He leads well siting studies, <br />aquifer pumping tests, groundwater modeling, and wellhead protection plans <br />for municipal water suppliers in Minnesota and Wisconsin. He builds Metro <br />Model 3 submodels, analyzes aquifer tests in AQTESOLV, and manages all <br />project GIS and figure production. Mark uses his expertise to provide organized <br />and concise data in a format useful to all project stakeholders. <br />Mark brings significant local experience, having mapped the City of <br />Ramsey source aquifer in 2021. His well siting study experience includes <br />work for the cities of Sartell and Rosemount in 2025. <br />EXPERIENCE <br />Centralized Water Treatment Plant, Source Water Analysis for Feasibility <br />Study — Ramsey, MN <br />Mark served as scientist on this source water analysis project for the 10 <br />MGD water treatment plant study. The project mapped Tunnel City-Wonewoc <br />thickness and extent, calculated aquifer parameters from City well records, <br />built a Metro Model 3 submodel of the wellfield, modeled present-day and 2040 <br />drawdown, and identified three well siting areas for future municipal wells. <br />2025 Hydrogeologic Well Study — Sartell, MN <br />Mark was project manager and scientist for this two-phase wellfield evaluation <br />for a new supply well. The project included a desktop review of geology, well <br />records, and SCADA interference data, then two sonic exploratory borings and <br />step tests with the drilling contractor as SEH subcontractor. Sieve analysis, <br />screen design, water quality sampling, and well location recommendations were <br />also completed. <br />2025 Well Siting and Aquifer Interference Analysis — Rosemount, MN <br />As project manager and scientist, Mark completed the well siting and aquifer <br />interference analysis, including the Hantush-Jacob aquifer analysis of published <br />data, projected drawdown at domestic and public supply wells, and on -site <br />drilling coordination. <br />Wellhead (WHPP) Protection Plan, Well 8 Pump Test — Anoka, MN <br />Mark served as the geologist responsible for updates to the City's Part I <br />Wellhead Protection Plan, including a constant -rate pump test to set aquifer <br />parameters for the City's groundwater model. <br />Water Well Studies — Federal Cemetery Clients <br />New well study for an expansion site in the Madison aquifer (South Dakota) and <br />a PFAS irrigation well investigation (Minnesota). <br />WHPP PART I DELINEATIONS AND PART II PLANS FOR THE FOLLOWING CLIENTS: <br />o Shakopee Public Utilities <br />o Saint Paul Regional Water Services <br />o Vadnais Heights, MN <br />o Anoka, MN <br />o Cambridge, MN <br />o Waite Park, MN <br />o Brownton, MN <br />o Deer River, MN <br />SHORT ELLIOTT HENDRICKSON INC. <br />WELL SITING ASSESSMENT FOR MUNICIPAL WELLS #9 AND #10 <br />
