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 Total Haloacetic Acids (Haa5) across the water systems Mississippi State Department of Health serves — where it was looked for, and at which sampling point.

921–940 of 4,242 samples. From samples collected September 28, 2024 to September 28, 2026. These dates are applied here by default; they are not a limit on what the agency records. Show 5 years, back to September 28, 2021.

This page can show a range of up to 5 years at a time. That is a limit of this service, not of what the agency records.

This is where it was looked for

Each row is a sample taken for Total Haloacetic Acids (Haa5). 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.

We withheld the location of 3 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.
