Chemical and radiological sample results

MS0610009 , Town of Florence

42 of the 74 analytes this system has been tested for have been detected at least once, across 473 samples on record.

The other 32 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 473 samples on record, detections range from October 20, 2003 to June 24, 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 Town of Florence, 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 471–473 of 473 samples, newest first — collected October 20, 2003 to October 20, 2003. The summary above covers all 473.

36 results from the 3 samples listed here: 12 detected, 24 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 Town of Florence, every result from 471 to 473 of 473 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
