Chemical and radiological sample results

MS0780010 , Tomnolen Water Assn, Inc

33 of the 72 analytes this system has been tested for have been detected at least once, across 199 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 199 samples on record, detections range from November 3, 2003 to July 20, 2026. 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 Tomnolen Water Assn, Inc, 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 141–150 of 199 samples, newest first — collected September 6, 2011 to December 8, 2011. The summary above covers all 199.

43 results from the 10 samples listed here: 9 detected, 34 not detected. Across the whole record it is 171 of 1,020. 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 Tomnolen Water Assn, Inc, every result from 141 to 150 of 199 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
