Item Banking Groundwater - A study examining aquifer storage and recovery for groundwater sustainability in MinnesotaBilotta, John P.; Arnold, William; Kang, Peter; Seonkyoo, Yoon; Shandilya, Raghwendra N.; Bresciani, Etienne; Lee, Seunghak; Kirk, Josh; Levers, Lucia; Bohman, Brian; Kirby, Eileen; Runkel, Anthony; Xiang, Galen; Gassman, Phillip; Valcu-Lisman, Adriana; Jennings, Carrie E.; jbilotta@umn.edu; Bilotta, John P; University of Minnesota Water Resources Center; FreshwaterSome of the more than 75% of Minnesotans who rely on groundwater may find it in short supply in the face of population, land-use and climate change. Aquifer storage and recovery (ASR) is a technological approach to treat and inject clean water into an aquifer for temporary storage. The hydrogeological characteristics and the chemistry of the source water and aquifer impact treatment needs prior to injection and after extraction. Aquifer properties that control how water moves determine the volume and rate of water injected. This study examined four different kinds of aquifers across Minnesota with unique pressures to determine their suitability for ASR. The study findings suggest three may be suitable for ASR. The Buffalo aquifer in Moorhead has variable injection capacity and multiple sources of water for injection. Water quality issues of arsenic, sulfate, manganese, and hardness would require treatment after extraction. The Jordan aquifer in Rochester faces increased pressure from growth and nitrate contamination in the surrounding agricultural areas. The wastewater treatment plant could provide adequate source water if treated. Woodbury faces pressure from increasing population and PFAS contamination of the Jordan aquifer. ASR could recharge groundwater from wastewater treatment plants and also be integrated with PFAS remediation scenarios by reinjection of treated groundwater. ASR is not recommended for the surficial sand aquifer in the Straight River Groundwater Management area in north central Minnesota because there is no source of water to make it a feasible option at this time. Cost-benefit analysis combined with a sensitivity analysis of economic factors should be a component of ASR project feasibility. Modified state well code and a streamlined permitting path would allow more successful development and deployment of ASR. State adoption of control over Class V injection wells from the USEPA is also necessary.Item Bear Creek surface water simulation modeling demonstration.(University of Minnesota, Water Resources Research Center. Special report 13., 1987-06) Anderson, Kevin L.This report summarizes a test of the interface between existing computer models and water-resource data in Minnesota's current geographic information system.Item Crop production response to moisture supply in Minnesota.(University of Minnesota, Water Resources Research Center, 1987-06) Brown, Dwight A.; Gersmehl, Carol A.; Drake, Janet; Skaggs, Richard H.The purpose of this report is to define how variations in moisture affect state-wide crop production. To accomplish this goal we controlled geographic variations in the response of crops to changing technology, and regional differences in the severity and timing of wet and dry periods. The regional differences from local norms or unexpected values. Technology changes are controlled by subtracting the general trend in yield from the actual yield technology.Item Directory of water resources expertise in Minnesota Universities and Colleges(University of Minnesota, Water Resources Research Center, 1991-05)Item Directory of water resources expertise in Minnesota Universities and Colleges(University of Minnesota, Water Resources Research Center., 1987-04)Item Experimental Acidification of Little Rock Lake, Wisconsin:Baseline studies and predictions of lake responses to acidification(University of Wisconsin, Water Resources Research Center, 1985-12) Brezonik, P.L.; Baker, L.A.; Detenbeck, N.; Eaton, J.G.; Frost, T.M.; Garrison, P.J.The experimental acidification of a two-basin lake in northern Wisconsin is described. Background studies on the lake began in 1983, and the lake basins were separated by a vinyl curtain in August 1984; acidification of the north basin began in spring of 1985.Item Fields to streams: managing water in rural landscapes Part 1: Water shaping the landscape(University of Minnesota Extension, 2015) Lewandowski, Ann; Everett, Leslie; Lenhart, Chris; Terry, Karen; Origer, Mark; Moore, RichardFields to Streams details connections between land use, runoff, and water quality in rural landscapes. The two-part book highlights practices to improve and protect rural streams and shows how land management can affect the rate of runoff that shapes them. The publication was prepared for landowners, land managers, and the conservation professionals who work with them to help them talk about and address local watershed issues. It draws on research from Minnesota and Iowa, providing concise explanations and graphics to highlight concepts and practices. Part One, "Water Shaping the Landscape," explains the role of Minnesota's geology, changing rainfall, and land management practices in altering the amount and timing of runoff reaching and shaping streams and rivers. Part Two, "Managing Sediment and Water," describes practices for managing crops, drainage systems, surface runoff, wetlands, impoundments, and stream corridors to reduce peak flows and lessen the amount of streambank, bluff, and ravine erosion.Item Fields to streams: managing water in rural landscapes Part 2: Managing sediment and water(University of Minnesota Extension, 2015) Lewandowski, Ann; Everett, Leslie; Lenhart, Chris; Terry, Karen; Origer, Mark; Moore, RichardFields to Streams details connections between land use, runoff, and water quality in rural landscapes.

The exercise has been extremely useful in giving the Water Resources Research Centers an opportunity to examine, restate and update their goals and objectives to prepare a program for each state for the immediate future.Item Groundwater research needs in Minnesota:Summary of workshop sponsored by the Water Resources Research Center(University of Minnesota, Water Resources Research Center, 1989-09)Item Guide to groundwater sensitivity rating techniques.(University of Minnesota, Water Resources Research Center, 1992-09) Geier, Theodore W.; Perry, James A.Item Guide to groundwater senstivity rating techniques.(University of Minnesota, Water Resources Research Center, 1992-09) Geier, Theodore W.; Perry, James A.The protection of ground water quality has become an important issue in recent years. Ground water systems have traditionally been viewed as inexhaustible sources of clean water, but it is now clear that they require sound management and protection if they are to continue to provide the needs of modern society.Item The Impact of Erosion Control Structures on the Water Quality of the Cobb River in Blue Earth County, Minnesota.(University of Minnesota, Water Resources Research Center, 1984-03) Davidson, Mark J.This study provides a baseline investigation of the impact of erosion control structures on water quality of a receiving body in Blue Earth County, South Central Minnesota. To assess this impact, three were monitored and compared for water quality (PO 4-P, NO3-N, TKN, turbidity, flow, conductivity) during the 1982 ice-free period.Item Impaired Waters Research Symposium Final Report(2008-02) Sleeper, Faye; Wilson, BruceItem Minnesota drought.(University of Minnesota, Water Resources Research Center, 1987-05) Swerman, Rodney R.; Baker, Donald G.; Skaggs, Richard H.Drought is an ordinary and expected part of the climate of any location. However, there are a few measures of drought and often it is difficult to recognize when a drought has begun and when it has ended. In the United States, the Palmer Drought Severity Index (PDSI)is the most commonly employed measure of drought. Examination of the averages and variability of the PDSI is needed to draw conclusions about the temporal and geographic patterns of drought over Minnesota is to be drawn.Item Minnesota Statewide Conservation and Preservation Plan(2008) Swackhamer, Deborah L.; Colman, Jean; Shardlow, JohnItem Minnesota water and sewer rates revisited.(University of Minnesota, Water Resources Research Center., 1988-10) Easter, K.
