Chemical and radiological sample results
MS0150018 , Copiah County Industrial Park
15 of the 54 analytes this system has been tested for have been detected at least once, across 280 samples on record.
The other 39 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 280 samples on record, detections range from September 22, 1993 to March 10, 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 61–70 of 280 samples, newest first — collected August 19, 2015 to September 26, 2018. The summary above covers all 280.
19 results from the 10 samples listed here: 9 detected, 10 not detected. Across the whole record it is 310 of 837. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
