Hi Gerald,

Per the Recycled Water Class A permit "After disinfection, total coliform may not exceed:

--- A median of 2.2 organisms per 100 mL based on daily sampling over the last 7 days that analyses have been completed.

--- 23 organisms per 100 mL in any single sample.

The speculation as to why there was a high count for coliform that specific day (June 26th) is that the gun was located in a section on the Coleman field where there is cattle roaming. Unfortunately, there is no visual way to know if the cattle came in contact with the nozzle on the gun. It's possible that the cattle rubbed against it or licked the nozzle. Since this has occurred, we have taken additional precautions to avoid this situation again. The nozzle is disinfected everyday prior to taking the sample. The other possibility that we concluded was that the sample bottles that we were using were from last year. We have discarded those bottle and are using the most recent sample bottles.

Please let me know if you have any additional information that I can provide.

Thank you,

Jaimee Searcy
