Table 1.
Average Faith’s (Faith and Baker, 2006) phylogenetic diversity (PD) calculated for groundwater and grouped mineral deployment 16S rRNA gene amplicon libraries.
| Sample/group | Average phylogenetic diversity (PD) |
|---|---|

| Post-deployment GW 3–27 | 76.2 |
| Pre-deployment GW 3–24 | 72.4 |
| Above RTZ 3–27 | 60.3 ± 3.40 |
| Above RTZ 3–24 | 54.7 ± 4.10 |
| Within RTZ 3–27 | 40.5 ± 2.94 |
| Within RTZ 3–24 | 37.2 ± 4.30 |
| Below RTZ 3–24 | 32.6 |
| Below RTZ 3–27 | 29.6 ± 1.84 |
| Pre-deployment GW 3–27 | 23.4 |
The values presented in the table correspond PD values calculated for the maximum number (n = 2000) of sequences included in the rarefaction analysis shown in Figure 2. Table is sorted in order of decreasing PD value. Error terms account for the variation among samples within a group; no error was calculated for groups containing only one sample.
