Chemical and radiological sample results
MS0480008 , Town of Hatley
18 of the 58 analytes this system has been tested for have been detected at least once, across 174 samples on record.
The other 40 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 174 samples on record, detections range from October 8, 2003 to July 13, 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 41–50 of 174 samples, newest first — collected July 21, 2020 to March 31, 2021. The summary above covers all 174.
27 results from the 10 samples listed here: 8 detected, 19 not detected. Across the whole record it is 158 of 1,012. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
