Chemical and radiological sample results
MS0240135 , Lizana Elementary School
35 of the 67 analytes this system has been tested for have been detected at least once, across 270 samples on record.
The other 32 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 270 samples on record, detections range from November 3, 1993 to March 31, 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 91–100 of 270 samples, newest first — collected August 26, 2014 to February 11, 2015. The summary above covers all 270.
29 results from the 10 samples listed here: 12 detected, 17 not detected. Across the whole record it is 303 of 1,956. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
