Chemical and radiological sample results

MS0610023 , City of Richland

29 of the 61 analytes this system has been tested for have been detected at least once, across 630 samples on record.

The other 32 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 630 samples on record, detections range from October 20, 2003 to July 22, 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 City of Richland, 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 331–340 of 630 samples, newest first — collected June 13, 2016 to July 19, 2016. The summary above covers all 630.

39 results from the 10 samples listed here: 11 detected, 28 not detected. Across the whole record it is 680 of 3,007. 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 Richland, every result from 331 to 340 of 630 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
