Chemical and radiological sample results

MS0150009 , Copiah-New Zion Water Assn,inc

41 of the 75 analytes this system has been tested for have been detected at least once, across 592 samples on record.

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 592 samples on record, detections range from November 11, 1993 to April 20, 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 Copiah-New Zion Water Assn,inc, 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 381–390 of 592 samples, newest first — collected July 21, 2009 to October 19, 2009. The summary above covers all 592.

40 results from the 10 samples listed here: 15 detected, 25 not detected. Across the whole record it is 669 of 3,437. 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 Copiah-New Zion Water Assn,inc, every result from 381 to 390 of 592 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
