Chemical and radiological sample results

MS0250023 , South Terry Water Assn

26 of the 57 analytes this system has been tested for have been detected at least once, across 409 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 409 samples on record, detections range from August 30, 1993 to February 13, 2025. These figures cover the whole record; the list of samples further down is narrowed.

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 Terry Water Assn, 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 1–10 of 16 samples, newest first — collected February 13, 2025 to February 25, 2026. The summary above covers all 16.

78 results from the 10 samples listed here: 12 detected, 66 not detected. Across the whole record it is 615 of 2,342. 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 Terry Water Assn, every result from 1 to 10 of 16 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
