About the Webinar
1. Microbial and Disinfection Byproducts (MDBP) Rules Revision Update
This presentation provides an overview of the regulatory process, summary of public engagements, topics under consideration, and the timeline with next steps regarding the potential regulatory revisions of eight National Primary Drinking Water Regulations (NPDWRs) included in five MDBP rules following the third Six-Year Review.
Presenter: Kenneth Rotert, EPA's Office of Water. Ken is a physical scientist with EPA's Office of Water, Office of Ground Water and Drinking Water, where he has worked on the development and review of drinking water regulations since 1998.
2. Challenges and Perspectives of Studying Water Storage Tank Ecosystems in Distribution Systems
Water storage tanks are vulnerable to contamination, and excess water retention time may cause depletion of disinfectant residual which creates an environment favorable for microbial contamination. This presentation evaluates the use of a field-based sampling and a pilot-scale experimental approach to understand the ecosystem of water storage tanks. An integrative approach was utilized to characterize the storage tank ecosystem and microbiome.
Presenter: Vicente Gomez-Alvarez, Ph.D., EPA's Office of Research and Development. Vicente is a microbiologist in EPA's Office of Research and Development, Center for Environmental Solutions and Emergency Response with 20 years of experience in planning and executing a diverse and intensive research project to study the microbiome in built and natural environments. His research focuses on microbial ecology, including the application of genomic technologies and the use of computational and bioinformatics workflow platforms for the characterization of microbial communities. He has led research projects on technological solutions for economic and environmental sustainability.
