Chemical and radiological sample results
MS0820004 , Central Yazoo #1 Fletchers CH.
26 of the 62 analytes this system has been tested for have been detected at least once, across 266 samples on record.
The other 36 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 266 samples on record, detections range from November 5, 2003 to July 15, 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 201–210 of 266 samples, newest first — collected July 23, 2007 to November 5, 2008. The summary above covers all 266.
53 results from the 10 samples listed here: 34 detected, 19 not detected. Across the whole record it is 460 of 1,405. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
