Chemical and radiological sample results
MS0050001 , Town of Ashland
22 of the 58 analytes this system has been tested for have been detected at least once, across 373 samples on record.
The other 36 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 373 samples on record, detections range from September 21, 1993 to November 12, 2025. These figures cover the whole record; the list of samples further down is narrowed.
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 21–21 of 21 samples, newest first — collected October 14, 2024 to October 14, 2024. The summary above covers all 21.
1 result from the 1 sample listed here: 1 detected, 0 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
