Chemical and radiological sample results

MS0160003 , Town of Mount Olive

20 of the 58 analytes this system has been tested for have been detected at least once, across 259 samples on record.

The other 38 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 259 samples on record, detections range from October 12, 1993 to February 23, 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 Town of Mount Olive, 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 121–130 of 259 samples, newest first — collected June 16, 2010 to July 13, 2011. The summary above covers all 259.

68 results from the 10 samples listed here: 11 detected, 57 not detected. Across the whole record it is 239 of 1,268. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
