Chemical and radiological sample results

MS0820014 , City of Yazoo City

28 of the 60 analytes this system has been tested for have been detected at least once, across 629 samples on record.

The other 32 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 629 samples on record, detections range from July 30, 2002 to July 20, 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 Yazoo City, 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 371–380 of 629 samples, newest first — collected May 21, 2012 to May 20, 2013. The summary above covers all 629.

35 results from the 10 samples listed here: 6 detected, 29 not detected. Across the whole record it is 752 of 2,782. 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 Yazoo City, every result from 371 to 380 of 629 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
