Chemical and radiological sample results

MS0140003 , Town of Coahoma

28 of the 58 analytes this system has been tested for have been detected at least once, across 302 samples on record.

The other 30 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 302 samples on record, detections range from December 8, 1993 to February 10, 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.

Every analyte ever detected for Town of Coahoma, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 261–270 of 302 samples, newest first — collected September 19, 2000 to April 13, 2004. The summary above covers all 302.

86 results from the 10 samples listed here: 20 detected, 66 not detected. Across the whole record it is 617 of 1,389. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for Town of Coahoma, every result from 261 to 270 of 302 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
