Chemical and radiological sample results
MS0370011 , West Lamar Water Assn #1
30 of the 60 analytes this system has been tested for have been detected at least once, across 750 samples on record.
The other 30 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 750 samples on record, detections range from September 29, 2003 to July 6, 2026. 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 31–40 of 750 samples, newest first — collected June 25, 2024 to October 21, 2024. The summary above covers all 750.
19 results from the 10 samples listed here: 14 detected, 5 not detected. Across the whole record it is 818 of 4,862. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
We withheld the location of 7 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 The location on record identifies a private home, and we do not publish those.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.
