Join WateReuse Ohio to get a detailed overview of the risk-based approach for designing and monitoring water reuse systems. Drs. Michael Jahne and Jay Garland from the U.S. EPA’s Office of Research and Development will describe how quantitative microbial risk assessment (QMRA) has been used to define pathogen log reduction targets (LRTs) for reuse systems and present emerging work on chemical risk methods to inform treatment. Translating the risk models into crediting frameworks to inform the design of treatment systems will be discussed, as well as shifting from end point water quality measurements to surrogate monitoring to assess performance. The development of the risk-based approach will be illustrated using a range of alternative source waters and end uses, with concluding remarks on the key next steps for continued advancement.
Moderator:
- Jessica Langdon, Assistant Policy Director, Ohio EPA
Presenters:
