Chemical and radiological sample results

MS0580007 , Randolph Water Association #1

21 of the 58 analytes this system has been tested for have been detected at least once, across 297 samples on record.

The other 37 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 297 samples on record, detections range from October 15, 2003 to August 19, 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 Randolph Water Association #1, 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 71–80 of 297 samples, newest first — collected November 2, 2020 to September 15, 2021. The summary above covers all 297.

87 results from the 10 samples listed here: 2 detected, 85 not detected. Across the whole record it is 324 of 1,587. 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 Randolph Water Association #1, every result from 71 to 80 of 297 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
