Chemical and radiological sample results
MS0200001 , Combined Utilities
38 of the 73 analytes this system has been tested for have been detected at least once, across 464 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 464 samples on record, detections range from September 8, 1993 to August 4, 2026. 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 441–450 of 464 samples, newest first — collected September 9, 1993 to March 15, 1994. The summary above covers all 464.
20 results from the 10 samples listed here: 16 detected, 4 not detected. Across the whole record it is 718 of 2,426. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
