Chemical and radiological sample results

MS0160004 , North Covington W/A-North

18 of the 58 analytes this system has been tested for have been detected at least once, across 373 samples on record.

The other 40 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 373 samples on record, detections range from July 12, 1993 to February 11, 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 North Covington W/A-North, 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 371–373 of 373 samples, newest first — collected July 12, 1993 to July 12, 1993. The summary above covers all 373.

6 results from the 3 samples listed here: 1 detected, 5 not detected. 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 North Covington W/A-North, every result from 371 to 373 of 373 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
