Chemical and radiological sample results
MS0140002 , Clarksdale Public Utilities
30 of the 59 analytes this system has been tested for have been detected at least once, across 1,252 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 1,252 samples on record, detections range from July 6, 1992 to July 9, 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 751–760 of 1,252 samples, newest first — collected March 24, 2008 to March 26, 2008. The summary above covers all 1,252.
20 results from the 10 samples listed here: 4 detected, 16 not detected. Across the whole record it is 2,029 of 5,159. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
