Chemical and radiological sample results
MS0230075 , Silver Slipper Casino & Hotel
13 of the 49 analytes this system has been tested for have been detected at least once, across 144 samples on record.
The other 36 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 March 20, 2020 to July 7, 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 141–144 of 144 samples, newest first — collected March 20, 2020 to March 26, 2020. The summary above covers all 144.
8 results from the 4 samples listed here: 4 detected, 4 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
