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; the list of samples further down is narrowed.
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.
