From Warning To Reality: Lessons From The Latest OT Attacks On Water Utilities
On July 10, I published an article warning that water and wastewater utilities had become prime targets for state-sponsored cyber actors, describing how attackers exploit internet-exposed PLCs, how the IT/OT divide leaves organizations vulnerable, and why the sector needed to act before an incident forced their hand. Today, that scenario is no longer hypothetical.  Continue Reading..

Advanced Water Treatment Strategies Help Data Centers Manage Cooling Water At Industrial Scale
Data centers are evolving into industrial-scale thermal-management facilities as artificial intelligence (AI), high-performance computing (HPC), cloud platforms, and accelerated computing increase rack power density. Modern AI racks can exceed 50–120 kW per rack, creating substantially higher heat-rejection requirements than conventional enterprise infrastructure. ASHRAE's (American Society of Heating, Refrigerating and...  Continue Reading..

How To Manage Warm-Season Biological Upsets In Wastewater Lagoons
The rate of biological activity in a treatment lagoon is largely a function of water temperature. Once the water rises above roughly 59 °F (15 °C), metabolic rates increase across the entire microbial and invertebrate community.  Continue Reading..

Colorado River Water Conservation Efforts Get Only Halfway To A Solution
In August 2026 the nation’s two largest reservoirs, Lake Mead and Lake Powell, both on the Colorado River, hit their lowest levels since they first began to be filled in 1936 and 1963, respectively. The federal government and the seven Colorado River basin states have been unable to reach an agreement about who should reduce water usage by how much to avoid catastrophic declines in lake levels.  Continue Reading..

Sample Collection And Storage: Protecting Water Quality Results From The Start
Flawless analytical procedures mean little if samples are compromised before testing. Discover how proper container selection, representative collection techniques, and rigorous preservation protocols prevent pre-analysis error to ensure defensible, accurate water quality results.  Continue Reading..

Reverse Osmosis Gets Smarter: New Technologies Target Energy Use And Membrane Fouling
Nearly 45–60% of a reverse osmosis (RO) plant's operating cost is linked to energy consumption, while membrane fouling can reduce productivity by 15–40% and increase cleaning costs by thousands of dollars annually. The newest generation of RO systems is therefore focused on reducing energy demand, extending membrane life, and using intelligent monitoring to predict fouling before performance declines.  Continue Reading..

U.S. Federal Water Funding "Cliff" Masks Four Distinct Timelines And Uneven State Exposure

Federal water infrastructure funding in the United States is set to fall roughly 63% between fiscal year 2026 and fiscal year 2027, dropping from US$23.4 billion to an estimated US$8.6 billion. But according to new analysis from Bluefield Research, a leading provider of global water market data and insights, the story behind this anticipated decline is more nuanced than the headline suggests.

Emerging Contaminants Follow Distinct Rules When Partitioning Between Sediment And Water, Study Finds

For decades, environmental scientists have struggled to predict where emerging contaminants end up in rivers—whether they linger in sediments or remain mobile in the water. That uncertainty has made risk assessment difficult and management decisions unreliable.

Even Protected Florida Wetlands Can't Escape Microplastic Pollution

Microplastics are turning up almost everywhere – from oceans and rivers to soils and sediments – yet far less is known about what happens when they enter freshwater wetlands. Often overlooked in favor of marine and coastal environments, wetlands can act as both pathways and traps for microplastics, potentially capturing and retaining pollution.

Global Initiative Will Harness Wastewater As An Early Warning System For Public Health Protection

Labs across the world will collect wastewater samples on Global Wastewater Day in 2027 to generate a unique snapshot of international public health.

Catalyzing The Community: Chemists, Navajo Leaders Educate On Clean Water

By pairing water quality research with community engagement, scientists and tribal leaders help residents identify safe drinking water sources.

Mountain Hayfields Can Filter Nutrients And Support Clean Water

Irrigated mountain hayfields can act as large filtration systems that reduce sediment, phosphorus and other contaminants from runoff, sometimes improving the quality of water flowing back into the environment, Colorado State University research has found.
