Chemical and radiological sample results
MS0260018 , West Hill Water Association
9 of the 13 analytes this system has been tested for have been detected at least once, across 86 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 86 samples on record, detections range from November 1, 1993 to February 26, 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.
What has been detected, ever
