Chemical and radiological sample results
MS0710005 , Town of Golden Water Dept
16 of the 103 analytes this system has been tested for have been detected at least once, across 179 samples on record.
The other 87 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 179 samples on record, detections range from October 29, 2003 to August 20, 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 81–90 of 179 samples, newest first — collected September 10, 2014 to August 23, 2016. The summary above covers all 179.
27 results from the 10 samples listed here: 11 detected, 16 not detected. Across the whole record it is 189 of 775. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
