Chemical and radiological sample results
MS0040012 , Mississippi Water Company
11 of the 13 analytes this system has been tested for have been detected at least once, across 184 samples on record.
The other 2 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 184 samples on record, detections range from August 25, 1993 to December 19, 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 31–40 of 184 samples, newest first — collected September 18, 2019 to June 14, 2022. The summary above covers all 184.
18 results from the 10 samples listed here: 11 detected, 7 not detected. Across the whole record it is 205 of 493. 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
Lead is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
