Chemical and radiological sample results

MS0540001 , Asl Water Association

21 of the 56 analytes this system has been tested for have been detected at least once, across 167 samples on record.

The other 35 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 167 samples on record, detections range from October 13, 2003 to December 7, 2022. 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.

Every analyte ever detected for Asl Water Association, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.
