Chemical and radiological sample results
MS0300005 , City of Ocean Springs
48 of the 77 analytes this system has been tested for have been detected at least once, across 787 samples on record.
The other 29 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 787 samples on record, detections range from July 30, 2002 to June 29, 2026. These figures cover the whole record; the list of samples further down is narrowed.
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 41–43 of 43 samples, newest first — collected January 14, 2025 to January 14, 2025. The summary above covers all 43.
3 results from the 3 samples listed here: 0 detected, 3 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
