• 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.
• PFAS In Pregnant Women's Drinking Water Puts Their Babies At Higher Risk, Study Finds

  When pregnant women drink water that comes from wells downstream of sites contaminated with PFAS, known as “forever chemicals,” the risks to their babies’ health substantially increase, a new study found. These risks include the chance of low birth weight, preterm birth, and infant mortality.

• PFAS Settlements: Debunking The Myths And Revealing What's Really At Stake For Water Utilities Misinformation and confusion could prevent some utilities from benefitting from the aqueous film-forming foam multidistrict litigation (AFFF MDL) settlements. Here are five common myths about the AFFF MDL PFAS settlements and how public water systems can make the most of this unprecedented funding opportunity.
• When Chemistry Meets Water Innovation

  Nobel-winning molecular materials are poised to reinvent purification, desalination, and reuse.

• Solving The World's Microplastics Problem: 4 Solutions Cities And States Are Trying After Global Treaty Talks Collapsed

  Microplastics seem to be everywhere — in the air we breathe, the water we drink, the food we eat. Countries have tried for the past few years to write a global plastics treaty that might reduce human exposure, but the latest negotiations collapsed in August 2025. While U.S. and global solutions seem far off, policies to limit harm from microplastics are gaining traction at the state and local levels.

• AEC System Proven Effective For Chloride Removal

  In two bench-scale tests, a new technology effectively removed up to 99% of chlorides and 97% of total dissolved solids in a single pass. This solution offers a commercially viable alternative to traditional treatment methods.

• Common Misconceptions Are Keeping Lakes "Sick"

  Long-held misconceptions about lake management fuel the intensity and recurrence of harmful algal blooms.

• Colorado's Subalpine Wetlands May Be Producing A Toxic Form Of Mercury — That's A Concern For Downstream Water Supplies

  The wetlands found across the Rocky Mountains of Colorado just below tree line are crucial for regulating the supply of clean water from the highlands to metropolitan regions downslope, including Denver. However, new research shows the wetlands also harbor a health risk.

• Grand Canyon's Dragon Bravo Megafire Shows The Growing Wildfire Threat To Water Systems

  As wildfire crews battled the Dragon Bravo Fire on the Grand Canyon’s North Rim in July 2025, the air turned toxic. A chlorine gas leak had erupted from the park’s water treatment facility as the building burned, forcing firefighters to pull back. The water treatment facility is part of a system that draws water from a fragile spring. The fire also damaged some of the area’s water pipes and equipment.
