Extended Data Fig. 7: RPKMs of level 2 functions in the nitrogen cycle of St. Louis premise plumbing water in comparison to a pilot-scale hot water plumbing rig study.

A heatmap showing RPKMs of level 2 functions in the nitrogen cycle of St. Louis premise plumbing water from this study (STL-1 through 8) in comparison to a previously published pilot-scale hot water plumbing rig study in Blacksburg, VA (those samples of which the sample names starting with “T”, Dai et al., 2018).
