Number of samples according to percentile categoriesa of measured and modeled PCE concentrations
| Measured PCE concentration | |||||
| ≤ 50th percentile | > 50–75th percentile | > 75th percentile | Total | ||
| Model estimated PCE concentration | ≤ 50th percentile | 28 | 10 | 6 | 44 |
| > 50–75th percentile | 12 | 7 | 3 | 22 | |

| Total | 45 | 21 | 22 | 88 | |
a 207 μg/L and 657 ug/L were the 50th and 75th percentile modeled PCE concentrations, respectively. 0.5 μg/L and 32 ug/L were the 50th and 75th percentile measured PCE concentrations, respectively.
