This is a rebuild of Drinking Water Watch and not yet the official record. Use the agency’s current Drinking Water Watch for anything you need to rely on.

Samples for one analyte

Samples taken for Mercury across the water systems Mississippi State Department of Health serves — where it was looked for, and at which sampling point.

1,981–2,000 of 2,075 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 Mercury. 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.
