Chemical and radiological sample results
MS0410026 , Tombigbee State Park
4 of the 4 analytes this system has been tested for have been detected at least once, across 23 samples on record.
The other 0 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 23 samples on record, detections range from November 29, 2004 to February 16, 2022. 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.
| Analyte | Kind | Detected in | First detected | Last detected |
|---|---|---|---|---|
| Nitrate-Nitrite 1038 | Inorganic Chemical | 6 of 22 results | Nov 29, 2004 | Nov 12, 2019 |
| Nitrite 1041 | Inorganic Chemical | 5 of 22 results | Nov 29, 2004 | Nov 12, 2019 |
| Nitrate 1040 | Inorganic Chemical | 3 of 22 results | Aug 15, 2005 | Nov 12, 2019 |
| Sodium 1052 | Inorganic Chemical | 1 of 1 result | Feb 16, 2022 | Feb 16, 2022 |

The most recent samples, result by result
The table below lists 1–10 of 23 samples, newest first — collected March 6, 2017 to February 23, 2026. The summary above covers all 23.
28 results from the 10 samples listed here: 4 detected, 24 not detected. Across the whole record it is 15 of 67. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
