Chemical and radiological sample results

MS0510005 , Duffee Water Association

32 of the 72 analytes this system has been tested for have been detected at least once, across 173 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 173 samples on record, detections range from October 13, 2003 to December 2, 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 Duffee Water Association, 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 171–173 of 173 samples, newest first — collected October 13, 2003 to February 17, 2004. The summary above covers all 173.

34 results from the 3 samples listed here: 3 detected, 31 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 Duffee Water Association, every result from 171 to 173 of 173 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
