Chemical and radiological sample results
MS0630003 , Delta City Utility District
42 of the 72 analytes this system has been tested for have been detected at least once, across 469 samples on record.
The other 30 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 469 samples on record, detections range from November 17, 2003 to February 17, 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 301–310 of 469 samples, newest first — collected February 16, 2012 to July 17, 2012. The summary above covers all 469.
35 results from the 10 samples listed here: 7 detected, 28 not detected. Across the whole record it is 992 of 3,067. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
