Chemical and radiological sample results

MS0760001 , Town of Arcola

26 of the 57 analytes this system has been tested for have been detected at least once, across 348 samples on record.

The other 31 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 348 samples on record, detections range from November 3, 2003 to February 24, 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 Town of Arcola, 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 61–70 of 348 samples, newest first — collected September 1, 2020 to September 1, 2020. The summary above covers all 348.

20 results from the 10 samples listed here: 14 detected, 6 not detected. Across the whole record it is 504 of 2,218. 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 Town of Arcola, every result from 61 to 70 of 348 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
