How to start tackling your home’s water and climate footprint Tik Root (Michael Parking for The Washington Post) In 2014, engineer Shahzeen Attari asked 457 university students to draw a picture of how they thought water reached the taps in their homes, and where it went after that. Nearly a third of the diagrams missed the water treatment plant, and almost two-thirds forgot the wastewater treatment plant. On one, the pipes going into the house were labeled “magic.” Most of the time it
does feel like magic. But Attari, an associate professor at Indiana University who studies the psychology behind energy use, wants to see a better public understanding of the mechanics behind the mystique. “If you don’t understand it, you might not value it,” she says. “And if you don’t value it, you might not understand why it’s important to conserve.” How our brains make it hard to solve climate change

Environmental engineering firm Brown and Caldwell (Walnut Creek, Calif.) has been granted funding from The Water Research Foundation (WRF) to study the fate of per- and polyfluoroalkyl substances (PFAS) through sewage sludge incineration.
Thermal treatment of PFAS-laden wastewater solids through sewage sludge incinerators (SSIs) offers a potential PFAS control strategy; however, with few published research studies available, the ability of SSIs to fully mineralize PFAS is unknown.

To this end, a research team led by co-principal investigators Lloyd Winchell (Brown and Caldwell) and Dr. Detlef Knappe (North Carolina State University) has been awarded a $100,000 grant from WRF through its Tailored Collaboration Program to support utility-specific/regional issues. The study aims to explain the fate of PFAS compounds through SSIs and provide utilities with an indication of the extent to which SSIs can eliminate or r

Water touches virtually every aspect of human society, and all life on earth requires it. Yet, fresh, clean water is becoming increasingly scarce one in eight people on the planet lack access to clean water.
Drivers of freshwater salt pollution such as de-icers on roads and parking lots, water softeners, and wastewater and industrial discharges further threaten freshwater ecosystem health and human water security.
The Microplastics And PFAS Connection
By Cayla Cook and Eva Steinle-Darling
Microplastics, small plastic particles with sizes ranging from 5 millimeters to 1 nanometer with various morphologies such as microfibers, fragments, pellets (nurdles), or microbeads, have received increasing attention, including upcoming statewide monitoring in California.
Per- and Polyfluoroalkyl Substances (PFAS) are a group of unique chemically stable compounds and, as a result, have made them highly valuable across a wide range of industrial, commercial, and military uses. However, this feature concomitantly makes them recalcitrant and persistent in nature thus coined “forever” chemicals (Lindstrom et al. 2011, Buck et al. 2011). Recent developments in toxicology, coupled with significant political pressure, have put PFAS on the fast-track for regulation in drinking water and wastewater. While co-occurrence is well-known for a variety of contaminants like triclosan and triclocarban, the connecti
