Chemical and radiological sample results

MS0610036 , PRVWSD-Pelahatchie Bay

40 of the 75 analytes this system has been tested for have been detected at least once, across 651 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 651 samples on record, detections range from October 20, 2003 to September 3, 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 PRVWSD-Pelahatchie Bay, 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 521–530 of 651 samples, newest first — collected February 3, 2010 to June 29, 2010. The summary above covers all 651.

57 results from the 10 samples listed here: 30 detected, 27 not detected. Across the whole record it is 1,115 of 2,808. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Units in this table

Gross Alpha Particle Activity is recorded on this page in mg/l and pci/l.

Radium-226 is recorded on this page in mg/l and pci/l.

Radium-228 is recorded on this page in mg/l and pci/l.

Chemical and radiological sample results for PRVWSD-Pelahatchie Bay, every result from 521 to 530 of 651 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
