Chemical and radiological sample results

MS0290004 , Houston-Palestine Water Assoc

18 of the 57 analytes this system has been tested for have been detected at least once, across 368 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 368 samples on record, detections range from August 9, 1993 to February 11, 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 Houston-Palestine Water Assoc, 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 281–290 of 368 samples, newest first — collected September 11, 2001 to January 28, 2004. The summary above covers all 368.

85 results from the 10 samples listed here: 14 detected, 71 not detected. Across the whole record it is 331 of 1,771. 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 Houston-Palestine Water Assoc, every result from 281 to 290 of 368 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
