Chemical and radiological sample results
MS0170009 , City of Hernando
25 of the 60 analytes this system has been tested for have been detected at least once, across 435 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 435 samples on record, detections range from December 28, 1993 to February 24, 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 351–360 of 435 samples, newest first — collected July 26, 2000 to January 14, 2004. The summary above covers all 435.
58 results from the 10 samples listed here: 17 detected, 41 not detected. Across the whole record it is 519 of 1,323. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
