| Details: | SUMMARY: CT Tracer Study DETAILS: The system owns and operates a surface water system that provides water to 1,900 people through 840 connections. Water from the North Santiam River is treated by a slow sand filter water treatment plant prior to disinfection with gaseous chlorine. HBH was contacted by the district to provide assistance with a contact tracer study to determine the amount of contact time in the treatment plant clearwell before the first user. I met with operator at water treatment plant to determine methodology for the tracer testing. ACTION NEEDED: Develop methodology and perform tracer testing. | ||
