Chemical and radiological sample results
MS0010015 , Adams Co W/A #4-Kaiser Lake
46 of the 75 analytes this system has been tested for have been detected at least once, across 668 samples on record.
The other 29 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 668 samples on record, detections range from September 1, 1992 to April 21, 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 161–170 of 668 samples, newest first — collected June 13, 2018 to November 6, 2018. The summary above covers all 668.
45 results from the 10 samples listed here: 16 detected, 29 not detected. Across the whole record it is 1,038 of 2,841. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
