Chemical and radiological sample results

MS0060049 , Deeson-Roundlake Water Corp

26 of the 59 analytes this system has been tested for have been detected at least once, across 267 samples on record.

The other 33 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 267 samples on record, detections range from June 7, 1994 to March 3, 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.

Every analyte ever detected for Deeson-Roundlake Water Corp, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 171–180 of 267 samples, newest first — collected May 29, 2002 to December 9, 2002. The summary above covers all 267.

30 results from the 10 samples listed here: 22 detected, 8 not detected. Across the whole record it is 414 of 818. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for Deeson-Roundlake Water Corp, every result from 171 to 180 of 267 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
