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.

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.
