Chemical and radiological sample results
MS0370006 , North Lamar Water Association
34 of the 60 analytes this system has been tested for have been detected at least once, across 731 samples on record.
The other 26 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 731 samples on record, detections range from September 29, 2003 to July 6, 2026. 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 11–20 of 33 samples, newest first — collected February 25, 2025 to September 2, 2025. The summary above covers all 33.
40 results from the 10 samples listed here: 4 detected, 36 not detected. Across the whole record it is 817 of 3,913. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
