Agenda and Recordings for the 17th Annual EPA Drinking Water Workshop (Virtual)

Session Recordings

The 17th Annual EPA Drinking Water Workshop, held in partnership with the Association of State Drinking Water Administrators (ASDWA), took place virtually on August 31-September 3, 2020. The workshop provided in-depth information and training on solutions and strategies for handling small drinking water system challenges with a focus on monitoring, distribution, source, and treatment topics. 

Links to the technical and training session recordings are provided below. Certificates cannot be provided for viewing recordings.

In-Depth Training Sessions

T1. Sanitary Surveys-Filtration and Disinfection
This training was intended for water professionals, state drinking water program staff, and technical assistance providers that conduct sanitary surveys. This half-day training focused on evaluating filtration and disinfection technologies, including alternative treatment technologies as part of a sanitary survey. Presentations included examples from surveys and exercises. There were opportunities for open discussion among participants and Q&A with the presenters.

Trainers: Michael Finn, EPA-OW and Andrea Traviglia, EPA-Region 1

T2. Corrosion Control Treatment Training
This training provided an overview of internal corrosion control theory and technologies for drinking water systems, primacy agencies, and consultants to assist them in implementing corrosion control treatment (CCT). An overview of corrosion, including how and under what conditions it occurs; performing CCT assessment; and selecting and implementing the appropriate CCT was discussed.

Trainers: Phil Brandhuber, BWQ; Dave Cornwell, Cornwell Engineering; Nancy McTigue, Cornwell Engineering; Melinda Friedman, Confluence Engineering; Rebecca Slabaugh, Arcadis; Stacy Jones, Indiana Department of Environmental Management; and Melanie Criswell, Colorado Department of Public Health and Environment

T3. Distribution System and Treatment Models
This training included the following models:

  • ETDOT: Information generated from this suite of models will provide states and utilities a better understanding of the fundamentals of carbon adsorption for the removal of contaminants, including PFAS, and what that means to the operation, performance, and costs associated with this technology.
  • EPANET: This open source software application is used throughout the world to model water distribution systems and can be used for many different types of applications in distribution systems analysis. Continued development and bug fixes are occurring under an open source project site.

Trainers: Thomas Speth, Johnathan Burkhardt, Robert Janke, and Feng Shang, EPA-ORD
