Chemical and radiological sample results

MS0220059 , U S Engineers - Piney Woods

3 of the 4 analytes this system has been tested for have been detected at least once, across 21 samples on record.

The other 1 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 June 14, 2006 to February 10, 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 U S Engineers - Piney Woods, 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 17 of 20 results Jun 14, 2006 Feb 10, 2026
Nitrate 1040 Inorganic Chemical 17 of 20 results Jun 14, 2006 Feb 10, 2026
Sodium 1052 Inorganic Chemical 1 of 1 result Feb 10, 2021 Feb 10, 2021

The most recent samples, result by result

The table below lists 1–10 of 21 samples, newest first — collected November 17, 2020 to February 10, 2026. The summary above covers all 21.

28 results from the 10 samples listed here: 15 detected, 13 not detected. Across the whole record it is 35 of 61. 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 U S Engineers - Piney Woods, every result from 1 to 10 of 21 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
