Chemical and radiological sample results

MS0510010 , South Newton Rural W/A #1

37 of the 72 analytes this system has been tested for have been detected at least once, across 274 samples on record.

The other 35 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 274 samples on record, detections range from October 15, 2003 to December 2, 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 South Newton Rural W/A #1, 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 71–80 of 274 samples, newest first — collected July 21, 2020 to December 10, 2020. The summary above covers all 274.

59 results from the 10 samples listed here: 52 detected, 7 not detected. Across the whole record it is 370 of 1,459. 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 South Newton Rural W/A #1, every result from 71 to 80 of 274 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
