The most recent samples, result by result

The table below lists 1–10 of 22 samples, newest first — collected May 4, 2016 to March 24, 2025. The summary above covers all 22.

30 results from the 10 samples listed here: 0 detected, 30 not detected. Across the whole record it is 0 of 66. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for Chickasaw Hills, every result from 1 to 10 of 22 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
