Samples for one analyte

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

641–660 of 4,782 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 is where it was looked for

Each row is a sample taken for Copper, Free. 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 15 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 The location on record identifies a private home, and we do not publish those.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.

Samples taken for Copper, Free across the systems Mississippi State Department of Health serves, 641 to 660 of 4,782 samples shown. Each row is a sample and carries no result: it says where the analyte was looked for, not what was found.
