Some 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.
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, Richard
Fields 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.

Watershed Research Symposium February 21, 2013 Final Report
(2013) Sleeper, Faye
The University of Minnesota Water Resources Center (WRC) led and hosted a Watershed Research Symposium on February 21, 2013 to suggest a water resources research agenda in Minnesota for the next five years, 2013 through 2018. The WRC and Department of Bioproducts and Biosystems Engineering hosted a similar event, the Impaired Waters Research Symposium, in February 2008, which resulted in a five-year research agenda. The purpose of both symposia was to bring together researchers, state decision makers, practitioners and citizen representatives to understand the current state of research in managing Minnesota’s water resources and to identify gaps in information and knowledge that could be bridged through additional research. The final report from the first symposium can be found at: http://z.umn.edu/researchsymp1.
A Primer on Limnology
(1975-03) Lundquist, John B.
Limnology is the scientific study of inland waters, including lakes, ponds, and rivers. In this day of widespread social concern over the impact of human activity on natural environments, limnology is becoming an increasingly important practical science. Private and public decisions based on the best available limnological information will be necessary if we hope to protect, manage, or restore the quality of lakes and other waters.

Water supply issues in the metropolitan Twin Cities area: Planning for future droughts and population growth, summary of a workshop, October 25, 1988.
(University of Minnesota, Water Resources Research Center, 1988) Brezonik, P.L. (editor)
The severe drought of 1988 focused attention on water supply concerns in the metropolitan Twin Cities area....Six panels addressed these issues at the workshop in the following order: 1. Surface and groundwater resources of the region ; 2. Climate trends and regional precipitation patterns ; 3. Water use patterns in the metro area ; 4. Water uses and user interests in the Mississippi Headwaters region ; 5. Legal issues concerning water transfers and regulation of Headwaters reservoirs and 6. Alternative water supply possibilities for the metro area.
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.

Relationship between climate and the mean annual flow of the Mississippi River at St. Paul
(University of Minnesota Water Resources Research Center, 1987-06) Skaggs, Richard H.; Brown, Dwight A.
This study demonstrates the use of the simulation of water balance for large areas. It examines the statistical relationship between the mean annual flow of the Mississippi River at St. Paul and the water balance surpluses (water not used in evapotranspiration and soil moisture storage) for the six climatological divisions of Minnesota that contribute to the drainage of the Mississippi and Minnesota Rivers in Minnesota.
