Cesare 11, 70124 Bari, Italy This study evaluated whether some chemical and microbial contaminants in treated sewage effluents from two wastewater treatment plants WWTP reached the groundwater when they drained through a fractured karst vadose zone WWTP K and a porous vadose zone WWTP P . Forty five samples of sewage water SW , treated water TW , and monitoring well MW , collected from WWTPP 24 and WWTP K 21 , were analyzed for a range of microbiological and chemical properties. The E. coli and Salmonella counts were below the limits outlined in the Legislative Decree 152/06 in effluents from both types of WWTP. Enteric viruses were found in 37.5% and 12.5% of the SW and TW from WWTP P, respectively. The percentages of Pepper mild mottle virus isolated were higher in TW 62.5% in WWTP P, 85.7% in WWTP K than in SW and MW. The residual concentrations of contaminants of emerging concern CEC of each drug category were higher in the MW downstream of WWTP K than of WWTP P. Our results showed that the porous vadose zone was more effective at reducing the contaminant loads than the fractured karst one, especially the CEC, in the effluent. The legislation should include other parameters to minimize the risks from treated effluent that is discharged to soil. 11 Published version https //www.mdpi.com/2076 0817/11/6/677 08/06/2022 Articolo in rivista Molecular Diversity Preservation International 2076 0817 Pathogens Pathogens BRIGIDA SILVIA DE CEGLIE CRISTINA mariaclementina.caputo CAPUTO MARIA CLEMENTINA sapia.murgolo MURGOLO SAPIA giuseppe.mascolo MASCOLO GIUSEPPE |
