The Water Chronicles: A Journey to Understand the World’s Water Disparities

In this episode of Talking Under Water, Co-host Mandy Crispin chats with Kaitlin Spiridellis, a Vanderbilt University Michael B. Keegan traveling fellow. Spiridellis has worked for over three years within Vanderbilt’s Drinking Water Justice Lab and focuses on the disparities in how people experience drinking water in different communities.  In the summer of 2024, she began touring various continents to gain a better understanding of the disparities in how people experience drinking water. In this episode, Crispin and Spiridellis start by discussing her trip to Latin America, and Spiridellis will be writing articles for WaterWorld on her experiences, called World of Water.

U.S. EPA releases PFAS risk assessment: Now what?

In April of 2022, Maine banned land application of biosolids due to concerns of PFAS. It has become a point of contention in the state, causing wastewater systems to scramble for alternatives with much of it going over the border to Canadian landfills as Maine landfills refuse to accept the waste or run into capacity issues. 
Nearly two years later, U.S. EPA released a long-awaited risk assessment of two PFAS chemicals — PFOA and PFOS — in sewage sludge and land-applied biosolids on January 14, 2025. While this assessment is not a regulation, it suggests a degree of risk that could one day include a regulation.  
So what do wastewater leaders need to do now and what does this assessment mean for them? Endeavor Business Media Water Group Editor Alex Cossin caught up with Kyle Thompson, the PFAS national practice lead for Carollo Engineers, to get the details.
