Chemical and radiological sample results
MS0770002 , Clara Water Association
35 of the 74 analytes this system has been tested for have been detected at least once, across 1,031 samples on record.
The other 39 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 1,031 samples on record, detections range from November 3, 2003 to August 6, 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 1,031–1,031 of 1,031 samples, newest first — collected March 27, 2002 to March 27, 2002. The summary above covers all 1,031.
21 results from the 1 sample listed here: 0 detected, 21 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
