Relative abundance of bacterial families residing in source and point-of-use water samples as determined by bTEFAP®.
Multi-colored stack bar graphs represent the relative abundance of bacterial family in each sample.

Dual Hierarchal dendrogram evaluation of the taxonomic classification of source and point-of-use water samples.
Samples are clustered on the X-axis and labeled based upon the water source types. Samples with more similar microbial populations are mathematically clustered closer together. The genera (consortium) are used for clustering. Thus the samples with more similar consortium of bacterial genera cluster closer together with the length of connecting lines (top of heatmap) related to the similarity, shorter lines between two samples indicate closely matched bacterial consortium. The heatmap represents the relative percentages of each bacterial genus. The predominant genera are represented along the right Y-axis. The legend for the heatmap is provided in the upper left corner.

Rarefaction curves showing observed taxonomic units of bacterial species diversity in the source and point-of-use water samples.

PCoA analysis of the microbiome of each water sample based upon UniFrac method.
Different colored symbols are indicative of the different major source and point-of-use water samples. Symbols that are closer together represent similar bacterial community compositions.
