This session will introduce vermifiltration as an accessible, nature-based water treatment approach with practical applications relevant to conservation districts, resource planners, and field professionals. The presentation will provide an overview of vermifiltration fundamentals, including system components, earthworm-microbe interactions, and how design and operating conditions influence treatment performance._x000D_ Real-world examples will be used to illustrate how vermifiltration has been implemented to improve water quality in agricultural, small community, and decentralized treatment contexts. Participants will gain a clearer understanding of where vermifiltration is most effective, key considerations for implementation and monitoring, and lessons learned from applied projects. The session will conclude with discussion of how vermifiltration can be integrated into broader watershed planning and conservation strategies as a complementary tool for improving local water quality.
