Taxonomic composition of reclaimed water (RW) and zero-valent iron sand filtered reclaimed water (ZW). a Percent of the normalized abundances (relative abundance) of the taxonomic assignments for RW and ZW viromes. b Heatmap showing the normalized abundances (logx + 1 transformed) of the viral taxa in the RW and ZW viromes. The heatmap has samples as columns (colored by water type) and viral taxa as rows (colored by putative host). Normalized abundance measured as contig coverage divided by the sum contig coverage per million
