Chemical and radiological sample results

MS0540019 , Corps of Engineers-Sardis Dam

3 of the 3 analytes this system has been tested for have been detected at least once, across 20 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 20 samples on record, detections range from August 24, 2005 to March 7, 2023. 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 Corps of Engineers-Sardis Dam, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.
Analyte Kind Detected in First detected Last detected
Nitrate-Nitrite 1038 Inorganic Chemical 4 of 20 results Jul 26, 2006 Mar 7, 2023
Nitrate 1040 Inorganic Chemical 4 of 20 results Jul 26, 2006 Mar 7, 2023
Nitrite 1041 Inorganic Chemical 1 of 20 results Aug 24, 2005 Aug 24, 2005

The most recent samples, result by result

The table below lists 1–10 of 20 samples, newest first — collected March 13, 2017 to February 11, 2026. The summary above covers all 20.

30 results from the 10 samples listed here: 6 detected, 24 not detected. Across the whole record it is 9 of 60. 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 Corps of Engineers-Sardis Dam, every result from 1 to 10 of 20 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
