 1 WHP Plan is developed through a comprehensive analysis and evaluation of existing data and new data obtained by performing a number of tasks. Spheros will approach the Project by completing the proposed tasks in an efficient and cost-effective manner that addresses the specific aspects of the wellfield and meets the requirements of the MDH and MR 4720.5100 to 4720.5590. The ultimate goal of the WHP Plan is to ensure that the aquifer utilized by the City is protected as the current and future water sources. The first phase of this process is to delineate the WHPAs. This is done by characterizing the local hydrogeology, developing/updating a site- specific conceptual hydrogeologic model, delineating the 1-, 5-, and 10-year times-of-travel (capture zones) used to delineate the WHPAs for all City wells, completing a fracture flow analysis, assessing the need for a surface water capture area or conjunctive delineation, and assessing the vulnerability of the wells and the aquifer(s) within the delineated DWSMA. The need for a surface water delineation will be evaluated given the source aquifer and vulnerability; therefore, costs for a conjunctive delineation are included in this proposal. To begin the WHPA delineation process, initial collection of the data elements that will be outlined in the scoping meeting notes will be completed. Typically, most of this information is available through the public domain. Using the assembled data, Spheros will make a general evaluation of these criteria and build upon existing information to refine the existing conceptual hydrogeologic model that is specific to the City and surrounding area. Following development of the initial conceptual hydrogeologic
