Laboratory workflows represented by the participants of the first 2 rounds of the Wisconsin Wastewater Monitoring Program wastewater proficiency testing program in study of implementation and early outcomes of laboratory proficiency testing program for National Wastewater Surveillance System, United States, 2024. Each symbol represents a single laboratory’s wastewater processing workflow (some laboratories tested multiple workflows). Laboratories are separated by the wastewater fraction processed (y-axis). Bold outline indicates new participants in round 2. Asterisks indicate laboratories that implemented a method change from round 1 to round 2.
