Chemical and radiological sample results
MS0030005 , Mary Springs Water Association
21 of the 55 analytes this system has been tested for have been detected at least once, across 359 samples on record.
The other 34 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 359 samples on record, detections range from August 16, 1993 to July 21, 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 291–300 of 359 samples, newest first — collected June 3, 1996 to June 22, 1999. The summary above covers all 359.
20 results from the 10 samples listed here: 6 detected, 14 not detected. Across the whole record it is 389 of 1,514. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
