Chemical and radiological sample results

MS0030007 , Wilk-Amite W/A #1-South

25 of the 58 analytes this system has been tested for have been detected at least once, across 782 samples on record.

The other 33 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 782 samples on record, detections range from August 3, 1993 to July 28, 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 Wilk-Amite W/A #1-South, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 411–420 of 782 samples, newest first — collected October 26, 2016 to March 22, 2017. The summary above covers all 782.

40 results from the 10 samples listed here: 18 detected, 22 not detected. Across the whole record it is 1,202 of 2,346. 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 Wilk-Amite W/A #1-South, every result from 411 to 420 of 782 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
