Chemical and radiological sample results

MS0780009 , Sapa Water System

18 of the 50 analytes this system has been tested for have been detected at least once, across 165 samples on record.

The other 32 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 165 samples on record, detections range from November 15, 2004 to February 17, 2026. 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 Sapa Water System, 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 61–70 of 165 samples, newest first — collected October 25, 2022 to April 10, 2023. The summary above covers all 165.

56 results from the 10 samples listed here: 5 detected, 51 not detected. Across the whole record it is 325 of 828. 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 Sapa Water System, every result from 61 to 70 of 165 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
