• Why Colorado River Negotiations Stalled, And How They Could Resume With The Possibility Of Agreement

  The five most common sources of conflict between people are values, data, relationships, interests, and structure. The current Colorado River negotiations include all five.

• Designing Resilient PFAS Treatment Strategies For Water Agencies

  Water agencies across the U.S. are facing a rapidly evolving regulatory landscape for per- and polyfluoroalkyl substances (PFAS) that poses a conundrum: Should they take a cautious or aggressive approach to treating PFAS contamination in their water system?

• The Future Of In Situ Chemical Oxidation For Targeted Solvent Destruction

  The U.S. EPA’s 2026 trichloroethylene (TCE) compliance deadlines are now forcing a concrete shift toward source-zone destruction. In situ chemical oxidation (ISCO), sequenced with enhanced bioremediation, is proving to be the most credible path to groundwater contaminant rebound mitigation.

• When Drinking Water Raises Bigger Questions About Brain Health And Environmental Risk

  A new study linking certain groundwater sources to higher Parkinson’s risk underscores a broader question for the water sector: how environmental exposures in drinking water may influence long-term health.
• From Compliance To Circularity: Rethinking Chromium Management In Chrome Tanning

  In an industrial landscape increasingly shaped by lifecycle accountability, material traceability, and rising disposal costs, chromium recovery is not merely a technical alternative — it is a strategic upgrade, where wastewater can become a resource stream.
• Extreme Weather Is Transforming The World's Rivers. We Need New Ways To Protect Them

  Around the world, rivers are no longer changing gradually. Rather, they are being increasingly transformed by extreme climatic events such as floods, droughts, and heatwaves. A newly published global review finds these events are pushing ecosystems beyond their limits and eroding biodiversity and core functions.
• EPA Seeks Court‑Ordered Removal Of 4 PFAS Limits

  The U.S. EPA is testing a new procedural strategy to remove four PFAS drinking‑water limits from ongoing litigation, asking the D.C. Circuit Court of Appeals to invalidate those limits on the grounds that the EPA itself committed a procedural misstep when issuing the 2024 PFAS rule.
• Innovative Water Reuse Solutions With Xylem's Advanced Treatment Technology

  Transitioning to advanced purification methods like UV-hypochlorite oxidation allows municipalities to secure reliable, local water supplies. These strategies mitigate drought risks and protect coastal environments by transforming wastewater into a high-quality resource for reuse.

• Produced Water Treatment Market: The Next Big Wave In Industrial Sustainability

  With the rise of water scarcity, environmental regulations, and corporate sustainability mandates, produced water treatment has become a strategic imperative for industries far beyond oil and gas. It is one of the fastest-growing segments in the water treatment industry, which has emerged as an amalgamation of environmental stewardship, regulatory compliance, and technological innovation.
• 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.
