Chemical and radiological sample results
MS0340021 , City of Laurel
30 of the 61 analytes this system has been tested for have been detected at least once, across 670 samples on record.
The other 31 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 670 samples on record, detections range from July 30, 2002 to April 21, 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 21–22 of 22 samples, newest first — collected February 5, 2025 to February 5, 2025. The summary above covers all 22.
2 results from the 2 samples listed here: 2 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.
