Chemical and radiological sample results
MS0240005 , City of Long Beach
42 of the 74 analytes this system has been tested for have been detected at least once, across 1,032 samples on record.
The other 32 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 1,032 samples on record, detections range from December 31, 1992 to July 29, 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 181–190 of 1,032 samples, newest first — collected September 9, 2019 to December 17, 2019. The summary above covers all 1,032.
19 results from the 10 samples listed here: 7 detected, 12 not detected. Across the whole record it is 1,089 of 4,909. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
