Chemical and radiological sample results
MS0010019 , Natchez State Park-B
4 of the 4 analytes this system has been tested for have been detected at least once, across 28 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 28 samples on record, detections range from November 29, 2004 to February 2, 2026. 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 | 25 of 27 results | Nov 29, 2004 | Feb 2, 2026 |
| Nitrate 1040 | Inorganic Chemical | 25 of 27 results | Nov 29, 2004 | Feb 2, 2026 |
| Sodium 1052 | Inorganic Chemical | 1 of 1 result | Jan 19, 2021 | Jan 19, 2021 |
| Nitrite 1041 | Inorganic Chemical | 1 of 27 results | Oct 19, 2011 | Oct 19, 2011 |

The most recent samples, result by result
The table below lists 21–28 of 28 samples, newest first — collected November 29, 2004 to January 18, 2011. The summary above covers all 28.
24 results from the 8 samples listed here: 12 detected, 12 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
