Chemical and radiological sample results

MS0540075 , Aci Building Systems, LLC

10 of the 50 analytes this system has been tested for have been detected at least once, across 147 samples on record.

The other 40 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 147 samples on record, detections range from April 5, 2022 to June 23, 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.

Every analyte ever detected for Aci Building Systems, LLC, 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 141–147 of 147 samples, newest first — collected April 5, 2022 to April 5, 2022. The summary above covers all 147.

14 results from the 7 samples listed here: 13 detected, 1 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 Aci Building Systems, LLC, every result from 141 to 147 of 147 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
