| Details: | SUMMARY: CT Tracer Study DETAILS: The London Water Company 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 hypochlorite. 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 reservoir before the first user. The tracer testing is complicated by the current lack of a delivery meter following the contact reservoir. I visited the water system to set up tracer study and gather flow data. ACTION NEEDED: Develop tracer study methodology and perform tracer study. | ||
