WATER INDUSTRY FEATURES, INSIGHTS, AND ANALYSIS

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.
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.
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.
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.
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.
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.
