Chemical and radiological sample results
MS0420004 , Morgan City Water & Sewer Assn
30 of the 73 analytes this system has been tested for have been detected at least once, across 114 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 114 samples on record, detections range from October 1, 2003 to March 17, 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 61–70 of 114 samples, newest first — collected June 13, 2011 to September 5, 2012. The summary above covers all 114.
36 results from the 10 samples listed here: 11 detected, 25 not detected. Across the whole record it is 121 of 521. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
