02.02.24 -- PFAS Are Being Spread On World's Ski Slopes

PFAS are quickly emerging into a major environmental and human health concern. Characterized by their extreme resistance to breaking down, PFAS are persistent in the environment and can be found in water, wastewater, soils, air, food, and in the blood of humans and animals.

When high levels of arsenic were found in the drinking water in the community of Alto Lampa outside of Santiago de Chile, municipal water provider Aguas Adinas faced a predicament. AdEdge Water Technologies was contacted to design a treatment approach. This case study describes how iron oxide adsorption helped Alto Lampa reduce arsenic levels in treated water to non-detectable concentrations.

Water utility managers have a lot of responsibilities, not the least of which is to keep up with the latest in the industry — especially contaminants like PFAS. Water Online spoke with Calgon Carbon about these important emerging contaminants and how best to remove them.

Non-revenue water (NRW) and other information gaps that have significant impact on operating costs are causing many water distribution utilities to seek affordable ways to gain greater insight into flow data. In this Q&A, Barry Spiegel of McCrometer describes how full-profile insertion (FPI) electromagnetic flow meters (mag meters) can provide relief, without breaking the bank.

Aqua Pennsylvania (Aqua PA), an Aqua America subsidiary, serves more than 1.4 million people in 32 counties across Pennsylvania. Aqua PA has significant experience using chloramine chemistry to mitigate trihalomethane (THM) disinfection byproduct formation in its many distribution systems.

Deron Austin, director of water management solutions at Mueller Water Products, discusses pressure management technologies for water distribution systems during the Water Online Virtual Water Expo.

After researching different ozone systems, plant officials at a 12-MGD wastewater plant in Arkansas chose to install BlueInGreen’s HyDOZ technology in order to more efficiently meet current permit requirements, as well as prepare for future legislation.

Panama City Beach is situated on 27 miles of white-sand beaches in the panhandle of northwest Florida. The city is ecologically significant in that it is surrounded by thousands of acres of protected wetlands that are part of the West Bay Ecosystem. 

City staff were looking for an idea to remedy the logistical issues in the Tarpon Springs Wastewater Treatment Plant located in Pinellas County, an area known for being a small Greek community on Florida’s Gulf Coast.

There’s a lot of buzz these days around the digital transformation of “this” and the digital transformation of “that” — but what does it actually mean in practice, and specifically for the water sector?

From the largest metropolitan water treatment plant (WTP) or wastewater treatment plant (WWTP) operations to the smallest rural systems, the goals are essentially the same — achieve regulatory compliance and the most efficient results at the lowest practical cost. Here are several high-level guidelines to achieving a common strategy that works across virtually all applications.

For over 40 years, the Clean Water Act (CWA) has been a primary force protecting our waters and dictating the work of treat­ment professionals. And, for just as long, samplers have been the tools that allow this work to be carried out. To help usher those plants into the modern age, Water Online spoke with Endress+Hauser about how samplers have evolved to meet changing needs.
