Occurrence of F-Specific Bacteriophages in Untreated and Treated Wastewaters in Mumbai.

Unlabelled: F + coliphages are considered as potential enteric viral indicators in water systems as a tool for on-site validation of wastewater treatment processes. The present study evaluated the occurrence of F + coliphages in wastewaters collected from three wastewater treatment plants (WWTPs) in Mumbai city, to assess this potential. The detection and enumeration of F + coliphages was carried out from WWTPs Z1, Z3 and Z5 using the ISO 10705-1 and U.

Wastewater-Based Epidemiology of SARS-CoV-2: Assessing Prevalence and Correlation with Clinical Cases.

Wastewater-based epidemiology has been recognized as a tool to monitor the progress of COVID-19 pandemic worldwide. The study presented herein aimed at quantitating the SARS-CoV-2 RNA in the wastewaters, predicting the number of infected individuals in the catchment areas, and correlating it with the clinically reported COVID-19 cases. Wastewater samples (n = 162) from different treatment stages were collected from three wastewater treatment plants (WWTPs) from Mumbai city during the 2nd surge of COVID-19 (April 2021 to June 2021).
