Chemical and radiological sample results

MS0330002 , Carson Central Water Assn

17 of the 59 analytes this system has been tested for have been detected at least once, across 187 samples on record.

The other 42 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 187 samples on record, detections range from September 24, 2003 to February 24, 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 Carson Central Water Assn, 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 181–187 of 187 samples, newest first — collected April 9, 2002 to April 27, 2004. The summary above covers all 187.

69 results from the 7 samples listed here: 4 detected, 65 not detected. 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 Carson Central Water Assn, every result from 181 to 187 of 187 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
