Chemical and radiological sample results
MS0540011 , Independence Water Association
18 of the 57 analytes this system has been tested for have been detected at least once, across 151 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 151 samples on record, detections range from October 13, 2003 to February 25, 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 91–100 of 151 samples, newest first — collected February 13, 2012 to June 3, 2013. The summary above covers all 151.
36 results from the 10 samples listed here: 10 detected, 26 not detected. Across the whole record it is 195 of 641. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
