In Group 1, Lovö vattenverk, Görvälnverket and Kvarnagårdens vattenverk showed reductions where p values were nearly significant ( p < 0.05) (Table 2 ). 3.4 Temporal Differences in Contigs Homologous to Viral Sequences at the Different DWTPs Contigs homologous to viruses of all categories tended to be more prevalent in the raw waters collected in March–July, followed by a decrease in November–December (Figures 6 and 7 ) in the three DWTPs with the highest number of contigs in the raw water samples (Lovö vattenverk, Görvälnverket and Vombverket).
