Center for Water Policy Quoted in Washington PostStoryCovering U.N. Report on Global Water ‘Bankruptcy’

Center for Water Policy Director, Professor, and Lynde B. Uihlein Endowed Chair Melissa Scanlan was quoted in aWashington Postarticle examining arecent report from the United Nations University, the U.N.’s research arm,thatfindsclimate change, pollution and decades of overuse have pushed the world into a state of “water bankruptcy,”a state they define as a long-term condition that requires a global reset in approaches.

Fresh water is a finite resource with inputs and outputs that make up a global water budget. People worldwide are starting to experience the impacts of overspending that budget. “The global scope of the report is useful in showing repeat patterns,” Scanlan said. “It’s not just the Southern Hemisphere, it’s not just the Middle East. There is something larger at play in terms of how we’re treating water across the world.” Professor Scanlan’s water law and policy research has included analysis of water budget issues closer to home, highlighting how climate change and population pressures have intensified water management challenges in the relatively water-rich North American Great Lakes.

Center for Water Policy Assistant Director Tressie Kamp featured in“Door County Knock”on abandoned boats

Center for Water Policy Assistant Director Tressie Kamp was featured in a “Door County Knock” article about the fate of the abandoned Donny S. tugboat, increasingly entrenched in Baileys Harbor, Wisconsin, after remaining unmoved since fall 2021.  

Law enforcement issued the owner of the tug citations totaling tens of thousands of dollars, but the owner is without means to remove the vessel. A navigation and safety hazard, the boat also could pose a risk to the environment if harmful liquids are released into surrounding waters. 

Kamp explains in the article the authority of various government entities to remove the Donny S., but states that “a lack of any clear mandate for government action further complicates the problem of removal.” The Center recommended more clear and efficient solutions to the issue of abandoned boats in Wisconsin, the Great Lakes, and beyond, in a summer 2025 policy brief, around the same time the Wisconsin Legislature started considering related  to try and address the issue.

Milwaukee Journal Sentinel Story on Shorewood Beach Walking Case That Could Define Public Shoreline Access

Center for Water Policy Director, Professor, and Lynde B. Uihlein Endowed Chair Melissa Scanlan was quoted in a recent Milwaukee Journal Sentinel article examining a municipal court trial about whether people have the right to walk along Lake Michigan’s shoreline below the ordinary high-water mark. The case centers on Shorewood resident Paul Florsheim, who is contesting a trespassing ticket he received while walking along what he understood to be publicly accessible beach. Florsheim argues that Wisconsin’s Public Trust Doctrine guarantees the public’s right to traverse the area between the water’s edge and the ordinary high-water mark. His father, Thomas Florsheim, testified that when he was a riparian owner along this same beach until 2003, he viewed the beach as “common property” and believed that the vegetation marked the start of private land. 

Professor Scanlan noted that while Wisconsin has never litigated this question for its Great Lakes coasts, both Michigan and Indiana’s supreme courts have upheld the public’s right to walk along Great Lakes shorelines. She emphasized that Wisconsin now has an opportunity to clarify and potentially affirm this historic public access tradition.

W51StoryonLake MichiganBeach AccessDraws on Center for Water Policy Research

Center for Water Policy Director, Professor, and Lynde B. Uihlein Endowed Chair Melissa Scanlan was quoted in a recent W51 story about public access to Wisconsin’s Great Lakes beaches. In summer 2025, the Village of Shorewood police issued resident Paul Florsheim a ticket for trespassing when walking the shoreline of Lake Michigan on what he viewed as “the public part” of the beach. Florsheim is challenging the ticket in municipal court, arguing that he was walking below the ordinary high-water mark and exercising his Wisconsin Constitutional rights under the Public Trust Doctrine. 

Professor Scanlan noted that in the two other Great Lakes states that have considered similar beach walking challenges, the Michigan and Indiana supreme courts ruled that the Public Trust Doctrine protects the public’s right to walk on Great Lakes’ beaches between the water and ordinary high-water mark.

Director Melissa Scanlan Featured on W51 Discussing Need for Great Lakes–Wide Oversight of Data Center Industry Expansion

The Great Lakes Compact is designed to protect surface and groundwater across the Basin, but it does not require direct reporting of water used by data centers that hook up to municipal systems—leaving a disclosure gap as the industry rapidly expands. In recent features on W51 89.7 FM – Milwaukee’s NPR’s “Morning Edition” and “Lake Effect,” Center for Water Policy Director, Professor, and Lynde B. Uihlein Endowed Chair Melissa Scanlan warned that this regulatory gap obscures the significant water and energy demands associated with data center growth. 

Scanlan called for “greater disclosure of what the water needs are and how the centers will be powered” and emphasized that taking a long-term, regional view would give Great Lakes states “more control over their future” as this new industry scales up.

Center for Water Policy Assistant Director Tressie Kamp featured in “Circle of Blue”on wetlands

Center for Water Policy Assistant Director Tressie Kamp was featured in a “Circle of Blue” article on wetlands and the 2025 1,000-year flood in Milwaukee, WI. The article examines how wetlands, “nature’s kidneys,” mitigate flood-related property damage after heavy rain events. The article also highlights wetland restoration sites around southeastern Wisconsin that successfully soaked up flood waters after the historic August 2025 storm. Rollbacks to wetland protections leave these critical ecosystems vulnerable.   

This summer, flooding caused nearly $76 million of damage to both private homes and public sector losses. “In southeast Wisconsin in particular, this issue exemplifies how the protection or lack of protection in an area can impact such a wide swath of stakeholders,” said Kamp.

PFAS Contamination in Wisconsin’s Public Drinking Water Supplies: Regulatory Context

PFAS, a large class of human-made chemicals, continues to present a major public health concern in Wisconsin and beyond. Since the Center published its PFAS policy brief in 2023, the U.S. Environmental Protection Agency (“EPA”) issued an April 2024 final rule establishing drinking water standards—also referred to as MCLs—for six PFAS compounds. EPA signaled in May 2025 an intent to rescind standards for four of those compounds, but no formal rulemaking has begun.

Our updated Policy Brief breaks down the legal context, timelines, and key implications—and offers recommendations for navigating what comes next.
