FYI – this work is as part of the NPDES requirements. We will also have the required temperature gauge at the river up and running once the permanent installation is complete and the VPN connection is made.

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
