Chemical and radiological sample results

MS0150019 , Highway I-55 Rest Area

3 of the 4 analytes this system has been tested for have been detected at least once, across 22 samples on record.

The other 1 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 22 samples on record, detections range from July 18, 2005 to February 1, 2021. 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 Highway I-55 Rest Area, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.
Analyte Kind Detected in First detected Last detected

The most recent samples, result by result

The table below lists 1–10 of 22 samples, newest first — collected January 25, 2017 to January 29, 2025. The summary above covers all 22.

28 results from the 10 samples listed here: 1 detected, 27 not detected. Across the whole record it is 5 of 64. 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 Highway I-55 Rest Area, every result from 1 to 10 of 22 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
