Factors Influencing Bacterial Diversity and Community Composition in Municipal Drinking Waters in the Ohio River Basin, USA
Fig 4
Dot plot showing the relative abundances of common (≥ 1%) bacterial OTUs that differed significantly by disinfection type (nested ANOVA, threshold P<0.01).
Municipality was used as a nested variable. Colored bar along the x-axis indicates disinfectant type (blue = chlorine, orange = chloramine). Taxonomic identities are listed as phylum/genus or subphylum/genus for proteobacterial OTUs. Note the similarities between chloraminated samples and M11S3, which had exceptionally high iron.
