Chemical and radiological sample results

MS0020003 , Farmington Water Association

28 of the 60 analytes this system has been tested for have been detected at least once, across 487 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 487 samples on record, detections range from July 1, 1992 to May 5, 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 Farmington 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 71–80 of 487 samples, newest first — collected January 20, 2021 to June 22, 2021. The summary above covers all 487.

16 results from the 10 samples listed here: 11 detected, 5 not detected. Across the whole record it is 703 of 1,675. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

We withheld the location of 6 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.

Chemical and radiological sample results for Farmington Water Association, every result from 71 to 80 of 487 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
