Chemical and radiological sample results

MS0610008 , Fannin Water Assn-North

34 of the 65 analytes this system has been tested for have been detected at least once, across 577 samples on record.

The other 31 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 577 samples on record, detections range from November 24, 2003 to July 29, 2026. These figures cover the whole record; the list of samples further down is narrowed.

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 Fannin Water Assn-North, 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 31–40 of 43 samples, newest first — collected March 13, 2025 to April 2, 2025. The summary above covers all 43.

80 results from the 10 samples listed here: 8 detected, 72 not detected. Across the whole record it is 597 of 4,539. 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 Fannin Water Assn-North, every result from 31 to 40 of 43 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
