Chemical and radiological sample results
MS0580001 , Algoma Water Association
25 of the 60 analytes this system has been tested for have been detected at least once, across 488 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 488 samples on record, detections range from October 15, 2003 to September 9, 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.

The most recent samples, result by result
The table below lists 391–400 of 488 samples, newest first — collected September 6, 2007 to May 18, 2009. The summary above covers all 488.
29 results from the 10 samples listed here: 10 detected, 19 not detected. Across the whole record it is 518 of 2,466. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
