Chemical and radiological sample results
MS0340003 , City of Ellisville
41 of the 69 analytes this system has been tested for have been detected at least once, across 480 samples on record.
The other 28 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 480 samples on record, detections range from September 29, 2003 to August 25, 2025. 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 261–270 of 480 samples, newest first — collected June 4, 2013 to July 24, 2013. The summary above covers all 480.
46 results from the 10 samples listed here: 21 detected, 25 not detected. Across the whole record it is 678 of 3,354. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
