Chemical and radiological sample results

MS0250021 , Reedtown Water Assn

51 of the 77 analytes this system has been tested for have been detected at least once, across 652 samples on record.

The other 26 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 652 samples on record, detections range from July 13, 1993 to June 23, 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 Reedtown 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 31–40 of 652 samples, newest first — collected September 26, 2022 to October 25, 2023. The summary above covers all 652.

42 results from the 10 samples listed here: 1 detected, 41 not detected. Across the whole record it is 645 of 4,946. 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 Reedtown Water Assn, every result from 31 to 40 of 652 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
