Data from a year-long monitoring campaign of a dam complex, located in the province of Córdoba, Argentinawere analyzed to characterize the best bacterial and viral groups that can reflect the microbiological water quality.The approach has been to monitor fecal coliforms, E. coli and enterococci together with the virus genomedetection for rotavirus group A, astrovirus, norovirus, JC polyomavirus and picobirnavirus and infectious humanenterovirus. Our results support that the presence of viral genomes as well as an infectious virus in areas wherefecal contamination was not demonstrated by bacterial indicators suggests prolonged virus persistence in aquaticenvironments and emphasizes the enteric virus groups as the most reliable for microbiological water qualityassessing. The combined detection of infectious human enterovirus and the genome of picobirnavirus could bepromising indicators of microbiological contamination derived from human and animal feces in the surface water.In addition, they could give information about the presence of the main viruses responsible for human acutegastroenteritis.
