WATER INDUSTRY FEATURES, INSIGHTS, AND ANALYSIS

Drinking Water Contaminated With 'Forever Chemicals' During Pregnancy Linked To An Increased Risk Of Childhood Asthma — New Study While most of us are routinely exposed to low levels of PFAS, some communities are exposed to far higher levels from nearby pollution sources. A new study shows that in one of these at-risk communities, children were more likely to develop asthma if their mothers were exposed to very high PFAS levels during pregnancy.
The Pragmatic Shift In Source Water Protection: Moving From Symptom Management To Root-Cause Accountability A shift in how we approach source water protection is long overdue. Currently, we are trapped in a cycle of escalating costs, forced to treat symptoms like algae and invasive weeds expediently with chemicals while the underlying risk in the reservoir compounds. True risk management requires breaking this cycle.
The AWWA Said $2.4 Trillion. It Missed The Compound Interest. Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
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.
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.
