Samples for one analyte
Samples taken for Cyanide across the water systems Mississippi State Department of Health serves — where it was looked for, and at which sampling point.
1,621–1,640 of 2,118 samples. From samples collected September 30, 2024 to September 30, 2026. These dates are applied here by default; they are not a limit on what the agency records. Show 5 years, back to September 30, 2021.

This is where it was looked for
Each row is a sample taken for Cyanide. These rows carry no result and no measured amount — a row means the analyte was sampled for at that point, not that it was found there.
Which analytes a system has detected, and when, is on that system’s own sample results page, reachable from its record.
