Chemical and radiological sample results
MS0450006 , City of Canton
30 of the 64 analytes this system has been tested for have been detected at least once, across 559 samples on record.
The other 34 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 559 samples on record, detections range from July 16, 2002 to June 30, 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 311–320 of 559 samples, newest first — collected August 31, 2010 to May 17, 2011. The summary above covers all 559.
39 results from the 10 samples listed here: 24 detected, 15 not detected. Across the whole record it is 1,020 of 2,330. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
