Greater recovery of spiked viruses, influenza A/B viruses (flu-A/B), measles virus (MeV), murine norovirus (MNV), SARS-CoV-2 (N1), norovirus GII (NoVGII), bacteriophage phi6 (Phi6), and rotavirus (RoV) in deionized water (DW) compared to wastewater (WW). Data derived from all concentration methods. (a) All spiked virus recovery results combined. (b) Recovery by individual virus. Boxes depict the 25th, 50th, and 75th percentile ranges after omitting outliers greater or less than ±1.5× the interquartile range (IQR), which is shown by the whiskers.
