Chemical and radiological sample results

MS0700003 , Chalybeate Water Assn

19 of the 57 analytes this system has been tested for have been detected at least once, across 266 samples on record.

The other 38 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 266 samples on record, detections range from October 29, 2003 to May 13, 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 Chalybeate 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 261–266 of 266 samples, newest first — collected October 29, 2003 to October 29, 2003. The summary above covers all 266.

39 results from the 6 samples listed here: 12 detected, 27 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 Chalybeate Water Assn, every result from 261 to 266 of 266 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
