Chemical and radiological sample results
MS0410012 , Town of Saltillo
24 of the 57 analytes this system has been tested for have been detected at least once, across 750 samples on record.
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 October 1, 2003 to December 15, 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 601–610 of 750 samples, newest first — collected July 20, 2010 to September 19, 2011. The summary above covers all 750.
35 results from the 10 samples listed here: 6 detected, 29 not detected. Across the whole record it is 899 of 2,408. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
