Chemical and radiological sample results

MS0250003 , City of Clinton

49 of the 77 analytes this system has been tested for have been detected at least once, across 1,643 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 1,643 samples on record, detections range from July 20, 1992 to February 25, 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 Clinton, 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 511–520 of 1,643 samples, newest first — collected July 18, 2018 to July 18, 2018. The summary above covers all 1,643.

20 results from the 10 samples listed here: 16 detected, 4 not detected. Across the whole record it is 2,665 of 8,082. 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 Clinton, every result from 511 to 520 of 1,643 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
