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.
What Are Legionella Log Books And Why Are They Important? Implementing and managing a Legionella control regime can sometimes seem daunting and complex. Invariably, a lot of resources, time, and effort are needed to achieve the required standard and provide assurance to senior management and auditors that controls are effective and those that are not are being managed and rectified appropriately.
How ABB's Flow And Digital Technologies Help Bawat With Smarter Ballast Water Compliance
The International Maritime Organization (IMO) sets strict global standards for ballast water management to prevent the spread of harmful aquatic organisms. For companies like Bawat, a Danish innovator in ballast water management, being able to verify ballast water flow measurements quickly, accurately, and from anywhere in the world is essential.
PFAS Policy In 2025: Why It's Time To Go Beyond Remediation The most common techniques for disposing of PFAS may no longer be good enough.
The Uneven Fight Against PFAS In Rural vs. Urban Water Systems Drinking water systems across America face a mounting PFAS threat with starkly different capacities to respond. Large urban utilities typically have ample resources to detect and remove these persistent chemicals from water supplies, while small rural systems operate with tight budgets, skeleton crews, and minimal technical support.
CERCLA And PFAS: What's The Liability For Water And Wastewater Utilities? Federal rules aim to target those liable but may miss the mark. Utilities can redirect the effort — and costs — to those truly responsible for PFAS contamination.
25 Years Of Everglades Restoration Has Improved Drinking Water For Millions In Florida, But A New Risk Is Rising
As the Everglades has shrunk over the past century, South Florida’s water supply and water quality have become increasingly threatened, including by harmful algal blooms fueled by agriculture runoff. Now, the water supply faces another rising challenge: saltwater intrusion.
From Symptoms To Solutions: Measuring What Matters To Transform Reservoir Risk Management A new methodology for measuring "what truly matters" empowers reservoir managers to make informed, proactive decisions that break the cycle of lake degradation and secure long-term water quality and ecosystem health.
A Paradigm Shift In Reservoir Management
Reservoir managers are utilizing a risk management framework along with innovative metrics to address the root causes of lake degradation, including eutrophication, hypoxia, and harmful algal blooms.

A Tiny Bit Of PFAS

In the most recent edition of Water Innovations, there is not a single article focused on PFAS. That wouldn't be exceptional if not for the fact that discussion around per- and polyfluoroalkyl substances has so thoroughly dominated the water space lately. And yet, I penned this as an intro to the edition — just "a tiny bit of PFAS" content — because a small portion of PFAS is of the utmost importance in terms of treatment, policy, and cost.
How CERCLA Complicates The PFAS Problem

As states and the federal government attempt to crack down on the proliferation of PFAS and their health consequences with a spate of new regulations, there is one significant upcoming ruling that will have tremendous impact for compliance and costs: the final rule on PFAS CERCLA designation.
