Chemical and radiological sample results

MS0530010 , Town of Maben

21 of the 57 analytes this system has been tested for have been detected at least once, across 214 samples on record.

The other 36 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 214 samples on record, detections range from October 15, 2003 to July 13, 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 Maben, 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 51–60 of 214 samples, newest first — collected September 29, 2020 to October 19, 2021. The summary above covers all 214.

26 results from the 10 samples listed here: 11 detected, 15 not detected. Across the whole record it is 324 of 1,036. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Units in this table

Total Haloacetic Acids (Haa5) is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

Chemical and radiological sample results for Town of Maben, every result from 51 to 60 of 214 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
