Hi Randy,

Thank you for the information. I was also wondering about the temperature gauge at the WTP pump house. Is this also ready for final installation? And is there a way for the temperature to be accessed and recorded at the WWTP?

Hi Jennifer,

This morning John and I were out at the treatment plant. He was checking control panels for spare relays and terminals for the drive signal modifications and I picked up the Lab Data. The pH meter values are tracking the grab sample pH values very well. I would recommend proceeding with the installation based on the past several weeks of data. Please review the attached table and chart. Also is a pdf copy if you need to send it off to DEQ.

Thanks for gathering the data for us.

Randy
