| Details: | SUMMARY: CT Tracer Study DETAILS: The system owns and operates a surface water system that provides water to approximately 50 people through 22 connections. Water from Beaver Creek is treated by a pressure filter/cartridge filter plant prior to disinfection with sodium hyprochlorite. The system has two 9,000 gallon reservoirs that are used for storage and for contact time. HBH was contacted by Jon Woodward to provide assistance with a contact tracer study to determine the amount of contact time in the reservoirs before the first user. The tracer testing is complicated by the current lack of a delivery meter following the contact reservoir. I developed tracer study methodology. ACTION NEEDED: Perform tracer testing. | ||
