Chemical and radiological sample results
MS0690052 , Independence High School
27 of the 58 analytes this system has been tested for have been detected at least once, across 241 samples on record.
The other 31 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 241 samples on record, detections range from October 29, 2003 to June 30, 2026. 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 221–230 of 241 samples, newest first — collected September 28, 2005 to September 20, 2010. The summary above covers all 241.
43 results from the 10 samples listed here: 18 detected, 25 not detected. Across the whole record it is 295 of 1,368. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
Units in this table
Cyanide is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
