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.

Every analyte ever detected for Lizana Elementary School, 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 261–270 of 270 samples, newest first — collected November 3, 1993 to April 6, 1994. The summary above covers all 270.

20 results from the 10 samples listed here: 18 detected, 2 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for Lizana Elementary School, every result from 261 to 270 of 270 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
