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.

The most recent samples, result by result
The table below lists 81–90 of 145 samples, newest first — collected October 28, 2021 to March 9, 2022. The summary above covers all 145.
50 results from the 10 samples listed here: 8 detected, 42 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.
