New Report: What Utilities Need to Know About Iranian Cyber Threats

Recent geopolitical tensions are driving increased cyber activity by Iranian‑linked threat actors, and water and wastewater utilities remain a key target. A new WaterISAC report breaks down the repeatable tactics these actors use to gain access, stay hidden, and cause disruption. This is often accomplished by exploiting weak credentials, using phishing emails, and taking advantage of unpatched systems rather than through sophisticated malware.


The report highlights how attackers increasingly abuse legitimate tools, cloud services, and trusted access to blend into normal operations, with a growing emphasis on identity‑based attacks and large‑scale disruptive campaigns. It also outlines practical, utility‑focused mitigations aligned with WaterISAC’s 12 Fundamentals to help organizations reduce risk right now.


Read the full report for a deeper look at real‑world tactics, recent incidents, and clear steps utilities can take to strengthen their defenses.

U.S. EPA seeks public feedback on water affordability tool

The U.S. Environmental Protection Agency (EPA) is asking for public input on its Clean Water Act Financial Capability Assessment (FCA) guidance. This an important resource that helps water bills remain affordable during infrastructure upgrades within wastewater systems. EPA will use the public feedback to update this guidance to reflect the ability of rate payers to financially support these upgrades while also considering the potential impacts for rural communities.


"The guidance provides information on how to assess a community’s financial capability as part of negotiating implementation schedules under both permits and enforcement agreements. In addition, the guidance identifies specific ways to consider economic impacts to public entities when determining water quality standards variances and during antidegradation reviews."


After reviewing input from the public, EPA will consider revisions to the guidance in order to address public concerns as part of its ongoing commitment to working with communities to protect human health and ensure practical implementation.


EPA plans to hold two virtual meetings to discuss the guidance before the public comment period closes.


EPA will accept comments through May 26, 2026, via the Federal eRulemaking portal, referencing Docket ID No. EPA-HQ-OW-2026-1090.

A New Strategy: Water Is National Security

A New Strategy: Water Is National Security

waterloop


"Water is emerging as a defining factor in U.S. economic growth and national security—from where data centers and energy projects can scale to how communities absorb the rising costs of floods, droughts, and insurance risk. 


In response, a new Aspen National Water Strategy has been released, laying out a plan to rethink how the country manages water. This episode is a conversation with the co-leads for developing the strategy, Martin Doyle of Duke University and Newsha Ajami of Lawrence Berkeley National Laboratory.


Their central argument is a shift in framing: water is not just an environmental or local utility issue—it’s a core economic input and a strategic asset. 


The conversation explores how that plays out today, from AI and energy demands tied to water availability to insurers effectively redrawing the map of risk across the country. It also gets into what’s holding the system back, including fragmented governance, outdated infrastructure models, and policies that don’t align with how water actually moves through watersheds.


The strategy outlines priorities including governing for outcomes instead of process, investing in rural landscapes that underpin national water supply, and expanding infrastructure to include natural systems, data, and people. 


Doyle and Ajami also highlight the need to remove barriers to adopting solutions that already exist, and to rethink financing and business models so innovation can scale. It’s a clear-eyed look at how water is shaping the economy and risk landscape today—and what it will take to treat it as the national priority it has become."

Tell Me More—Removing lead pipes, how Minnesota protects drinking water

Tell Me More—Removing lead pipes, how Minnesota protects drinking water

Conservation Minnesota


"There is no safe level of lead consumption, and lead service lines remain a persistent threat to Minnesota communities. In 2023, the state legislature passed the Lead Service Line Replacement Bill, that set a goal to replace all lead water service lines by 2033 and approved an initial $240 million to begin the work. That money has now been allocated, and more funding is needed to keep us on track to achieve the goal.


Check out [this] panel discussion with Representative Sydney Jordan, Moorhead Mayor Shelly Carlson, and Brent Marsolek, Lead Free Project Manager with St. Paul Regional Water Services, about what work has been done so far and what still needs to happen to ensure lead-free water in Minnesota."
