Chemical and radiological sample results
MS0040011 , Zama Water Association
23 of the 58 analytes this system has been tested for have been detected at least once, across 146 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 146 samples on record, detections range from November 30, 1993 to January 16, 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 146 samples, newest first — collected March 4, 2015 to August 28, 2017. The summary above covers all 146.
38 results from the 10 samples listed here: 18 detected, 20 not detected. Across the whole record it is 187 of 601. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
