Occurrence of pathogens in the river-groundwater interface in a losing river stretch (Besòs River Delta, Spain).

The aim of this study is to investigate the occurrence of faecal indicator and microbial pathogens (bacteria and virus) in the shallow urban aquifer of the Besòs River Delta (NE Spain). To this end, human adenovirus (HAdV) andNorovirus of genogroups I and II (NoV GI and NoV GII) aswell as the faecal...

To this end, human adenovirus (HAdV) andNorovirus of genogroups I and II (NoV GI and NoV GII) aswell as the faecal indicator bacteria (FIB) Escherichia coli (EC) and faecal enterococci (FE) were monitored in groundwater and in the River Besòs in December 2013 and in July 2104.
