Chemical and radiological sample results
MS0690040 , Arkabutla Lake
4 of the 4 analytes this system has been tested for have been detected at least once, across 21 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 21 samples on record, detections range from November 29, 2004 to April 21, 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.
| Analyte | Kind | Detected in | First detected | Last detected |
|---|---|---|---|---|
| Nitrate-Nitrite 1038 | Inorganic Chemical | 11 of 20 results | Nov 29, 2004 | Apr 21, 2025 |
| Nitrate 1040 | Inorganic Chemical | 11 of 20 results | Nov 29, 2004 | Apr 21, 2025 |
| Sodium 1052 | Inorganic Chemical | 1 of 1 result | Nov 6, 2023 | Nov 6, 2023 |
| Nitrite 1041 | Inorganic Chemical | 1 of 20 results | Nov 29, 2004 | Nov 29, 2004 |
No date range is applied: this list draws on every sample on record. Show the last two years only.
The most recent samples, result by result
The table below lists 1–10 of 21 samples, newest first — collected May 13, 2015 to April 21, 2025. The summary above covers all 21.
28 results from the 10 samples listed here: 13 detected, 15 not detected. Across the whole record it is 24 of 61. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
