Chemical and radiological sample results
MS0030006 , Pine Street Water Association
6 of the 14 analytes this system has been tested for have been detected at least once, across 116 samples on record.
The other 8 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 116 samples on record, detections range from November 29, 1993 to August 13, 2024. 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.
| Analyte | Kind | Detected in | First detected | Last detected |
|---|---|---|---|---|
| Copper, Free 1022 | Inorganic Chemical | 69 of 98 results | Sep 18, 2000 | Aug 13, 2024 |
| Lead 1030 | Inorganic Chemical | 39 of 98 results | Nov 29, 1993 | Aug 13, 2024 |
| Total Haloacetic Acids (Haa5) 2456 | Organic Chemical | 3 of 9 results | Jun 25, 2007 | Jul 7, 2011 |
| TTHM 2950 | Organic Chemical | 3 of 8 results | May 3, 2004 | Jun 1, 2010 |
| Monobromoacetic Acid 2453 | Organic Chemical | 1 of 5 results | Jul 7, 2011 | Jul 7, 2011 |
| Chloroform 2941 | Organic Chemical | 1 of 5 results | Jun 1, 2010 | Jun 1, 2010 |

The most recent samples, result by result
The table below lists 51–60 of 116 samples, newest first — collected July 7, 2011 to April 9, 2015. The summary above covers all 116.
35 results from the 10 samples listed here: 13 detected, 22 not detected. Across the whole record it is 116 of 259. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
