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, standardised, and widely accepted. They are also, according to a growing body of peer-reviewed literature, measuring the wrong part of the lake.  Continue Reading..

Algae In The Air?

The August Cough is one of several respiratory symptoms that tend to crop up in the area during the summer, when blooms of algae-like critters called cyanobacteria are at their peak. Some symptoms can be severe; in 2014, a seven-year-old girl had an asthma attack and was hospitalized immediately after swimming in a bloom.

AMWA Statement On EPA's Draft Sixth Unregulated Contaminant Monitoring Rule

“AMWA and its member drinking water systems across the country share EPA's commitment to the science-based processes established under the Safe Drinking Water Act (SDWA) for identifying, monitoring, and regulating contaminants that may pose risks to public health. The Unregulated Contaminant Monitoring Rule (UCMR) is an integral part of that framework, helping to collect nationwide data on the occurrence and concentrations of contaminants not currently subject to SDWA regulation.
