Chemical and radiological sample results

MS0270004 , Town of Louise

20 of the 57 analytes this system has been tested for have been detected at least once, across 301 samples on record.

The other 37 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 301 samples on record, detections range from September 9, 1993 to March 26, 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 Town of Louise, 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 11–13 of 13 samples, newest first — collected October 21, 2024 to November 18, 2024. The summary above covers all 13.

23 results from the 3 samples listed here: 9 detected, 14 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

We withheld the location of 2 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.

Chemical and radiological sample results for Town of Louise, every result from 11 to 13 of 13 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
