Chemical and radiological sample results

MS0260022 , Harland Creek Community W/A-B

27 of the 59 analytes this system has been tested for have been detected at least once, across 478 samples on record.

The other 32 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 478 samples on record, detections range from September 2, 1993 to February 11, 2026. These figures cover the whole record.

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 Harland Creek Community W/A-B, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 161–170 of 478 samples, newest first — collected February 11, 2015 to February 13, 2017. The summary above covers all 478.

72 results from the 10 samples listed here: 8 detected, 64 not detected. Across the whole record it is 563 of 2,888. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for Harland Creek Community W/A-B, every result from 161 to 170 of 478 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
