Chemical and radiological sample results

MS0670006 , City of Indianola

39 of the 74 analytes this system has been tested for have been detected at least once, across 621 samples on record.

The other 35 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 621 samples on record, detections range from July 30, 2002 to December 5, 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.

Every analyte ever detected for City of Indianola, 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 411–420 of 621 samples, newest first — collected March 26, 2012 to May 22, 2013. The summary above covers all 621.

51 results from the 10 samples listed here: 12 detected, 39 not detected. Across the whole record it is 709 of 2,915. 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 Indianola, every result from 411 to 420 of 621 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
