Chemical and radiological sample results
MS0240144 , Delisle Elementary School
11 of the 46 analytes this system has been tested for have been detected at least once, across 179 samples on record.
The other 35 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 179 samples on record, detections range from October 26, 1993 to August 13, 2009. 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 111–120 of 179 samples, newest first — collected May 29, 2002 to December 11, 2002. The summary above covers all 179.
20 results from the 10 samples listed here: 18 detected, 2 not detected. Across the whole record it is 272 of 521. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
