Chemical and radiological sample results

MS0660021 , Magnolia Water Association

18 of the 53 analytes this system has been tested for have been detected at least once, across 192 samples on record.

The other 35 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 192 samples on record, detections range from November 12, 2003 to July 16, 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 Magnolia 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 31–40 of 192 samples, newest first — collected October 18, 2022 to August 31, 2023. The summary above covers all 192.

54 results from the 10 samples listed here: 11 detected, 43 not detected. Across the whole record it is 215 of 909. 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 4 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 The location on record identifies a private home, and we do not publish those.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 Magnolia Water Association, every result from 31 to 40 of 192 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
