Chemical and radiological sample results

MS0820024 , CF Industries Nitrogen, LLC

19 of the 53 analytes this system has been tested for have been detected at least once, across 211 samples on record.

The other 34 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 211 samples on record, detections range from November 5, 2003 to February 14, 2024. These figures cover the whole record; the list of samples further down is narrowed.

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 CF Industries Nitrogen, LLC, 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 4 samples collected between September 25, 2024 and September 25, 2026 are listed below, newest first.

9 results from the 4 samples listed here: 0 detected, 9 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 CF Industries Nitrogen, LLC, every result from the 4 samples on record, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
