    According to the latest Intergovernmental Panel on Climate Change Report, the world is getting warmer, and in the western United States, that translates into drought and significantly increased wildfire activity. In September 2020, western Oregon experienced unprecedented wildfires that dramatically affected people’s lives, infrastructure, and the environment, and impacted drinking water sources.

  • Lake Stratification And Nanobubble Generators

    If you’ve ever jumped in a lake during the summer and felt warmer water on the surface and as you sunk deeper, you felt the cooler water at the bottom, you experienced the effects of thermal stratification. Though this is natural, imagine you go to jump in the lake and it has a thick layer of algae growing and it smells. Would you still jump in?

  • Impact Of Congressional Ruling On PFAS

    The ability of per- and polyfluoroalkyl substances (PFAS) to contaminate everything in their wake and resist degradation in nature has propelled these “forever chemicals” into a serious public health concern over the past two decades, galvanizing calls for sweeping federal legislation.

  • Temporary Bypass Helps City Of Auburn, New York, Divert Stream Water Safely And Efficiently

    The Owasco Outlet in Auburn, New York, is a waterway that flows from the north end of Owasco Lake through five counties before connecting to the Seneca River. Over time, portions of the Owasco Outlet were contaminated with coal tar. A byproduct of burning coal, the coal tar had been buried throughout the grounds of a former manufactured gas plant located along the waterway during the 1800s, eventually leaching into the surrounding sediment.

  • The Ocean Is Full Of Tiny Plastic Particles — We Found A Way To Track Them With Satellites

    Plastic is the most common type of debris floating in the world’s oceans. Waves and sunlight break much of it down into smaller particles called microplastics — fragments less than 5 millimeters across, roughly the size of a sesame seed. To understand how microplastic pollution is affecting the ocean, scientists need to know how much is there and where it is accumulating. Most data on microplastic concentrations comes from commercial and research ships that tow plankton nets — long, cone-shaped nets with very fine mesh designed for collecting marine microorganisms.

  • We’re talking marketing this spring, and there’s a really good reason for that. Business as usual is now business unusual, and when we come out of the pandemic and all the economic and social fallout, you still want to be in business. In fact, now you can see the value of not just scraping by every month – you need to be built to last. The only way to make sure you’re built to last is to master marketing. Deep down you know this – no matter how good your service is, if nobody knows about it, you don’t make money. So let’s talk first about word of mouth, because for some MSPs, it’s the only tool in their marketing toolbox. But even for the best MSPs, it’s one of the most important.

  • Both direct and indirect potable reuse have massive potential to address growing water scarcity issues.
