Chemical and radiological sample results

MS0090005 , City of Houston

20 of the 58 analytes this system has been tested for have been detected at least once, across 540 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 540 samples on record, detections range from July 3, 1992 to July 30, 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.

Every analyte ever detected for City of Houston, 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 351–360 of 540 samples, newest first — collected January 28, 2004 to May 10, 2004. The summary above covers all 540.

116 results from the 10 samples listed here: 0 detected, 116 not detected. Across the whole record it is 712 of 1,935. 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 Houston, every result from 351 to 360 of 540 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
