Emerging contaminants are detected in urban stormwater and pose ecological and human health risks. The fate and transport of emerging contaminants in green stormwater infrastructure (GSI) is less studied. This session will improve understanding of emerging contaminant transport and potential removal is GSI and help identify effective design modifications. The 2025 National Monitoring Conference will focus on monitoring and research done in the Great Lakes, groundwater, streams, rivers, lakes, wetlands, estuaries, and oceans that address (but are not limited to) the following general themes and topics: Monitoring for the Protection of Aquatic Resources; Volunteer Monitoring and Community Collaborations; Increasing Inclusivity and Accessibility; Contaminants and Source Tracking; Open Data Life Cycle; and Measuring Success – Effectiveness Monitoring and Water Quality Trends.
