Details: SUMMARY: Corrosion Control Assistance DETAILS: The City of Newberg owns and operates the Oliver Springs water system. The springs were at one point connected to the City’s water system. The City remains responsible for the system and the system serves 40 people through 18 connections. Copper limits were exceeded in 2010. A limestone contactor had been proposed for the system. This selection was due to the fact that there is no power available at the spring site. DWP recommended a review of the selection of the limestone contactor prior to installation. The City of Newberg has requested assistance from HBH with this review. I met with Russ Reed to review the water quality parameters as well as a pH control pilot test that was completed by the City. Due to the fact that a limestone contactor is not the recommended approach based on EPA guidance, it was recommended the City look at the possibility of a copper corrosion pilot test if they remain determined to install a limestone contactor. ACTION NEEDED: Continue to coordinate between City and DWP.
