Earth Day 2026 finds the ASCE Plot Points podcast celebrating with a conversation between Xavi Fonoll Almansa, an assistant professor of environmental Engineering at the University of Texas, at Austin, and guest host Khuang Zhu of the ASCE Environmental and Water Resources Institute’s Environmental Health and Water Quality Committee. In episode 190 of ASCE Plot Points, they discuss resource recovery, future technologies and processes, and Fonoll Almansa’s cutting edge research right now into hydrothermal liquefaction, converting organic waste into biocrude.

Kristin Schultheis is a senior project planner at the Milwaukee Metropolitan Sewerage District. And that likely conjures images of urban areas, working across the biggest city in Wisconsin. And that would be accurate. But Schultheis' work encompasses a much larger area than the city proper with challenges and opportunities that extend into the surrounding rural areas and even active farmland. In episode 189 of ASCE Plot Points, Schultheis talks with guest hosts Brianne Duncan and Wendy Cohen of the ASCE Environmental and Water Resources Institute’s Environmental Health and Water Quality Committee.

This week, in recognition of Earth Day, the ASCE Environmental and Water Resources Institute's Environmental Health and Water Quality Committee is bringing three conversations to the ASCE Plot Points podcast. The first, in episode 188 of ASCE Plot Points, is with William Gonwa, Ph.D., program director for civil Engineering, civil and architectural engineering, and construction management at the Milwaukee School of Engineering. With special co-hosts Brianne Duncan and Lauren Redfern, Gonwa discusses his more than four decades in the profession and how building your own statistical models can help solve your project's problems.
