6 of the 13 analytes this system has been tested for have been detected at least once, across 46 samples on record.
The other 7 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 46 samples on record, detections range from July 10, 2008 to March 25, 2025. 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.
| Analyte | Kind | Detected in | First detected | Last detected |

The most recent samples, result by result
The 5 samples collected between September 25, 2024 and September 25, 2026 are listed below, newest first.
10 results from the 5 samples listed here: 2 detected, 8 not detected. 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 2 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 The location on record identifies a private home, and we do not publish those.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.
