Upcoming IWA Webinar –Traditional and molecular indicators to characterise sewage in wastewater-based epidemiology

3 DECEMBER 2021 | 14:00 (London Time)

We are pleased to announce the upcoming IWA webinar organised by the Specialist Group on Health Related Water Microbiology (HRWM)’

The webinar will take place on Friday 3 December 2021 at 15:00 Amsterdam (CEST), 14:00 London (BST), 09:00 New York (EDT), 21:00 Beijing (CST). Register Now !

Description

The webinar will give an overview on available microbial source tracking (MST) technologies and faecal indicators to support wastewater-based epidemiology (WBE). The webinar will focus on data interpretation, improving data comparability and quality control from sewage surveillance activities. Presentation/discussion of MST markers and indicators (bacterial, viral, others) which enable:

  • the specific tracking of human sewage pollution,
  • the characterisation of unknown sewage effluents,
  • the normalisation of SARS-CoV-2 qPCR data, and
  • the determination of microbial/viral treatment efficacies of WWTP.

Molecular (e.g. PCR based) and cultivation-based diagnostic methods will also be discussed.
