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.

Every analyte ever detected for Natchez State Park-B, 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 25 of 27 results Nov 29, 2004 Feb 2, 2026
Nitrate 1040 Inorganic Chemical 25 of 27 results Nov 29, 2004 Feb 2, 2026

The most recent samples, result by result

The table below lists 11–20 of 28 samples, newest first — collected October 19, 2011 to January 17, 2017. The summary above covers all 28.

30 results from the 10 samples listed here: 21 detected, 9 not detected. Across the whole record it is 52 of 82. 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 Natchez State Park-B, every result from 11 to 20 of 28 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
