Chemical and radiological sample results
MS0360017 , Yocona Water Association, Inc.
18 of the 57 analytes this system has been tested for have been detected at least once, across 214 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 214 samples on record, detections range from September 29, 2003 to July 13, 2026. These figures cover the whole record; the list of samples further down is narrowed.
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 31–32 of 32 samples, newest first — collected November 12, 2024 to November 12, 2024. The summary above covers all 32.
32 results from the 2 samples listed here: 3 detected, 29 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
