Functional composition of reclaimed water (RW) and zero-valent iron sand filtered reclaimed water (ZW). a Percent of the normalized abundances (relative abundance) of the SEED subsystems assignments for RW and ZW viromes. b Normalized abundance of antibiotic resistance genes in RW and ZW viromes. Shapes denote month samples were collected (June, square; July, triangle; August, circle) and color denotes water type (RW, light blue; ZW, dark blue). Normalized abundance measured as ORF coverage divided by sum ORF coverage per million
