This session on water purification methods with Georg Pleninger will explore practical, field-ready strategies for ensuring safe drinking water in austere and resource-limited environments. Drawing from his experience as a paramedic, WASH program coordinator, and global health practitioner working across Sub-Saharan Africa and conflict settings, Georg brings a real-world perspective to water safety challenges in diverse environments. Participants will learn to evaluate water sources, select appropriate purification techniques—including filtration, chemical treatment, and improvised methods—and understand the limitations of each approach. The lecture will also highlight common pathogens, risk mitigation strategies, and how to adapt water purification practices in both wilderness and humanitarian contexts. Ideal for outdoor enthusiasts, expedition medics, and global health providers, this talk equips learners with essential knowledge to prevent waterborne illness and maintain operational readiness in the field.
