The Molecular Detection for the Viability of Yersinia Cells During Shock Chlorination – A Pilot Scale Study

Efficient decontamination of pipeline system is an essential action in situations where a drinking water distribution system is contaminated. The challenge in decontamination is the fact that biofilms may protect faecal and pathogenic microbes against disinfectant after contamination event. The one of the most frequently used cleaning method for drinking water distribution networks is clorination. Shock‐chlorination can be used for purification of microbial contaminated water distribution system in waterborne outbreaks. As an example, shock‐chlorination was applied to clean the network after the severe waterborne outbreak in the Nokia city, Finland year 2007.
