SESSION 10: In-Depth Training (Not recorded sessions)
SESSION 10A: Corrosion This session covered the fundamentals of lead and copper release including corrosion, the role of particles, and metal solubility relationships in drinking water. Distribution system assessment approaches, including water sampling strategies and pipe scale analyses, were also addressed. Lastly, corrosion control strategies and corrosion control assessment tools were presented. Cases study data were used to illustrate important messages where appropriate. Trainer: Darren Lytle, Simoni Triantafyllidou, Michael Schock, Mike DeSantis, Jennifer Tully, and Stephen Harmon, EPA-ORD SESSION 10B: Drinking Water Microbiology This session provided an introduction to drinking water microbiology and EPA’s regulatory requirements for microbial monitoring. Many of the common drinking water microbial methods required by regulations were also be demonstrated. Attendees had the opportunity to perform microbiological tests alongside EPA scientists and to examine previously run tests. Trainers: Laura Boczek, EPA-ORD and Jennifer Best, EPA-OW SESSION 10C: Sanitary Surveys This session provided information for state and federal public water system oversight personnel on evaluating water treatment processes as part of sanitary surveys or technical assistance for public water systems. Presenters were experienced field staff from multiple agencies. Trainers: Michael Finn and Derek Losh, EPA-OW
