Chemical and radiological sample results
MS0610012 , Langford Water Association
38 of the 73 analytes this system has been tested for have been detected at least once, across 436 samples on record.
The other 35 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 436 samples on record, detections range from October 20, 2003 to August 10, 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 51–60 of 436 samples, newest first — collected August 8, 2023 to April 8, 2024. The summary above covers all 436.
26 results from the 10 samples listed here: 8 detected, 18 not detected. Across the whole record it is 522 of 2,491. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
