Chemical and radiological sample results

MS0680004 , East Charleston Water Assn

6 of the 13 analytes this system has been tested for have been detected at least once, across 84 samples on record.

The other 7 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 84 samples on record, detections range from June 18, 2007 to September 8, 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 East Charleston Water Assn, 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 41–50 of 84 samples, newest first — collected July 25, 2017 to May 8, 2018. The summary above covers all 84.

27 results from the 10 samples listed here: 16 detected, 11 not detected. Across the whole record it is 123 of 201. 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 East Charleston Water Assn, every result from 41 to 50 of 84 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
