Chemical and radiological sample results
MS0250020 , City of Raymond
29 of the 57 analytes this system has been tested for have been detected at least once, across 590 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 590 samples on record, detections range from October 11, 1993 to February 23, 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 581–590 of 590 samples, newest first — collected October 11, 1993 to October 12, 1993. The summary above covers all 590.
20 results from the 10 samples listed here: 14 detected, 6 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
