Chemical and radiological sample results
MS0350024 , Porterville W/A-Kemper Springs
20 of the 59 analytes this system has been tested for have been detected at least once, across 284 samples on record.
The other 39 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 284 samples on record, detections range from September 24, 2003 to March 5, 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 131–140 of 284 samples, newest first — collected November 6, 2013 to February 20, 2014. The summary above covers all 284.
20 results from the 10 samples listed here: 18 detected, 2 not detected. Across the whole record it is 410 of 832. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
