Chemical and radiological sample results

MS0790033 , Wilkinson Co Correctional Cent

36 of the 71 analytes this system has been tested for have been detected at least once, across 181 samples on record.

The other 35 were tested for and never found. An analyte is counted here if any result on record measured it, so this covers the whole history and not the samples listed below.

Across all 181 samples on record, detections range from November 3, 2003 to February 19, 2026. These figures cover the whole record; the list of samples further down is narrowed.

What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.

What has been detected, ever

Every analyte measured above its reporting level at any point in this system’s record, most often detected first. This is not limited to the samples listed below.

Every analyte ever detected for Wilkinson Co Correctional Cent, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 11–16 of 16 samples, newest first — collected November 25, 2024 to June 9, 2025. The summary above covers all 16.

67 results from the 6 samples listed here: 19 detected, 48 not detected. 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 Wilkinson Co Correctional Cent, every result from 11 to 16 of 16 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
