Chemical and radiological sample results
MS0420041 , Blue Lake Water Assn. Inc
10 of the 13 analytes this system has been tested for have been detected at least once, across 59 samples on record.
The other 3 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 59 samples on record, detections range from September 23, 2004 to May 7, 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 21–30 of 59 samples, newest first — collected July 23, 2014 to June 27, 2017. The summary above covers all 59.
23 results from the 10 samples listed here: 14 detected, 9 not detected. Across the whole record it is 98 of 154. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
