Chemical and radiological sample results
MS0460013 , West Marion Water Association
19 of the 56 analytes this system has been tested for have been detected at least once, across 241 samples on record.
The other 37 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 241 samples on record, detections range from October 8, 2003 to July 7, 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.

The most recent samples, result by result
The table below lists 241–241 of 241 samples, newest first — collected October 8, 2003 to October 8, 2003. The summary above covers all 241.
1 result from the 1 sample listed here: 0 detected, 1 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
