Chemical and radiological sample results
MS0790036 , Bleakhouse Water Association #2
9 of the 13 analytes this system has been tested for have been detected at least once, across 88 samples on record.
The other 4 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 88 samples on record, detections range from June 25, 2008 to April 30, 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.

The most recent samples, result by result
The table below lists 31–40 of 88 samples, newest first — collected June 2, 2010 to July 21, 2014. The summary above covers all 88.
31 results from the 10 samples listed here: 23 detected, 8 not detected. Across the whole record it is 173 of 205. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

| 0 mg/l This result is recorded as a detection, and the figure the agency wrote — "0.00" — is zero to the precision it was written to. Read the zero as "smaller than the written figure resolves", not as "none present".
