Chemical and radiological sample results
MS0130019 , Golden Triangle W/A #2
13 of the 13 analytes this system has been tested for have been detected at least once, across 144 samples on record.
The other 0 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 144 samples on record, detections range from August 9, 1993 to September 26, 2025. 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 121–130 of 144 samples, newest first — collected February 15, 1994 to June 13, 1995. The summary above covers all 144.
20 results from the 10 samples listed here: 7 detected, 13 not detected. Across the whole record it is 155 of 384. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
