Chemical and radiological sample results

MS0550062 , PRCUA-Hillsdale Water System

17 of the 55 analytes this system has been tested for have been detected at least once, across 160 samples on record.

The other 38 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 160 samples on record, detections range from September 2, 2010 to February 24, 2025. 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 PRCUA-Hillsdale Water System, 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 81–90 of 160 samples, newest first — collected September 29, 2014 to November 3, 2015. The summary above covers all 160.

59 results from the 10 samples listed here: 10 detected, 49 not detected. Across the whole record it is 170 of 1,350. 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 PRCUA-Hillsdale Water System, every result from 81 to 90 of 160 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
