Chemical and radiological sample results

MS0600004 , Darling Water Association

27 of the 59 analytes this system has been tested for have been detected at least once, across 195 samples on record.

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 195 samples on record, detections range from October 27, 2003 to September 30, 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 Darling Water Association, 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 191–195 of 195 samples, newest first — collected October 27, 2003 to March 22, 2004. The summary above covers all 195.

45 results from the 5 samples listed here: 7 detected, 38 not detected. 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 Darling Water Association, every result from 191 to 195 of 195 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
