Chemical and radiological sample results

MS0240009 , City of Pass Christian

44 of the 74 analytes this system has been tested for have been detected at least once, across 686 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 686 samples on record, detections range from July 28, 1992 to May 18, 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 Pass Christian, 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 401–410 of 686 samples, newest first — collected April 18, 2007 to August 30, 2007. The summary above covers all 686.

63 results from the 10 samples listed here: 10 detected, 53 not detected. Across the whole record it is 981 of 3,062. 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 Pass Christian, every result from 401 to 410 of 686 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
