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; the list of samples further down is narrowed.

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.

Every analyte ever detected for City of Long Beach, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 31–33 of 33 samples, newest first — collected December 3, 2024 to February 3, 2025. The summary above covers all 33.

7 results from the 3 samples listed here: 1 detected, 6 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for City of Long Beach, every result from 31 to 33 of 33 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
