Chemical and radiological sample results

MS0700008 , City of Ripley

28 of the 61 analytes this system has been tested for have been detected at least once, across 795 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 795 samples on record, detections range from July 30, 2002 to July 21, 2026. 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 City of Ripley, 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 11–20 of 46 samples, newest first — collected September 22, 2025 to November 19, 2025. The summary above covers all 46.

10 results from the 10 samples listed here: 0 detected, 10 not detected. Across the whole record it is 735 of 4,078. 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 City of Ripley, every result from 11 to 20 of 46 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
