The most recent samples

No date range is applied: this list draws on every sample on record. Show the last two years only.

The list below shows 76–90 of 296 samples on record, newest first.

Routine (12) and Repeat (3).

We withheld the location of 1 sampling point 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 The location on record identifies a private home, and we do not publish those.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.

Coliform and microbial sample results for Deeson-Roundlake Water Corp, 76 to 90 of 296 samples shown, newest first. A result is a presence-or-absence verdict and carries no measured amount.
