Chemical and radiological sample results
MS0390015 , Mt Zion W/A
9 of the 13 analytes this system has been tested for have been detected at least once, across 87 samples on record.
The other 4 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 87 samples on record, detections range from June 30, 2004 to August 12, 2024. 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.
