Center for Water Policy Director, Professor, and Lynde B. Uihlein Endowed Chair Melissa Scanlan was on NPR’s High Plains Public Radio discussing a proposed rural Kansas data center. Professor Scanlan contextualized how the lack of resource demand disclosure and regional- and state-level planning for AI-data center development can disempower local communities.

Massive data centers powering artificial intelligence have sprouted across the country in recent years, drawing opposition for their water consumption. But in rural Kansas, boosters of one project argue that it could represent a huge savings in water use compared to irrigated farming.

Walking on the beach is a simple, yet legally complex act.

The Public Trust Doctrine guides how we access, use, and enjoy certain water bodies. However, states differently interpret and apply certain tenets of this doctrine, including whether and where the public can walk the shoreline. Director, Professor, and Lynde B. Uihlein Endowed Chair Melissa Scanlan and Water Science and Policy Communications Fellow Will Matuska write in The Conversation US about the ways the public is excluded from reaching the water’s edge — even when that right is protected by the public trust — and how communities respond.

Both legally and practically speaking, getting to the water’s edge isn’t as straightforward as it might seem – or as many people might like.

Shorelines and beaches are rapidly shifting and eroding as climate change causes ocean levels to rise and Great Lakes water levels to wildly fluctuate. But the most common responses to this erosion, specifically hard shoreline armoring and beach nourishment, raise serious concerns regarding access to public trust resources.

In the Center for Water Policy’s latest research, Water Policy Specialist Emma Ehrlich (2024-2025), Interim Assistant Director Cora Sutherland (2024-2025), and Director Melissa Scanlan investigate the legal protections for public access along the oceans and Great Lakes. This published academic research sheds light on the legal gaps in climate-disrupted shoreline management and highlights the need for Great Lakes states to learn from exemplar states to better protect public access to our beaches.

Quick Facts: What you need to know

🔹 Shoreline armoring can physically restrict public access and diminish our sandy beaches.

🔹 Government-funded beach nourishment often sparks debate over whether public funds are disproportionately benefiting private homeowners.

🔹 Legal gaps exist where courts’ interpretations of public access requirements reveal significant deficiencies and a lack of protective policies across different regions.

Wisconsin isn’t the only Great Lakes state grappling with the complex issue of abandoned boats. The G Tug Hawaii has been submerged in Presque Isle Bay, Lake Erie, since December 2025. On May 8, a crane attempted to remove the boat from the bay but failed and dropped the tug back into the water.

On May 8, the G Tug Hawaii was scheduled to be pulled out of Lake Erie. A sudden mishap caused the boat to sink back to the bottom of the bay.

A recent report from the state of Michigan shows that its phosphorus input into Lake Erie has decreased. The report highlights community environmental programs, improvements to wastewater treatment plants, and new sensing technology as crucial parts of Michigan’s phosphorus reduction plan. However, reducing phosphorus loading in Lake Erie is a collaborative issue, and Michigan’s phosphorus reductions can be offset by high phosphorus inputs from Ohio or Ontario. The U.S. and Canada aim to reduce total phosphorus inputs into western Lake Erie by 40%.

Milwaukee is facing a federal deadline to replace all lead pipes by 2037 — an uphill task. Since 2017, Milwaukee has taken advantage of funds from the Bipartisan Infrastructure Law to subsidize the cost of replacing more than 10,000 lead pipes with copper, but more than 65,000 lead pipes remain. Reaching that goal may be more challenging due to federal funding constraints.

Milwaukee is facing a federal deadline for replacing lead service lines that carry water from mains to homes. The city might not meet it.

The U.S. Environmental Protection Agency ("EPA") has started a rulemaking process to rescind certain PFAS drinking water standards. PFAS are a large class of “forever chemicals” that pose a suite of environmental and public health risks.

Current standards, established in 2024, set maximum contaminant levels for certain types of PFAS in drinking water. EPA is proposing to rescind those standards for four PFAS compounds. Before changing the PFAS standards, EPA must hold a public comment period, which is open until July 20, 2026.

Learn more about the proposed change and participate in the public comment period: https://www.federalregister.gov/documents/2026/05/20/2026-10085/rescission-of-regulatory-determinations-and-removal-of-related-provisions-for-four-pfas-substances

The water demands of AI-data centers continue generating questions and concerns, not just in the U.S. but internationally. Center for Water Policy Assistant Director Tressie Kamp was quoted in the French publication Franceinfo about looking toward the future resource demands of our AI use and the associated resource demands of AI-data centers.

“If we are to believe [data that we’re seeing], the use of AI will continue to grow almost infinitely,” Kamp said. “So the right question to ask is rather: What lies ahead for us in terms of water consumption if we continue at this pace?”
