This educational video illustrates how per- and polyfluoroalkyl substances (PFAS) enter and move through surface water systems due to wastewater discharges from a petroleum refinery. Using a visually intuitive approach, the video helps viewers understand how different PFAS compounds, including telomers associated with AFFF (aqueous film-forming foam), appear in environmental samples.

This video counters the common narrative that farmers are universally exploitative of groundwater resources. It highlights the issue of aquifer depletion, but also describes a growing awareness and proactive efforts among farmers to reduce water usage, adopt more efficient irrigation technologies, and even shift to less water-intensive crops.

This sand tank demonstration provides an excellent visualization of how dense non-aqueous phase liquid (DNAPL) migrates in an aquifer, highlighting key factors influencing groundwater contamination.

The video explores the natural beauty and hydrogeological complexity of karst landscapes in Slovenia and Croatia, but the educational film and animations are applicable to learning about Karst in general. The issue of transboundary aquifer management in these formation is also presented.

Dr. John Cherry makes the case that access to groundwater is key to the long-term sustainability of human well-being.

This animation illustrates fate and transport phenomena of non-aqueous phase liquid (DNAPL) in fractured rock.
