Chemical and radiological sample results
MS0670001 , Big Yeager Water Association
22 of the 58 analytes this system has been tested for have been detected at least once, across 125 samples on record.
The other 36 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 125 samples on record, detections range from October 27, 2003 to April 2, 2025. 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 5 samples collected between September 25, 2024 and September 25, 2026 are listed below, newest first.
16 results from the 5 samples listed here: 4 detected, 12 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
