Chemical and radiological sample results

MS0230065 , Hancock County Water & Sewer

28 of the 56 analytes this system has been tested for have been detected at least once, across 774 samples on record.

The other 28 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 774 samples on record, detections range from June 25, 2002 to July 28, 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 Hancock County Water & Sewer, 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 731–740 of 774 samples, newest first — collected October 19, 2004 to November 4, 2004. The summary above covers all 774.

39 results from the 10 samples listed here: 18 detected, 21 not detected. Across the whole record it is 1,566 of 3,571. 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 Hancock County Water & Sewer, every result from 731 to 740 of 774 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
