Chemical and radiological sample results

MS0070016 , Poplar Springs W/A #1

22 of the 57 analytes this system has been tested for have been detected at least once, across 246 samples on record.

The other 35 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 246 samples on record, detections range from December 7, 1993 to August 11, 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 Poplar Springs W/A #1, 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 246 samples, newest first — collected January 18, 2011 to June 30, 2011. The summary above covers all 246.

37 results from the 10 samples listed here: 19 detected, 18 not detected. Across the whole record it is 310 of 1,113. 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 Poplar Springs W/A #1, every result from 141 to 150 of 246 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
