Chemical and radiological sample results
MS0600002 , Big Field Water Association
30 of the 59 analytes this system has been tested for have been detected at least once, across 218 samples on record.
The other 29 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 218 samples on record, detections range from October 20, 2003 to July 20, 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 61–70 of 218 samples, newest first — collected December 11, 2019 to August 11, 2020. The summary above covers all 218.
23 results from the 10 samples listed here: 13 detected, 10 not detected. Across the whole record it is 206 of 1,564. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
