Chemical and radiological sample results

MS0410023 , Natchez Trace Parkway

38 of the 67 analytes this system has been tested for have been detected at least once, across 216 samples on record.

The other 29 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 216 samples on record, detections range from October 1, 2003 to March 10, 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 Natchez Trace Parkway, 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 211–216 of 216 samples, newest first — collected October 1, 2003 to February 9, 2004. The summary above covers all 216.

68 results from the 6 samples listed here: 11 detected, 57 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 Natchez Trace Parkway, every result from 211 to 216 of 216 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
