The Enzyme Bottleneck: Why Conventional Lake Management Is Failing — And What The Science Says About Genuine Bio-Dredging For decades, the dominant framework for assessing and managing lake health has been built around surface water measurements: chlorophyll-a, total phosphorus, water clarity, and the composite Trophic State Index derived from them. These metrics are familiar, standardized, and widely accepted. They are also, according to a growing body of peer-reviewed literature, measuring the wrong part of the lake.

Drinking Water Contaminated With 'Forever Chemicals' During Pregnancy Linked To An Increased Risk Of Childhood Asthma
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?
VIEWS ON THE LATEST REGS
