Chemical and radiological sample results

MS0760079 , Jamie Whitten Delta States Research Cent

11 of the 42 analytes this system has been tested for have been detected at least once, across 145 samples on record.

The other 31 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 145 samples on record, detections range from April 25, 2017 to October 14, 2025. These figures cover the whole record.

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 Jamie Whitten Delta States Research 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 71–80 of 145 samples, newest first — collected April 4, 2022 to June 7, 2022. The summary above covers all 145.

17 results from the 10 samples listed here: 10 detected, 7 not detected. Across the whole record it is 151 of 445. 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 Jamie Whitten Delta States Research Cent, every result from 71 to 80 of 145 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
