All viral (HAdV, JCPyV, MCPyV and NoV GGII) and bacterial (EC
and IE) parameters were quantified bimonthly in all river water
samples (sites A and B) and in all seawater samples from the beach
affected by the Llobregat river plume (site D). Raw wastewater and
two differently treated effluents from a WWTP (site C) were
simultaneously collected and also tested for the presence of HEV by
nPCR.
