Chemical and radiological sample results
MS0150020 , Copiah W/A - Bayou Pierre #2
11 of the 13 analytes this system has been tested for have been detected at least once, across 135 samples on record.
The other 2 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 135 samples on record, detections range from May 4, 1994 to September 30, 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 41–50 of 135 samples, newest first — collected December 6, 2019 to December 11, 2019. The summary above covers all 135.
20 results from the 10 samples listed here: 16 detected, 4 not detected. Across the whole record it is 167 of 315. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
