Chemical and radiological sample results
MS0270019 , Humphreys Co. W/A #3-Jaketown
19 of the 57 analytes this system has been tested for have been detected at least once, across 217 samples on record.
The other 38 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 217 samples on record, detections range from August 2, 1993 to October 28, 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.

The most recent samples, result by result
The table below lists 61–70 of 217 samples, newest first — collected September 24, 2014 to June 27, 2017. The summary above covers all 217.
34 results from the 10 samples listed here: 12 detected, 22 not detected. Across the whole record it is 248 of 753. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
