Chemical and radiological sample results
MS0240194 , Riverbend Utilities Inc
35 of the 72 analytes this system has been tested for have been detected at least once, across 288 samples on record.
The other 37 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 288 samples on record, detections range from November 23, 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.

The most recent samples, result by result
The table below lists 171–180 of 288 samples, newest first — collected July 19, 2011 to February 14, 2012. The summary above covers all 288.
23 results from the 10 samples listed here: 7 detected, 16 not detected. Across the whole record it is 345 of 1,489. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
Units in this table
Cyanide is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
