Samples for one analyte
Samples taken for Nitrate across the water systems Mississippi State Department of Health serves — where it was looked for, and at which sampling point.
2,641–2,660 of 3,153 samples. From samples collected October 1, 2024 to October 1, 2026. These dates are applied here by default; they are not a limit on what the agency records. Show 5 years, back to October 1, 2021.

This is where it was looked for
Each row is a sample taken for Nitrate. 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.
