Chemical and radiological sample results

MS0380002 , Collinsville Water Assn

18 of the 57 analytes this system has been tested for have been detected at least once, across 232 samples on record.

The other 39 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 232 samples on record, detections range from September 29, 2003 to April 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.

Every analyte ever detected for Collinsville 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 231–232 of 232 samples, newest first — collected September 29, 2003 to September 29, 2003. The summary above covers all 232.

24 results from the 2 samples listed here: 6 detected, 18 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 Collinsville Water Assn, every result from 231 to 232 of 232 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
