Chemical and radiological sample results
MS0060053 , Deeson Roundlake #2
24 of the 58 analytes this system has been tested for have been detected at least once, across 204 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 204 samples on record, detections range from December 11, 2000 to April 29, 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 91–100 of 204 samples, newest first — collected October 11, 2007 to April 7, 2008. The summary above covers all 204.
47 results from the 10 samples listed here: 19 detected, 28 not detected. Across the whole record it is 332 of 700. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
