2024-2033 Minnesota Drinking Water Action Plan Community Engagement Feedback Report (March 2024)

The Minnesota Department of Health (MDH) is currently developing a 10-year drinking water plan to better manage drinking water in Minnesota, and Freshwater played a key role in engaging water professionals and the broader statewide community. This report gathered input from 190 residents across seven Minnesota communities of their thoughts on drinking water. View the report.

Study will map potential to recharge Minnesota aquifers (November 2023)

With groundwater shortages becoming a concern in some areas of the state, researchers at the University of Minnesota and Freshwater are developing a first-of-its-kind GIS mapping tool that could help pave the way for managed aquifer recharge in Minnesota.

Also known as water banking, managed aquifer recharge usually involves injecting water into the ground through wells, or constructing infiltration basins, to essentially “bank” water underground to be used later for drinking or irrigation. Freshwater’s primary role will be to communicate with state agency personnel, tribes, legislators and other stakeholders – and to make policy recommendations that would allow managed aquifer recharge to be more easily implemented in the future.

Groundwater Governance - Report Cover

Groundwater Governance, Well Cobbled? (November 2022) Ground water is a crucially important but often overlooked resource in the Great Lakes region. As a common-pool resource, the region's aquifers should have a well-structured set of governing principles to guide their sustainable and equitable use. We ask, “but do they?” Read the full report here.

Nonylphenol sedimentation in riverine lakesNonylphenol & Sedimentation History in Riverine Lakes, Twin Cities Metropolitan Area, Minnesota (July 2021)

This study was designed to investigate the occurrence in the environment of a class of compounds, Nonylphenol and many nonylphenol ethoxylates that have been used since the 1940s as detergents and surfactants, among other things. They are known endocrine disruptors and can be produced in wastewater treatment plants. The goal was to document the current concentrations of NP and NPEs within the Twin Cities’ metropolitan watershed and assess how they have changed over time. Read the full report.

Cover of report with historic sinkhole photoHennepin County Bedrock Collapse Project (July 2021)

The County will use results of this investigation to highlight risk to the public, similar to their landslide atlas, allowing stakeholders to take action to mitigate that risk. Read the full report.

Freshwater Water Conservation Advisor Training report

Water Conservation Advisor Training report on year 4 (July, 2020–June, 2021)

The goal of this project is to create a Water Conservation Advisor education and
training program to train a corps of Minnesota Water Stewards and other master level
volunteers who specialize in water conservation best practices. Trained Water
Conservation Advisors will be equipped to educate and engage both individuals and
local community groups—including neighbors, homeowner associations, schools,
churches, businesses, and others—in water conservation practices and complete
projects that enhance groundwater protection.

This report is a project update and final report. Read the full report.

Banking Groundwater: Managed Aquifer Recharge (February 2021) addresses the issue of the more than 75% of Minnesotans who rely on groundwater and 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. This study examined four different kinds of aquifers across Minnesota with unique pressures to determine their suitability for ASR. Read an executive summary or the full report.

Protecting Minnesota's Groundwater: Building Knowledge and Capacity for Groundwater Protection in Local Water Resource Practitioners (June 2019)

Minnesota’s focus on developing comprehensive watershed management plans through the One Watershed, One Plan (1W1P) program requires that local units of government (LGUs), such as soil and water conservation districts (SWCDs) include groundwater protection in local water planning. However, technical field staff and local elected officials need more tools to help them learn about local groundwater, solve local groundwater challenges, and communicate and work effectively with landowners.

Groundwater and Agriculture: Insights From Farmers In Central Minnesota on How to Protect Both (2018)Groundwater and Agriculture: Insights From Farmers In Central Minnesota on How to Protect Both
In agricultural areas with groundwater that is highly sensitive to pollution and surface water resources that are sensitive to groundwater withdrawal, farmers are under pressure from government agencies and environmental groups to improve their on-farm management practices (Kennedy 2015a, 2015b; Marcotty 2012). One area where conflicts over groundwater and agriculture are growing is the central sands region of Minnesota, United States (Gunderson 2014; Haugen 2014; Marcotty 2013; Robertson 2009; Vogel 2014b).
