Chemical and radiological sample results
MS0150011 , Town of Wesson
23 of the 64 analytes this system has been tested for have been detected at least once, across 296 samples on record.
The other 41 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 296 samples on record, detections range from December 16, 1993 to September 25, 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 131–140 of 296 samples, newest first — collected July 17, 2008 to July 17, 2008. The summary above covers all 296.
20 results from the 10 samples listed here: 10 detected, 10 not detected. Across the whole record it is 345 of 894. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
