Abstract
A total of 48 water samples were collected from six water treatment plants in Wuhan and analyzed by realtime PCR assay for viral identification of enterovirus EV rotavirus group A RVA human adenovirus HAdV as well as human adenovirus subgroup F HAdVF during the period from December 2010 to October 2011 HAdV HAdVF and RVA were all positively detected in the samples of source water and treated drinking water EV could be found in 46 11/24 of all the source water samples but only 21 5/24 positive in treated drinking water The concentrations of these three kinds of enteric viruses detected were as follows HAdV RVA EV The highest removal rate was EV 97 followed by RVA 82 HAdV 73 and HAdVF 72 HAdV and RVA have been abundant in untreated river water and finished water after conventional processes of water treatment plants while bacterial indicators could not be detected in tap water which met the standard of China for drinking water bacterial quality Some factors that could affect the accuracy of qPCR detection are also discussed in this study
