Chemical and radiological sample results
MS0340018 , Sharon Water Works
26 of the 58 analytes this system has been tested for have been detected at least once, across 372 samples on record.
The other 32 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 372 samples on record, detections range from September 24, 2003 to February 24, 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.

The most recent samples, result by result
The table below lists 291–300 of 372 samples, newest first — collected September 18, 2006 to July 31, 2007. The summary above covers all 372.
24 results from the 10 samples listed here: 23 detected, 1 not detected. Across the whole record it is 422 of 2,220. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
