Chemical and radiological sample results

MS0410001 , North Lee W/A-Auburn System #1

39 of the 72 analytes this system has been tested for have been detected at least once, across 244 samples on record.

The other 33 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 244 samples on record, detections range from October 6, 2003 to July 8, 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 North Lee W/A-Auburn System #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 111–120 of 244 samples, newest first — collected July 30, 2014 to August 17, 2015. The summary above covers all 244.

45 results from the 10 samples listed here: 14 detected, 31 not detected. Across the whole record it is 295 of 1,402. 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 North Lee W/A-Auburn System #1, every result from 111 to 120 of 244 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
