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 21–30 of 302 samples, newest first — collected July 11, 2022 to February 26, 2024. The summary above covers all 302.

44 results from the 10 samples listed here: 33 detected, 11 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.

We withheld the location of 4 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.

Chemical and radiological sample results for Town of Coahoma, every result from 21 to 30 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.
