Chemical and radiological sample results
MS0440079 , Sheriff Boys Ranch
10 of the 50 analytes this system has been tested for have been detected at least once, across 24 samples on record.
The other 40 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 24 samples on record, detections range from October 6, 2003 to September 5, 2007. 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.
