Chemical and radiological sample results
MS0110003 , Hermanville Water Association
36 of the 59 analytes this system has been tested for have been detected at least once, across 713 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 713 samples on record, detections range from October 19, 1993 to September 16, 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 681–690 of 713 samples, newest first — collected March 29, 1994 to March 29, 1994. The summary above covers all 713.
20 results from the 10 samples listed here: 9 detected, 11 not detected. Across the whole record it is 875 of 5,022. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
