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.
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.

The most recent samples, result by result
The table below lists 131–140 of 301 samples, newest first — collected December 5, 2011 to April 18, 2012. The summary above covers all 301.
33 results from the 10 samples listed here: 2 detected, 31 not detected. Across the whole record it is 345 of 1,407. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
