Chemical and radiological sample results

MS0170015 , City of Olive Branch

37 of the 66 analytes this system has been tested for have been detected at least once, across 1,108 samples on record.

The other 29 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 1,108 samples on record, detections range from December 1, 1992 to August 12, 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 City of Olive Branch, 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 491–500 of 1,108 samples, newest first — collected May 15, 2012 to July 16, 2012. The summary above covers all 1,108.

54 results from the 10 samples listed here: 7 detected, 47 not detected. Across the whole record it is 1,459 of 5,581. 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 City of Olive Branch, every result from 491 to 500 of 1,108 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
