Chemical and radiological sample results
MS0310025 , Lake Eddins Poa WTR & SWR Inc
35 of the 73 analytes this system has been tested for have been detected at least once, across 245 samples on record.
The other 38 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 245 samples on record, detections range from September 24, 2003 to November 4, 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 161–170 of 245 samples, newest first — collected December 14, 2011 to July 10, 2012. The summary above covers all 245.
33 results from the 10 samples listed here: 9 detected, 24 not detected. Across the whole record it is 414 of 778. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
