Chemical and radiological sample results

MS0140011 , Rena Lara Water Association

26 of the 57 analytes this system has been tested for have been detected at least once, across 247 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 247 samples on record, detections range from November 4, 1993 to September 17, 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 Rena Lara 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 241–247 of 247 samples, newest first — collected November 4, 1993 to November 4, 1993. The summary above covers all 247.

14 results from the 7 samples listed here: 14 detected, 0 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 Rena Lara Water Association, every result from 241 to 247 of 247 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
