• Putting The National Toxicology Program's Fluoride Review In Context

  Despite renewed public concern over fluoride and cognition, the National Toxicology Program’s findings focus on high‑fluoride groundwater conditions — not the controlled levels used in U.S. drinking water systems. Understanding that distinction is critical for utilities navigating policy questions and community expectations.

• Opinion: Why PFAS Policymakers Should Read Past The Abstract

  When it comes to drinking water, sound public policy requires sound scientific research. Publication in a prestigious, peer-reviewed journal helps establish legitimacy for scientific claims in public discourse. But science is a social process, scientific standards of evidence vary across disciplines, and peer review does not guarantee validity. For readers who stop at the abstract, these distinctions can be easy to miss.

• Reclaiming Water From Contaminated Brine Can Increase Water Supply And Reduce Environmental Harm

  People around the globe are trying to figure out how to save, conserve, and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater. But for all the clean water they may produce, those processes leave behind a type of liquid called brine. I’m working on getting the water out of that potential source, too.
• L.A.'s Terminal Island Water Reclamation Plant Leverages Water Reuse To Protect Groundwater Supply

  In this article, Lance Thibodeaux, division manager for the Terminal Island water reclamation division at LA Sanitation and Environment, describes Terminal Island’s industry leading water reuse program and its long-time partnership with Xylem.

• Planting The Seeds Of Inspiration: Eelgrass Restoration

  Restoring eelgrass beds is critical because they provide habitat for many kinds of marine life, improve water quality by filtering out pollution, and the plant’s root system stabilizes the sediment on the seafloor, protecting shorelines from erosion.

• Using Biological Competition To Suppress Algae Growth

  Effective algae control shifts the focus from removal to nutrient management. By leveraging bioaugmentation to outcompete algae for nitrogen and phosphorus, facilities can stabilize pH levels and dissolved oxygen, ensuring long-term pond clarity and consistent wastewater treatment performance.

• PFAS Are Turning Up In The Great Lakes, Putting Water Supplies At Risk — Here's How They Get There

  No matter where you live in the U.S., you have likely seen headlines about PFAS being detected in everything from drinking water to fish to milk to human bodies. Now, PFAS are posing a threat to the Great Lakes, one of America’s most vital water resources.
• Oilfield Pollution In West Texas: Engineering Lessons For Groundwater Protection And Advanced Oxidation

  Legacy oilfield contamination requires advanced strategies to protect vital groundwater. Explore the technical challenges of subsurface remediation and how advanced oxidation processes provide a more effective pathway for destroying persistent hydrocarbons and restoring aquifer quality.

• Why Too Much Phosphorus In America's Farmland Is Polluting The Country's Water

  When people think about agricultural pollution, they often picture what is easy to see: fertilizer spreaders crossing fields or muddy runoff after a heavy storm. However, a much more significant threat is quietly and invisibly building in the ground.
• Water In 2026: The Nexus Of Policy, Technology, And Resilience

  As water systems become more circular and complex, understanding and managing the subsurface — the hidden half of the water cycle — is becoming a critical enabler of resilience. This article explores the key trends shaping this new reality, from tackling “forever chemicals” to the water strategies redefining heavy industry.
