Chemical and radiological sample results

MS0610086 , Thomasville W/A #2

24 of the 57 analytes this system has been tested for have been detected at least once, across 205 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 205 samples on record, detections range from October 20, 2003 to July 30, 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 Thomasville W/A #2, 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 51–60 of 205 samples, newest first — collected June 18, 2019 to May 24, 2023. The summary above covers all 205.

58 results from the 10 samples listed here: 0 detected, 58 not detected. Across the whole record it is 289 of 1,357. 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 Thomasville W/A #2, every result from 51 to 60 of 205 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
