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.

Every analyte ever detected for Town of Saltillo, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 61–70 of 750 samples, newest first — collected June 13, 2023 to October 18, 2023. The summary above covers all 750.

14 results from the 10 samples listed here: 12 detected, 2 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.

We withheld the location of 6 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 The location on record identifies a private home, and we do not publish those.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.

Chemical and radiological sample results for Town of Saltillo, every result from 61 to 70 of 750 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
