Chemical and radiological sample results

MS0220053 , U S Engineers-North Graysport

4 of the 4 analytes this system has been tested for have been detected at least once, across 23 samples on record.

The other 0 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 23 samples on record, detections range from November 30, 2004 to February 10, 2021. 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 U S Engineers-North Graysport, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.
Analyte Kind Detected in First detected Last detected

The most recent samples, result by result

The table below lists 11–20 of 23 samples, newest first — collected April 18, 2007 to March 28, 2016. The summary above covers all 23.

30 results from the 10 samples listed here: 0 detected, 30 not detected. Across the whole record it is 4 of 67. 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 U S Engineers-North Graysport, every result from 11 to 20 of 23 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
