WHO practical guide to quantitative microbial risk assessment, QMRA

During the Singapore International Water Week the World Health Organisation (WHO) launched a practical guide for carrying out quantitative microbial risk analyses (QMRA). Risk analyses are the backbone of the WHO guidelines in the field of water (drinking water, swimming water, reuse of waste water). Regulatory bodies such as water companies had a need for a practical guide to carrying out microbial risk analyses, which help them to implement the WHO guidelines. At the same time KWR, as the WHO Collaborating Centre for Water Quality and Health, has made an important contribution to the creation of the practical guide.

Gertjan Medema explains the QMRA guide: application for Water Safety Management during the launch

Gertjan Medema (KWR), Susan Petterson (Water & Health, Australia) and Nick Ashbolt (US EPA and University of Alberta, Canada) have drawn up the guide, which was subsequently reviewed by a broad group of international experts. QMRA: application for Water Safety Management was presented during a special session of the Singapore International Water Week. The guide is freely available and can be downloaded for free from the WHO website.
