Chemical and radiological sample results
MS0260027 , West Holmes Water Association
22 of the 57 analytes this system has been tested for have been detected at least once, across 360 samples on record.
The other 35 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 360 samples on record, detections range from February 28, 1996 to November 3, 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 191–200 of 360 samples, newest first — collected June 19, 2007 to September 24, 2007. The summary above covers all 360.
27 results from the 10 samples listed here: 22 detected, 5 not detected. Across the whole record it is 365 of 1,527. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
