Chemical and radiological sample results

MS0560014 , Arlington W/A-Hintonville

16 of the 56 analytes this system has been tested for have been detected at least once, across 158 samples on record.

The other 40 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 158 samples on record, detections range from October 15, 2003 to April 9, 2025. 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 Arlington W/A-Hintonville, 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 158 samples, newest first — collected October 1, 2019 to October 12, 2021. The summary above covers all 158.

63 results from the 10 samples listed here: 14 detected, 49 not detected. Across the whole record it is 176 of 614. 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 Arlington W/A-Hintonville, every result from 61 to 70 of 158 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
