| 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. | ||
