No date range is applied: this list draws on every sample on record. Show the last two years only.

The most recent samples, result by result

The table below lists 1–10 of 15 samples, newest first — collected May 13, 2009 to March 24, 2025. The summary above covers all 15.

30 results from the 10 samples listed here: 0 detected, 30 not detected. Across the whole record it is 0 of 45. 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 U S Army Corps-Wallace Creek, every result from 1 to 10 of 15 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
