Chemical and radiological sample results
MS0680004 , East Charleston Water Assn
6 of the 13 analytes this system has been tested for have been detected at least once, across 84 samples on record.
The other 7 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 84 samples on record, detections range from June 18, 2007 to September 8, 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.
| Analyte | Kind | Detected in | First detected | Last detected |
|---|---|---|---|---|
| Copper, Free 1022 | Inorganic Chemical | 68 of 68 results | Jul 12, 2007 | Sep 8, 2025 |
| Lead 1030 | Inorganic Chemical | 38 of 68 results | Jul 12, 2007 | Sep 8, 2025 |
| Total Haloacetic Acids (Haa5) 2456 | Organic Chemical | 5 of 8 results | Jun 18, 2007 | Feb 27, 2024 |
| TTHM 2950 | Organic Chemical | 5 of 8 results | Jun 18, 2007 | Feb 27, 2024 |
| Dichloroacetic Acid 2451 | Organic Chemical | 4 of 5 results | Jul 7, 2008 | Jul 21, 2014 |
| Chloroform 2941 | Organic Chemical | 3 of 6 results | Jul 7, 2008 | Jun 27, 2011 |

The most recent samples, result by result
The table below lists 11–20 of 84 samples, newest first — collected September 23, 2020 to February 27, 2024. The summary above covers all 84.
18 results from the 10 samples listed here: 15 detected, 3 not detected. Across the whole record it is 123 of 201. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
Units in this table
Lead is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
We withheld the location of 5 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.
