Chemical and radiological sample results

MS0520023 , Parks Utilities

13 of the 57 analytes this system has been tested for have been detected at least once, across 151 samples on record.

The other 44 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 151 samples on record, detections range from October 13, 2003 to September 29, 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 Parks Utilities, 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 21–30 of 151 samples, newest first — collected September 12, 2023 to April 3, 2024. The summary above covers all 151.

59 results from the 10 samples listed here: 13 detected, 46 not detected. Across the whole record it is 139 of 683. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

We withheld the location of 5 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.

Chemical and radiological sample results for Parks Utilities, every result from 21 to 30 of 151 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
